Hi,
I'm using a Plextor ConvertX with latest CVS and when I press the skip ahead/back button while watching recordings (or live TV), I get around 1 second of blocky MPEG4 junk before the video plays normally again.
Looking at NuppelVideoRecorder.cpp, I can see it's requesting a key frame to be generated every 30 frames, and sure enough if I reduce the "gop_size" passed to the GO7007IOC_S_COMP_PARAMS ioctl, the length of time I get blockyness is reduced accordingly. Looking at the plextor docs, the only other thing I could think of trying was the GO7007_MPEG_REPEAT_SEQHEADER flag but it didn't make any difference.
I also have a WinTV PVR-350 and I don't see this problem on recordings made with this and then transcoded to MPEG4.
Is there some code in the skip ahead/back handling that seeks to the nearest keyframe when skipping, and it's failing for some reason with the GO7007-generated MPEG4 streams?
If anyone has any suggestions on where I should look to fix this, please let me know.
Cheers Jack
