[matroskademux] error message for unrecognised FOURCC codes should be improved

mathrick@hatsumi:~/Skrivebord$ gst-launch-0.10 -v playbin uri=file://$HOME/Skrivebord/\[pem\]_Bakemonogatari_15-full.mkv [...] ** Message: don't know how to handle video/x-unknown, codec-id=(string)V_MS/VFW/FOURCC I don't know if that's playbin's fault or something else's, but the message should definitely mention _what_ FOURCC wasn't recognised; video/x-unknown is rather useless.
I'm somewhat tempted to just WONTFIX this, since it's utterly pointless to mention the fourcc here (it's not an error message; and any proper error message will never ever mention a FOURCC; using GST_DEBUG=*:2 will show you this already; 99.9% of the people only care about the video playing or not and not the exact reasons why; mentioning the unmapped fourcc in your bug report doesn't really make a huge difference to us). But anyway, I'll see what I can do..
In the case of the V_MS/VFW/FOURCC matroska mapping you could simply add a fourcc field to the caps
Sorry for the delay, thought I'd pushed this ages ago: commit d73440cb976d8b2ae51f231f19c10d7eaddb6074 Author: Tim-Philipp Müller <tim.muller@collabora.co.uk> Date: Thu Jul 1 00:22:07 2010 +0100 matroska-demux: put unrecognised RIFF format IDs into the unknown caps Extra info can't hurt. Field names aren't necessarily consistent with what's used elsewhere though (e.g. avidemux), but then neither are the caps. https://bugzilla.gnome.org/show_bug.cgi?id=623178
