We'll leave it to the ffserver maintainer to fix this after merge.

I cannot test ffserver (or even build for some dependecy reason), but does this help? http://pastebin.com/DCMgH0Va

segfault is fixed but it seems not to work

I don't know how it works at all, so not sure about that, but if it fixes the crash I'm going to apply it at least. Streams should have a valid codecpar.

Fixed,
