xmedia recode subtitles forced mediainfo still no

When using animated subtitles, using sub picture buffering is the only way I can get smooth playback, setting it to 0 makes playback horribly stuttery due to crazy frame dropping during animation, even though I have CPU cycles to spare. I think one of their chief argument was that KMP is written in Delphi, not C, hence there is no chance of there being copied code from MPC, and KMP only links against Gabest's filters, hence it isn't violation of GPL. I fully understand the need for supporting Windows XP, as it's still an officially supported OS.Īt least on the allocator-presenter parts it seems to be okay, as the blending stage for main video, subtitles, OSD and the stats screen is clean and efficient for what I've seen in the code of EVR CP, Sync and VMR-9 (renderless).

(DirectX 9 lacks a lot font rendering technology.) That does involve quite a lot of work to get both hardware-level rendering (for DirectX 10 or newer generation GPU's) and software rendering paths working. A true upgrade would be to move to DirectX 10/11 native font rendering and composing.

It's still a bit hard to get it working, but at least I've disabled mipmap generation for some parts (still in testing phase). I've been trying to get it corrected, so it can use 8-bit RGBA instead of 4-bit RGBA, handle multithreading better and use a cleaner composing method.

The reason of the slow subtitle renderer is mainly because of the font handling.
