DVB support for Windows

[kenself]

By default I am capturing all channels at once. Reason is that I wanted to minimise the amount of windows code so I am capturing the stream right at the tuner device.
On the other hand, for my own purposes I need to be able to select a single channel. I usually stream across my LAN but I dont have the bandwidth for multiple channels.
I am currently learning how the VLC TS demux works so I can plug it into my own module. I plan to allow the program id to be selected or let -1 mean all channels.

Latest update is that I do not need any additional code to select a program from the muxed transport stream. Its all handled in the command line. So far I have done just basic testing which shows I can dump the entire stream straight to file for later payback; or i can run it through the TS demuxer (--demux=ts) and select a single program (--programs=nnnn) which I can then write to a file or transcode into MPEG-PS or playback on the screen. I'll do a little more testing but so far it looks pretty good.

Right now I am cleaning up the code to conform to VLC coding conventions and sorting out which extra DX 9.0 header files are needed that are not yet in mingw.

All coding is finished and tests out OK so we are ready to rock and roll. Hope to make it into VLC 0.9.0

A quick recap on the features:
All channels muxed into a single TS stream are captured
Supports multiple tuners - if it can't capture on one it tries the next one
Currently only supports DVB-T. ATSC support has been coded but not implemented since I cannot test it. DVB-S and DVB-C are not implemented since I cannot test them but these should not be difficult.
All demuxing uses the VLC TS demuxer. However, the filtergraph only works if I connect the DirectShow MPEG2 demux and Transport Information Filter
Standard VLC functionality allows selection of which channel to display and which channel(s) to stream or save to file

Woohoo! Sounds good

Question:
Is there the ability to choose the video and audio PID's per channel ?
Some channels are broadcasting the same program on different PID's because of different video resolution (eg 4:3 and 16:9) and different audio languages (eg ENG, FRA) and/or format (eg Stereo, AC3) ?

Well done Ken!

I've been waiting for over 18 months now to hear of some movement on VLC streaming DVB-T. I'm looking to use it to stream TV to my media player (DSM-320) - it's possible to do but there's just no software out there to do it under Windows.

Thanks from all of us who have been waiting for this.

Outstanding KenS!

D'you think you could fire a reply in here once it's incorporated into 0.9.0 in a nightly build?

Can't wait to test it out

Would be nice if we had access to this part of VLC via the ActiveX component too

Great stuff.
I must confess I gave up lobbying for this nearly a year ago. Nobody amongst the core VLC dev community seemed to appreciate how critical this feature is.
But you picked up the ball and (apparently) did it all on your own.

This will give VLC a couple more years of life (at least).

Man of the year!

It should be incorporated into VLC 0.9.0. Yes.

A future day, in a NB.

Please let us know as soon as it will be available in a nightly build.
I will test it.

Thanks,
Alessandro

What I've done is to tap into the stream as close to source as I could, so that any features of the standard VLC TS demux can be used. This certainly lets me pick specific channels (--programs=nnnn) and IIRC should allow you to choose video and audio pids. I have been able to select audio PIDs from the menu but don't know of any broadcasts with multiple video.

Come on, can't wait to test it
