* libavcodec: v4l2: add support for v4l2 mem2mem codecsJorge Ramirez-Ortiz2017-09-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patchset enhances Alexis Ballier's original patch and validates it using Qualcomm's Venus hardware (driver recently landed upstream [1]). This has been tested on Qualcomm's DragonBoard 410c and 820c Configure/make scripts have been validated on Ubuntu 10.04 and 16.04. Tested decoders: - h264 - h263 - mpeg4 - vp8 - vp9 - hevc Tested encoders: - h264 - h263 - mpeg4 Tested transcoding (concurrent encoding/decoding) Some of the changes introduced: - v4l2: code cleanup and abstractions added - v4l2: follow the new encode/decode api. - v4l2: fix display size for NV12 output pool. - v4l2: handle EOS (EPIPE and draining) - v4l2: vp8 and mpeg4 decoding and encoding. - v4l2: hevc and vp9 support. - v4l2: generate EOF on dequeue errors. - v4l2: h264_mp4toannexb filtering. - v4l2: fixed make install and fate issues. - v4l2: codecs enabled/disabled depending on pixfmt defined - v4l2: pass timebase/framerate to the context - v4l2: runtime decoder reconfiguration. - v4l2: add more frame information - v4l2: free hardware resources on last reference being released - v4l2: encoding: disable b-frames for upstreaming (patch required) [1] https://lwn.net/Articles/697956/ System Level view: v42l_m2m_enc/dec --> v4l2_m2m --> v4l2_context --> v4l2_buffers Reviewed-by: Jorge Ramirez <jorge.ramirez-ortiz@linaro.org> Reviewed-by: Alexis Ballier <aballier@gentoo.org> Tested-by: Jorge Ramirez <jorge.ramirez-ortiz@linaro.org> Signed-off-by: wm4 <nfxjfg@googlemail.com>

* dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-27
| | | | | | | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Merges Libav commit f9e7a2f95a7194a8736cc1416a03a1a0155a3e9f. Also adds untested VP9 support. The check for DXVA2 COBJs is removed. Just update your MinGW to something newer than a 5 year old release. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* lavc: remove libschroedinger encoding and decoding wrappersRostislav Pehlivanov2017-05-29
| | | | | | | | | The library has stopped being developed and Debian has removed it from its repositories citing security issues. The native Dirac decoder supports everything the library has and basic encoding support is still provided via the native vc2 (Dirac Pro, intra only version of Dirac) encoder. Hence, there's no reason to still support linking to the library and potentially leading users into security issues.
* lavf: remove the libnut library wrapperRostislav Pehlivanov2017-05-29
| | | | | libnut is outdated and not developed anymore, all nut developments happens in this repo, so users are getting mislead

* lavc: add a librsvg rasterization library wrapperRostislav Pehlivanov2017-05-16
| | | | | | | | | | Enables rendering of SVG images. This is possible since SVG images still contain and specify the dimensions in pixels to which they've been drawn to and thus enable browsers to display them without any external data. Users can still override and generate images with arbitrary resolutions. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
