Clément Bœsch dc7ad85c40 doc: use @command{} for commands. 2012-01-04 13:21:08 +01:00
Clément Bœsch e1d613515b doc: fix and clarify libx264 encoding.
tune, fastfirstpass and profile are not available through x264opts.
Since some FFmpeg options don't match the names used in libx264, add
libx264 option names as a reference when needed. And last thing, x264
don't have a manpage ATM, so prefer the x264 --fullhelp over the
unexistant manpage reference.

Stefano Sabatini a2ee2843c0 doc: create separate section for audio encoders
Having a separate section for audio encoders simplifies navigation
and is slightly more consistent with the rest of the manual.

Justin Ruggles 7f3a7b5c40 ac3enc: add channel coupling support
Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.
