What steps will reproduce the problem? 1. A m2ts Blu-ray source. 2.AVS: o = FFMpegSource2("00054.m2ts",atrack=-2) return o

  1. No problem with the indexing.
  2. Encode the file using VirtualDub with ffdshow ffv1 codec, fast recompress mode. What is the expected output? What do you see instead? A long movie with more than 160000 frames. Vdub crash at randomly frame 5800-7300 aprox. This is the error:

Well stopped reading at 1. Read: http://forum.doom9.org/showthread.php?p=1507010#post1507010 Upload a sample that fails and I'll take a look at it anyway but it's probably just the same old same old with BD.

It still shouldn't outright crash. Provide sample.

Mmmm, it's progressive. I'll upload a sample, what is the best program to cut m2ts? it's huge, 500mb would be enough?

DGSplit will be more than good enough in this case, and you need a sample big enough that it triggers the crash. I leave it up to you to figure out how much that is.

Also: does it still crash if you use ffindex("00054.m2ts",demuxer="lavf") first? Note that if you do this you should also set seekmode=-1 on the ffvideosource() call.

Seems that it works correctly with demuxer="lavf". Thanks a lot. Sorry for the inconvenience, I'm a noob working with BD and ffms2.

Still shouldn't crash with the default demuxer so a sample that reproduces that would be nice.

The sample: http://www.megaupload.com/?d=H9X41F37 http://www.megaupload.com/?d=KB6F9XX8 http://www.megaupload.com/?d=OM0136YB http://www.megaupload.com/?d=FA5ICMV3 It crash while encoding frame 6000-7000.
