OpenVisualCloud / SVT-HEVC

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.

Hi @daijh , I tried on that commit. No crash. Is it content related?

I use gcc 9, not sure if relevant. gcc version 9.2.1 20191102 (Ubuntu 9.2.1-17ubuntu1~18.04.1)

Let me switch back to default gcc and retry with last code on master.

If restore default gcc7 and with master code. Issue not reproduced. Close it.
