Like everybody else on this list it seems, I am working on building a PVR. Mine is basically a collection of third party apps, but with some smoke and mirrors to make it a little more seamless, and using lirc for the remote control interface. So far so good. One problem I have run into is with sound when recreating the pause-live-TV feature. What I am doing is this: - when the "pause" button is detected by lircd, the recording is started. (mp1e) - The TV app (xawtv) is killed - I grab a screenshot from the capture driver, and show it using xv with an overlaid "Pause" graphic. Then I wait until the play button is pressed to start the playback. When playback resumes, now a bit behind the live TV, I use "xine -pfq" which starts from where the pause was taken, once it's up I kill off my xv screenshot and it all works. However, the two running processes (mp1e and xine) clash over /dev/dsp, because one wants it open for reading and one wants it open for writing. I am using the oss sound drivers. If I switch to ALSA drivers or others, is there a way I can open a sound device for reading by one process and for writing by another? It actually works fairly effectively other than that, so it seems worth implementing. -- Trevor Boicey, P. Eng.
