Description Thiago Sousa Santos 2009-08-12 21:14:11 UTC
asfmux might mess up sinkpads when it writes indexes because it sorts the GstCollectData list in GstCollectPads (because the spec wants video pads in stream number order). While developing it I assumed the g_slist_reverse would create a new list, but it doesn't.

As a result, some of the GstCollectData might be lost and the muxer will use only the remaining ones to compute media duration and other fields.

The solution is to copy the list and then reverse it.

asfmux: Do not mess up GstCollectData list

asfmux was messing up with the GstCollectData list of its
GstCollectPads when sorting the list inplace. This patch makes
it copy the list before sorting it, leaving the GstCollectPads
list as is. Fixes #591610
