Performance - MJPEG to WebM with ffmpeg/ffserver
Posted: Wed Aug 21, 2013 12:56 pm
Hi forum
I was wondering what kind of performance I could expect from a Raspberry Pi transcoding a MJPEG stream into WebM (VP8 video codec and Vorbis audio codec)? The setup is using ffmpeg to take the video stream from a USB Webcam, pass it to ffserver that transcodes it into WebM and provide it via http.
I am currently getting under 1 frame per second. Is this normal – what kind of frame rates have you other guys achieved?
I am using the following SW stack:
Latest Raspbian wheezy as OS
Latest “ffmpeg” and “ffserver” version (FFmpeg 2.0.1 "Nameless") compiled with required libraries.
Best regards
