Changes since V1:
* Implemented fixes suggested by Moritz Barsnick (if/else whitespace)
* Strict checking on overread of the IP packet data
* Fixed checking the size of the IP packet header size (6 vs 8)
Changes since V2:
* Correct the header size check found by Paul B Mahol
This patch series implement the previously unknown opcodes 0x06, 0x0E,
and 0x010 for Interplay MVE movies.
With this series every MVE sample[0] plays correctly, but I have some
doubts as to the implementation of the extra two AVFrames necessary for
format 0x10. If someone has a better idea on how to achieve this I'll
happily rework it as necessary.
I've tried to split up the patchset logically, I hope this makes sense.
I'm working with Multimedia Mike to get detailed information on the frame
formats added to multimedia.cx
If preferred the patchset is also available on github[1]

[PATCH v2 1/5] Interplay MVE: Implement MVE SEND_BUFFER operation
This patch implements a feature that wasn't used for 0x11 formatted movies.
See the commit message for details.
[PATCH v2 2/5] Interplay MVE: Refactor IP packet format
This patch changes the IP packet format for interplaymovie. The reason for
this is that frame format 0x10 requires an extra stream of data for a total
of three to work correctly. This generalizes that for all frame formats.
