[FFmpeg-user] sporadic rtmp live stream crashes

Tue Apr 1 00:50:38 CEST 2014

im not entirely sure then.. 

im not sure how you have things setup but you can always just do the transcode and send it right back to wowza in a native format such as flv... this way you have wowza doing all the fun stuff...

but just off the top of my head...

ffmpeg -i rtmp://wowza/private/stream -c:a libfdk_aac -c:v h264 -g 50 -f flv rtmp://wowza/live/stream

then you can just use the native wowza HLS url

http://wowza:1935/live/stream/playlist.m3u8

on first run i noticed lots of dropped frames so i removed -r 25 so ffmpeg will use the input framerate.

i tested this against a flv h264 aac stream on my own wowza setup (as i really dont know much about spark/speex).... so im not 'entirely' sure the you will have the same results.. but this might help =]

here is my command output

$ ffmpeg -i rtmp://wowza/private/stream -c:a libfdk_aac -c:v h264 -g 50 -f flv rtmp://wowza/live/stream
