Instead of just allowing to show preview images, we could also allow for providing a “real” live stream since tools like FFmpeg support generating streams and we include a web server to deliver them anyway.
Generating a stream could look like this:
ffmpeg -re \
{{ INPUTOPTS }} \
-c:a aac -ac 1 \
-c:v libx264 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p \
-flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 \
preview/preview.m3u8We could even reduce system load by using this for the recording, ingesting a concatenated transport stream at the end. But that needs some more investigation.
