[FFmpeg-devel] Replacement for AVCodecContext::directpred

[Saint Atique]

Hi,
Inside header file avcodec.h previously there was a declaration of
directpred as a member of structure AVCodecContext like this
    /**
     * direct MV prediction mode - 0 (none), 1 (spatial), 2 (temporal), 3
(auto)
     * - encoding: Set by user.
     * - decoding: unused
     */
    int directpred;

directpred has been removed later from ffmpeg.

I previously used directpred = 3 in my code. Now that I am planning to
upgrade ffmpeg library to the recent release for this windows application I
had to comment this line. However, it is giving slightly different output
for the encode function: avcodec_encode_video. Output video is worse in
quality and seems to be losing some information.

What is the replacement for directpred?

How can I make avcodec_encode_video encode just like before? I haven't
changed other parts of the code of the application except
replacing avcodec_alloc_context() with avcodec_alloc_context3()
and avcodec_open() with avcodec_open2() etc.

Can you please tell me how the member directpred affects the video encode
function and how it has changed over time and has been removed?

Regards.
