XviD/Divx seek problems

[unknownsoldierx]

It used to be that jumping to a position in a WMV file would cause the video to be garbled for 5-10 seconds. VLC 0.9.2 no longer does this with WMV. Now it does it with XviD/Divx files, which I have never seen before.

From my experience it's doing it with DivX / XviD videos which have been encoded in Packet Bitstream mode.

Is there any way to tell from the files? I don't remember if that was enabled when they were encoded.

There is some others topic on this issue but i didn't really read them completely.

It's true it was quite acceptable when it was for wmv and some mpeg IIRC, cause it's not most codecs/container used nowadays, but for Xvids yeah it's quite annoying

GSpot or Mediainfo or similar tools should tell about packet bitstream. You can easily remove packet bitstream with tool called MPEG4 Modifier. If it helps, shout it back here, so Lotesdelere, I or someone else can double confirm this to trac ticket.

True. Also in 0.9.4.

It's really annoying. I've to use WMP. This problem does NOT exist with version 0.8.6. Why?

[VLC_help]

Because the issue comes from AVcode (FFmpeg). And it was updated for 0.9.x release because it includes better codec support and some other fixes.

Is this issue going to be fixed in the next release?

It is up to ffmpeg devs if this gets fixed.

[unknownsoldierx]

I meant to report back sooner, but I've been away.

I have videos that mpeg4modifier says do not have packet bitstream, and they still have the problem when played in VLC. I guess we should report these issues to the ffmpeg devs and get on them to fix it.
