commit 16e0ddc40d7d8c59967ff712861d97d5e7978cf8 Author: Lynne <[email protected]> AuthorDate: Thu Oct 8 13:27:18 2026 +0900 Commit: Lynne <[email protected]> CommitDate: Thu Oct 8 14:21:36 2026 +0900 lavu/frame: allow left cropping of formats with multi-byte pixels av_frame_apply_cropping() returned AVERROR_BUG when the plane offset was more aligned than crop_left, which is always the case for single-plane formats with more than a byte per pixel (gray16, rgb48, 16-bit Bayer, p010). The rounding that follows already handles it. --- libavutil/frame.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/libavutil/frame.c b/libavutil/frame.c index be30eb09d2..ca8e8486a3 100644 --- a/libavutil/frame.c +++ b/libavutil/frame.c @@ -803,11 +803,8 @@ int av_frame_apply_cropping(AVFrame *frame, int flags) min_log2_align = FFMIN(log2_align, min_log2_align); } - /* we assume, and it should always be true, that the data alignment is - * related to the cropping alignment by a constant power-of-2 factor */ - if (log2_crop_align < min_log2_align) - return AVERROR_BUG; - + /* The data alignment is the cropping alignment scaled by a power of 2, + * up for multi-byte pixels and down for subsampled planes */ if (min_log2_align < 5 && log2_crop_align != INT_MAX) { frame->crop_left &= ~((1 << (5 + log2_crop_align - min_log2_align)) - 1); ret = calc_cropping_offsets(offsets, frame, desc); -- To stop receiving notification emails like this one, please contact [email protected]. _______________________________________________ ffmpeg-cvslog mailing list -- [email protected] To unsubscribe send an email to [email protected]
