Hi All,

As per your valuable suggestion, I updated the ffmpeg version to the latest one, i.e., version 4.2.2 and used the following command to transcode the respective .mov file to .mp4 file.

ffmpeg -i Input0.mov -y -fpre ./preset/mp4_Projector.ffpreset -astrict -2 -vsync vfr -acodec copy -s 1280x720 Output0.mp4

‚ÄčThe above command was working perfectly till date in the code but all of a sudden this command didn't work for a particular .mov file and gave the following error:-

Too many packets buffered for output stream 0:1

The preset file that has been used, i.e., 'mp4_Projector.ffpreset' file's details is as follows:-


The respective .mov file is not corrupted as it was playing with QuickTime player. The above command was giving correct transcoded .mp4 video file so far. Can't understand why this same command failed for a particular .mov file.

Requesting assistance to resolve this issue.

Thanks & Regards

What is the application and have you contacted it's vendor/developers? There
may be an update.

That's a _very_ old version of ffmpeg and not supported here. First thing is
to get a new one, preferable last night's nightly build and try the same
command and input file (start from https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Fffmpeg.org%2Fdownload.html&data=01%7C01%7Crakesh.chakraborty%40mheducation.com%7C7bb045a80aba4ae47d5e08d7eac1c5b6%7Cf919b1efc0c347358fca0928ec39d8d5%7C0&sdata=tcW%2FV2N93KniCpBkyl4GXWMCWecSSuBVqa8MmSx%2BrGY%3D&reserved=0). If
that fails, then post the output here. Since it's using videolan's x264
software, that ought to be updated, too.

Do the .mov files play correctly with quicktime or vlc? (we don't know if
they're corrupt or not.)
