Expected Behavior
MPV should play the sttream, VLC plays the stream fine.
Actual Behavior
See attached image
Log File
Sample Files
No response
I carefully read all instruction and confirm that I did the following:
- I tested and confirmed that the issue exists with the latest release version or newer.
- I provided all required information including system and mpv version.
- I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of
--log-file=output.txt. - I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
- I attached the full, untruncated log file.
- I attached the backtrace in the case of a crash.

Research direction
Start by reproducing the direct mpv command against the listed RTP stream, using the reported mpv, macOS, and FFmpeg versions. Compare its behavior with the working ffmpeg-piped path and use the decoder and demuxer errors to identify the relevant playback path; done means the stream plays directly in mpv without the reported corruption and decoding failures.
