Hey everybody, i was just wondering, did any body try MPEG1 recently?
i just tried it and it looked broken to me. i am using rc2.n and ntsc/352x240 streamtype = IVTV_STREAM_MPEG1. well, passthrough already seems broken with non full resolution&MPEG1 turned on. it works with 352x256&MPEG2. even though i dont understand why the codec settings should affect passthrough. when using passthrough the upper half of the screen shows the live picture, the lower half a alternating two still frames of the picture that was there before switching to a lower resolution. actually the recorded mpeg1 video looks exactly like that. you might want to take a look : http://www.okkiel.de/download/mpeg1-broken.mpg my code looks like this i first get the current codec/format settings and alter then alter them like this fmt.fmt.pix.width = 352; fmt.fmt.pix.height = 240; codec_settings.stream_type = IVTV_STREAM_MPEG1; codec_settings.audio_bitmask = audio_bitmask; rc = 0; rc = ioctl (fd,IVTV_IOC_PASSTHROUGH,&rc); if ( rc < 0 ) { logger ("couldn't disable passthrough",1 ); } logger (" ioctl S_CODEC",2); rc = ioctl ( fd,IVTV_IOC_S_CODEC, &codec_settings ); if ( rc < 0 ) { logger ("couldn't set video codec options",1 ); close ( fd ); return (-1); } rc = ioctl ( fd,VIDIOC_S_FMT, &fmt ); if ( rc < 0 ) { logger ("couldn't set video format",1 ); close ( fd ); return (-1); } thanks, ben ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
