Decoding error when trimming with avisynth

Post by Alex-Kid » Wed Mar 30, 2011 2:02 am

Hi admin,

I was doing some highlights for a match I captured (preparing myself for Copa America ;) ), using avisynth and DGAVCDecDI, of course. On trimming (I did many trims), I noticed that, in several cases, the first frames of a trim were incorrectly displayed, like this

then the next ones were correctly displayed. But if I step forward from frames before that trim, those incorrectly displayed frames turned correct. So it means there's no corruption on those frames.

I use DGAVCDecDI 2038, VirtualDub 1.9.9 and avisynth 2.58 tsp MT version 5(mod seraphy) build: apr 5 2009.

Recreation:
1. Use this file (http://www.mediafire.com/?l3x22k9lvbr6rk2) as source (HD stream).
2. Load the script on VirtualDub.
3. Go to frame (Ctrl+G) 624, it should have the issue.
4. Stepping forward until frame 640 should have the issue too. From 641 is OK.

Is there any way to fix this issue? I think it's related to MBAFF.

I hope to be clear. Saludos.

PS: if you want the audio to be played, it's in LATM container. More info about conversion to ADTS, here → http://forum.???.org/showthread.php?p ... ost1453484

Not yet, but it's at the top of my list.
