avcodec/ffv1enc: remap table size is 1<<bits_per_raw_sample not fixed 65536 not a bugfix as this path was only used for float16 but it makes sense to allow using this for integers too Signed-off-by: Michael Niedermayer <mich...@niedermayer.cc> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=3813559660557415820140d6f7687ad1db5d5708 --- libavcodec/ffv1enc.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/libavcodec/ffv1enc.c b/libavcodec/ffv1enc.c index 7e1dfd4b6f..80cf27bc11 100644 --- a/libavcodec/ffv1enc.c +++ b/libavcodec/ffv1enc.c @@ -1168,6 +1168,7 @@ static void choose_rct_params(const FFV1Context *f, FFV1SliceContext *sc, static void encode_histogram_remap(FFV1Context *f, FFV1SliceContext *sc) { + int len = 1 << f->bits_per_raw_sample; int flip = sc->remap == 2 ? 0x7FFF : 0; for (int p= 0; p < 1 + 2*f->chroma_planes + f->transparency; p++) { @@ -1179,7 +1180,7 @@ static void encode_histogram_remap(FFV1Context *f, FFV1SliceContext *sc) memset(state, 128, sizeof(state)); put_symbol(&sc->c, state[0], 0, 0); memset(state, 128, sizeof(state)); - for (int i= 0; i<65536; i++) { + for (int i= 0; i<len; i++) { int ri = i ^ ((i&0x8000) ? 0 : flip); int u = sc->fltmap[p][ri]; sc->fltmap[p][ri] = j; _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
