&audiocodec
Lets you specify the audio codec
Example:
&audiocodec=opus
Value | Description |
---|---|
opus | default; selects audio codec opus |
red | selects audio codec red* |
pcmu | selects audio codec pcmu |
pcma | selects audio codec pcma |
isac | selects audio codec isac |
g722 | selects audio codec g722 |
pcm | selects audio codec pcm* |
&audiocodec
on the viewer side can let you specify the audio codec; opus
(default), pcmu
, pcma
, isac
, g722
, red
and pcm
.&audiocodec=red
is pretty much sending two opus streams, with one as a backup in case of packet loss; support in Chromium 97 and up, but the only way I can so far tell that it is working is to check if the audio bitrate has doubled.&audiocodec=pcm
now will support 48khz and 44.1khz mono playback (48khz default), and if &stereo
is used, it changes to two-channel stereo 32khz.The existing
&samplerate=44100
option can lower the sample rate of this pcm mode (down to 8khz even), and hence the resulting audio bitrate. Since pcm is raw, &audiobitrate
won't work, so expect 550 to 1200-kbps in just audio bitrates per viewer.Last modified 4mo ago
