说明

ffmpeg 分层录制一直都有瓶颈，更好的硬件带来的录制速度提升很有限，所以有的时候用obs录屏效率会高很多，现在官方放出了测试版本，替换原安装目录下的 AfxHookSource.dll 后进入游戏便可测试录制相关情况，欢迎积极参与测试反馈意见

branch: https://github.com/advancedfx/advancedfx/tree/faster-recording-295
commit: https://github.com/advancedfx/advancedfx/commit/d15e263c8130652e030e92e6738f5377eb518bab
current compile: AfxHookSource_20220106T1317Z.zip

improvements already implemented:

remove format conversions not required for FFMPEG
prevent bottle-necking on the drawing thread, while we could at least use multiple threads for required post-processing
output multiple files ("lanes") at once from multiple threads
also increase FFMPEG pipe buffer to 1 MB per stream

planned improvements (not implemented yet!):

Solve HLAE wasting a frame when recording even when it shouldn't
Mutli threaded sampling system support

breaking changes:

if you used vflip video filter in custom FFMPEG settings, you probably need to remove it!

Testing

If you only have time / motivation to test a subset of the tests, that's ok too.
Please report bugs that you find (even in combinations not coverred by these tests)!

Each test should be done with and without MSAA and otherwise same settings.
Each test should be done with stable public version and the current compile above

A: Single stream performance

Add a only normal stream: mirv_streams add normal norm
mirv_streams settings edit afxDefault settings afxFfmpeg (if you want to use an otherpresets that's ok, but please report you did so)
Record start + record end to make the FFMPEG binaries hot
measure start + recordstart, record end + measure end
report number of frames recorded recorded (output FPS * output time recorded)

B: Multi stream performance

exec afx/updateWorkaround to add a default set of streams
mirv_streams settings edit afxDefault settings afxFfmpeg (if you want to use an otherpresets that's ok, but please report you did so)
Record start + record end to make the FFMPEG binaries hot
measure start + recordstart, record end + measure end
report number of frames recorded recorded (output FPS *output time recorded)
