The ivtv driver does not support the V4L2 Streaming I/O ioctl()'s for transferring video data buffers. It only supports the read()/write() calls. I'm not sure about ffmpeg, but mplayer is happy to read() the mpeg stream from standard input or the device node: # cat /dev/video0 | mplayer or # mplayer /dev/video0 Regards, Andy > Here is the ffmpeg command > ffmpeg -y -f:v video4linux2 -i /dev/video0 -f:a alsa -ac 1 -i hw:1,0 > -threads 2 -override_ffserver -flags +global_header -vcodec libx264 -s > 320x240 -preset superfast -r 7.5 -acodec aac -ar 44100 > ipgoeshere:port/dvbstest.ffm > > Disregard the DVB syntax, not relevant > > Any idea what is causing the error? > -- > To unsubscribe from this list: send the line "unsubscribe linux-media" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
