Subject: [FFmpeg-devel] [PATCH 0/4] Get bits buffer end
Date: Fri, 04 Jul 2025 13:44:53 +0000
Message-ID: <pull.106.ffstaging.FFmpeg.1751636697.ffmpegagent@gmail.com> (raw)

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
