avisynth could not decompress frame 0

[adrianmak]

I have a video encoded in h264 with mp3 audio stream and in avi container.
VDM 1.5.10.2 can open the video directly without any problem. But when VDM opened the video thru avs script , it produced "could not decompress frame 0" error

this is my script
Loadplugin("vsfilter.dll")
AviSource("myvideo.avi")
return textsub("01.ass").textsub("staff.ssa")

1) Which decoder is used to decode your avi (when opening it in VDM -> file properties)?

2) DirectShowSource and ffdshow will be able to open it.

edit: i deleted your other duplicate post, since it was an old thread anyway.
