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
