* ppc: configure: Support ISA 2.06 and laterLuca Barbato2015-05-31
| | | | | | | POWER 7 and POWER 8 support VSX and ldbrx. POWER 8 supports additional extended VSX instructions introduced with ISA 2.07.

* network: prevent SIGPIPE on OSXwm42015-05-31
| | | | | | | | OSX does not know MSG_NOSIGNAL. BSD (which OSX is based on) has got the socket option SO_NOSIGPIPE (even if modern BSDs also support MSG_NOSIGNAL). Signed-off-by: Martin Storsjö <martin@martin.st>

* 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.

* mpegvideo: Drop exchange_uv() function and use its code directlyVittorio Giovara2015-05-28
| | | | Code is small enough that there is no advantage in a separate function.
* tls_gnutls: Add missing includes for the gcrypt thread safety callbacksMartin Storsjö2015-05-28

* 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`).

* mpegvideo: Have ff_mpeg_unref_picture use AVCodecContext directlyVittorio Giovara2015-05-22
| | | | | This skips setting the memory to 0 but allows for reuse on different contextes. Oracle did not report any unsual activity because of it.
* mpegvideo: Drop stream_codec_tagVittorio Giovara2015-05-22
| | | | The field is unused.
* mpegvideo: Drop err_recognitionVittorio Giovara2015-05-22
| | | | It is just a duplicate of an AVCodecContext member so use it instead.
* mpegvideo: Drop flags and flags2Vittorio Giovara2015-05-22

* tls: Remove the nonblocking codeMartin Storsjö2015-05-22
| | | | | | | | Since the underlying URLContext read functions are used, they handle interruption, without having to handle it at this level. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Use custom IO to read from the URLContextMartin Storsjö2015-05-22
| | | | | | | | | | | | | | This avoids hijacking the fd, by reading using the normal URLContext functions instead. This allowing reading data that has been buffered in the underlying URLContext. This avoids using the libraries own send functions that can cause SIGPIPE. The fd is still used for polling the lowlevel socket, for waiting for retries.

* hevc: make avcodec_decode_video2() fail if get_format() failswm42015-05-19
| | | | | | | | | | | | Personally, I need the decoder to back out if get_format() returns no usable pixel format. This didn't work because the error code was not propagated down the call chain. This in turn happened because the variable declaration removed in this patch shadowed the variable, whose value is returned at the end of the function. Consequently, failures of decode_nal_unit() were ignored in this place. Reviewed-by: Andreas Cadhalpun <andreas.cadhalpun@googlemail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* vmnc: Delay pixel size checkVittorio Giovara2015-05-19
| | | | | | | | Some clients incorrectly set 24 as bits_per_coded_sample, while the actual value is preserved in one of the codec headers. In order to work around this, delay the check until decode_frame(). Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | This is useful for client programs to ask for nv12 surfaces instead of the current default (uyvy), since those are more efficient to decode to. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* libx265: Use the Multi-library InterfaceGopu Govindaswamy2015-05-13
| | | | | | | | | | | | | | | Use the Multi-library interface to load at runtime x265 libraries supporting alternative bit depths (e.g. 8bit and 16bit). The linked library will try to load the library supporting the pixel format if it is not supported by itself. Fallback requesting the native library (passing 0 to x265_api_get) if a library supporting the requested bit depth is not available.
