My setup is 2.4GHz P4 running SuSE, kernel 2.6.8-24, 1G RAM. I'm using ivtv 0.4.0 with a Hauppauge 350. I don't use the decoder output of the 350, I use the xv/yuv mode and the framebuffer for a headless MythTV 0.18.1 system. Video is NTSC, kernel deinterlacing.
I am experiencing dropped (output) frames whenever the decoder is operating while I'm watching video. For example, if I'm watching a pre-recorded show and Myth is recording something in the background, every second or so a frame is dropped or perhaps two are shown in reverse. The same for simply watching Live TV through the ringbuffer. However, if I watch a recording while the encoder is doing nothing, then there is no problem. The video recordings are fine, it's just the playback that suffers while encoding is on. The visual effect is that of a sudden "jerk" in the image. This makes watching some things annoying, especially those videos with smoothly moving backdrops. I'm loading ivtv with the options "ivtv_dynbuf=0 mpg_buffers=8 yuv_fixup=1 ivtv_debug=1 dec_yuv_buffers=4 max_dec_yuv_buffers=8". The fixup stuff is because I was trying (unsuccessfully) to get Myth to read from the 350 as a raw frame grabber. Any help is much appreciated. _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
