[FFmpeg-devel] [PATCH 3/3] vp9: recon: Use emulated edge to prevent buffer overflows

read buffer overflow. This triggers segfaults in Firefox for video resolutions which result in a page aligned picture size like 1280x640. Prevent this by using emulated edge in this case. Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1881185 Signed-off-by: Janne Grunau --- libavcodec/vp9re

[FFmpeg-devel] [PATCH 1/3] aarch64: vp9mc: Load only 12 pixels in the 4 pixel wide horizontal filter

like seen by Firefox a read beyond the end of the buffer results in a segfault. After the over-read is reduced to a single pixel it's reasonable to use VP9's emulated edge motion compensation for this. Fixes: https://bugzilla.mozilla.org/show_bug.cgi?id=1881185 Signed-off-by: Ja
