Hello, currently I stream a h264 Video with an RPI3 Usb Camera, on my network. This works well, but one of my clients need mjpeg. this is command
ffmpeg -nostdin -hide_banner -loglevel error -input_format yuyv422 -f video4linux2 -s 1280x720 -r 10 -i /dev/video0 -c:v h264_omx -r 10 -b:v 2M -vf "drawtext=fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf:text='%{localtime}:x=8:y=8:fontcolor=white: box=1: boxcolor=black" -an -f rtsp rtsp://localhost:80/live/stream
How could I add the mjpeg codec to my installation the build:
sudo ./configure --arch=armel --target-os=linux --enable-gpl --enable-omx --enable-omx-rpi --enable-nonfree --enable-libfreetype --enable-libx264 --enable-libmp3lame --enable-mmal --enable-indev=alsa --enable-outdev=alsa
And how can I stream in mjpeg format with less cpu consummation. Is hardware acceleration on the Pi with mjpeg possible? My ffmpeg installation: ffmpeg version git-2020-02-22-c116dd8 Copyright (c) 2000-2020 the FFmpeg

The last two options (enable-indev and enable-outdev) have no effect. It looks like you should also remove "--arch=armel --target-os=linux", it would be a bug if they are not detected. In general, these options should only be used when cross-compiling (wsl is an exception), you are not cross-compiling though. mjpeg encoding should be supported by above build. Carl Eugen

How can I add *mjpeg_vaapi ?* Could i recompile it with different settings? Am Do., 27. Feb. 2020 um 19:19 Uhr schrieb Carl Eugen Hoyos < ceffmpeg@gmail.com>:

It will be available if your vaapi headers are new enough, I wonder if your hardware supports it. Please find out what top-posting means and avoid it here, Carl Eugen
