Dear all

Please teach the way to encode with h264 lossless mode.

According to the UMC manual, the following parameters are related.

  •     profile_idc = HIGH444 (244?)
  •     rate_controls.method = H264_RCM_QUANT? (Constant quantization parameters)
  •     rate_controls.quantI = quantP = quantB = - 6 * (bit_depth_luma - 8)
  •     qpprime_y_zero_transform_bypass_flag = true

Anything else?

I tried the above parameters, but lossless mode didn't work. (near lossless mode?)

I've tried with IPP 7.0.

Thanks.
