Ronald S. Bultje	4147b337c1	vp9: fix memory corruption if header decoding fails after size change.	11 years ago
Ronald S. Bultje	c9e6325ed9	vp9/x86: use explicit register for relative stack references. Before this patch, we explicitly modify rsp, which isn't necessarily universally acceptable, since the space under the stack pointer might be modified in things like signal handlers. Therefore, use an explicit register to hold the stack pointer relative to the bottom of the stack (i.e. rsp). This will also clear out valgrind errors about the use of uninitialized data that started occurring after the idct16x16/ssse3 optimizations were first merged.	11 years ago

James Darnley	fa20babb46	lavf/avienc: use metadata_header_padding The muxer will write at least the number of bytes requested and possibly up to 3 bytes more. This is because the muxer writes 32-bit integers and the format requires 4-byte alignment anyway. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

James Darnley	72eeb18468	lavf/flacenc: use metadata_header_padding Allows a user to control the amount, if any, of padding they want added to the file. If set to zero the block will not be written at all. If set to some positive number four more bytes will be added to the file due to the small header required for the block.

James Darnley	86bee7984e	AVFormatContext: add metadata_header_padding field This field is used to store the number of bytes that should be written as padding to a metadata header of a file. For example: - The FLAC format's METADATA_BLOCK_PADDING [1] - The ID3v2 tag format's padding [2] [1] http://xiph.org/flac/format.html#metadata_block_padding [2] http://id3.org/id3v2.3.0#ID3v2_overview Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
