December 30, 2012, Recent Developments

Before this year ends we want to use the occasion and give you some news about recent developments in FFmpeg.

- subtitles filter

The subtitles filter makes it possible to merge subtitles supported by libavformat/libavcodec into a video stream. This process is also known as burning them into the video or simply hardsubbing. This filter depends on libass and thus is only available in builds configured with --enable-ass.

The subtitles filter is also useful to play external subtitle files with ffplay. An example of this usage can be found in the following entry about TED captions.

- JSON captions for TED talks decoding support

TED provides video downloads for their talks. Not all of these are available with subtitles and when they are the subtitles are burnt into the video. Now with this new FFmpeg feature you can download the subtitle files and just display them on the fly when playing the video with ffplay:

    ffplay ted.mp4 -vf subtitles=ted.json
  

- geq filter ported from libmpcodecs

This is another filter ported from MPlayer. It allows you to arbitrarily change luma and chroma values for each pixel of the movie individually. To learn more look at the geq documentation and the evaluation syntax description. Do not forget to give it a try:

    ffplay input.movie -vf "geq=p(X\,Y):if(gt(Y\,H/2)\,128)+ifnot(gt(Y\,H/2)\,cr(X\,Y)):if(gt(Y\,H/2)\,128)+ifnot(gt(Y\,H/2)\,cb(X\,Y))"
  

- filter for loudness analysis following EBU R128

This filter analyses audio streams as recommended by EBU recommendation R128. The output can be either logged or visualized in a generated video stream.

- FFM2 support

The FFM2 format has been introduced to provide better interoperability between different versions of the FFmpeg tools. It is usually used to provide input to ffserver. It improves on its predecessor FFM by making the format backward-compatible and extensible. This means the generated files are are no longer dependant on specific FFmpeg versions.

- Opus encoder using libopus

You can encode Opus now via Xiph's libopus.

- VobSub demuxer

IDX/SUB file pairs can now be played back or be remuxed into other formats such as MKV.

- Resolution & pixel format change support with multithreading for H.264

Finally H.264 with resolution and/or pixel format changes can be decoded multithreaded.

- documentation split into per-component manuals

In an on-going effort, the documentation is split, reordered and extended to make it more accessible and more complete.

Of course we can't possibly cover all changes since our last release in a single news article, but we encourage you to read the Changelog yourself.

We wish you all a happy new year!

FFmpeg is moving faster than ever before, and with your help we could move even faster. If you know C and git and want to maintain some part of FFmpeg you can help us. Clone git://source.ffmpeg.org/ffmpeg.git, pick an area of the codebase you want to maintain, subscribe to ffmpeg-devel and start hacking on the code you are interested in, review patches on the mailing list, and fix bugs from our bug tracker that are related to the area you want to maintain. Once you are happy with your work just send us a link to your public git clone (for example from Github). Non-programmers are welcome to contribute too. We are also searching for someone to make new official Debian and Ubuntu packages, that would be part of the official distributions. If you have questions, just ask on ffmpeg-devel mailing list or our IRC channel #ffmpeg-devel.

We recommend distributors and system integrators whenever possible to upgrade to 0.7.7, 0.8.6 or git master. But when this is not possible 0.5.5 is more secure than previous releases from the 0.5 branch. If you are looking for an updated 0.6 release, please consider 0.7.7 which is ABI compatible and contains a huge number of security fixes that are missing in 0.6.*.

November 4, 2011

Instead of having fun outside in the warm summer months, we have made a new release: FFmpeg 0.8! All bugfixes and merges from ffmpeg-mt and libav are included in this release. Although we still recommend you use the latest git version of our code.

We have also made an OLDABI release: FFmpeg 0.7.1. It contains almost all of the features, bugfixes and merges of ffmpeg-mt and libav of 0.8, while being compatible with the 0.6 ABI and API. It has a few missing features, read the Changelog for more information.

May 3, 2011

FFmpeg now accesses x264 presets via libx264. This extends functionality by introducing several new libx264 options including -preset, -tune, and -profile. You can read more detailed information about these options with "x264 --fullhelp".

The syntax has changed so be sure to update your commands. Example:

ffmpeg -i input -vcodec libx264 -preset fast -tune film -profile main -crf 22 -threads 0 output

April 27, 2011

FFmpeg now has an oldabi branch. It is updated to master but with the old ABI. Only fixes that break the old ABI are missing from this branch.

To access the oldabi branch, clone FFmpeg, then do

git checkout oldabi

To get back to latest FFmpeg, just run:

git checkout master

April 14, 2011

FFmpeg can now decode 9-bit and 10-bit H.264 streams, used in particular by AVCIntra 50.

April 4, 2011

In order to supply our release users with the newest features and bug fixes we are in the process of making a new release. The release will be based on the latest development tree while staying API/ABI compatible to the previous release.

Please download the release candidate and report problems to our bug tracker.

March 30, 2011

Win32 and Win64 builds of FFmpeg are now available at http://ffmpeg.zeranoe.com/builds/

Please report any bugs to our bug tracker.

Today FFmpeg-mt, the multithreaded decoding branch, has been merged into FFmpeg. This has been a long awaited merge, and we would like to thank Alexander Strange for his patience and hard work.

Testing is appreciated and if you find any bugs please report them to our bug tracker.

March 21, 2011

The mailing lists have been fully migrated to ffmpeg.org!

The FFmpeg mailing lists were moved from sourceforge.net to mplayerhq.hu in April 2005, and moved from mplayerhq.hu to ffmpeg.org in 2011.

Unfortunately the lists were down for a few hours because of the abrupt shut down on the previous server[1]. We apologize for this interruption. Also we could not move the subscribers of the libav-user mailing list (libav-user is for application developers using libav* libraries from the FFmpeg project). Even though libav-user was not listed in the shut down announcement[1], it was also shut down.

If you are not yet subscribed we encourage you to do so now if you are interested in FFmpeg or multimedia or both. Visit our contacts page to find out more about the various mailing lists surrounding the FFmpeg project. You can also find the archives there if you like to browse the old posts.

As stated in the previous news entry we are in the process of recovering our project infrastructure. We will keep you posted.

Reinhard Tartler backported several security fixes to the 0.5 release branch and made another point release, that is 0.5.4. Note, 0.5 is quite old and this release is mostly for those stuck with the 0.5 branch, and not so interesting for end users.

    Changelog between 0.5.3 and 0.5.4

- Fix memory corruption in WMV parsing (addresses CVE-2010-3908)
- Fix heap corruption crashes (addresses CVE-2011-0722)
- Fix crashes in Vorbis decoding found by zzuf (addresses CVE-2010-4704)
- Fix another crash in Vorbis decoding (addresses CVE-2011-0480, Chrome issue 68115)
- Fix invalid reads in VC-1 decoding (related to CVE-2011-0723)
- Do not attempt to decode APE file with no frames

FFmpeg has been forked by some developers after their attempted takeover[1] two months ago did not fully succeed. During these two months their repository was listed here as main FFmpeg repository. We corrected this now and list the actual main repository and theirs directly below. All improvements of their fork have been merged into the main repository already.

Sadly we lost a not so minor part of our infrastructure to the forking side. We are still in the process of recovering, but web, git and issue tracker are already replaced.

Readers who want to find out more about the recent happenings are encouraged to read through the archives of the FFmpeg development mailing list[2]. There was also a bit of coverage on some news sites like here [3].

FFmpeg development has moved to Git, and the SVN repository is no longer updated. The SVN repository may be removed in a near future, so you're recommended to use a Git repository instead.

The last revision committed to SVN was r26402 on 2011-01-19 and replaced the svn:external libswscale with a standalone copy.

Oct 18, 2010

We have just pushed the first point release from our 0.6 release branch: FFmpeg 0.6.1. This is a maintenance-only release that addresses a small number of bugs and security issues. It also adds a newer version of the AAC decoder, which enables the playback of HE-AAC v2 media.

We have also taken the time make another point release our 0.5 branch: FFmpeg 0.5.3. It is a maintenance-only release that addresses a security issue and a minor set of bugs.

Distributors and system integrators are encouraged to update and share their patches against our release branches.

June 15, 2010

A bit longer than actually expected, but finally, we are proud to announce a new release: FFmpeg 0.6. Check out the release notes and changelog.

It is codenamed "Works with HTML5" as the special focus of this release were improvements for the new multimedia elements in HTML5. The H.264 and Theora decoders are now significantly faster and the Vorbis decoder has seen important updates. This release supports Google's newly released libvpx library for the VP8 codec and the Matroska demuxer was extended to support to WebM container.

This release includes again an extensive number of changes; some of its highlights are:

• Significant work to support at least decoding of all widespread mainstream proprietary codecs, and as usual broad coverage of widespread non-proprietary codecs, such as:
  • decoders and encoders
    • VP8 (via Google's libvpx library)
  • decoders
    • AMR-NB
    • Atrac1
    • HE-AAC v1
    • Bink
    • Bluray (PGS) subtitle
    • MPEG-4 Audio Lossless Coding (ALS)
    • WMA Pro
    • WMA Voice
• Highlights among the newly supported container formats:
  • demuxers and muxers
    • Adobe Filmstrip
    • SoX native format
    • WebM support in Matroska de/muxer
  • demuxers
    • Bink
    • Core Audio Format
    • Dirac in Ogg
    • IV8
    • QCP
    • VQF
    • Wave64
  • muxers
    • IEC-61937
    • RTSP
• faster AAC decoding
• faster H.264 decoding
• numerous ARM optimizations
• important updates to the Vorbis decoder
• RTP packetization support for H.263, and AMR
• RTP depacketization support for AMR, ASF, H.263, Theora and Vorbis
• RTMP/RTMPT/RTMPS/RTMPE/RTMPTE protocol support via librtmp
• the new ffprobe tool
• VorbisComment writing for FLAC, Ogg FLAC and Ogg Speex files
• and so much more!

June 2, 2010

We are pleased to announce that FFmpeg will be present at LinuxTag in Berlin June 9-12 where we will be showing some spectacular demos. There will also be some trolls.

May 25, 2010

We have just pushed out another point release from our 0.5 release branch: FFmpeg 0.5.2. This is a maintenance-only release that addresses a small number of security and portability issues. Distributors and system integrators are encouraged to update and share their patches against this branch.

March 19, 2010

Once again, FFmpeg has been accepted to take part in the Google Summer of Code. Here is the Google SoC FFmpeg page.

We have a list of proposed project ideas available so, if you think you might be interested, head over there to see if there is any project on which you wish to work and for which you may wish to make an application. The list is still in flux, and you're free to come up with your own ideas, but note that proposals should be closely tied to the progression of FFmpeg's code base.

We would like prospective students to show us that they've got what it takes to be a contributor to FFmpeg. If you think you're suited, then please complete a small task before submitting your Summer-of-Code proposal. Note that many of the proposed Summer-of-Code projects have specific tasks that you would want to work on, since they would show us that you're comfortable in that particular piece of our codebase that relates to your specific project. Send patches to the mailing list for review, so that you will learn about our patch review process, inline replying (because we don't like top-posting on our mailing lists) and general interactions with our developer base.

The sooner you start communicating with us and working within our code base, the sooner both you and we will ascertain your suitability and you will get used to our development methodology. You have until the application deadline to complete your small task. Good luck!

March 2, 2010

We have just pushed out a point release from our 0.5 release branch: FFmpeg 0.5.1. This release fixes security, packaging and licensing issues for FFmpeg 0.5, but it is a maintenance only release; no new codecs, formats or other feature are being introduced. The full details are spelled out in the the release notes and changelog.

There have been security fixes for the ASF, Ogg and MOV/MP4 demuxers as well as the FFv1, H.264, HuffYUV, MLP, MPEG audio and Snow decoders. libswscale can now be compiled in LGPL mode, albeit with x86 optimizations disabled. Some non-free bits in a test program were replaced. The AC-3 decoder is now completely LGPL. AMR-NB/WB support is now possible in free software through the OpenCORE libraries.

To help packagers, the x264 glue code was updated to work with newer versions and symbol versioning was backported, as was the lock management API. The symbol versioning change is enabled on platforms that support it. This allows users to upgrade from 0.5.1 to the upcoming 0.6 release without having to recompile their applications. While this release is both API and ABI compatible with 0.5, please note that distributors have to recompile applications against 0.5.1 in order to make seamless upgrades to 0.6 possible.

March 1, 2010

We have been busy over the past few months. Among other things, the results are an Indeo 5 video decoder as well as audio decoders for AMR-NB, Sipro, MPEG-4 ALS and WMA Voice, complete support for Bink, CDG and IFF PBM/ILBM bitmaps, an RTSP muxer, Bluray (PGS) subtitle support, a protocol for file concatenation and the ffprobe tool for extracting information from multimedia files.

September 23, 2009

In 1992 Sony introduced the first Minidisc player. 17 years later it is now possible to transfer and play back the raw ATRAC data from the actual digital disc with the help of FFmpeg, tools developed by the Linux Minidisc project and official hardware (MZ-RH1). So if you have lots of digital recordings stored on Minidisc now is the time to archive it all.

One of the last entrenchments of proprietary multimedia has fallen: Windows Media Audio Pro support is finally available in FFmpeg. It decodes all known samples flawlessly and is considerably faster than the binary decoder from Microsoft. A big thank you goes out to all the reverse engineers and programmers who made this possible. It really was a herculean effort.

August 24, 2009

Just a very short time after its launch (~10 years), FFmpeg now supports decoding of TwinVQ (remember .vqf files?). Now FOSS enthusiasts can finally contribute to the late 90's discussion if it sounds better than MP3 or not.

July 24, 2009

FFmpeg has removed support for libamr as of svn revision 19365. It has been replaced with support for libopencore-amr. Naturally the configure options have changed. The libamr options have been removed and there are two new options to take their place:

• --enable-libopencore-amrnb
• --enable-libopencore-amrwb

The reason for this change is that the libamr license was non-free, while libopencore-amr is licensed under an Apache 2 license. The change was discussed at length on the developer mailing list during May, June, and July. This has several effects:

• You may now distribute FFmpeg builds with support for dynamically loading libopencore-amr
• Support for AMR-WB encoding has been removed since libopencore-amr does not support it

May 7, 2009

Google are again running their Summer of Code program and, as usual, we will be applying for a project position. As such we will need strong project proposals and qualification tasks for the students to complete.

To all the students out there who want to work on FFmpeg over the summer, the sooner you begin to contribute to the project the better. Working on digital multimedia software is not the easiest task and getting code into FFmpeg's trunk repository demands significant rigor and commitment.

Until we are officially accepted into the program, you could take a look at the list of small tasks we have and try to complete one of those. Support for development of FFmpeg is available via the FFmpeg-devel mailing list or IRC.

December 20, 2008

RealVideo 3.0 decoder added. Still working the bugs out, please test and report any problems.

The FFmpeg project would like to recognize and thank the people at Picsearch for their help improving FFmpeg recently. The Picsearch team makes extensive use of FFmpeg and provided feedback to FFmpeg in the form of thousands of files that either crash FFmpeg or use unsupported/unknown codecs. The FFmpeg development team is putting this information to work in order to improve FFmpeg for everyone.

We know that there are other organizations using FFmpeg on a large scale to process diverse input types. The FFmpeg team invites those organizations to provide similar feedback about problems encountered in the wild.

A bunch of new formats have recently been added to FFmpeg, namely a QCELP/PureVoice speech decoder, a floating point PCM decoder and encoder, a Nellymoser ASAO encoder, an Electronic Arts TGQ decoder, Speex decoding via libspeex, an MXF muxer, an ASS/SSA subtitle demuxer and muxer and our AC-3 decoder has been extended with E-AC-3 support. Last but not least we now have a decoder for RealVideo 4.0.

FFmpeg is undergoing major changes in its API/ABI. The last valid revision for libavcodec version 51 is r15261.

August 21, 2008

The AAC decoder from FFmpeg Summer of Code 2006 has finally been cleaned up and is now in FFmpeg trunk. It supports Main and Low Complexity profile AAC but does not yet support HE AAC v1 (LC + SBR) or v2 (LC + SBR + PS), though implementation of this support is underway. It is considerably faster than FAAD and you should expect further performance improvements and bug fixes in the coming weeks.

Also, FFmpeg now has floating point PCM support and supports MLP/TrueHD decoding (FFmpeg SoC 2008 should bring us an encoder), Apple Lossless Audio encoding (FFmpeg SoC 2008) MVI demuxing and Motion Pixels Video decoding, D-Cinema audio muxing, Electronic Arts CMV and TGV decoding and MAXIS EA XA demuxing/decoding.

UAB "DKD" (dkd.lt) have released a Nellymoser ASAO compatible decoder and encoder under the LGPL. This will aid the development of a native encoder in FFmpeg, and right now a GSoC student is working hard on just that task. A great thanks to UAB "DKD" for this contribution to the FFmpeg community.
