[FFmpeg-devel] [PATCH] avformat/avisynth: Don't insert null frames or samples at the start of a stream.

This is the last remaining issue from ticket #2412, and also seems
to resolve another issue relating to sluggish start performance for
certain source filters when using a combination of certain fps
rates and the SSRC filter. In FFMS2's case, it could actually
cause ffmpeg.exe to hang and/or segfault.
