### Usage
|
||
|
|
|
||
|
|
##### Q: Why is front camera flipped horizontally when using takePicture() or takeVideo() ?
|
||
|
|
|
||
|
|
A: It's actually not flipped - if you show your left hand, the person in the picture will show its left hand as well,
|
||
|
|
so this is the accurate representation of reality.
|
||
|
|
|
||
|
|
However, if you want to flip the result horizontally to match the preview,
|
||
|
|
you can do so by using the [snapshot APIs](../docs/capturing-media), which will respect what is shown in the preview.
|
||
|
|
|
||
|
|
##### Q: Can I use filters / overlays / cropping with takePicture() instead of takePictureSnapshot() ?
|
||
|
|
|
||
|
|
A: No, these features are only available with the snapshot API.

||

##### Q: Can I use filters / overlays / cropping with takeVideo() instead of takeVideoSnapshot() ?
|
||
|
|
|
||
|
|
A: No, these features are only available with the snapshot API.
|
||
|
|
|
||
|
|
##### Q: How can I improve takePictureSnapshot() quality?
|
||
|
|
|
||
|
|
A: The picture quality can be controlled in two ways:
|
||
|
|
- By [changing the snapshot size](../docs/snapshot-size)
|
||
|
|
- By [enabling metering](../docs/metering#picture-metering).
|
||
|
|
|
||
|
|
##### Q: How can I improve takeVideoSnapshot() quality?
|
||
|
|
|
||
|
|
A: The video quality can be controlled as follows:
|
||
|
|
- By changing the [snapshot size](../docs/snapshot-size)
|
||
|
|
- By changing the [snapshot framerate](../docs/controls#cameraPreviewFrameRate) (carefully: high values can cause dark preview)
|
||
|
|
- By changing the [video bitrate](../docs/controls#cameraVideoBitRate)
|
||
|
|
- By changing the [audio bitrate](../docs/controls#cameraAudioBitRate)
|
||
|
|
|
||
|
|
##### Q: How can I reduce the picture size?
|
||
|
|
|
||
|
|
A: The only control here is the picture size.
|
||
|
|
- When using `takePicture()`, change the [capture size](../docs/capture-size)
|
||
|
|
- When using `takePictureSnapshot()`, change the [snapshot size](../docs/snapshot-size)
|
||
|
|
|
||
|
|
##### Q: How can I reduce the video size?
|
||
|
|
|
||
|
|
A: By using video controls, for instance:
|
||
|
|
- Change the [video bitrate](../docs/controls#cameraVideoBitRate)
|
||
|
|
- Change the [audio bitrate](../docs/controls#cameraAudioBitRate)
|
||
|
|
- When using `takeVideo()`, change the [capture size](../docs/capture-size)
|
||
|
|
- When using `takeVideoSnapshot()`, change the [snapshot size](../docs/snapshot-size)
|
||
|
|
|
||
|
|
##### Q: Why is my preview / snapshot dark?
|
||
|
|
|
||
|
|
A: This is often caused by bad [framerate](../docs/controls#cameraPreviewFrameRate). Try using
|
||
|
|
a lower value, so that there's more time for frame exposure.

### Project Management
|
||
|
|
|
||
|
|
##### Q: I have found a bug with Camera1, can you fix it?
|
||
|
|
|
||
|
|
A: No, we will not address Camera1 bugs anymore - development is focused on Camera2. However, if you find a solution,
|
||
|
|
feel free to open a GitHub issue or pull requests to discuss.
|
||
|
|
|
||
|
|
##### Q: I have found a bug with my device XYZ, can you fix it?
|
||
|
|
|
||
|
|
A: No. Unless it's a device that we physically own, there is very little chance that a device-specific issues
|
||
|
|
can be solved by the maintainers. We encourage you to investigate on your own and get back to us
|
||
|
|
with a clear understanding of the problem and the solution.
|
||
|
|
|
||
|
|
##### Q: Why don't you review / comment on my GitHub issue?
|
||
|
|
|
||
|
|
A: Either because the issue did not respect the provided template, or because I don't have time.
|
||
|
|
If you are sure about the template, you can get private support by [sponsoring the project](../extra/donate).

##### Q: Why don't you review / comment on my GitHub pull requests?
|
||
|
|
|
||
|
|
A: Either because the pull requests did not respect the provided template, or because I don't have time.
|
||
|
|
If you are sure about the template, you can get private support by [sponsoring the project](../extra/donate).

|
|
||
|
|
##### Q: When will you do a new release?
|
||
|
|
|
||
|
|
A: We don't have a release schedule. New releases happen when there's enough changes to justify one,
|
||
|
|
and maintainers have had time to execute and publish the release. You can speed things up by
|
||
|
|
[sponsoring the project](../extra/donate) or pull snapshots from [jitpack.io](https://jitpack.io):
|
||
|
|
|
||
|
|
```groovy
|
||
|
|
implementation 'com.github.natario1:CameraView:master-SNAPSHOT'
|
||
|
|
implementation 'com.github.natario1:CameraView:<commit hash>'
|
||
|
|
```
|
||
|
|
|
||
|
|
Check their website for more information about how to set things up.
