As far as I can tell, you cant avoid taking the CPU hit of the conversion - the format/encoding of RTSP vs. I reduced my CPU load by configuring the camera to reduce the source's framerate and resolution until it was an acceptable load on.

I've written it up in more detail here: Converting RTSP to HTTP on demand. The method used in that player is quite similar to MJPEG Streaming: video. Rip an M3U8 (video HLS) ffmpeg -i "" -c copy -bsf:a aac_adtstoasc out.mp4 Use the PI to capture video as h264, merge audio from usb and use ffmpeg to.

What is not implemented: Generating quantization tables from Q-factor. Only instead of saving H.264 stream to file, it converts MJPEG stream to JPEG files according to according to RFC 2435 standard. ![]() These are FFmpeg commands I use on a regular basis and rather than keeping them to myself I figured it'd be good to share!įor the sake of simplicity, the filenames I use in the examples below are in.mp4 and out.mp4, though you can use your imagination to picture blah.mov or audio.wav on a case-by-case basis: This is based on RTSP communication example by GriffinRU. ![]()
