MMSH stream fails to pre-roll

Jonathan Miles-2
I'm having trouble getting the following internet radio stream to play using GStreamer 1.10:

gst-launch-1.0 playbin uri="mmsh://radio.yerevannights.com/YerevanNights?MSWMExt=.asf"

This gets to PREROLLING, but never any further.

With GST_DEBUG="asfdemux:6" I can see that packets are being received: http://pastebin.ca/3737122

The stream plays happily enough in vlc or mplayer.

Are there any asf/mms experts out there that can help?

Thanks,

Jonathan

Perhaps a redirection is occuring. Check for ELEMENT messages in the bus with a "redirect" structure. Starting with 1.10, there is a dedicated REDIRECT message, but it is not being used by mmssrc yet.

I can't see any redirect message (assuming below is the correct way of looking for it):

I also see the same problem on GStreamer 1.8.2.

Re: MMSH stream fails to pre-roll

Carlos Rafael Giani

This appears to be an asfdemux problem. This pipeline shows that there is no output from asfdemux:

gst-launch-1.0 -v mmssrc location=<a class="moz-txt-link-rfc2396E" href="mmsh://radio.yerevannights.com/YerevanNights?MSWMExt=.asf">"mmsh://radio.yerevannights.com/YerevanNights?MSWMExt=.asf" ! identity silent=false name=pre-asf ! asfdemux ! identity silent=false name=post-asf ! avdec_wmav2 ! audioconvert ! audioresample ! autoaudiosink

Interestingly, if I write the mmssrc output to a file, and then try to play that, it works.

Re: MMSH stream fails to pre-roll

Jonathan Miles-2
Thanks for the pointers, Carlos.

It looks like the problem is that there are five streams, only one of which contains any data, this means that gst_asf_demux_check_first_ts() never returns true, so none of the streams ever get activated. Even if I change the function to ignore the streams with no data, it still doesn't get past all_streams_prerolled().

When playing the mmssrc output from file, I think you get an EOS, which forces the data through, ignoring the checks (see gst_asf_demux_check_activate_streams()).

As the empty streams have a bitrate of 0, I'm guessing that the sensible thing to do would be to ignore these streams, but first I'll dig out the asf spec and see if I can gain any more enlightenment.
