Ok, forget about gstreamer, but it looks quite useful - no need to use gtk.
I found something better for our purpose ->
http://linuxstb.org/dvbstream.html . This prog uses dvb kernel access, but we can fake it and dump a TS stream like PVR does and feed it to dvbstream. Of course dvbstream has many options, that we don't need, for example setting a frequency of a card or swithing polarisation. We can't even do such things with our tv's hardware (no /dev/dvb/adapter0 and so on). The application looks quite simple and it seems possible to use it in our project.

I guess that program need code change too.
I want VLC anyway

I think we could use VLC via pipe, just by reverting stream in pipe to vlc process will work.
That means we could use streaming through VLC without code change on it.
With it also we could stream any other movie in the usb HDD, that attached to TV.
Also it might give us small advertise on videolan site, that might increase SamyGO awareness/popularity.

Hi, I'd be interested in just being able to play the PVR files as they're being recorded, or after as well. Does anyone have information about the format of the recorded data? My guess is that the mdb file is audio and srf is video, if someone knows what the containers and codecs are, we have a shot at playing them. I guess that the codecs are mp2 or mp4 as comes from the tuner. But container?
Edit: I tried VLC, and it seems that srf file is both audio and video. So it seems to understand the container, but it doesn't actually decode and play it.

In fact, I got this idea yesterday when driving car. It should be definitely possible to enable streaming TS content to the connected network client instead of PVR file. Also this could be also another way how to record channels - not from TV, but from PC. Anyway this would work only for DVB, not for movies.
And when brainstorming - if we could divert TS stream after demultiplexing (if I understood well previous posts), maybe it could be possible to "insert" different TS stream and allow receiving TS streams from network clients..

Majonezz, I think I misunderstood your post about playing files from PVR on PC. I thought you would like to, but when I read your post again I think it means you already can do this. Would you post how you do this? I tried a few things, but can't get the files to play.

First of all, i must say, that i'm an owner of B series TV, but the topic was interested for me and i've decided to drop a line here.
I have no idea how C-series recordings are constructed. If they are similar to those from B-series ( .TS files), then i suggest to use VLC player.

I see, that is different than in the C series. I get .srf files, and VLC player acts as if it were playing them, it even lists some information under Media Information. But, there is no audio or video, like the file was corrupted.

Same was for me: srf files from samsung C-series are protected by DRM ...
I suppose, it will be only matter of time when somebody analyzes encryption/decryption process and keys used by C series..

I realize that this comment is going to be obvious to everyone, but putting DRM in these files is pointless! No one tries to prevent recording the signal coming out of the Ext1 port, not to mention that there are innumerable recorders with tuners that don't use DRM in any way, and also what I record is freely broadcast without DRM to begin with. What is the sense of this?
