libvorbis without encapulsation

I am not sure I understand exactly what you are asking, but libavformat
has a RTP packetizer that works for both Vorbis and Theora, implemented
in rtpenc_xiph.c.
But this packetizer is meant for use in the RTP muxer of libavformat
itself, and the RTP muxer relies on the packet's metadata, that, when it
comes from libvorbis, is derived from the fields of the ogg_pa...

asterisk 11 and no RTP
I have a CentOS 6.3 machine I installed Asterisk 11, worked fine...
I then tried to install on Cents 5.8, seemed to go fine... Then when I
placed a call I got this:
ast_rtp_instance_new: No RTP engine was found. Do you have one loaded?
Did a search and found issues with ARM and this problem but did not help
me, not using gtalk
or anything. Just call between two polycom phones on local network.

DVD NTSC video plays twice as fast when encoded with libtheora
https://roundup.ffmpeg.org/roundup/ffmpeg/issue1197
I had originally encountered this problem using ffmpeg2theora. I
switched to ffmpeg proper in an attempt to identify where the problem
was at, and found that the problem persisted. As a result I had
thought this was a problem with ffmpeg, but the ffmpeg folks seem to
indicate that this is specific to Theora (too much finger pointing I
think.) I

Define 6.1 and 7.1 channel mappings
...r designations used by home
theatre systems, which is the same set used by the Vorbis and Opus mappings.
The ordering follows the WAVE file format, rather than the Vorbis order
of other Xiph codecs. This matches what flac has done for the existing
mappings, and it allegedly what current tools like libavformat are doing.
Please consider applying this patch to have a definitive statement on
the channel map for implementors to follow.

P.S. This doesn't update the flac command-line tool to enforce this
mapping. That needs to be done as well, along with test files.

Audacious crashing (64bit)
Hello there,
My first post here and even my first CentOS (after years of Fedora).
Audacious is crashing at startup, here's the output:
audacious: relocation error: /usr/lib64/audacious/Input/ffaudio.so: symbol av_register_protocol2, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference
Does anybody reproduce? Would this reveal a problem (or my misuse) with
rpmfusion ffmpeg packages?

Opus in m2ts
Hi
Is there existing specification for encapsulation of opus in MPEG
transport stream.
The only thing I found is this draft
https://people.xiph.org/~tterribe/opus/ETSI_TS_opus-v0.1.3-draft.doc.
I compared it to
https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/mpegts.c and
there are
few differences

Why do you not want it? It is just a simple C struct to carry the
packet's metadata.

I have completed some from-git install documentation, available here:

I'll generalise it, transfer it to the wiki and tidy up the installation page
shortly.
