[FFmpeg-devel] [PATCH 0/4] Get bits buffer end

[Andreas Rheinhardt]

ffmpegagent:
> This patchset eliminates GetBitContext.buffer_end (which is mostly unused).
> It therefore automatically fixes the UB that happens upon init_get_bits()
> failure (when using pre-C23).
> 
> Andreas Rheinhardt (4):
>   avcodec/bytestream: Add const where appropriate
>   avcodec/vvc/dec: Don't use GetBit-API when byte-aligned
>   avcodec/get_bits: Add get_bits_bytesize()
>   avcodec/get_bits: Remove GetBitContext.buffer_end
