Did you execute git submodule update --init --recursive to get rc\openh264?
And you can modify BuildWindows.ps1 to use VS 2022.
Thanks.

[jzp-oos]

@jzp-oos 你执行了rc\openh264吗？您可以修改BuildWindows.ps1以使用VS 2022。 谢谢。git submodule update --init --recursive

解决了

请问支持多线程解码吗 开多个线程解码cpu满了

请问支持多线程解码吗 开多个线程解码cpu满了
Does it support multi-threaded decoding? Open multiple threads to decode and the cpu is full

I don't know because it depends on implementation of openh264 libs.
But it could be 'no'.
Because openh264 repo says (https://github.com/cisco/openh264#encoder-features) that encoder support multi threads but decoder does not say anything.

DecodingParam里CpuLoad EcActiveIdc这2个参数有何作用

DecodingParam里CpuLoad EcActiveIdc这2个参数有何作用
What are the functions of the two parameters CpuLoad EcActiveIdc in DecodingParam

There is no useful document for openh264 so we have to read source code.

CpuLoad
DecodingParam.CpuLoad corresponds to https://github.com/cisco/openh264/blob/fac04ceb3e966f613ed17e98178e9d690280bba6/codec/api/svc/codec_app_def.h#L606
And unit test program uses this parameter in https://github.com/cisco/openh264/blob/6584567029f8899d5375333228a77517ba0c2b3b/test/decoder/DecUT_DecExt.cpp#L90

I guess we may be able to control usage of cpu by passing but I'm not sure that parameter meaning.
