Status: RESOLVED DUPLICATE of bug 455165

(Core :: Audio/Video, defect)

Description

This affects Icecast live streaming primarily. When the stream serial changes (eg. due to a metadata update) Firefox stops playing the stream.

Reproducible: Always

Steps to Reproduce:
Try to listen to a live (or saved) audio stream produced by Icecast2/Ices2.
Actual Results:  
Audio playback stops when the metadata changes (the stream serial changes).

Expected Results:  
FireFox should have continued playing until the end of data, not stopped at the end of the logical stream.

Thanks for the report.  Unfortunately the high level library we're using to deal with Ogg doesn't support chained streams yet.  We've got a bug on file, so I'll dupe this to that.
