Re: [linux-uvc-devel] Logitech C920 dropped/duplicated frames / decreasing timestamp problem (h.264)

[Rucio D. <sf-...@un...>]

Hello Oleksij, I'm afraid that is somewhat over my head as I do not
understand the format entirely. I am able to compile and try code changes,
do you think it would be advantageous to place some debug output in the
parts that are processing the stream from USB or handling them in
uvcvideo.c?

Also, my apologies for having the incorrect file share settings on all of
the files (not familiar with Google Drive), I have corrected this. Here is
the direct link to the folder containing all three video files.

Thanks,
Rucio
