* video: initial Matroska 3D supportwm42014-08-301-0/+1
| | | | | | | | | | | | | | | | | | | | | This inserts an automatic conversion filter if a Matroska file is marked as 3D (StereoMode element). The basic idea is similar to video rotation and colorspace handling: the 3D mode is added as a property to the video params. Depending on this property, a video filter can be inserted. As of this commit, extending mp_image_params is actually completely unnecessary - but the idea is that it will make it easier to integrate with VOs supporting stereo 3D mogrification. Although vo_opengl does support some stereo rendering, it didn't support the mode my sample file used, so I'll leave that part for later. Not that most mappings from Matroska mode to vf_stereo3d mode are probably wrong, and some are missing. Assuming that Matroska modes, and vf_stereo3d in modes, and out modes are all the same might be an oversimplification - we'll see. See issue #1045.
* Parse::Matroska::Reader: get rid of `bigrat`Diogo Franco (Kovensky)2014-02-151-17/+20
| | | | | | | | | | | | | | | It seems that it was causing issues with certain perl setups (such as the one on issue #549). It also turns out that it was not behaving correctly (not all constants were being promoted to big nums as they should), so we use explicit objects to derive the constants. There were also precedence issues. I wonder if this even worked right to begin with. The 'double' path (8-byte floats) is untested, as I couldn't easily find a file with such a field. Closes #549.
* demux_mkv: support V_UNCOMPRESSED video trackswm42013-01-241-0/+1
| | | | | | Tested with a sample generated by: ffmpeg -i in.mkv -an -vcodec rawvideo out.mkv Also add proper dependencies for the Matroska Perl stuff in Makefile.
* Port several python scripts to PerlKovensky2012-11-085-0/+1171
file2string.pl and vdpau_functions.pl are direct ports. matroska.py was reimplemented as the Parse::Matroska module in CPAN, and matroska.pl was made a client of Parse::Matroska. A copy of Parse::Matroska is included in TOOLS/lib, and matroska.pl looks there first when trying to load the module. osxbundle.py was not ported since I have no means to verify it. Python is always available on OSX though, so there is no harm in removing the check for it on configure.
