Hi all,

New to all this streaming business so please be gentle

So I can set up a stream using a http stream as a source and outputing it to http on 8080 via the GUI.

What i can't figure out is how to do the same thing using the command line.

The gui gives me an output string of :

Code: Select all

:sout=#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=48000}:http{mux=ts,dst=:8080/} :sout-keep

and the input stream i use for example is :

Code: Select all

http://a.files.bbci.co.uk/media/live/manifesto/audio/simulcast/hls/uk/sbr_high/ak/bbc_radio_two.m3u8

so I've tried

Code: Select all

cvlc http://a.files.bbci.co.uk/media/live/manifesto/audio/simulcast/hls/uk/sbr_high/ak/bbc_radio_two.m3u8:sout=#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=48000}:http{mux=ts,dst=:8080/} :sout-keep

But that just throws a load of errors.

Can anyone point me in the right direction of what the correct format for cvlc would be ?

Thanks in advance for any help.

Did you try a space in front of :sout=#xxx ?

Thanks for the reply.

yes i tried it with a space and replacing the : with --.

I always get the following error(s)

Code: Select all

core stream output error: stream chain failed for `transcodesamplerate=48000:httpdst=:8080/'
[aba00510] core input error: cannot start stream output instance, aborting

missing "" around your sout option

Hi & thanks for the reply.

OK so i tried it with "" arround the sout's :

Code: Select all

cvlc http://a.files.bbci.co.uk/media/live/manifesto/dio/simulcast/hls/uk/sbr_high/ak/bbc_radio_two.m3u8 ":sout=#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=48000}:http{mux=ts,dst=:8081/}" ":sout-keep"

This now throws a whole load of errors :

Code: Select all

[08a37108] http access error: cannot connect to as-hls-uk-live.akamaized.net:80
[08a37108] access_mms access error: cannot connect to as-hls-uk-live.akamaized.net:80
[abc07970] core stream error: no suitable access module for `http://as-hls-uk-live.akamaized.net/pool_7/live/bbc_radio_two/bbc_radio_two.isml/bbc_radio_two-audio=320000-236119667.ts'
[abc07970] httplive stream error: downloading segment 236119667 from stream 0 failed

What is really frustrating is that this works perfectly and simply from the GUI - is their a command log that can be retrieved from the GUI to see what commands are actually being used ? or is that too easy

Cheers

Code: Select all

cvlc -vvv "http://a.files.bbci.co.uk/media/live/manifesto/dio/simulcast/hls/uk/sbr_high/ak/bbc_radio_two.m3u8" --sout="#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=48000}:http{mux=ts,dst=:8081/}" --sout-keep

Awesome, thanks very much.

Thanks for the help
