* subs, vo_vdpau: support RGBA color for PGS subtitlesUoti Urpala2012-09-181-2/+6
| | | | | | | | | | | | | | | | | | | | | | Support passing bitmap subtitles to VOs in full RGBA color, and implement this for libavcodec-decoded subtitle formats on decoding side and vo_vdpau on display side. Currently this is enabled for PGS (blu-ray) and DVB subtitles. VDPAU seems to have sampling issues similar to known GL ones when drawing a sub-rectangle from a larger texture with scaling, where adjacent pixels outside the specified source rectangle affect the result. As the bitmap subtitles may be scaled, add padding support to the bitmap packer code. In principle, this could be used for colored DVD subtitles too. However, the libavcodec DVD decoder lacks parts of the resolution and palette handling that are present in spudec.c. Conflicts: libvo/vo_gl.c sub/dec_sub.h sub/sd_lavc.c
* vo_vdpau: split bitmap packing code into a separate fileUoti Urpala2012-09-181-0/+47
Split the vo_vdpau code that calculates how to pack all subtitle bitmaps into a larger surface into a separate file. This will allow using it in other VOs. Conflicts: Makefile libvo/vo_vdpau.c Note: this commit does the same as an earlier commit by me (4010dd0b1a27e3996). My commit added the vo_vdpau packer code as eosd_packer.c, while this commit by uau uses bitmap_packer.c. Since bitmap_packer.c has a different interface, and because there are more commits changing OSD rendering coming, I will pick uau's version. However, vo_gl, vo_gl3 and vo_direct3d are still using eosd_packer.c, so to make the transition easier, don't delete eosd_packer.c yet.
