[Libav-user] prores encoding

I'm having trouble with both prores codecs -- prores, and proes_ks.
I've tried both and even though both support FF_THREAD_FRAME I'm getting
significant frame tearing given the more threads I use.
vctx_->profile = 3;
vctx_->thread_type = FF_THREAD_FRAME;
vctx_->thread_count = 16;
to achieve reasonable performance, but the video tearing on output is not
good. Allot of frame jumping in addition.
Is this a known issue or is there a workaround? Or am I stuck to single
Google turned up nothing recent.
Or is it possible I'm doing something wrong with how I'm feeding frames?
I'm using the standard avcodec_send_frame/avcodec_receive_packet setup.
Using ffmpeg 3.4.2 libs.
