Comment (by bazz):

 Regarding the patch, I have tried it with an old commit ~Dec 2014 and also
 with the latest master branch on the FFmpeg github. I seem to get the same
 results on both versions.

 The FFMPEG PMF samples appear to play fine. But, I have my own samples
 that do not *fully* play with the patch. However, if you watch my PMF file
 on an unpatched version of ffplay, you can see the full video (without
 audio of course), so there is some issue in the ATRAC3P "process" (for
 lack of better words) that is causing ffplay to lock up.

 See for yourself!

 Running ffplay with `-v debug` did not reveal any hints as far as I could

 I don't know much about ATRAC3(P) so I hope this helps someone move
 further in solving this issue. I for one, will try to add further debug
 printouts to the ATRAC3P code to maybe provide a hint.

 Lastly, thank you to the patch author for getting us this far!

 I understand this patch is rather old, but I'm glad it still works
 (somewhat) and I hope we can move this further along.
