[FFmpeg-devel] [PATCH] avfilter/vf_overlay: fix alpha blending for planar formats with a transparent background

When the background had an alpha channel, the old code in blend_plane calculated premultiplied alpha from the destination plane colors instead of the destination alpha. Also the calculation of the output alpha should only happen after the color planes are already finished. Fixes output of:

Re: [FFmpeg-devel] [PATCH] JPEG2000 encoding with variable codeblock size

The standard ISO/IEC FCD15444-1 specify limits for the exponent values and their sum. That is codeblock size xcb and ycb are defined as: xcb = 2^(xvalue+2) and ycb = 2^(yvalue+2) with values that ranges from a minimum of 2 and a maximum of 10. Moreover the sum should be less or equal to 12

Before I attempt to come up with and attempt to submit a patch only to be rejected and subsequently ignored, is there any interest in adding support for EVS? Specifically, EVS files and EVS coded audio in 3GP containers. This would not include the EVS codec as that costs $$. Thanks, Bob
