Re: [vdr] Streamdev script to stream audio only?

Re: [vdr] Streamdev script to stream audio only?
Just a question: Do you need to transcode the audio stream? Why don't use the elementary audio stream from the DVB source? something like this: http://www.fuley.ro:3014/ES/S1.0W-1536-705-30511+1 István On 2011.12.06. 17:00, Teemu Suikki wrote: Hi!

Re: [vdr] Streamdev script to stream audio only?
I actually managed to get this working quite well, here is my externremux.sh: echo -ne 'Content-type: audio/mpeg\r\n' echo -ne '\r\n' ffmpeg -f mpegts -i - -vn -acodec libmp3lame -ab 32000 -ar 44100 -ac 1 -f mp3 pipe:1 Nothing more needed really, simple is beautiful. :) However, there is one huge problem. It takes ages to start streaming, and then the audio is a full minute behind.. The start delay is fine, but I need more realtime streaming. I'm going to York UK tomorrow to watch Snooker UK Championship, and I was planning to hear the finnish commentary from Eurosport. :D It's pretty much useless if there is a minute delay.. -- Teemu 2011/12/6 Johannes Truschnigg : > Hi there, > > On Tue, Dec 06, 2011 at 05:00:24PM +0200, Teemu Suikki wrote: >> Hi! >> >> I need a mp3 audio stream of live tv channels..

I did something similar once (relaying Internet radio stations to the local network in order to save outbound bandwidth with many users in parallel), and ran into trouble because the buffered nature of a fifo/pipe made audio skip every few seconds (tried with both ffmpeg and mplayer initially and also tried using an unbuffered pipe as a means of IPC, but in the end, neither worked and I had to look elsewhere). I settled for a solution involving Icecast as the streaming server, and a stripped down, cli-only custom build of VideoLAN Client (VLC) as its source. VLC comes with an optional Icecast output plugin you can enable at build-time that allows you to recode the incoming data on the fly, and relay it to Icecast in another format (OGG Vorbis or MP3, iirc). I'm pretty sure you should be able to do that with a video input as your source, too. -- with best regards: - Johannes Truschnigg ( johan...@truschnigg.info ) www: http://johannes.truschnigg.info/ phone: +43 650 2 17 xmpp: johan...@truschnigg.info Please do not bother me with HTML-eMail or attachments.

[vdr] Streamdev script to stream audio only?
Hi! I need a mp3 audio stream of live tv channels.. I tried to do it with ffmpeg, but it doesn't work properly. No data is transferred, I guess ffmpeg doesn't like to write to a fifo? Any ideas? ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
