   avcodec/vulkan: fix DPX unpack offset
   The DPX Vulkan unpack shader computes a word offset as
   
       uint off = (line_off + pix_off >> 5);
   
   Due to GLSL operator precedence this is evaluated as
   line_off + (pix_off >> 5) rather than (line_off + pix_off) >> 5.
   Since line_off is in bits while off is a 32-bit word index,
   scanlines beyond y=0 use an inflated offset and the shader reads
   past the end of the DPX slice buffer.
   
   Parenthesize the expression so that the sum is shifted as intended:
   
       uint off = (line_off + pix_off) >> 5;
   
   This corrects the unpacked data and removes the CRC mismatch
   observed between the software and Vulkan DPX decoders for
   mispacked 12-bit DPX samples. The GPU OOB read itself is only
   observable indirectly via this corruption since it occurs inside
   the shader.
   
   Repro on x86_64 with Vulkan/llvmpipe (531ce713a0e8):
   
       ./configure --cc=clang --disable-optimizations --disable-stripping \
           --enable-debug=3 --disable-doc --disable-ffplay \
           --enable-vulkan --enable-libshaderc \
           --enable-hwaccel=dpx_vulkan \
           --extra-cflags='-fsanitize=address -fno-omit-frame-pointer' \
           --extra-ldflags='-fsanitize=address' && make
   
       VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/lvp_icd.json
   
   PoC: packed 12-bit DPX with the packing flag cleared so the unpack
   shader runs (4x64 gbrp12le), e.g. poc12_packed0.dpx.
   
   Software decode:
   
       ./ffmpeg -v error -i poc12_packed0.dpx -f framecrc -
       -> 0, ..., 1536, 0x26cf81c2
   
   Vulkan hwaccel decode:
   
       VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/lvp_icd.json \
       ./ffmpeg -v error -init_hw_device vulkan \
           -hwaccel vulkan -hwaccel_output_format vulkan \
           -i poc12_packed0.dpx \
           -vf hwdownload,format=gbrp12le -f framecrc -
       -> 0, ..., 1536, 0x71e10a51
   
   The only difference between the two runs is the Vulkan unpack
   shader, and the stable CRC mismatch indicates that it is reading
   past the intended DPX slice region.

   avformat/amr: add P bits check to avoid mis-detects
   Fix #21056
   
   Refer to RFC 3267 Section 4.4.2:
   
   A ToC entry takes the following format in octet-aligned mode:
   
    0 1 2 3 4 5 6 7
   +-+-+-+-+-+-+-+-+
   |F|  FT   |Q|P|P|
   +-+-+-+-+-+-+-+-+
   
   P bits: padding bits, MUST be set to zero.
