* Initial nvdec implementation using FFmpeg * Fix swapped channels on the video decoder and the G8R8 texture format * Fix texture samplers not being set properly (regression) * Rebased * Remove unused code introduced on the rebase * Add support for RGBA8 output format on the video image composer * Correct spacing * Some fixes for rebase and other tweaks * Allow size mismatch on frame copy * Get rid of GetHostAddress calls on VDec
