Just a quick follow-up to let you know that live555 works quite well distributing low frame-rate high resolution video. My application gets bitmap images from a panoramic camera at a frequency of between 1 and 4 frames per second. I convert these to RBG24 "frames", pass them into the FFMPEG enco

[Live-devel] Low Frame-rate Panoramas

2017-04-11 Thread Weber, Patrick
I'm working on distributing live panoramas and was wondering if live555 is suited to this application. Some particulars: Frames are 2160 x 1080. Frame rate is around 1/second. I'll be using either MPEG4 or H264 for encoding. Is this do-able with live555? If so, any "gotcha's" I should be aware o
