Flac files that will playback but not stream

[stuart68]

Hi,

This message was originally posted on the Nabble mailing lists, but I can now provide more information.

To re-cap I have flac files that I can playback using playbin2 uri=file:///   ,  but when I try to stream these files using  playbin2 uri=http://  I get the following error:

ERROR: from element /GstPlayBin2:playbin20/

GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source: Internal data flow error.
Additional debug info:
gstbasesrc.c(2507): gst_base_src_loop (): /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source:
streaming task paused, reason error (-5)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...

This is using Ubuntu 10.04, with lighttpd as the web server.

On the same machine I have a load of other flac files that all stream perfectly.


I was asked to increase the debug level and provide all of the output, I have included the area that I think is important and attached the file.

One of the offending flac files is also attached.

Although the issue is evident on my Ubuntu machine, I really want this to work on an arm embedded system.

If I need to report this as a bug please tell me how I should do that. Also where can I upload the flac file to?

Thanks,
Stuart

Hi,

I'm sorry for the late reply, but time available for open hacking is
nowadays << than the needed ;).

So my first though is that either the file is corrupted or it's not in
the proper folder where lighttpd is assumed to search for it.
Obviously, I don't have any empirical grounds to base my assertion
onto ;).

Unfortunately, souphttpsrc appears not to use SoupLogger
(http://library.gnome.org/devel/libsoup/stable/SoupLogger.html). In
the past I've been debugging http-related issues by manually adding
the logging stuff (should be pretty simpler, something like
soup_logger_new, soup_logger_attach and an handler) and
recompiling/running the test with the brand new logging.

OT: I never really understood why the logger is not configured
depending on the verbosity of GST_DBUG for the element.. is it the
case to file a bug?

Unfortunately, I could not find the file in the attachments. Maybe it
has been filtered out by the list...

Bugs against GStreamer are filed in Gnome Bugzilla (search for
Desktop/GStreamer component). Please attach both a working file and a
broken one (possibly both short in length).

That sounds useful. A patch would be great.

Hi all,

playing with the souphttpsrc I noticed that it's already pretty
verbose, at least in case of error. Maybe it would be possible to
improve the outgoing messages info with the logger approach but, at
lest in Stuart's scope, it should be enough to run the test with a
pretty recent version of gst-plugins-good and GST_DEBUG=souphttpsrc:5

10.4 doesn't exactly have the most recent versions. Could you try with
the more up-to-date GStreamer packages from the GStreamer PPA for
ubuntu, to see if it still happens with -good 0.10.27?

If yes, could you please file a bug in bugzilla, see
http://gstreamer.freedesktop.org/bugs/ ?

Could you check if the problem also happens with just the beginning of
the file? (head --bytes=990k foo.flac > head.flac) If yes, please attach
the beginning to the bug report as well, thanks!

 Cheers
  -Tim

Hi Tim,

I tried this with only the head of the flac file as you suggested and it is no different.

My target operating system is embedded Linux running on an arm9 processor. Gstreamer versions are as follows:

gst-ffmpeg-0.10.11-r0
gst-plugins-bad-0.10.20-r11
gst-plugins-base-0.10.31-r11
gst-plugins-good-0.10.26-r11
gst-plugins-ugly-0.10.16-r11

Other flac files stream perfectly.

The information regarding Ubuntu was to highlight the fact that I have tried other OS'es, I will update this post with findings re Ubuntu.

Thanks,
Stuart

plugins bad failed to update, but for flac I do not think this has an impact.

Repeating my test results in exactly the same error, the file will not stream.

If the head of the head of the flac file looks reasonable, then I will submit a bug.

Thanks,
Stuart
