Hi, I am trying to encode to dnxhd with libavcodec. The result is quite glitchy with stuttering and anomalies on most frames.
During encoding I see the following message almost continuously. > Internal error, put_bits buffer too small I have tried to understand what this buffer is, how it is set up and I am struggling. From what I can understand the puts_bit buffer is DNXHDEncContext->m->pb which is initialised via init_put_bits() in dnxhd_encode_thread(). The 2 arguments used in init_put_bits() are DNXHDEncContext->slice_offs and DNXHDEncContext->slice_size. These 2 are configured in dnxhd_setup_thread_slices() with 2 variables MpegEncContext->mb_width and MpegEncContext->mb_bits. If my understanding is correct the 2 aforementioned variables in MpegEncContext are the variables I need to set. However, I have no idea what they mean or how they are accessed outside of AVCodecContext->priv_data. Is my understanding correct? How does one setup the puts_bit buffer correctly for a dnxhd encode? Kind regards Jon Noble
