I bought another camera, this time one that does MJPEG.? For some
reason, I can't seem to get Motion to read the MJPEG stream, even though
it works fine in Firefox, Opera, and Chrome. The RTSP stream works fine
in Motion.? What I get in the log for the MJPEG stream is
*[4:ml4] [CRT] [NET] [Nov 26 21:24:50] netcam_start: libjpeg
decompression failure on first frame - giving up!**
**[4:ml4] [ERR] [VID] [Nov 26 21:24:50] vid_start: Netcam failed to open*
This camera has three resolutions, which apparently cannot be changed:
*1280x720*, *640x360*, and *320x180*. I seem to remember a long time ago
there was some restriction in Motion where the video size had to be a
certain ratio, *4:3* I believe.? I looked through the docs and couldn't
find any reference to that though.? Am I mis-remembering it? Is that
still a thing?
Also, the docs indicate that you can use an /mjpeg:/// or /mjpg:/// URL
in the configuration file and Motion will translate it to an http://
URL, the purpose being to force MJPEG decoding.? Neither works for me.?
The former tries to interpret the stream as RTSP and the latter just
gives a syntax error.

Which version are you using? Can you upload the full "-d 7" log somewhere?
