    This is libaacplus2.0.2/autogen.sh， It was edited, just let it create configure file :

    #!/bin/sh
    
# Run this to set up the build system: configure, makefiles, etc.

  • Modifying motion vectors in ffmpeg H.264 decoder

    14 février 2012, par qontranami

    For research purposes, I am trying to modify H.264 motion vectors (MVs) for each P- and B-frame prior to motion compensation during the decoding process. I am using FFmpeg for this purpose. An example of a modification is replacing each MV with its original spatial neighbors and then using the resultant MVs for motion compensation, rather than the original ones. Please direct me appropriately.

    So far, I have been able to do a simple modification of MVs in the file /libavcodec/h264_cavlc.c. In the function, ff_h264_decode_mb_cavlc(), modifying the mx and my variables, for instance, by increasing their values modifies the MVs used during decoding.

    For example, as shown below, the mx and my values are increased by 50, thus lengthening the MVs used in the decoder.

    mx += get_se_golomb(&s->gb)+50;
    
my += get_se_golomb(&s->gb)+50;

    However, in this regard, I don't know how to access the neighbors of mx and my for my spatial mean analysis that I mentioned in the first paragraph. I believe that the key to doing so lies in manipulating the array, mv_cache.

    Another experiment that I performed was in the file, libavcodec/error_resilience.c. Based on the guess_mv() function, I created a new function, mean_mv() that is executed in ff_er_frame_end() within the first if-statement. That first if-statement exits the function ff_er_frame_end() if one of the conditions is a zero error-count (s->error_count == 0). However, I decided to insert my mean_mv() function at this point so that is always executed when there is a zero error-count. This experiment somewhat yielded the results I wanted as I could start seeing artifacts in the top portions of the video but they were restricted just to the upper-right corner. I'm guessing that my inserted function is not being completed so as to meet playback deadlines or something.

    Below is the modified if-statement. The only addition is my function, mean_mv(s).

    if(!s->error_recognition || s->error_count==0 || s->avctx->lowres ||
    
       s->avctx->hwaccel ||
    
       s->avctx->codec->capabilities&CODEC_CAP_HWACCEL_VDPAU ||
    
       s->picture_structure != PICT_FRAME || // we dont support ER of field pictures yet, though it should not crash if enabled
    
       s->error_count==3*s->mb_width*(s->avctx->skip_top + s->avctx->skip_bottom)) {
    
        //av_log(s->avctx, AV_LOG_DEBUG, "ff_er_frame_end in er.c\n"); //KG
    
        if(s->pict_type==AV_PICTURE_TYPE_P)
    
            mean_mv(s);
    
        return;

    And here's the mean_mv() function I created based on guess_mv().

    static void mean_mv(MpegEncContext *s){
    
    //uint8_t fixed[s->mb_stride * s->mb_height];
    
    //const int mb_stride = s->mb_stride;
    
    const int mb_width = s->mb_width;
    
    const int mb_height= s->mb_height;
    
    int mb_x, mb_y, mot_step, mot_stride;
    

    
    //av_log(s->avctx, AV_LOG_DEBUG, "mean_mv\n"); //KG
    

    
    set_mv_strides(s, &mot_step, &mot_stride);
    

    
    for(mb_y=0; mb_ymb_height; mb_y++){
    
        for(mb_x=0; mb_xmb_width; mb_x++){
    
            const int mb_xy= mb_x + mb_y*s->mb_stride;
    
            const int mot_index= (mb_x + mb_y*mot_stride) * mot_step;
    
            int mv_predictor[4][2]={{0}};
    
            int ref[4]={0};
    
            int pred_count=0;
    
            int m, n;
    

    
            if(IS_INTRA(s->current_picture.f.mb_type[mb_xy])) continue;
    
            //if(!(s->error_status_table[mb_xy]&MV_ERROR)){
    
            //if (1){
    
            if(mb_x>0){
    
                mv_predictor[pred_count][0]= s->current_picture.f.motion_val[0][mot_index - mot_step][0];
    
                mv_predictor[pred_count][1]= s->current_picture.f.motion_val[0][mot_index - mot_step][1];

    }
    
}

    I would really appreciate some assistance on how to go about this properly.
