HDMI to USB grabber

[bohosh]

I'm running v5.
The command line that works for me is:
ffplay -f dshow -video_size 1920x1080 -framerate 30 -vcodec mjpeg -i video="USB Video":audio="Digital Audio Interface (USB Di"

[mvallevand]

That's not going to work with NextPVR I already gave you the parameters you need to test with yours don't look complete either.

Code:

ffplay -f dshow -video_size 1920x1080 -framerate 30  -i video="USB Video":audio="Digital Audio Interface (USB Di"  -vcodec h264 -acodec aac -f mpegts

That's what I get

30 -i video="USB Video":audio="Digital Audio Interface (USB Di" -vcodec h264 -

That's why I wrote that the example you posted looked incomplete.

Here is a full script that works for watching...if this helps you.

Are those ffplay.exe or ffmpeg.exe parameters?

[bohosh]

Sorry I don't understand your question.

[mvallevand]

It won't matter if it is ffplay or ffmpeg but I am asking for ffplay now.

I am thinking you need to spell out "audio=Digital Audio Interface (USB Digital Audio)"

Martin

[bohosh]

Maybe thats what you need:

For fun I'd try what I suggested.
