Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Media Player has very poor quality on Mac

We're having a nasty issue with the Media Player framework on Mac: MP4 videos look heavily compressed and much darker. We're fairly positive the issue is directly with the Avf codec and a potential colorspace conversion (ie: blue shades turn directly to black). This is happening at least on two older Macs running High Sierra. Same videos on Windows work fine.

At first I thought Media Textures could be the problem, but the video looks wrong directly when played through the Media Player. Please look at the attachments — the differences are very noticeable in fullscreen, especially in dark areas, and this is ruining the game experience for our Mac users.

We've been experiencing this issue since 4.20 and the problem persists with 4.21.1. Any Mac developers who can share their experience? Perhaps a quick and dirty workaround? I'm not afraid of experimenting with the source code, but I'm not sure where to begin looking.

Many thanks in advance!
