Hello,
Hi.
I read some posts that a couple people here were using
the PVR 250 with iVTV driver. Is there any work being
done to be able to use this card and it's variants for
Freevo?
There sure is.
I just got my card working in Linux and it's pretty impressive since it just streams mpeg2 from /dev/video.
Sweet, eh? :)
From what I understand the iVTV driver uses the V4L2API. Does Freevo use some V4L program currently, or
does it just control mplayer to do everything such as
channel switching, tuner setup, etc..?
For regular v4l cards, like the brooktree based ones, freevo uses mplayer to watch tv and mencoder (by default) to record. The recording program is easily configurable and many people use mp1e, ffmpegrec, divx4rec, etc, instead.
I've had to play around with a test program (test_ctrl) that is part of the iVTV driver package which I think conforms to V4L2 API to change channels on the card and set the type of tuner, etc... Seems all that would need to be done is have Freevo control this test program that speaks V4L2.
Any thoughts on this? Shall I attempt to write something like this?
Even better. There are python bindings to V4L and Thomas Schueppel submitted some modules and a class to encapsulate them.
For watching TV we are moving towards timeshift playback where an mpeg stream (from ivtv or mp1e for regular cards) is written to a buffer and then mplayer plays back that buffer. Timeshifting is a WIP and you may find it in src/tv/plugins/timeshift.py. It is being worked on by Thomas and others, feel free to contribute. :)
For recording TV I am working on a new recording client/server which uses a recording plugin to do the recording. The first plugin was called generic_record.py and simply ran another process (mencoder/mp1e/divx4rec/record_ivtv.pl) to do the work. Last night I made another plugin (ivtv_record.py) specificly for recording using ivtv cards, it relies on the v4l2 python interface I mentioned. Right now it works good but doesn't yet support changing the bitrate and other codec options... it will real soon though. Again, any help is welcome. :)
