Would you mind sharing the ffmpeg commandline? What software do you use for transport segmenting? May I ask what content delivery network you are using? Are you paying for it or did you roll your own? I've recently experimented a bit with https://github.com/carsonmcdonald/HTTP-Live-Video-Stream-Segmenter-and-Distributor -- http://blog.kyri0s.org/post/271121944/deploying-apples-http-live-streaming-in-a-gnu-linux It worked, but not reliably. At some point I gave up and went back to dual solution: ffserver (flv, x264, nellymoser - single-server) and icecast2 (ogg, vorbis, theora - multiple servers w/relay). Both driven at the same time by custom c code (basically a fancy 'tee (1)'). It still leaves default apple handhelds in the dark; but I learned to stop worrying and love punishing proprietary lock-in :) Cheers! robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
