f6d48b618a avcodec/mediacodec: add av_mediacodec_render_buffer_at_time() 
The existing av_mediacodec_release_buffer allows the user to render
or discard the Surface-backed frame. This new method allows the user
to control exactly when the frame will be rendered to its SurfaceView.

Available since Android API 21.

'OMX.SEC.avc.dec' is a valid hardware decoder, while the decoders
we seek to blacklist all match 'OMX.SEC.*.sw.dec'.

b8c158a4ed lavc/mediacodec_wrapper: do not discard codecs reporting they do not support any profile 
Depending on the device, some (VP8/VP9/...) decoders report that they do
not support any profiles.

376d8fb2c5 lavc/ffjni: replace ff_jni_{attach,detach} with ff_jni_get_env 
If a JNI environment is not already attached to the thread where the
MediaCodec calls are made the current implementation will attach /
detach an environment for each MediaCodec call wasting some CPU time.

ff_jni_get_env replaces ff_jni_{attach,detach} by permanently attaching
an environment (if it is not already the case) to the current thread.
The environment will be automatically detached at the thread destruction
using a pthread_key callback.

Saves around 5% of CPU time (out of 20%) while decoding a stream with
MediaCodec.

e452abc5c2 lavc/mediacodec: refactor ff_AMediaCodecList_getCodecByType 
Allows to select a codec (encoder or decoder) only if it supports a
specific profile.

Adds ff_AMediaCodecProfile_getProfileFromAVCodecContext to convert an
AVCodecContext profile to a MediaCodec profile. It only supports H264
for now.

The codepath using MediaCodecList.findDecoderForFormat() (Android >= 5.0)
has been dropped as this method does not allow to select a decoder
compatible with a specific profile.

93f4d1646e lavc/mediacodec: bypass width/height restrictions when looking for a decoder 
Codec width/height restrictions seem hardcoded at the OMX level and
seem arbitrary. Bypassing those restrictions allows a device to decode
streams at higher resolutions.

For example it allows a Nexus 5 to decode h264 streams with a resolution
higher than 1920x1080.
