If your GOPs are long then a large section of video can be destroyed by a short glitch.

i have "bad" sample http://www.mediafire.com/?y4tej0guuns

it indexes ok, but then i load avs in virtualdub, virtualdub stops responding and after 20-25 seconds virtualdub shows green frame, then i go forward frame by frame, i see correct picture at frame 7. and from frame 7 i step backwards and some frames that were previously green, now they correct.

sorry for bad english

EDIT:
ffdshow don't understand this sample too...

Yes, you do. The transport stream is corrupted. I can't help you with that.

Can you compile DGAVCDec with this patch to support H.264 predictive lossless?

If it won't apply to the older version of libavcodec I use, then I can't absorb it. I'm not able to update libavcodec, due to several critical regressions for frame accurate seeking that the developers consider low priority (which in practice means do it yourself or forget it). Unfortunately I have too much of my own work to get involved in libavcodec development.

The stream contains no IDRs. You'll have to enable Treat I as IDR and accept that the first few frames will be trash.

Is that from the Hauppauge HD-PVR? If so, you can use the Graphedit hack to enable IDRs.

its recorded from DVB-T with DVBViewer. i enabled Treat I as IDR options, but still it takes long time to open, for sample (10mb) ~23 seconds, and whole recordind (700mb) virtualdub stops responding but uses ~90% CPU and i waiting like 10 minutes now

OK, I'm looking again to see why the open is taking so long.

I've found and fixed the problem. Actually, your stream has RPS's so it should be fine. There was a bug in my handling of open GOPs.

Preparing a new release...

Version 1.0.7

* Fixed a bug in handling of open GOPs that caused problems when the first GOP of the stream is open.

Correct. It's not open source. But see below.

I use libavcodec as a DLL. The change you seek would be made there. Refer to the file libavcodec.txt in my distribution for details. I advise you not to bother trying to upgrade to the latest ffmpeg code as it is broken for random access. You can certainly try to patch the version I am using, but I don't know if the patches will cleanly apply to that older version.

Investigating...

Thanks. I've needed such a clear demonstration for some time. It plays in sync in VLC.
