mpegplayer A/V sync - please report experiences
Soader03:
Um, ok. I'll do an update and try a file. I'll edit this post for the uploaded video.
**EDIT**

Well done, the video is here, sorry if it's at Megaupload and it's slow...
Check the guy with the yellow t-shirt signing.
**REEDIT**
I just want to add that this video was synchronized before the synchronization update.
linuxstb:
Thanks for uploading that file.
It's not easy to tell what the correct a/v sync should be on that video, but comparing mpegplayer with "mplayer" (the video player I use for reference), there is definitely a large difference, so something is wrong with mpegplayer.
Before the AV sync commits, Rockbox would just play the video and audio at the correct speeds without taking into account the timestamps in the file. mpegplayer now attempts to play the video and audio according to those timestamps, which is where it must be going wrong in your file.
If you (or anyone else) have other videos with similar problems, they would be useful to have as well.

Yes, linuxstb described it as a requirement for this test and I think that it is obvious.
In addition the "Show FPS" option does not work on H120. Is it supposed to work on greyscale targets?
Llorean:
No, due to the way the grayscale library works it won't display.
Didro:
Have to say that before improvements my quality of video in MpegPlayer on IPOD nano was perfect and A/V sync works wonderfully. But after this it became worse, especially video. So please do feedback.
