I test with mplayer. Example; mplayer tv://9 -tv driver=v4l2:alsa:immediatemode=0:adevice=hw.Em28xxAudio,0:norm=ntsc:chanlist=us-cable -vf pp=ci The above command works fine (both audio and video) with my Hauppauge HVR-850, but for the Kworld 305U I must change 'immediatemode=0' to 'immediatemode=1' otherwise the video frame rate is about 1/2 normal speed and about 1 minute later mplayer starts printing 'video buffer full - dropping frame'. According to dmesg the Kworld 305U loads the same firmware as my Hauppauge HVR-850, and (during separate test sessions) installs the same ALSA device; card 1: Em28xxAudio [Em28xx Audio], device 0: Em28xx Audio [Empia 28xx Capture] Subdevices: 0/1 Subdevice #0: subdevice #0 Dean -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
