Original commit message from CVS: * ext/ffmpeg/gstffmpegenc.c: (ffmpegenc_setup_working_buf), (gst_ffmpegenc_chain_video), (gst_ffmpegenc_flush_buffers), (gst_ffmpegenc_change_state): * ext/ffmpeg/gstffmpegenc.h: Instead of allocating 512KB buffers and then setting BUFFER_SIZE to what ffmpeg produced, we're better off by far to use a single working buffer and copy data out into neat little buffers. This prevents exhorbitant virtual memory wastage in the form of allocated but untouched buffers.
