Hi, many modern IP cams dont support MJPEG and if, than in very low resolution. My 4Mpx Hikvision cam supports only 640x360 MJPEG. We totally need implementation of this. :( Modern cams support H.264, H.264+, H.265 and MPEG.
Yes, I readed post about licences and non free codec... but H.264 and MPEG are playable on Linux with free packages without any problems.
