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

2011-12-07 Thread Füley István

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:

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?

Hi, i need transcoding, the DVB stream is 224kbps mp2 which is too
high bitrate for mobile use..

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.

2011-12-06 Thread Teemu Suikki
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..
