streaming mp3 to Icecast server: av_interleaved_write_frame(): Broken pipe

PATRICK KEROULAS
Hello,

Our CDN provides icecast endpoints for mp3 streaming. As they recommended,
I used '-legacy_icecast 1' to be compatible with old Icecast version
which uses the SOURCE method instead of PUT.

Transcoding to a file works fine but there is something wrong with
the endpoint at the http/authentication level. From the error
'av_interleaved_write_frame(): Broken pipe', I'm not able to determine
whether the client or the server is responsible for that.
Can anyone help? Thanks.

Regards,

Patrick

Broken pipe errors usually happens when the servers refuses or closes the
connection for some reason, you'll should check if there's no parameter
strange to the server like metadata or audio sample rate (try to resample
to 44100 hz for instance)

PS: beware of the "authentication basic" headers published here, they are
the user and password base64 encoded and easily decoded by anyone which
read this message

Using Wireshark monitoring the traffic the connections seams to be ok on
Icecast 1 protocol, using SOURCE method and such. I saw that your ffmpeg
version is quite old, updating can solve any bug that can be messing out
your usage

I've tried adding " -content_type 'audio/mpeg' -ice_name 'CBC'
-ice_description 'CBC' " to make the Icecast request more complete, I don't
know if they are mandatory to Limelight but they get rid of "It seems you
are streaming an unsupported format." warnings on the ffmpeg log

Have you considered using a modern version of ffmpeg?  That version is
considered ancient.

I provided a network trace to the provider and it turned out they had
a config issue on their end. It's working now.

Thank you all,

PK
