[PATCH 0/4] MR8183: mf: Read byte streams in chunks of 256KiB.

[Charlotte Pabst (＠CharlottePabst)]

I'm dealing with a game that relies on this constant.

Tagging @rbernon since this is using a proton commit of his.

Tests should be run both with HKCU\Software\Wine\MediaFoundation\DisableGstByteStreamHandler enabled and disabled.
