* avcodec/hevc_ps: add a function to uninitialize parameter set buffersJames Almer2018-01-21

* lavf/rawdec: Also probe the last byte of mjpeg streams.Carl Eugen Hoyos2018-01-21
| | | | Fixes ticket #6957.
* avcodec: v4l2_m2m: context: fix raising warning on POLLERRJorge Ramirez-Ortiz2018-01-21
| | | | | | | | | | | | | | During the initialization stage, the codec attempts to get free buffers from the driver before any have been queued (this is to keep the code simple and generic) When the kernel driver detects this situation, it returns POLLERR in revents and ffmpeg therefore raises a warning. This commit disables the warning since no buffers were queued to the driver yet. Signed-off-by: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@linaro.org>
* avcodec: v4l2_m2m: remove unnecessary timeout.Jorge Ramirez-Ortiz2018-01-21
| | | | | | | | | | | | | | Qualcomm's db410c/db820 Venus driver currently present in mainline kernel has a bug which mishandles the CMD_STOP requests causing the decoder to block while draining [1]. This patch removes the workaround that was used to prevent that situation. Encoding/Decoding tested on db820c. [1] on CMD_STOP, the driver is flushing all buffers and never raising IPIPE which ends up in blocking on poll.
* avcodec: v4l2_m2m: fix races around freeing data on closeMark Thompson2018-01-21
| | | | | | | | Refcount all of the context information. This also fixes a potential segmentation fault when accessing freed memory (buffer returned after the codec has been closed). Tested-by: Jorge Ramirez-Ortiz <jorge.ramirez.ortiz@gmail.com>

* x86inc: Enable AVX emulation for floating-point pseudo-instructionsHenrik Gramner2018-01-20
| | | | | | | There are 32 pseudo-instructions for each floating-point comparison instruction, but only 8 of them are actually valid in legacy-encoded mode. The remaining 24 requires the use of VEX-encoded (v-prefixed) instructions and can therefore be disregarded for this purpose.
* avdevice/decklink: Fix compilation of module on OSXDevin Heitmueller2018-01-20
| | | | | | | | | | | | | Clang applies the missing-prototypes warning on C++ files, whereas gcc only applies it to C. As a result, the decklink_common.cpp file fails to build because of missing prototypes in DecklinkDispatch.cpp (which is #included by decklink_common.cpp). We don't want to change the actual Blackmagic SDK sources, so suppress the warning just for that one #include.

* | hwcontext_d3d11va: implement av_hwdevice_get_hwframe_constraints()wm42018-01-16
| | | | | | | | | | | | | | D3D11 has rather fine grained per format capabilities for different uses that can be queried at runtime. Since we don't know what the user wants to do with the formats when av_hwdevice_get_hwframe_constraints() is called, we simply return all formats that have the most basic support.
* | avformat: make avformat_network_init() explicitly optionalwm42018-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was sort of optional before - if you didn't call it, networking was initialized on demand, and an ugly warning was logged. Also, the doxygen comments threatened that it would be made strictly required one day. Make it explicitly optional. I would prefer to deprecate it fully, but there might still be legitimate reasons to use this. But the average user won't need it. This is needed only for two reasons: to initialize TLS libraries like OpenSSL and GnuTLS, and winsock. OpenSSL and GnuTLS were already silently initialized on demand if the global network init function was not called. They also have various thread-safety acrobatics, which make concurrent initialization within libavformat safe. In addition, the libraries are moving towards making their global init functions safe, which removes all need for central global init. In particular, GnuTLS 3.5.16 and OpenSSL 1.1.0g have been found to have safe init functions. In all cases, they use internal reference counters to avoid that the global uninit functions interfere with concurrent uses of the library by other API users who called global init. winsock should be thread-safe as well, and maintains an internal reference counter as well. Since we still support ancient TLS libraries, which do not have this fixed, and since it's unknown whether winsock and GnuTLS reinitialization is costly in any way, don't deprecate the libavformat functions yet.

* | hwcontext_vdpau: implement av_hwdevice_get_hwframe_constraints()wm42018-01-15
| | | | | | | | | | | | | | | | | | | | | | In addition, this does not allow creating frames contexts with sw_format for which no known transfer formats exist. In theory, we should check whether the chroma format (i.e. the sw_format) is supported at all by the vdpau driver, but checking for transfer formats has the same effect. Note that the pre-existing code adds 1 to priv->nb_pix_fmts[i] for unknown reason, and some checks need to account for that to check for empty lists. They are not off-by-one errors.
