[MPlayer-dvb] Input from demux (not dvr)

[Andrea]

Hi,

There has been a change recently in v4l-dvb allowing to send the output of a filter to the demux
keeping the TS nature of the stream.

I personally think that it would be very interesting to be able to run mplayer from the demux so
that one can have multiple instance running at the same time.

It goes without saying that there is only 1 frequency.

Still it is possible to set only 1 filter per demux, so to watch video+audio one has to get the
whole TS and select via -aid and -vid.

1) is it possible to set a filter "per program".
2) would it be worth extending the demux driver in kernel to take more that 1 pid per filter?

Anybody interested?

do you mean that multiple pids can be repeated to multiple client
programs?
If so it's what I've been asking a lot of time in linux-dvb

That has always been possible (with PES data).
The new feature is multiple TS streams to different clients via the demux.
Beforehand, only the dvr could get TS data, and the dvr can only be opened once.

I have not yet understood how to handle PES streams. I find easier to manage TS streams.
I've been able to play audio PES data via mplayer, no way with video.

I have a problem though: a demux can only get 1 filter so, to get audio pid + video pid

1) get them via 2 different sources (2 demuxes). Can mplayer cope with that?
2) get the whole TS and select audio pid and video pid via the command line arguments -aid -vid
3) extend the dvb kernel driver to accept multiple pid filter for each instance of a demux
4) get only 1 pid...

Is it easier for mplayer to handle TS data or PES data?

As soon as I have a clear view.
I have already tried option 2, but I think it is a waste of space...

Any suggestions?
