The bug

I just found out that videos of a specific vacation can't be played anywhere, even if I have "transcode videos not in desired format" enabled.

I found out that the video codec is h264, but the audio codec is "twos". Immich didn't respect that and thus didn't transcode it.

I looked into the code and I suspect that ffprobe is crashing by trying to look up the audio codec. I started the "transcode missing" job again and there were some erros in the logs like:
