[Live-devel] X-SV3V-ES video type

Wed Mar 8 16:54:56 PST 2006

Hi,

I have been trying to view my University's streaming video content
using Mplayer and Linux.

I installed an older copy of the live555 library I got from the Fedora
Livna rpm repository; when I used -rtsp-stream-over-tcp I was able to
hear the audio, but I've still had no luck with video. Without using
stream-over-tcp, it didn't work at all, it just said (after the usual
output):

==> Found audio stream: 0

and did nothing (though my computer was receiving lots of udp packets).

With stream-over-tcp, I get the following output (verbose, but edited
a bit for brevity and privacy):

I thought maybe if I changed live555's source code to treat X-SV3V-ES
as X-QUICKTIME it might work, but when I tested that I got:

I don't know what video type SV3V-ES is, I think it might be a
sorenson codec? Probably SVQ3? Any way to hack mplayer/live555 to
treat it as such?

I tried to run the latest version of the live555 library (compiled
myself), and I get a lot more errors, and nothing works now, not even
audio:
- Some of these interleaved through the output, associated with long pauses:
Unable to determine our source address: This computer has an invalid
IP address: 0x0
- And after the 'Found audio stream' message, a stream of continued
messages like:
Discarding interleaved RTP or RTCP packet (19 bytes, channel id 2)
Discarding interleaved RTP or RTCP packet (84 bytes, channel id 3)
Discarding interleaved RTP or RTCP packet (1450 bytes, channel id 2)

Without -rtsp-stream-over-tcp it once again pauses after 'Found audio
stream' message.

Any help is appreciated,
