xvmc.h used FF_API_* macros before, but they were removed in
1c63aed232febf4404659bf006237ee4f7f17c9c, leaving the include
unused.
The ones in android_camera.c and mediacodec_wrapper.c have been
added due to a misunderstanding, fixed in
c0bce367e4932f0fb09195e6978ac1a5a60480a4 and
13b77af2f0b56d6c87bb147947337981c21f4245.
The one in mediacodec.c seems to never have been used at all.

Added in Android 10 it provides a reliable way of filtering out
software decoders, unlike existing string-based checks.

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'.

Additionally blacklist ffmpeg, Samsung and Qualcomm
software implementations offered through MediaCodec.

any profile
Depending on the device, some (VP8/VP9/...) decoders report that they do
not support any profiles.

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.

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.

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.
