I have ben struggling with this for quite some time; Essentially what I'm trying to do is broadcast my webcam from within the Browser to Ffmpeg on the server to convert into a .m3u8 HLS live stream. But I am having a few problems with video playback I initially thought it was CORS and cross origin headers however now I am thinking its to do with the way I'm trying to encode the media.
I did a ffprobe on the input this was the response;
SERVER:key destination set to:1618380585-6666-863686008-4444-21
FFMPEG:Input #0, matroska,webm, from 'pipe:':
Metadata:
encoder : Chrome
Duration:
FFMPEG:N/A, start: 0.000000, bitrate: N/A
Stream #0:0(eng): Audio: opus, 48000 Hz, mono, fltp (default)
Stream #0:1(eng): Video: h264 (Constrained Baseline), yuv420p, 640x480, SAR 1:1 DAR 4:3, 30.30 fps, 30 tbr, 1k tbn, 60 tbc (default)
I am wondering if someone could help with the ffmpeg parameters; I am currently using the following;
var ops=[
'-r', '17',
'-i','-',
'-strict', '-2',
'-vf', 'scale=w=1280:h=720:force_original_aspect_ratio=decrease',
'-c:a', 'aac',
'-ar', '48000',
'-b:a', '128k',
'-c:v', 'h264',
'-profile:v', 'main',
'-crf', '20',
'-g', '48',
'-keyint_min', '48',
'-sc_threshold', '0',
'-hls_time', '4',
'-hls_segment_filename', '/var/www/html/streams/segments/streamKey-date-%02d.ts',
'-hls_base_url', '/streams/segments/',
'/var/www/html/streams/streamKey.m3u8'
];
I have also run into other problems and I was also wondering if i needed to build ffmpeg differently; here is the current build I am running; I only wonder this becuase when i try to add the -hls_playlist_type live parameter I get a response of not found.
