However at this point you won’t see any captions. Then Click “ok”, then “Play”, and you should now be seeing video. The field is blank by default, but to get captions you must specify the VBI device to use. This is a field I recently introduced into the upstream VLC product, so if you don’t see it then you probably need to get the latest version of VLC. The first field on the page is the “VBI capture device” field. Īs you normally would, specify the path to the /dev/videoX device and ALSA audio device (in the above example it’s /dev/video0 and hw:1,0), then click on the “Advanced Options” button. Because even in 2013 the V4L2 API still lacks any way to associate a /dev/vbi device with a /dev/video device, the path to the device node must be manually specified.įirst, go to “File->Open Capture Device”.

The key to getting captions to work is specifying the VBI device. Thinking that perhaps he was not the only person who had trouble figuring it out, I figured it would be worthwhile to walk you through the sequence. The screen name comes from the fact that I design utility class (>200MW) boilers for a living.I was on a call with someone a few weeks ago, and they mentioned that they had been unable to get NTSC closed captions to display within VLC on the HVR-950q. I'm actually an RPI alum and not a Purdue alum. In any case, if you want to have interlaced video display correctly on an LCD monitor you will need to either use a decoder with the interlacing option turned on (and remember to turn it off when you want to watch a progressive format video), or re-encode the interlaced video using a deinterlace filter. The reason for this is that if you try to de-interlace a progressive video source (most videos you are likely to have on your computer will be progressive) it won't play right. Take VLC for example: VLC has deinterlacing disabled by default. Ideally the decoder should do the deinterlacing for you, but in many cases the default option on decoders is to perform no deinterlacing.

The following link explains this a lot better than I did: What is Deinterlacing? Facts, solutions, examples. Conversely, an LCD monitor need a progressive video source so an interlaced video will have noticeable 'combing' effect when viewed on an LCD if no deinterlacing filter is used. A CRT monitor does not need the source to be deinterlaced so an interlaced video will look perfectly normal on a CRT monitor. You are correct that the monitor plays no role in the de-interlacing process, but that wasn't the reason I asked if the OP was using a CRT.
