D1751, remove this library since its quite a specific - only supports an older version of this codec.
Also ffmpeg has added support for recent versions of the codec.
ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.

I/O

Scene Render Views
* Ability to have an arbitrary number of views in the scene
Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

Issue was caused by _wstat returning EOVERFLOW error because
of file size didn't fit into stat structure which was using
long datatype.
The idea of this patch is to use _wstat64 and _stat64 structure
which is capable storing 64bit file sizes.
Made it a typedef for stat structure used by BLI_stat function
in order to make code easier to follow and avoid ifdefs all
over the place.
Additionally solved issue with BLI_exists which was wrongly
returning False in cases destination file is larger then 4GB.
don't use extension checking preference for low level loading functions,
otherwise a user preference may impact a script loading a file for example.
looked into making this an argument and passing it in, but theres no
real advantage and its simpler just to remove.
CHANGE: writing an animation in the ogg movie format now defaults to .ogv (ogg/video) which is recommended by Xiph.org for video
CHANGE: for .ogg files a check is added whether Blender can read it as a movie (is avi or ffmpeg movie), otherwise assume audio
CHANGE: the anim player now filters for the same extensions as the file browser
We now support the combined layer of Photoshop files (stored as layer 0
in the file). This way users can keep their files as multilayer PSD and
Blender always handle them as flat images.
For perfect alpha this requires an OpenImageIO update:
342cc2633f
Photoshop sample files:
https://github.com/OpenImageIO/oiio-images
Brecht has some pending fixes to push for OIIO as well, so we may as
well wait to update our libraries.
What works:
===========
* 8bit images (with or without alpha)
* 16bits images (alpha discarded)
* Photoshop files saved with 'Maximum Compatibility'
* Cycles, Blender internal, BGE (and player)
Known limitations
(due to OIIO dependency):
=========================
* Images with less than 4 channels show a wrong thumbnail (bug may be in OIIO)
* Packed images are not supported
* We do not write PSD files.
Note: old Blenders have support for PSD via Quicktime library. But due
to license issues this was discontinued.
Many thanks for Brecht van Lommel for reviewing the patch, suggesting
multiple improvements and to help solving the alpha issue.
- reading bmp images was failing (needed to increase the size of the header to 64 bytes)
- the dnd image was being incorrectly checked (was always returning true even when none was used).
Animplayer treated .tif extensions as movie files, so that didn't work.
Added another hardcoded check for it, like for png tga exr jpg etc.
Why FFmpeg thinks .tif is a movie... that's for another day :)
Quicktime QTKit did same btw.
Patch makes it possible to compile blender with recent ffmpeg
and libav libraries, mainly by getting rid of deprecated API.
Original patch by Campbell Barton with own modifications to
support compilation with older ffmpeg versions.
This patch could break compatibility of FFV1 videos playing
back in older players, mainly because of alpha support changes.
Preserving compatibility with such players became a headache
and think it's high time to get rid of workarounds here.
- Add check for header field in BMP decoder. This is needed to distinguish
whether file is indeed BMP image or not.
Without this check Blender could easily crash when it'll try to load
non-BMP image.
Tested with files from own HDD, but all of them has got BM header field,
more testing would be welcome.
- Made Jpeg2000 aware of J2K codec. Originally was needed to verify .j2c
files here in the studio, but having support of this codec would be
nice in general.
Currently supports only reading in this codec, writing would still
using jp2 codec.
- Make FFmpeg initialization called from creator, not from functions
which requires FFmpeg. Makes it easier to follow when initialization
should happen.
- Enable DNxHD codec. It was commented a while ago due to some strange
behavior on some platforms. Re-tested it on Linux and Windows and
it seemd to be working quite nice. Would let it be tested further,
if it wouldn't be stable enough, easy to comment it again.
- Make non-error messages from writeffmpeg.c printed only if ffmpeg
debug argument was passed to blender. Reduces console pollution
with messages which are not useful for general troubleshooting.
Error messages would still be printed to the console.
- Show FFmpeg error message when video stream failed to allocate.
makes it easier to understand what exactly is wrong from Blender
interface, no need to restart blender with FFmpeg debug flag and
check for console messages.
Used custom log callback for this which stores last error message
in static variable. This is not thread safe, but with current
design FFmpeg routines could not be called form several threads
anyway, so think it's fine solution/
This switches some areas of Blender which are related on FFmpeg stuff
from deprecated symbols to currently supported one.
Pretty straightforward changes based on documentation of FFmpeg's
API which symbols should be now used.
This should make Blender compatible with recent FFmpeg 0.11.
Should be no functional changes.
Thanks Lockal for finding faulty stat function which helped a lot.
Now there BLI_stat. I will replace all other stat later.
*** Please use BLI_xxxx() functions ***
for file operations
