[Live-devel] Unable to proxy mjpeg with live555ProxyServer

Hi there,

I have an IP camera that gives MJPEG over RTSP, I'm trying to proxy the
stream with:

$ live555ProxyServer rtsp://192.168.0.221/live2.sdp

When I use the openRTSP client like so:

$ ./openRTSP rtsp://127.0.0.1:10110/proxyStream

The output looks like this: http://pastie.org/7167135 - live555ProxyServer
is vanilla with the only change being I hardcoded it to use port 10110.

When I look at the output files, I get valid audio but the video-JPEG-1
file is empty.

When I try to play the proxy stream with ffplay, I get:

[rtsp @ 0x7f8daa81ae00] Received packet without a start chunk; dropping
frame.
[rtsp @ 0x7f8daa81ae00] Unimplemented RTP/JPEG type 12
[rtsp @ 0x7f8daa81ae00] Unimplemented RTP/JPEG type 39
[rtsp @ 0x7f8daa81ae00] Unimplemented RTP/JPEG restart marker header.
    Last message repeated 8 times
[rtsp @ 0x7f8daa81ae00] Unimplemented RTP/JPEG type 23
[rtsp @ 0x7f8daa81ae00] Unimplemented RTP/JPEG type 6
[rtsp @ 0x7f8daa81ae00] Unimplemented RTP/JPEG restart marker header.

I am able to play the camera stream with ffplay rtsp://
192.168.0.221/live2.sdp

Any ideas?
