Hoi all,
I've posted a bug about this:
http://bugzilla.gnome.org/show_bug.cgi?id=578926but before starting on a fix I need some advice.
I repeat the problem: when streaming MPEG4 from an IP camera over http,
decodebin(2) doesn't insert an mpeg4videoparse element in the pipeline, which
results in faulty decoding (by ffdec_mpeg4).
I'm prepared to fix this, but I need some input about what would be the best
solution:
1. don't fix it - application should insert mpeg4videoparse;
2. modify typefind and ffdec_mpeg4 (any others?) so they have
parsed=(boolean)... in their caps;
3. increase rank of mpeg4videoparse, and modify decodebin2 so it will not
chain multiple mpeg4videoparse elements;
4. do parsing in ffdec_mpeg4;
5. something else still.
Option 2 seems to be the simplest to implement, but may affect other mpeg4
elements that I don't know about. It could also be considered an API change.
Option 3 is the most generic (applies to other codecs too, and could be used
to autoplug convertors, perhaps).
Regards,
Arnout
