Dynamic change bitrate

  when I use " Intel MediaSDK 2022Q3 Release - 22.5.4" at 11th Gen Intel(R) Core(TM) i7-1165G7.**


use h264 encode, 720p5994,BufferSizeInKB set to 3500 at init, when I change bitrate from 27Mbps -> 32Mbps . m_pmfxENC->Reset faild, ret=-14 or ret=5. hevc don't have this issue.

Q1: Is there any way to avoid this error(ret=-14/ret = 5)?

when encode ret=-14 or ret=5, sometimes will cause sample_decode return -14(MFX_ERR_INCOMPATIBLE_VIDEO_PARAM).

 
 

I have add use LD_PRELOAD=/opt/intel/mediasdk/lib64/libmfx-tracer.so.1.35 to catch the debug log, please see at the attachment. you can search MFX_WRN_INCOMPATIBLE_VIDEO_PARAM.

I also meet this issue when use ONE VPL at 12th Gen Intel(R) Core(TM) i7-12700.
