If this is not the right place to report libavcodec decoding issues (my libavcodec VP6F decoding bug report didn't get many replies ^^), please let me know where I should do it. |
This one FFmpeg handles ok, so it is not an issue in libavcodec itself. The problem here is that the AVI claims 25 fps, but the MPEG-4 headers say 30 fps.
For the VP6F one, the AVI says the height is 416 pixels, however the correct value is maybe 408 or something like that. There is no "extradata" that would indicate the need for cropping either. Are you sure that this information didn't get lost at some point so what ffdshow decodes is simply the best it can do with the information in the file?
