from Boyuan Zhang
Hi Andy, To summarise your test results, basically you saw the following 3 issues with CQP, is it correct? - Issue #1. For large clip, sometime you can "invalid GstVaapiCodedBuffer size (0 bytes)" error. - Issue #2. Random corruption observed when using CQP. Corruption issue is gone after disable the statement "if (context->desc.h264enc.rate_ctrl.rate_ctrl_method !=PIPE_H264_ENC_RATE_CONTROL_METHOD_DISABLE" - Issue #3. Encoding speed is twice faster when setting QP<=28 So far I'm lucky enough that my test haven't trigger any of the issue yet. I will spend more time to try from my side. Again, if you could share the commands you were using to trigger the above 3 issue, that would be very appreciated. In the meantime, I would like to push the 2 patches to upstream first. Because this two patches don't change the behaviour of CQP, but only fixing VBR/CBR. Therefore, I believe CQP fix should be apart from these 2 patches. Regards, Boyuan
