hi.
after the reworking of the driver with the new simplified routing scheme
from Mike Isely (big kudos to him again for the overall care), i get
back working on the Terratec Grabster av400
http://www.terratec.it/prodotti/video_editing/grabster_av400/board.JPG
and indeed now it's really easy to get it supported in the new environment!
in attach there's the first iteration of the patch.
it's not ready and polished but at least it's a start.
i have to tell you i run a 2.6.23.9 kernel with v4l BUT without pvrusb2
in-kernel driver and using this latest isely.net driver:
http://www.isely.net/downloads/pvrusb2-mci-20071202.tar.bz2
you can simply patch this driver with the attached file and install the
module on your kernel.
BEWARE this patch CAN crash everything!! don't do it on a production
machine!!
this way, when you attach the device, the Terratec Grabster should be
recognized and start [*]. no firmware needed..
then you should switch to the composite input with this command (it
starts on input tv as default, but we don't have a tuner, i put it on
the right composite input anyway!):
echo composite > /sys/class/pvrusb2/unit-a/ctl_input/cur_val
maybe we could provide a different default input on module loading (on a
case by case based on the card type?)

note the cx2341x config: it's still NTSC based in my opinion (720x480
30fps..)
and you should get a color program stream with:
cat /dev/video0 > /tmp/prova.mpg
BUT i still have three glitches:
1- BEWARE! sometime the kernel oops (don't know why! maybe it's still
the missing tuner but still configured?), i'm going to provide more
details when it occurs again
2- the audio stream is too quick, no idea!
here you can see a sample broken stream (with my face!)
http://mhplab.cineca.tv/grabster-audio-broken.mpg
this what mplayer tells me about it:
==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
dec_audio: Allocating 4608 + 65536 = 70144 bytes for output buffer.
mp3lib: using SSE optimized decore!
MP3lib: init layer2&3 finished, tables done
MPEG 1.0, Layer II, 48000 Hz 224 kbit Stereo, BPF: 672
Channels: 2, copyright: No, original: No, CRC: No, emphasis: 0
AUDIO: 48000 Hz, 2 ch, s16le, 224.0 kbit/14.58% (ratio: 28000->192000)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================
maybe i need to change the cx2341x config; how can i do it using the
/sys/class/pvrusb2/*/ctl_ controls?
i did find a way to change audio sampling rate (ctl_srate to 44.1KHz)
but the audio then was completely missing on the stream..
what about change the video frame rate.. from 30 to 25fps? don't see a
fps control..
3- the svideo input is still slightly broken! with Luma2 i see the black
and white image BUT i tried evey ChromaX combination (4..8) and i got
only B&W or flat green (!)
do you have a hint about this?
let me know if it works more or less for you grabster owner too..
bye
