TODO Actual implementation. Signed-off-by: Nicolas George <geo...@nsup.org> --- libavutil/frame.h | 9 +++++++++ 1 file changed, 9 insertions(+)
Here is a proposal for actually fixing the alignment problems that are all over the place in the current code base. Note that it is only a design proposal, all the actual implementation is missing. I do not want to waste my time implementing if the design is to be bikeshedded to death. diff --git a/libavutil/frame.h b/libavutil/frame.h index 4d8c1bed4f..162ea0716c 100644 --- a/libavutil/frame.h +++ b/libavutil/frame.h @@ -746,6 +746,15 @@ void av_frame_remove_side_data(AVFrame *frame, enum AVFrameSideDataType type); const char *av_frame_side_data_name(enum AVFrameSideDataType type); /** + * Realign the data pointers of a frame. + * Make sure all frame data pointers have the alignment lower bits cleared, + * i.e. are a multiple of 1<<alignment. + * If not, a new frame is allocated and overwrites the current one. + * @return >=0 for success or an AVERROR code. + */ +int av_frame_realign(AVFrame *frame, unsigned align); + +/** * @} */ -- 2.11.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
