[FFmpeg-user] 10-bit color x11grab

[amindfv at mailbox.org]

In the spirit of "patches welcome" I've tried to fix this on my own. Patch attached.

Currently I'm hitting this error:

    Error while decoding stream #0:0: Invalid argument
    [rawvideo @ 0x55b961f49180] Invalid buffer size, packet size 3145728 < expected frame_size 4718592

I'd appreciate any help!

> [x11grab @ 0x5574a7e12140] Mapping this pixmap format is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.
