What steps will reproduce the problem? 1. Extract the h264 stream from a m2ts Blu-ray source to an mkv file.
2. Create AVS: "ffvideosource("shikiextra01.mkv",fpsnum=24000,fpsden=1001)"
3a. Encode the file using avs2yuv. A few frames to the end avs2yuv crashes, and x264 countinues with the remaining frames extremely quickly until it finishes.
3b. Encode the file using VirtualDub with codec Huffyuv. A few frames to the end VirtualDub crashes. What is the expected output? What do you see instead? I expected an output of 3251 frames, and I get one of 3247 frames. What version of the product are you using? On what operating system? Using ffms2 2.15-mt in Windows Vista x64. With ffms2 2.14-mt the problem don't occur. Please provide any additional information below. If I try to open the corrupted Huffyuv AVI file with vdub, I get these warnings:
[!] AVI: Index not found or damaged -- reconstructing via file scan.
[!] AVI: Invalid chunk detected at 1199713928. Enabling aggressive recovery mode.
[!] AVI: Keyframe flag reconstruction was not specified in open options and the video stream is not a known keyframe-only type. Seeking in the video stream may be extremely slow.
