Video - Could not find tag for codec wavpack in stream #1, codec not currently supported in container Could not write file MKV to MP4 with FFmpeg

Question

Trying to convert an hour long MKV file into an MP4 using FFmpeg , but during the conversion process it keeps giving me this error:

Could not find tag for codec wavpack in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

I have tried to use other converters, but they all have file size limits, It takes to long to convert with Handbrake and VLC . I tried to search for some kind of answer on google, but there has been no forum posts anywhere for a solution to this kind of issue.

Answer 1

The error is your answer. Wavpack is not supported in mp4. So you muse use a container where it is supported (mkv) or convert it. You cna probablly convert just the ausio however and keep the video.

eg ffmpeg -i my.mkv -vcodec copy -acodec aac my.mp4
