Using -demuxer mpegts -correct-pts triggered the assertion in ds_get_packet2(). This is not surprising, because the correct-pts code was changed to accept _complete_ packets, while all the old demuxers (including the mpegts demuxer) require you to use "partial" packet reads, together with the video_read_frame(). (That function actually parses video frames, so fragments of the original "packets" can be fed to the decoder.) However, it returns out demux_ts packet's are mostly useable. demux_ts still adds an offset (i.e. ds->buffer_pos != 0) to the packets when calling internal parser functions, such as in parse_es.c. While this is unclean design due to mplayer's old video demuxing/decoding path, it can be easily be made work by modifying the packet as returned by ds_get_packet2(). We also have to change the packet freeing code, as demux_packet->buffer doesn't have to point to the start of the memory allocation anymore. MPlayer handles this "correctly" because it doesn't have a function that reads a complete packet.
