I have RTMP live stream with video and audio. I can get ogg audio live stream from RTMP and translate it to Icecast2 and get it on my site using JPlayer. Now i use such command:<\/p>\n

\/usr\/local\/bin\/ffmpeg -re -i rtmp:\/\/192.168.22.12\/live\/live1 \\\n-vn -acodec libvorbis -b:a 48k -f ogg - | oggfwd -p -d "" \\\n-g "" -u "" localhost 8000 somepass live2\n<\/code><\/pre>\n
Then I stream my live audio using Icecast2, but it is in OGG format, so mobile devices don’t play it (Android device has a time lagging near 30 sec before they start playing, iOS devices don’t want to play it).<\/p>\n
How can I transcode it to mp3 before sending to Icecast2?<\/p>\n
…<\/p>\n
\n
If you are using a (very) recent version you just could use ffmpeg for this. To test if your ffmpeg is capable to stream to Icecast, do the following:<\/p>\n
ffmpeg -protocols -v 0 | grep icecast\n<\/code><\/pre>\n
If this returns “icecast”, hooray, you can just do the following:<\/p>\n
ffmpeg -re -i rtmp:\/\/192.168.22.12\/live\/live1 -vn \\\n       -codec:a libmp3lame -b:a 64k -f mp3 \\\n       -content_type audio\/mpeg \\\n       icecast:\/\/source:pass@example.com:8000\/mountpoint.mp3\n<\/code><\/pre>\n
Replace source<\/code> with a specific username, if you have configured any, else leave it as source. The other things should be obvious.<\/p>\n
