Comment (by llogan):

 This is the current state. I'll quote another developer, wm4:

 > FFmpeg is a project by volunteers and open source enthusiasts (with some
 people being paid for implementing specific features or fixing specific
 bugs), so there is no planning, no roadmaps, no project management, no
 predictable behavior, no guarantees, and no official responses of any

 I didn't investigate this, but I'm going to assume here that the file is
 at fault. It is not possible to (and we shouldn't) support every broken
 format from every broken encoder. Supporting each encountered oddball
 proprietary variant increases the maintenance burden, code churn,
 log/mailing list/bug tracker noise, possible security issues, wastes
 developers' time, and puts the expectation on FFmpeg to always decode
 absolutely everything instead of users demanding that manufacturers
 provide usable, standard outputs.

 Since contacting Cisco is likely a waste of time your best bet may be to
 provide a patch that fixes your issue, but I know that this is not a
 realistic suggestion for the average user.

 Offering a financial bounty may increase the chances of this getting
 someone's attention who may find it interesting enough to implement a
 workaround, but it is not guaranteed.
