FFmpeg 4.x and 5.0 should work but any more recent versions may not. Especially the major versions (like 6 and 7) usually contain breaking changes and it looks like they now removed certain functions that were deprecated for a long time - I've seen deprecation warnings for this particular function with FFmpeg 5.

Answer 2 · 2024-05-06T12:45:02.000Z

Hi, untill ffmpeg 6.0 worked, but now with ffmpeg 7.0 not works anymore, thanks for your reply.
Someone can update the code to support ffmpeg 7.0?
Best regards.

Answer 3 · 2024-05-06T12:53:44.000Z

I guess FFmpeg 6 didn't break anything that Olive used then, but it hasn't been tested with this version and the automated builds use FFmpeg 5. There are no plans to update the current code base, therefore, please use an older FFmpeg version.

thanks @Simran-B ,
i have downloaded the source of ffmpeg 6.0, how can i pass it to olive?
can i add this line before the cmake?:
export PATH=/temp/buildCore/ffmpeg/build:$PATH
or i have to pass it in the cmake?
cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_RPATH=/temp/buildCore/ffmpeg/build

Thanks, best regards

Answer 5 · 2024-05-08T22:16:46.000Z

It should be sufficient to point CMake to the FFmpeg root folder like cmake .. -DFFMPEG_ROOT=/path/to/ffmpeg.
That folder should be one that is the result of compiling and installing FFmpeg (the libraries avutil, avcodec, etc.), not the raw source code.

Answer 6 · 2024-05-09T12:44:37.000Z

Hi @Simran-B ,
i did how you explain to me, but continue to find only ffmpeg of the system:

-- Found FFMPEG: /usr/include/x86_64-linux-gnu (found suitable version "7.0", minimum required is "3.0") found components: avutil

i have run this:
cmake .. -DFFMPEG_DIR=/app/ffmpeg/build

made in this way:

seems all ok, but not take FFmpeg i declare in cmake, why?
best regards

Answer 8 · 2024-05-09T21:03:45.000Z

The folder doesn't look correct. The FFmpeg root path is expected to contain an include directory or the CMake script will check other paths instead, like /usr/include. You seem to be pointing to the build directory, but you need to point to an install directory.

For example, when you configure FFmpeg, you can specify a prefix like ./configure --prefix="/app/ffmpeg/install" ....
Then you need to build FFmpeg with make and finally install it with make install. With the shown prefix, the files won't go to the normal system folders but to the specified path. You should then be able to specify the path like -DFFMPEG_ROOT=/app/ffmpeg/install. Accordingly, you should use export LD_LIBRARY_PATH=/app/ffmpeg/install/lib:$LD_LIBRARY_PATH.

You're a gentleman, thanks.
