Today I bought a Pinnacle PCTV Pro USB TV Capture Card to capture the output of the game consoles, since it has 3 inputs (Antenna, Composite and S-Video) 3 gameconsoles may fit into it :)
There is an issue with the audio, I'm working with 'tvtime' to see the TV
At the beginning by running the following
- $ tvtime --device /dev/video0 --vbidevice /dev/vbi0 --input 0
The problem basically is the capture card comes with a sound card and the audio from the TV channels is dumped into this new card, since I'm using my primary card I expected all audio went through it, but it ressult it wasn't, so I had to use sox to have a "digital wire" (formally a pipe) connecting the output from the usb audio card with the input of the primary audio card.
the sox usage info was obtained from the following sources
My command to load tvtime and pipe te audio to the correct card is:
- $ tvtime --device /dev/video0 --vbidevice /dev/vbi0 --input 0 & sleep 1 && sox --channels 2 -sw --rate 44200 --type ossdsp /dev/dsp1 --type ossdsp /dev/dsp
- Load tvtime and sleep 1 second, after sleeping (double ampersand) launch sox
So far I have only seen the signal with audio comming from antenna input, even if I connect the RCA audio to the device via RCA-to-3.5mmPlug adapter doesn't make any difference, the sound input is grabbed from the last tunned channel on Antenna input.
I hope to get the audio working from Composite or S-Video input, else I'm just bypassing the sox part
I believe that's all for now
