Before filing a bug:
-----------------------
- Search existing issues, including issues that are closed:
https://github.com/google/ExoPlayer/issues?q=is%3Aissue
- Consult our developer website, which can be found at https://exoplayer.dev/.
It provides detailed information about supported formats and devices.
- Learn how to create useful log output by using the EventLogger:
https://exoplayer.dev/listening-to-player-events.html#using-eventlogger
- Rule out issues in your own code. A good way to do this is to try and
reproduce the issue in the ExoPlayer demo app. Information about the ExoPlayer
demo app can be found here:
http://exoplayer.dev/demo-application.html.
When reporting a bug:
-----------------------
Fill out the sections below, leaving the headers but replacing the content. If
you're unable to provide certain information, please explain why in the relevant
section. We may close issues if they do not include sufficient information.
### [REQUIRED] Issue description
Describe the issue in detail, including observed and expected behavior.
### [REQUIRED] Reproduction steps
Describe how the issue can be reproduced, ideally using the ExoPlayer demo app
or a small sample app that you’re able to share as source code on GitHub.
### [REQUIRED] Link to test content
Provide a JSON snippet for the demo app’s media.exolist.json file, or a link to
media that reproduces the issue. If you don't wish to post it publicly, please
submit the issue, then email the link to dev.exoplayer@gmail.com using a subject
in the format "Issue #1234", where "#1234" should be replaced with your issue
number. Provide all the metadata we'd need to play the content like drm license
urls or similar. If the content is accessible only in certain countries or
regions, please say so.
### [REQUIRED] A full bug report captured from the device
Capture a full bug report using "adb bugreport". Output from "adb logcat" or a
log snippet is NOT sufficient. Please attach the captured bug report as a file.
If you don't wish to post it publicly, please submit the issue, then email the
bug report to dev.exoplayer@gmail.com using a subject in the format
"Issue #1234", where "#1234" should be replaced with your issue number.
### [REQUIRED] Version of ExoPlayer being used
Specify the absolute version number. Avoid using terms such as "latest".
### [REQUIRED] Device(s) and version(s) of Android being used
Specify the devices and versions of Android on which the issue can be
reproduced, and how easily it reproduces. If possible, please test on multiple
devices and Android versions.

### From JCenter ###
#### 1. Add repositories ####
The easiest way to get started using ExoPlayer is to add it as a gradle
dependency. You need to make sure you have the JCenter and Google repositories
dependency. You need to make sure you have the Google and JCenter repositories
included in the `build.gradle` file in the root of your project:
```gradle
repositories {
jcenter()
google()
jcenter()
}

# ExoPlayer GL demo
This app demonstrates how to render video to a [GLSurfaceView][] while applying
a GL shader.
The shader shows an overlap bitmap on top of the video. The overlay bitmap is
drawn using an Android canvas, and includes the current frame's presentation
timestamp, to show how to get the timestamp of the frame currently in the
off-screen surface texture.
[GLSurfaceView]: https://developer.android.com/reference/android/opengl/GLSurfaceView

# ExoPlayer SurfaceControl demo
This app demonstrates how to use the [SurfaceControl][] API to redirect video
output from ExoPlayer between different views or off-screen. `SurfaceControl`
is new in Android 10, so the app requires `minSdkVersion` 29.
The app layout has a grid of `SurfaceViews`. Initially video is output to one
of the views. Tap a `SurfaceView` to move video output to it. You can also tap
the buttons at the top of the activity to move video output off-screen, to a
full-screen `SurfaceView` or to a new activity.
When using `SurfaceControl`, the `MediaCodec` always has the same surface
attached to it, which can be freely 'reparented' to any `SurfaceView` (or
off-screen) without any interruptions to playback. This works better than
calling `MediaCodec.setOutputSurface` to change the output surface of the codec
because `MediaCodec` does not re-render its last frame when that method is
called, and because you can move output off-screen easily (`setOutputSurface`
can't take a `null` surface, so the player has to use a `DummySurface`, which
doesn't handle protected output on all devices).

# ExoPlayer AV1 extension #
The AV1 extension provides `Libgav1VideoRenderer`, which uses libgav1 native
library to decode AV1 videos.
## License note ##
Please note that whilst the code in this repository is licensed under
[Apache 2.0][], using this extension also requires building and including one or
more external libraries as described below. These are licensed separately.
[Apache 2.0]: https://github.com/google/ExoPlayer/blob/release-v2/LICENSE
## Build instructions (Linux, macOS) ##
To use this extension you need to clone the ExoPlayer repository and depend on
its modules locally. Instructions for doing this can be found in ExoPlayer's
[top level README][].
In addition, it's necessary to fetch cpu_features library and libgav1 with its
dependencies as follows:
* Set the following environment variables:
```
cd "<path to exoplayer checkout>"
EXOPLAYER_ROOT="$(pwd)"
AV1_EXT_PATH="${EXOPLAYER_ROOT}/extensions/av1/src/main"
```
* Fetch cpu_features library:
```
cd "${AV1_EXT_PATH}/jni" && \
git clone https://github.com/google/cpu_features
```
* Fetch libgav1:
```
cd "${AV1_EXT_PATH}/jni" && \
git clone https://chromium.googlesource.com/codecs/libgav1 libgav1
```
* Fetch Abseil:
```
cd "${AV1_EXT_PATH}/jni/libgav1" && \
git clone https://github.com/abseil/abseil-cpp.git third_party/abseil-cpp
```
* [Install CMake][].
Having followed these steps, gradle will build the extension automatically when
run on the command line or via Android Studio, using [CMake][] and [Ninja][]
to configure and build libgav1 and the extension's [JNI wrapper library][].
[top level README]: https://github.com/google/ExoPlayer/blob/release-v2/README.md
[Install CMake]: https://developer.android.com/studio/projects/install-ndk
[CMake]: https://cmake.org/
[Ninja]: https://ninja-build.org
[JNI wrapper library]: https://github.com/google/ExoPlayer/blob/release-v2/extensions/av1/src/main/jni/gav1_jni.cc
## Build instructions (Windows) ##
We do not provide support for building this extension on Windows, however it
should be possible to follow the Linux instructions in [Windows PowerShell][].
[Windows PowerShell]: https://docs.microsoft.com/en-us/powershell/scripting/getting-started/getting-started-with-windows-powershell
## Using the extension ##
Once you've followed the instructions above to check out, build and depend on
the extension, the next step is to tell ExoPlayer to use `Libgav1VideoRenderer`.
How you do this depends on which player API you're using:
* If you're passing a `DefaultRenderersFactory` to `SimpleExoPlayer.Builder`,
you can enable using the extension by setting the `extensionRendererMode`
parameter of the `DefaultRenderersFactory` constructor to
`EXTENSION_RENDERER_MODE_ON`. This will use `Libgav1VideoRenderer` for
playback if `MediaCodecVideoRenderer` doesn't support decoding the input AV1
stream. Pass `EXTENSION_RENDERER_MODE_PREFER` to give `Libgav1VideoRenderer`
priority over `MediaCodecVideoRenderer`.
* If you've subclassed `DefaultRenderersFactory`, add a `Libvgav1VideoRenderer`
to the output list in `buildVideoRenderers`. ExoPlayer will use the first
`Renderer` in the list that supports the input media format.
* If you've implemented your own `RenderersFactory`, return a
`Libgav1VideoRenderer` instance from `createRenderers`. ExoPlayer will use the
first `Renderer` in the returned array that supports the input media format.
* If you're using `ExoPlayer.Builder`, pass a `Libgav1VideoRenderer` in the
array of `Renderer`s. ExoPlayer will use the first `Renderer` in the list that
supports the input media format.
Note: These instructions assume you're using `DefaultTrackSelector`. If you have
a custom track selector the choice of `Renderer` is up to your implementation.
You need to make sure you are passing a `Libgav1VideoRenderer` to the player and
then you need to implement your own logic to use the renderer for a given track.
## Using the extension in the demo application ##
To try out playback using the extension in the [demo application][], see
[enabling extension decoders][].
[demo application]: https://exoplayer.dev/demo-application.html
[enabling extension decoders]: https://exoplayer.dev/demo-application.html#enabling-extension-decoders
## Rendering options ##
There are two possibilities for rendering the output `Libgav1VideoRenderer`
gets from the libgav1 decoder:
* GL rendering using GL shader for color space conversion
* If you are using `SimpleExoPlayer` with `PlayerView`, enable this option by
setting `surface_type` of `PlayerView` to be
`video_decoder_gl_surface_view`.
* Otherwise, enable this option by sending `Libgav1VideoRenderer` a message
of type `C.MSG_SET_VIDEO_DECODER_OUTPUT_BUFFER_RENDERER` with an instance of
`VideoDecoderOutputBufferRenderer` as its object.
* Native rendering using `ANativeWindow`
* If you are using `SimpleExoPlayer` with `PlayerView`, this option is enabled
by default.
* Otherwise, enable this option by sending `Libgav1VideoRenderer` a message of
type `C.MSG_SET_SURFACE` with an instance of `SurfaceView` as its object.
Note: Although the default option uses `ANativeWindow`, based on our testing the
GL rendering mode has better performance, so should be preferred
