Humm, Like I said I could only replicate the problem with 16.04.
In any case, while fixing guvcview for 16.04 I squashed a couple of bugs that
could, at least in one case and under certain conditions, cause mpeg4 encoding
to fail.
This is fixed in the latest build from my testing ppa:
Ok, so this problem comes from a change in the newest ffmpeg
(libavcodec) API, the default 15.10 version should work fine with the
stable guvcview version. But if you upgrade libavcodec (via ppa or by
building the source code) you need to rebuild guvcview (using the latest
git code).
The upcoming
Well I still need the original file, otherwise I can't check what's wrong with
it.
I've tested this in 15.10 and the generated files were playable without issues.
It could be related to the video codec, but I really need to check the file, to
make sure.

Paulo

If this was supported before then I think it may be an extension control and

Attempt to record video as MKV file causes guvcview crash
uvcvideo changes between 2.6.32 and 2.6.35 were not causing the error with
dynamic controls, I've clean up the installation and now everything seems to be
working again, even with the old uvcvideo.h.
Something else was causing the control mappings to fail.

Public bug reported:
This package is mostly important to add extension controls to uvc logitech
cameras ( focus, pan/tilt, Led control, ...)
But for this to happen it needs to be compiled with the matching kernel
