[FFmpeg-devel] [PATCH 2/4] escape130: The minimum read in and after decode_skip_count() is 4 bits. Thus we can check for 4 being available. If the next block is skiped we need 4 bits to encode the skip. If the next block is not skiped then we need 1 bit for the skip code and at least 3 bits for the block.
