MJPEG Playback Issue

baggar11 · October 24, 2016 at 8:02 PM

Just got through testing with Openelec 6.0.3, LibreElec 7.0.3 and LibreElenc 7.09.007 alpha. I can't seem to get the Alpha version of LibreElec to play an MJPEG strm file for an http dlink webcam. No audio, just 640x480 MJPEG video. Testing was done on a Raspberry Pi 2.

Steps to reproduce.

1. Fresh flash of (Any)Elec listed above.
2. Go through wizard and connect to wifi network
3. Set timezone
4. Add video source that includes webcam strm file. --> user:pass@ip/video/mjpeg.cgi
5. Try to play strm file.

Both Openelec and LibreElec 7.0.3 were able to play the strm file fine. Alpha version of LibreELec gives an error about not finding the next file to play. Anyone else see this behavior? I can't imagine there being many folks viewing MJPEG streams on their Kodi systems. Possibly a compile time issue for the LibreElec build or a bug with Kodi v17?

Post a debug log. Enable debug logging. Include ffmpeg and video in component specific debug then try to play the stream.

See attachment for debug log w/video/ffmpeg options.

401 means "Unauthorised".
Does USERNAME:PASSWORD@192.168.20.10/video/mjpg.cgi work in a web browser?

Yeah, it is a valid http url when authenticated. As referenced in my original post, I tested Openelec and 2 x Libreelec versions back to back to back after noticing that the latest Alpha had issues with it. All are using the same videos CIFS share with the same .STRM file pointing to the same http address. If you like, I can capture the logs off a successful play? Perhaps the 401 is indicating that Kodi is not sending the correct user/pass?

I've attached a screenshot of Firefox playing the video to show it is a valid link

Attached is a debug log w/ffmpeg/video from LibreElec 7.0.2. Save CIFS share, same STRM file. Plays fine.

There have been some changes with how kodi passes URL parameters through ffmpeg in Krypton.
Probably best to post here: Kodi Community Forum - VideoPlayer Development
including description and debug log where the right dev may know what to do.

Thanks, I posted here. Fingers crossed.

STRM file with MJPEG video issue

Thanks for pointing me over there. Looks like it's already a confirmed bug. Fingers crossed it'll make it into the next Kodi release.
