compared to raw. For example:
MPEG-TS consists of 188-byte packets, each with a header of at least 4 bytes
(usually 4). In addition, there are less frequent PES headers of 9 or more
bytes, and the occasional PAT/PMT. This does not explain the overhead you are
MPEG-TS is often padded to a constant bitrate, but I don't think the muxer
in libavformat currently does this. If you upload a sample someone might be able
see what's going on.
