Hi,
We are using 'ffmpeg version 2.8.11' library for one of our medical application
running on Cent OS (linux) to convert audio/video streams.
We want to migrate to latest ffmpeg version 4.2 on RHEL8 linux platform.
Kindly let us know what are major differences in ffmpeg ver 4.2 and 2.8.11
Thanks

Please check the informations available on the homepage:

You should post such questions on the FFmpeg user mailing list,
not the developer's one.
Hope this helps! Reto

That's unrelated to this patch. I can look into reverting 976dae8b32 and
preventing data copying when the frame doesn't change in a separate
patchset.

and have it coexist with FFMPEG_DECODER. Assuming it's needed.

Right now, the concat filter does not set the frame_rate value on any of
the out links. As a result, the default ffmpeg behaviour kicks in - to
copy the framerate from the first input to the outputs.
If a later input is higher framerate, this results in dropped frames; if
a later input is lower fr

Some decoders may not need a writable buffer in some specific cases, but only
a reference to the existing buffer with updated frame properties instead, for
the purpose of returning duplicate frames.
