Author: Martin Storsjö <[email protected]> Committer: Martin Storsjö <[email protected]> Date: Wed Jan 9 14:25:59 2013 +0200 rtpdec_vp8: Don't trim too much data from broken frames Previously, for broken frames, we only returned the first partition of the frame (we would append all the received packets to the packet buffer, then set pkt->size to the size of the first partition, since the rest of the frame could have lost data inbetween) - now instead return the full buffered data we have, but don't append anything more to the buffer after the lost packet discontinuity. Decoding the truncated packet should hopefully get better quality than trimming out everything after the first partition.
