AviSynth: No Audio available for AVI-Files

[klischee]

Hi

I occur problems with AviSynth. When I try to open AVI-Files through AviSynth in VirtualDub, I get the following error message:

"Avisynth open failure:
FFAudioSource: Audio track contains no audio frames
(FFMS2.avsi, line 41)"

I am using following script code:

ffmpegsource2("D:\video.avi", atrack=1)

I tried it with a lot of AVI-Videos (mostly XviD or DivX, LameMP3) and I mostly (but now always) get the error. But with other formats like AVC/AAC it works with the code above. Any idea what I am doing wrong? Also atrack=-1 does not work.

Why don't you use AviSource() for AVI files? Check your source file with MediaInfo.

I checked all the files with MediaInfo. It makes no sense - the one video gets opened correctly, while the other with exactly the same encoding settings does not.

I would like to use ffmpegsource2 because I generate the .avs through a script and it would make a lot of of work to use for every single case other AviSynth Plugins...

Shouldn't it work with FFMS2?
