No picture streaming from SCFH DSF capture device

[dgells]

I am trying to stream from VLC 1.1.5 with SCFH DSF 0.41 as the capture device, but I only get a blank or black screen.

SCFH DSF Directshow screen capture filter

I have successfully used this SCFH DSF Directshow filter to stream from Windows Media Encoder and Expression Encoder with no issues, but I would prefer to use VLC. I have had some success in VLC using UScreenCapture instead, but I would prefer to use SCFH DSF because of it's wider range of framerates and convenient area selection features.

In VLC, I can Play from SCFH DSF and see an image.

Media > Open Capture Device > SCFH DSF > Play

with default options:

:dshow-vdev=SCFH DSF :dshow-adev= :dshow-caching=200

The SCFH DSF captured image plays on screen and will capture to uncompressed AVI with the Advanced Controls, Record button. The resulting AVI is RV32 rawvideo and plays in VLC, but I have not been able to convert or stream those AVI files. I get either an encoder error or a black/blank image. Anyway, I am only interesting in live streaming.

Here is a message window log from an attempt at streaming:

Thank you.

avcodec warning: almost fed libavcodec with a frame in the past (current: 1473968004, last: 2946106518)

That would indicate some sort of bug.

It might be avoidable if you use non-libavcodec video encoder.

avcodec warning: almost fed libavcodec with a frame in the past (current: 1473968004, last: 2946106518)

That would indicate some sort of bug.

Thank you for the suggestion. I just tried streaming to h264/mp4a and it's working. It shows a picture now.

Could you please suggest a non-libavcodec encoder in VLC for MPEG2 video?

I am streaming to a set-top box and MPEG2 video is the most compatible. When I use the UScreenCapture capture device instead, I have no streaming problems with the default mp2v to my set-top player. Also, my CPU is not fast enough for good quality H264 in real-time.

The other free MPEG-2 encoder I know is mpeg2enc but AFAIK it hasn't been ported for VLC.

Ok well, thanks again.

Can you tell from my log above if there might be any other settings I can try to get this capture device working with mp2v? Are there different :dshow, :sout or transcode options that might help fix this error? ("almost fed libavcodec with a frame in the past")

I am able to stream mp2v from a different capture device, UScreenCapture. I'm not sure why libavcodec mp2v would work fine with other capture devices and have problems with SCFH DSF.

If anyone has successfully used SCFH DSF as a capture to device to stream MPEG2 with VLC, please post your settings and VLC version. Or if anyone is willing to test and troubleshoot, please download the SCFH DSF 0.41 from the link in my first post to try it for yourself.

For now, I'll use the other capture device, unless anyone has more suggestions for making SCFH DSF work.

There is prolly a bug in either libavcodec or VLC that has something to do with timing method inconsistency. I would guess that VLC gets wrong timing info from that info, and while VLC can play the video, forwarding it to encoding with wrong timecodes doesn't work.
