Description

I have 3 sample files of the same source.

MP4.mp4 - This file has video lag/jump spikes and huge A/V Sync spikes.
MKV.mkv - Same files put into .MKV container. Has about 30ms A/V Sync issues, but no video lag spikes/jumps. By default, MKVmerge (mux to mkv tool) will assume 25 fps if not manually set).
MKV (Correct FPS Set).mkv - Same files put into .MKV container, but this time manually set the correct FPS of the video stream.

If the file was remuxed from .MP4 to .MKV (with correct FPS set in mkvmerge) it played fine on Showtime.

Both MP4.mp4 and "MKV (Correct FPS Set).mkv" played fine on the PC (VLC Player). MKV.mkv still had same sync issue on VLC Player as on Showtime.

So, try to fix compatibility with MP4.mp4 file. If possible, maybe also fix MKV.mkv (This is not very important, but maybe Showtime can manually detect video FPS and sync better, I don't know)...

I can't seem to notice any problems with the MP4 file at all?

Are you streaming from a network source or from local (USB, PS3 HDD?)

#3 Updated by Rusty Unknown over 9 years ago

I just redownloaded the MP4 sample from here and tested again, same result.

I still notice the A/V sync issue on the MP4.mp4 file.

I'm playing the file from PS3 HDD at file:///dev_hdd0/video/MP4.mp4

Maybe you did not play enough to see the full effect? Wait around 75% seek of the video and you will see it very easily. The Video will lag/jump/skip a few frames at a time it appears (this only happens at certain areas, but it is frequent).

If you open the "playback status" box (left joystick on PS3) look at the A/V Sync ms diff and you will notice some areas sync will almost be normal, then few seconds later it will jump 100 or 200+ (ms) sync diff. It is bad enough you can't enjoy the video.

I don't think it is important, but I am also playing it with the english audio track (I did not test the japanese audio track).

#5 Updated by Rusty Unknown over 9 years ago

I have attached an example screenshot of the A/V Diff as proof.

PS: There is only an eng track in this sample, so that is not the issue.

#6 Updated by Sasa Petrovic over 9 years ago

I have problem with some .mkv files. Until version 3.1.203 everything has been workin fine. With every next version there is no sound. Here is sample that I am using for testing

Sorry for posting here but I can't figure out how to add a new bug.

Hi,

Sorry but for me it's not Fixed, any of my *.mp4 are working.

#10 Updated by Valentin Meriel about 9 years ago

I post an example of a semi-none working file.

The first 2 or 3 seconds are displayed but it freeze after.

(it's not the same isue like Bug #842 because it's work on mkv)

#11 Updated by Andreas Smas about 9 years ago

Why do you attach the file to this ticket?

This ticket was about bad A/V sync and you seem to claim a file where video freezes.

#12 Updated by Valentin Meriel about 9 years ago

Sorry i didn't understood correctly.

I thought the probleme was the same.
