Default Bug in mp4 audio loader that produces audiable glitch



Note that the audio that is show when zoomed out some is actually heard. It is not a video issue. Seems to happen with mp4's but not wavs.

There is no glitch in the actual audio. Viewing in something like Adobe Audition doesn't show the glitch, nor is it heard. Seems to be a reaper issue. Works fine with VLC too.

This is a very consistent problem, happens on almost all mp4's. It seems wrap the tale end of the file to the start. Some type of offset bug

That is, if the file ends abruptly then part of that last 1/10 of a second gets wrapped to the start of playback. This means that audio that fades out to nothing before it ends won't have the issue. Hence, chop a mp4 up in the middle then import that and check.


Works fine with ffplay so this suggests a reaper issue or the reaper ffmpeg version. Probably a reaper issue.
