Hello.
I am broadcasting a low-rate TV channel by satellite. The TV channel only consists of fixed
images that change once in a while.
Each image consists of a couple of I
frames only. No B or P frames at all.
The rate of that TV channel is 64 Kbps.
I am trying to receive my channel using the latest Linux version of VLC, compiled with DVB-S support. VLC does not display my channel. It
detects a TV channel, but it cannot display it.
It displays however any other channel
that has a higher bitrate.
Same thing with Mplayer and
Xine.
So I suspect this to be caused by the
lower level DVB driver used in Linux : the linuxtv one.
Moreover, some set-top DVB-S receivers
(like Neta and some Nokia) actually can receive my channel without
problem.
Some others with errors, and some not at
all.
What's in the DVB specification that
causes such discrepancy in the behaviour of low-rate
reception?
Is there something I can do (in the
linuxtv driver code, or elsewhere) so that I can receive my channel
correctly?
Thank you for your ideas.
