问题 I'm using the VideoJS player and have a CMAF video so I am using HLS and DASH. I'm also using all 3 types of DRM. Fairplay for hls, widevine and playready for dash. My question is should I include both hls and dash sources in the player and let the player decide which one to play? Or do I detect the browser and only insert the correct url based on that? Also DRM is the same. Can I just add all DRM to the player? Or should I only add the one that applies? 回答1: The use of HLS vs DASH is

问题 Here are a few commands I am using to convert and transize a video in mp4 format to a m3u8 playlist. For a given input video (mp4 format), generate multiple video only segments with segment duration 30s ffmpeg -loglevel error -i input.mp4 -dn -sn -an -c:v copy -bsf:v h264_mp4toannexb -copyts -start_at_zero -f segment -segment_time 30 30%03d.mp4 -dn -sn -vn -c:a copy audio.aac Apply video filter (in this case scaling) on each segment and convert it to a m3u8 format ls 30*.mp4 | parallel

问题 Is it possible to capture stream from webcamera(in front end) and stream it to server via hls or rtmp with pure js(no flash). And if there are another protocol which let send stream as stream(unlike hls), will be prefered. 回答1: I found solution. There is no (yet) any way to "convert" stream received from navigator.getUserMedia() to rtmp in front-end. But we can use MediaRecorder Api. In client Side const stream = await navigator.getUserMedia(options) const recorder = new MediaRecorder(stream)
