[FFmpeg-devel] [PATCH] Fix broken vbv_buffer_init handling in libx264.c

[Jason Garrett-Glaser]

Due to being pants-on-head retarded, libavcodec defaults this to zero, which
results in broken output.  This didn't affect ffmpeg.c, which sets it itself,
but caused problems for other calling apps using VBV.
