[FFmpeg-devel] [PATCH]Fix compilation with --disable-filter=buffer

[Carl Eugen Hoyos]

Hi!

A few unusual configure options lead to a link failure with ffmpeg_g:
LD      ffmpeg_g
ffmpeg.o: In function `output_packet':
ffmpeg.c:1657: undefined reference to `av_vsrc_buffer_add_frame'

Please comment, Carl Eugen
