* release/0.8: Update RELEASE file for 0.7.6 Update changelog for 0.7.6 release ea: check chunk_size for validity. png: check bit depth for PAL8/Y400A pixel formats. x86: fix build with gcc 4.7 qdm2: clip array indices returned by qdm2_get_vlc(). kmvc: Check palsize. aacsbr: prevent out of bounds memcpy(). rtpdec_asf: Fix integer underflow that could allow remote code execution dpcm: ignore extra unpaired bytes in stereo streams. tqi: Pass errors from the MB decoder h264: Add check for invalid chroma_format_idc adpcm: ADPCM Electronic Arts has always two channels h263dec: Disallow width/height changing with frame threads. vqavideo: return error if image size is not a multiple of block size celp filters: Do not read earlier than the start of the 'out' vector. motionpixels: Clip YUV values after applying a gradient. h263: more strictly forbid frame size changes with frame-mt. h264: additional protection against unsupported size/bitdepth changes. Update for 0.8.11 Conflicts: Doxyfile RELEASE VERSION Merged-by: Michael Niedermayer <[email protected]>
