SVT HEVC encoder. Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® processors. Using the open source SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel® Xeon® processors to achieve a real advantage of processing efficiency.
When I use FFmpeg SVT-HEVC for stress test, there will be some channels "Conversion failed".
Reduce to 40 channels will be OK.
