Hello all,

I just tried to watch a MJPEG stream from a D-Link DCS-900 network camera.
Setup seems to be OK, but then there are only messages like that:

Code: Select all

[00000295] mjpeg demuxer debug: MIME boundary not found in 15360 bytes of data

I'm using

Code: Select all

VLC media player 0.8.6 Janus

This was my command line:

Code: Select all

vlc -vvv http://192.168.100.200/MJPEG.CGI

I had a look at the messages and this is what I got:

Code: Select all

If you look at

Code: Select all

[00000292] access_http access debug: Content-Type: multipart/x-mixed-replace;boundary=--video boundary--

then all looks ok, but if you look at

Code: Select all

[00000295] mjpeg demuxer debug: Multipart MIME detected, using separator: video boundary--Content-length: 7958

it seems quite clear what causes the problem.
The separator should be

Code: Select all

--video boundary--

and not

Code: Select all

video boundary--Content-length: 7958

Kind regards

I Have the same problem whit a camera CAS-300 (aparently have the same system),I try to fix vlc, but it's not problem of vlc. The problem is in the software of the camera. I do wget -S http;//theip/mjpeg.cgi to see the header sended by the ip camera and i get this.

--video boundary--Content-length: 61432^M
Date: 2000-01-01 00:08:13 IO_00000000_PT_000_114^M
Content-type: image/jpeg^M
......

The separator must have a new line carrie return at the final (^M), should by like that

--video boundary--^M
Content-length: 61432^M
Date: 2000-01-01 00:08:13 IO_00000000_PT_000_114^M
Content-type: image/jpeg^M

For that reason vlc fails.

The solution it's change the firmware of the camera. But yet i' dont now how.

My best regards

I have the same problem

I'm using Linphone to set up a VoIP call, I want to use my Network camera (panasonic BB-HCM331) to set up the video connection. Linphone uses the /dev/video for video input.

Is there a way to connect or send trough the IP stream from the camera to the /dev/video input.

I'm trying VLC alltough it doesn't seem to work

Capture Network Stream:

Code: Select all

http://user:password@192.168.xxx.xxx/nphMotionJpeg?Resolution=320x240&Quality=Standard

I get error containing the following message:

mjpeg demuxer debug: MIME boundary not found in xxxxx bytes of data.

I'm using the ffmpeg decoder.
