As a first task, I think that Rygel should support any DLNA-compliant
file to be streamed without transcoding. I found libdlna has a pretty
complete "database" of media formats and its corresponding DLNA
profiles. I you agree with this, I can try to rewrite it in vala as an
object hierarchy (Rygel.DLNAProfile, Rygel.DLNAVideoProfile, ...) as
time allows.

Related to this, I found that the PS3 recognizes mpeg files as DLNA
compliant and doesn't tell Rygel to transcode them. Where in Rygel
sources is this handled?

The problem seems to be that the default bitrate for ffenc_mpeg2video is
very low (300kbps). I changed it to 3Mbps and it improved a lot. By the
way, why don't you use mpeg2enc which seems to be the preferred encoder
for mpeg2?
