Comment 14 for bug 1530229

Hi, Tim.

Besides the (yet to be addressed) problem from bug 30557, GStreamer use in wine is contained in dlls/winegstreamer/, with pretty much all but header includes constrained to the two files, those touched by my failed patch: dlls/winegstreamer/gstdemux.c and dlls/winegstreamer/gsttffilter.c.

While the doc situation has improved a little bit since the time I whined about it on IRC, there's still very little live code examples of allocation queries, mostly due to most gstreamer code redirecting the issue to handlers in abstract plugins (well, base classes, if you want to get technical).

While at this time there *is* a section in http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/section-allocation-query.html about it (as opposed to a TODO placeholder back when I was taking my shot), it still addresses it from video_buffer angle, while current gstreamer code in wine is for audio too. (would be nice if something could be done about bug 9127 too)

On a not really related note: kind of sorry, that I didn't pursue https://bugzilla.gnome.org/show_bug.cgi?id=734451 to its conclusion, but I though it'd be better to leave implementation details to you. While that problem affected people building gst-{ffmpeg,libav} against ffmpeg, while you (i.e. upstream) picked libav side of that silliness, it still would make the code more future proof, if - for example - libav decided to pick up one of (the admittedly few) codecs that have period or comma in its library name.
