I think even better would be below + updating all decoders
the advanatge would be that applications would not need to be chnaged
nor have to deal with extra complexity and yet another function
static int avcodec_get_buffer(AVCodecContext *s, AVFrame *pic, int reget, int reference){
int ret;
pic->reference= reference;
if(reget){
ret= s->reget_buffer(s, pic);
}else
ret= s->get_buffer(s, pic);
if(ret<0)
return ret;
if (s->pkt) {
pic->pkt_pts = s->pkt->pts;
pic->pkt_pos = s->pkt->pos;
} else {
pic->pkt_pts = AV_NOPTS_VALUE;
pic->pkt_pos = -1;
}
pic->reordered_opaque= s->reordered_opaque;
pic->sample_aspect_ratio = s->sample_aspect_ratio;
pic->width = s->width;
pic->height = s->height;
pic->format = s->pix_fmt;
return ret;
}
