H.264 encoder gives flickering output from SDK 1.18 version and above

Hi,

If the input to the encoder is fixed framerate, output is proper. If the input to encoder is variable framerate, output from the encoder is having flickering issue. Very old frames are repeated. This issue happens from Ver 1.18 onwards.

Is there any settings to be set done for changing the framerate dynamically

Hi Karthikeyan, sorry for delays with answer, is it related to VUI settings? from API 1.18 and possible some MSDK versions earlier was added mfxCodingOption2::FixedFrameRate option, designed to force fixed_frame_rate_flag in VUI, we'll check if there was regression related to encoding variable frame rate and get back to you, the same time, can you please check, if setting it to OFF can resolve your problem.

Hi Artem,

Thank you for the support.

It is working fine now after setting the "MFX_GPUCOPY_OFF" during init.

Thanks for update Karthikeyan, can you please share reproducer with us, we'll look why GPU copy causing those problems, it's not expected.
