What steps will reproduce the problem? 1. Download http://www.mediafire.com/file/v9jp3ifvy3ytbxu/test.m2v 2. Attempt to read using FFVideoSource("test.m2v") What is the expected output? What do you see instead? Expected: file loads correctly
Observed: FFVideoSource: Can't open 'test.m2v' What version of the product are you using? On what operating system? v2.14 on Windows 7 64-bit with 32-bit Avisynth 2.58
v2.14 on 64-bit Linux using 32-bit wine and 32-bit Avisynth 2.58 Please provide any additional information below. I have a script that demux's program chains from DVD menus and converts any short video sequences to PNGs. It uses FFVideoSource in the workflow. Many DVD menu program chains have a duration of 1 frame.

I've just upgraded to v2.14 and find some m2v files can no longer be opened by FFVideoSource.

Here's an example m2v file where it fails: http://www.mediafire.com/file/v9jp3ifvy3ytbxu/test.m2v The error I see with v2.14 is:
FFVideoSource: Can't open 'test.m2v'

As far as I can tell there is nothing wrong with the m2v file, I can 'play' it ok in ZoomPlayer, MPC-HC and VLC.

v2.13 has the same problem. v2.12 works correctly.

It seems to be a bug in ffmpeg; av_open_input_file refuses to open the file. I guess I'll go harass them about it.

A patch suggestion was prepared 6 months ago by the FFmpeg developers. Then it died. Don't expect this to be fixed.

Well, we can't fix this ourselves, so harass the ffmpeg people if you want it fixed. Closing.
