I would like to decode the mov file using ffmpeg in CentOS7 and convert it to mp4 file.
I entered the following command, but an error occurred and I cannot execute it.
I don't know how to deal with it.Do I have to add something to the ffmpeg build option?
Please let me know if you know.

You can now use the .
ffmpeg mov
ffmpeg-itest.mov-vcodec copy-acodec copy out.mp4
The above command specifies "simple copy of the video codec" and "simple copy of the audio codec" extracted from the input file (MOV format) and multiplexed into the output file (MP4 format).

[mp4@0x902a40] Could not find tag for codec processes in stream #0, codec not currently supported in container
As the above message indicates, the MP4 media container format specified in the output does not support the video codec prores (Apple ProRes422 Proxy).
If you simply want to convert to MP4 format, I think the following command is sufficient.In this case, the preres video codec is decoded once and automatically encoded by the H.264 video codec.
ffmpeg-itest.mov out.mp4
