Carl Eugen Hoyos	6dbb64fdcc	lavc/v4l2_m2m_enc: Add missing braces around initializers. Fixes the following warnings: libavcodec/v4l2_m2m_enc.c:51:12: warning: missing braces around initializer libavcodec/v4l2_m2m_enc.c:71:12: warning: missing braces around initializer	6 years ago
Mark Thompson	a0c624e299	avcodec: v4l2_m2m: fix races around freeing data on close 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).

wm4	55eebf2a11	v4l_m2m: add missing AV_CODEC_CAP_DELAY flags This is pretty much a requirement for any codec that handles modern codecs like h264, but it was missing. Potentially could lead to issues like missing frames at the end of a stream. Tested-by: Jorge Ramirez <jorge.ramirez-ortiz@linaro.org>	7 years ago
wm4	b945fed629	avcodec: add metadata to identify wrappers and hardware decoders Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit `47687a2f8a`.	7 years ago

Mark Thompson	a0d076f3ef	lavc/v4l2: Remove use of lfind() This is not present in older bionic and therefore fails to build there, and the code is much simpler without it anyway.	7 years ago
Jorge Ramirez-Ortiz	1ef7752d64	libavcodec: v4l2: add support for v4l2 mem2mem codecs 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>	7 years ago
