Uncompressed image stream via http

[paulspignon]

Linux on a proprietary portable device, with USB camera, v4l.
Wifi streaming via HTTP, capture stream in VLC (or iSpy) on Windows 7.
Some cameras provide MJPEG, with that I specify "Content-Type: image/jpeg\r\n" and that's fine.
Others provide only uncompressed YUV 4.2.2 frames.
In that case I of course set
format.fmt.pix.pixelformat = V4L2_PIX_FMT_YUYV;
but I don't know what to set for Content-Type to get VLC to show anything.
If I just leave it at image/jpeg VLC captures the stream, and will record it, calling it an .avi file, but shows only a blank screen.
Does anyone have a suggestion, please?

Nope Jean-Baptiste, afraid that doesn't help, same behaviour.

There is "video/raw", but it is only specified over RTP (and VLC does not even yet support raw video over RTP). Your question has no answer.

Instead, you should use the format specified at http://wiki.multimedia.cx/index.php?title=YUV4MPEG2 and leave the Content-Type alone,
e.g. "application/prs.pignon.rawvideo".

Hi Rémi. That link was very useful, kiitos. I was working on inserting the correct header and frame separator data in the stream. Unfortunately their domain just got suspended , no idea why, leaving me a bit stuck. Do you happen to know a good alternative.
