Hey,
Anyone who knows me from snapstream will know closed captions are a big bee in my bonnet. I'm toying with switching to gbpvr but wanted to find out before I start if it currently supports closed captioning ?
To be specific; I record using Hauppauge PVR250's DVD Stream with 'insertCCinDVD' set. This embeds the closed caption data as a GOP user packet in the mpeg2 file. The nice thing is - intervideo + cyberlinks decoders will actually decode this data into a line21 caption display so if you can hook the line21 output pin from the mpeg2 decoder up to the video mixer filters - you can have closed captions even from the recording video. No worrying about subtitle files, vsfilter or anything like it.
SS are being anal and wont let me hook up that line21 pin - There are some issues about which line21 decoder you select (one handles odd/even fields, the other doesn't and shows garbage) but if you could allow a setting to specify the guid to connect - (registry hack or config app extension.. don't mind) - you'd make me a happy ... er. something.
In theory the MVP can also support them - hauppauge confirmed the hardware can show closed caption data on a tv but they have not written the firmware/player to handle the data and have no plan to do so. A shame but I'll take what I can get now and stick to captions on the main htpc.
So sub; can you do this already? would you be willing to accomodate the request? If you need any more info let me know. be glad to help or supply sample files to test with as you like.
