2c25e83b1d
Uses the 2.5 compatibility header included with the variant of FFMS2 that uses AviSynth's C-interface. A copy of this header is now provided in compat/avisynth. avs_get_row_size_p and avs_get_height_p changed between versions 2.5 and 2.6. Since the avisynth_c.h header that avformat uses assumes AviSynth 2.6, it would cause 2.5 to crash if given any kind of real video (the Version() function was known to work, though). AvxSynth was unaffected by this issue because, despite being based on AviSynth 2.5.8 and using 2.5.8's interface version number of 3, it actually uses 2.6's versions of these functions.
