So I've built FFmpeg as mentioned by qyot27. Then I've built ffms2 (just did make install, as I don't have checkinstall). Even did all the stuff mentioned in the last message by Richard1485 (I only copied one file libfmms2.so, as nothing else I have is applicable I think).
On ffplay my avs script all I get is
[verbose] Initialized opengl renderer.
[NULL @ 0x7f4600000bc0] [debug] Opening 'film-test-linux.avs' for reading
[file @ 0x7f46000017c0] [debug] Setting default whitelist 'file,crypto,data'
[avisynth @ 0x7f4600000bc0] [debug] Format avisynth probed with size=2048 and score=50
[AVIOContext @ 0x7f4600009b80] [verbose] Statistics: 1680 bytes read, 0 seeks
[error] film-test-linux.avs: Unknown error occurred
- and exit (not a hang this time).
I get this even if I comment every single line of my avs script!!!
Btw, I am having vapoursynth trouble with libffms2.so in this thread:
