| * pixfmt: remove misleading and broken documentationwm42015-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was probably broken some time ago. The breakage is now part of the ABI. For example, we have: AV_PIX_FMT_XYZ12BE AV_PIX_FMT_NV16 AV_PIX_FMT_NV20LE AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian format it should be even. This must have been quite obvious when these formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but nobody cared or knew about this. The future libavutil major bump will also break this additionally, because disabling FF_API_VDPAU will remove an odd number of entries from the middle of the enum.

| * x86inc: Clear __SECT__Timothy Gu2015-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Silences warning(s) like: libavcodec/x86/fft.asm:93: warning: section flags ignored on section redeclaration The cause of this warning is that because `struc` and `endstruc` attempts to revert to the previous section state [1]. The section state is stored in the macro __SECT__, defined by x86inc.asm to be `.note.GNU-stack ...`, through the `SECTION` directive [2]. Thus, the `.note.GNU-stack` section is defined twice (once in x86inc.asm, once during `endstruc`), causing the warning. That is the first part of the commit: using the primitive `[section]` format for .note.GNU-stack etc., which does not update `__SECT__` [2]. That fixes only half of the problem. Even without any `SECTION` directives, `__SECT__` is predefined as `.text`, which conflicting with the later `SECTION_TEXT` (which expands to `.text align=16`).

* | avcodec/mips: Split uni mc optimizations to new fileShivraj Patil2015-05-28
| | | | | | | | | | | | | | | | | | This patch moves HEVC code of uni mc cases to new file hevc_mc_uni_msa.c. (There are total 5 sub-modules of HEVC mc functions, if we add all these modules in one single file, its size would be huge (~750k) & difficult to maintain, so splitting it in multiple files) This patch also adds new HEVC header file libavcodec/mips/hevc_macros_msa.h Signed-off-by: Shivraj Patil <shivraj.patil@imgtec.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | avutil/mips: Restructure of generic macrosShivraj Patil2015-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes restructuring of existing macros and addition of more generic macros. This change was necessary to avoid repeated review comments in remaining patches which we were about to submit. Also this patch reduces number of code lines due to maximum use of generic macros, allows better code alignment & readability etc. These modifications in commonly used .libavutil/mips/generic_macros_msa.h. impacts the already accepted code, hence re-submitting it in 2/4,3/4 & 4/4. Overall, this patch set is just upgrading the code with styling changes and will bring it in sync with MIPS-SIMD optimized latest codebase at our end.
