The VideoLAN Forums

Hi,

I've been googling all weekend like a mad man, but nothing seems to address the specific problem i am facing, so here goes.

The Problem:
I can't get VLC to open my DVB-C tuner, even though other programs can, i can scan for channels and czap to them with the dvb-tools and use programs like kaffeine, mplayer and mythtv without any problems. But VLC just dies, i think during the tuning process / opening of the adapter.

My setup:
Ubuntu Jaunty / Linux 2.6.28-11 i686 (With the newest V4L drivers installed)
VLC 0.9.9a

TV Card = Technotrend C-1501 + CI + irdeto cam

Operator = Stofa / Telia
Transponder freq= 346KhZ
Symbolrate= 6900
QAM= 64
NetworkID= 0

The command i use for launching: The program i tried to play here is a unencoded free channel (DR1), although i can watch encoded ones with the other programs.

And this is what happens What i find disturbing are these lines: I also tried getting VLC to just play my channels.conf generated with the dvb-utils/tools but the result is the same. I really hope someone has some help to offer on this one, because i'm going loco! And i also really hope that some people out there, can use this thread when trying to get DVB-C working

Best Regards

Hmm apparantly making a post here helps my thinking, Just looked at the output from the channels.conf, and the channels are at different frequency's and uses entirely different modulations. So for playing DR1 i used.
Notice also that the channel is at 426MhZ, well it sort of solved my problem, but i still can't get VLC to read and play the channels.conf file :/

Using
$ vlc -vvv channels.conf (same file as the output i posted earlier resides in)

What am i doing wrong here?

PS. Also watching encoded channels is foobar, but that belongs to another thread i guess...

Okay, now i got everything working except the vlc opening channels.conf part. But i got encrypted channels playing, instead of the :programs=XXXX,XXXX i used :program=XXX where XXX = The last number in the line of a program in the channels.conf file.

A bit weird? Maybe someone with some technical insight might enlighten a lesser being?

Now i got this little shell script wich i use for streaming dvb-c channels via http over the internet, it works great, except my 3Ghz Core2Duo seems to have problems transcoding the Highdef 1080p channels mpeg4 stream to h264 and streaming it again :/

Playing channels.conf is vlc dvb://channels.conf IIRC.

I got it running of the channels.conf generated by the scan tool from the dvb-tools package (http://www.linuxtv.org). I am unsure if it had anything to do with it, but i added the repositories for VLC V1.0 RC1 and upgraded to the release candidate, but i also changed the command to include the full path to the channels.conf file:
Now i get all the channels in the playlist, and i can choose between them and everything is perfect. Now i just need to be able to change between playlist items, via a custom made interface. But that's an entirely different thread i think.

Ok, so all is good?

Yeah, the only thing bugging me crazy now, is that when i stream this with fx the http or mmsh protocol, when i change between item's in the playlist the stream dies at the client side while changing to another channel in the playlist, then i have to press play again to get the client to resume play after each channel change. Also resizing 1080p channels to fx 720p or even maybe different transcoding parameters via the playlist would be a nice feature.

I'm not sure if the channels.conf combined with an rc interface is the way to go for me. What i'm trying to do is make a webbased player that can change channels and also record on the active channel.

But for now everything is good, sort of

--sout-keep when you stream.

That did it for me! hmm now what can i find to bitch about now....

Subtitles from the dvb stream? tried adding scodec=dvbs,soverlay to the transcode options both with and without the soverlay option. But no subtitles to show.

Here are the output from the rc interface for the channel. It looks like the teletext subtitle is there for the grabs? theres a strack set/get option in the rc interface but can't get it to do anything?

I am afraid subtitles blending (overlay) is not good in VLC. Patches are welcome.

Could use some expert hint's again. I am not sure where it wen't wrong but now the --sout-keep don't work for me any more.

*EDIT* This started somewhere inbetween 1.0.0 and 1.0.1 i think, and is the same with 1.0.2 *EDIT*

Mozilla Plugin completely freeze up when changing playlist item. I then have to reload the page containing the mozilla plugin embedding.
When i use the normal VLC the video just stops, when i then press play again it works fine and shows the new channel/playlist item.

Tried adding gather to the vlc instance but that does nothing. (suggested here http://wiki.videolan.org/Common_Problem ... working.29)

My VLC command looks like this: I have tried analysing the debug information, and what strikes me from that output is the lines from when the playlist goto xx command is issued. Look here: I can't post the debug info in it's entirety, theres simply too much information for a forum post.

I tried doing a second vlc instance that just streams the first stream to see what happens heres what it outputs when the playlist item of the first instance is changed:
Hope somebody will give this a look or has a hint for me, been googling like a mad man the last 2-3 weeks.
