Suppose a sequence in h264 is IBB*P*BBPB*B[*P]BBP How can I extract the previous (in the display order) AV_PICTURE_TYPE_P frame of the current slice from the DPB list? how about extracting both next and previous (in the display order) of a AV_PICTURE_TYPE_B slice?
for example, for the input of the third AV_PICTURE_TYPE_P slice of a sequence ( in the bracket in the above example), I want to extract the second AV_PICTURE_TYPE_P picture of the sequence form. Is that possible? the place that I want to do it is after the line > if ((err = ff_h264_decode_slice_header(h, sl))) in the function > static int decode_nal_units(H264Context *h, const uint8_t *buf, int > buf_size, > int parse_extradata) in the file h264.c thank you. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
