[FFmpeg-devel] [PATCH] avformat/smoothstreamingenc: Move buffers to the end of structs

[Andreas Rheinhardt]

Andreas Rheinhardt:
> This reduces codesize because the offsets of commonly used elements
> are now smaller and thus need less bytes to encode in ptr+offset
> addressing modes (with GCC 11.2 on x64: 0x1b8b -> 0x1a7b).

Will apply this patchset tonight unless there are objections.
