🐞 Could not find tag for codec pcm_alaw in stream #1

I get this error:

Hello @helmutcarter 🙋
What does media-info print out for both files?

ffmpeg's binary updated at some point and now they don't support pcm_alaw. You need to pick a different audio codec like AAC or FLAC or something.

I had an old version of ffmpeg (not sure which one, unfortunately), and updated to the latest build yesterday. A test video I was converting from .avi to .mp4 (-copy c:v -copy a:v) worked before, and throws the same error as you now with the new version. Other content online seems to corroborate this https://stackoverflow.com/questions/47495713/could-not-find-tag-for-codec-pcm-alaw-in-stream-1-codec-not-currently-supporte

Hey @Tyler-H 👋
Thank you very much for your post! Very interesting 😊
Will take a closer look into this, would be cool if this could be reproduced with youtube-dl somehow 🤠

Same issue...
Could we record using different container? MKV for example?
