[libav-devel] [PATCH] cbs_h264: Fix overflow in shifts

From: Mark Thompson The type of the result of a shift operation is unaffected by the type of the right operand, so some existing code overflows with undefined behaviour when the element length is 32. Add a helper macro to calculate the maximum value correctly and then use it everywhere this

[libav-devel] [PATCH 05/14] cbs_h265: Use helper macro for maximum values of fixed-width elements

From: Mark Thompson Apply the same logic as the previous patch to H.265. There are no cases which currently overflow here, but this is still more consistent. --- libavcodec/cbs_h265_syntax_template.c | 16 1 file changed, 8 insertions(+), 8 deletions(-) diff --git
