FFMPEG: No video codec found (3.0.0)

Hi Darby! Just tried your new release and I'm facing an FFMPEG issue with a sample video:

I did notice:

NOTE: Download packages only include a minimal set of video codecs. To enable full support for video codecs, either compile from source or replace the FFmpeg shared library files.

However, mp4/mpeg4 seems enabled.

Have you seen this before?

[darbyjohnston]

Hi, and thanks for trying out the new version. The mp4 codec is not included with the download packages for legal reasons, I think what you are seeing is just support for the "container" format. I think other codecs like AV1 can also be embedded in mp4 files.

[aberkl]

replace the FFmpeg shared library files.

@darbyjohnston Can you give a more detailed hint on how to do this?
Also, which video codecs are supported "out of the box"?

[darbyjohnston]

I would recommend building from source instead of trying to replace the shared libraries; replacing the libraries is technically possible, but tricky to get right.

You can see the full list in the logs, but I believe the download packages have MJPEG, MP3, WAV, and a few Apple uncompressed video formats. Building from source will enable MP4, ProRes, and all the other codecs.

[michimussato]

Compiling from source with

cmake --build Release -j 1 --config Release

threw the following error:

CMake Error at CMakeLists.txt:113 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

(log.txt)

My cmake:

$ cmake --version
cmake version 4.0.3-dirty

I'm not familiar with cmake and exporting export CMAKE_POLICY_VERSION_MINIMUM=3.5 just threw an error somewhere else down the line.

Sorry for the hassle.

[darbyjohnston]

No problem, thanks for trying the build. I think the problem may be the new 4.x version of CMake, I have only tested with the 3.x versions.

[NTKKS]

Couldn’t we just set path to our existing ffmpeg? I never compiled/built any software.

[aberkl]

Couldn’t we just set path to our existing ffmpeg?

Sounds like a good idea.

I never compiled/built any software.

Same here ;-)

[darbyjohnston]

The older version won't work, FFmpeg needs to be compiled with the exact settings as the new version of DJV.

Hopefully DJV will start to get picked up by package managers that may provide the option to use the full FFmpeg.

Also at some point I hope to enable the AV1, VP9, and OpenAPV codecs for movie playback, which will hopefully start replacing codecs that have potential legal issues.

[metehus]

same issue :(

[michimussato]

I still haven't tried with cmake3 but will do soon. Just a random thought though: if shipping a release with codecs enabled introduces legal issues whereas building it from source does not, where's the point? Could a user just be presented with a third party license agreement that has to be accepted for a fully featured DJV whereas if he doesn't, DJV would run with the current "limited" functionality?

[michimussato]

I just tried a build on Docker archlinux/archlinux:latest with cmake3 without success. What is your Linux build setup (what are the actual package requirements)? Do you happen to have a Dockerfile perhaps?

I don't have experience with Docker, but maybe that would be a good path to making it more easy to build. Currently all of the builds are done with GitHub actions, which uses Ubuntu for the Linux runners.

As far as the legal matters, I am not a lawyer, but as far as I understand the troubles come with distributing the built codecs. If you build from source it's OK to use personally, but not distribute.

Hi. Thanks for you work! I’m much better at clicking mice than building software, but being unable to inspect H264 video in latest release of DJV for MacOS (on 14 here), this thread led me to build it. Had to uninstall latest cmake installed by brew (build was bombing on it) and install 3.31 manually, but in the end: success.

Only I can’t open AV1-encoded videos. My ffmpeg (build by brew) says --enable-libdav1d --enable-libaom, but DJV says

9.62 tl::io::ffmpeg::ReadPlugin: Your platform doesn't support hardware accelerated AV1 decoding.
9.62 tl::io::ffmpeg::ReadPlugin: Failed to get pixel format.
9.62 tl::io::ffmpeg::ReadPlugin: Get current frame error

Anything I should do to my brewed ffmpeg before building DJV? Or, maybe, I should do something during the DJV build? Sorry for newbie questions and thanks again!

@paperboyo Nice work! I'm not sure about the error message, I would need to look into it. Hopefully when the next version of FFmpeg is available in a couple of weeks I can enable AV1 by default.
