I'm in the same situation as you. "streamer" has the same functionality as
xawtv's record feature, then there's mencoder and avidemux. I also tried
kino, but couldn't get it to do anything useful because it couldn't read
any of the formats I can record in.
What I'd like to do with my machine:
- record full-resolution TV. Possible with "streamer" (without dropped
frames if you do it right!), except that rgb15 format eats 1.3 GB per
minute. There's a nice fast GPLd lossless compression codec called
"huffyuv", but apparently there's no way to use it for encoding under
Linux. Hopefully mencoder will be able to use it at some point.
- Watch TV while recording. Apparently, this is impossible at full
resolution because the PCI bus is too slow to transmit the data twice,
but just a small preview window would be enough. I haven't found any
app which can do that, though...
- Cut out the commercials, remove black borders, deinterlace.
avidemux looks OK for that, except I think it can't read huffyuv.
- Encode to fit 700MB, or 2x700MB in two separate files. Possible with
avidemux.
Everything gets much easier if you only record at half of the TV
resolution, for example you can watch while recording, or use a more
processor-intensive encoder.
Cheers,
Richard
