Hi guys, I'm pretty new to this list so excuse me if questions have already been asked for. I'm an MPlayer developer and I recently did a few work to support ivtv cards under our player.
First thing was a new pvr:// input that should be able to use V4L2/IVTV ioctl() to read from ivtv cards with no more needs to ivtvctl (at least for most common options). Anyhow, i'm currently working on a video output driver. I based my work on the old patch for MPlayer 1.0pre7 that was in misc/ from your SVN. It's now nearly integrated but i still have a few issues. 1. Does ivtv cards have audio output or just video (tv-out) ? Currently i'm sending MPEG-PES video data to the card but i wanted to know if i can do the same for MPEG-PES audio data. 2. I do have a problem with decoder filling. It seems from my tests that the decode needs something like 80 MPEG frames before being able to display a single picture. As a result, MPlayer renders a stream with desyncronized A-V. >From MPlayer view, audio and video packets are synced but the problem is that >audio packets are played immediately when decoded while video packets are >displayed with a 80 frames delay. Is there then a way for ivtv decoder to start displaying received frames immediately ? Otherwise, is there any way to known the exact moment where buffer gets filled (and so, the exact time where pictures will be displayed) in order to delay audio packets from the same amount of time. 3. Is there some place where all of the IVTV ioctl() are described ? (something more than just ivtv.h) Ben -- "My life, and by extension everyone else's is meaningless."
