I use win7/32...if this has some meaning.

No let's try with ffmpeg since that is how I usually test extras sub made me think about it.

Code:

ffmpeg -f dshow -i video="USB Video":audio="Digital Audio Interface (USB Di" -vcodec h264 -acodec aac -f mpegts -| ffplay -i pipe:

[dshow @ 02f10a00] real-time buffer [USB Video] [video input] too full or near t
oo full (103% of size: 3041280 [rtbufsize parameter])! frame dropped!
Last message repeated 33 times

This message appear many times. After some time start window for watching, but nextpvr still did not recognize it as device.

Yes that would be bandwidth try -s 1280x720 like I used also try h264_qsv instead of s/w decoding

With this code:
ffmpeg -f dshow -video_size 1280x720 video="USB Video":audio="Digital Audio Interface (USB Di" -vcodec h264_qsv -acodec aac -f mpegts -| ffplay -i pipe:

I get this error:

Looks like you are missing an -i

Maybe try a few things yourself before quickly posting.

Sorry for my quick posts, but I don't understand anything about ffmpeg commands....for me this is like Chinese lang.

[mvallevand]

I understand but nothing is stopping you from reading up on it on the internet too. That being said my wife is Chinese and I can't learn the language not matter how much I try.

Many thanks for all of your help.
I will go in other way..As @sub says I will buy some Hauppauge device.
I think this should be better solution.
