Changes in v3: - fix a bug in #10: did not check buffer size before reading it - removed the check for frame dimensions set-in-stone in #11, which broke e.g. codec20. - added codec20 "decoder" (#13) Changes in v2: - reordered first 3 patches as some regressed things without the following patch applied. - fixed codec4 left/top being swapped, resulting in weird visuals in L5PLAY.ANM - additional handling for unaligned objects in file (see #4) - reimplement ANIMv1 store/fetch handling (see #11) - added codec45 to ignore (see #12 for an explanation) - add myself as sanm.c/smush.c Maintainer, as requested by Michael (#13) There are still a few palette issues in RA1: when the first FRME does not contain any video data, the palette seems to be all-black until the first NPAL (=new palette) chunk is encountered, although every ANM and SAN file have a full palette in their header. Manuel Lauss (14): avcodec/sanm: disable left/top for fullscreen codecs avcodec/sanm: FOBJ left/top are signed values avcodec/sanm: better frame size detection for old codecs avcodec/sanm: better ANIMv1 engine support avcodec/sanm: fix codec3 avcodec/sanm: codec2 decoder avcodec/sanm: codec23 decoder avcodec/sanm: codec21 decoder avcodec/sanm: codec4/5/33/34 decoder avcodec/sanm: codec37: reimplement comp4 avcodec/sanm: implement STOR/FTCH for ANIMv1 avcodec/sanm: ignore codec45 avcodec/sanm: codec20 decoder MAINTAINERS: add Manuel Lauss as sanm.c/smush.c Maintainer MAINTAINERS | 2 + libavcodec/sanm.c | 710 ++++++++++++++++++++++++++++++++++++++++------ 2 files changed, 621 insertions(+), 91 deletions(-) -- 2.49.0 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
