Hello,摩頭

http://farsight.freedesktop.org/wiki/CodecStatus

The status on this page is relative to the current CVS versions of gstreamer, gst-plugins-base and -good and the current darcs trunk of Farsight as of today (Sept 13, 2007).

Video

Theora

The payloader does not support putting the configuration information in-band. The payloaders also need to have a clock-rate of 90000 hardcoded according to the new draft.

MPEG 4 Video (MP4V-ES)

The payloader only sends the configuration information once at the beginning (it should re-transmit it regularly). You need to set the clock-rate in the gstcodecs.conf.

H.263

H263

It should work.

H263-1998

Farsight does not know how to create the right encoder/decoder based on the options/profile.

H263-2000

It should work

Audio

PCMA, PCMU, AMR, AMR-WB

Works

iLBC

Needs patch from http://bugzilla.gnome.org/show_bug.cgi?id=465146

Speex

Works if you specify the clock-rate (at 8000 or 16000) and use the patch from http://bugzilla.gnome.org/show_bug.cgi?id=465146

MPA

Works with mad and ffenc_mp2

L16

Will try to use alsasrc/alsasink directly.. so it does not work... We need something like.. sources are only used if there is nothing on src set.. And may some smart "static autoplugging" so it knows to stop adding elements if the src Caps is reached. We need encodebin!

Vorbis

There is currently nothing in the vorbis media caps to negotiate the rate. It also needs configuration data that needs to be transmitter either inline, in the SDP or by some other method. It should probably re-transmit it regularly like Theora and other similar codecs.
