High speed ( >= 100fps) quality level corresponding to the lowest available resolution.

 For all the high speed profiles defined below ((from QUALITY_HIGH_SPEED_LOW to QUALITY_HIGH_SPEED_2160P), they are similar as normal recording profiles, with just higher output frame rate and bit rate. Therefore, setting these profiles with MediaRecorder.setProfile without specifying any other encoding parameters will produce high speed videos rather than slow motion videos that have different capture and output (playback) frame rates. To record slow motion videos, the application must set video output (playback) frame rate and bit rate appropriately via MediaRecorder.setVideoFrameRate and MediaRecorder.setVideoEncodingBitRate based on the slow motion factor. If the application intends to do the video recording with MediaCodec encoder, it must set each individual field of MediaFormat similarly according to this CamcorderProfile.

The target video output bit rate in bits per second

 This is the target recorded video output bit rate if the application configures the video recording via MediaRecorder.setProfile without specifying any other MediaRecorder encoding parameters. For example, for high speed quality profiles (from QUALITY_HIGH_SPEED_LOW to QUALITY_HIGH_SPEED_2160P), this is the bit rate where the video is recorded with. If the application intends to record slow motion videos with the high speed quality profiles, it must set a different video bit rate that is corresponding to the desired recording output bit rate (i.e., the encoded video bit rate during normal playback) via MediaRecorder.setVideoEncodingBitRate. For example, if QUALITY_HIGH_SPEED_720P advertises 240fps videoFrameRate and 64Mbps videoBitRate in the high speed CamcorderProfile, and the application intends to record 1/8 factor slow motion recording videos, the application must set 30fps via MediaRecorder.setVideoFrameRate and 8Mbps ( videoBitRate * slow motion factor) via MediaRecorder.setVideoEncodingBitRate. Failing to do so will result in videos with unexpected frame rate and bit rate, or MediaRecorder error if the output bit rate exceeds the encoder limit. If the application intends to do the video recording with MediaCodec encoder, it must set each individual field of MediaFormat similarly according to this CamcorderProfile.

The target video frame rate in frames per second.

 This is the target recorded video output frame rate per second if the application configures the video recording via MediaRecorder.setProfile without specifying any other MediaRecorder encoding parameters. For example, for high speed quality profiles (from QUALITY_HIGH_SPEED_LOW to QUALITY_HIGH_SPEED_2160P), this is the frame rate where the video is recorded and played back with. If the application intends to create slow motion use case with the high speed quality profiles, it must set a different video frame rate that is corresponding to the desired output (playback) frame rate via MediaRecorder.setVideoFrameRate. For example, if QUALITY_HIGH_SPEED_720P advertises 240fps videoFrameRate in the CamcorderProfile, and the application intends to create 1/8 factor slow motion recording videos, the application must set 30fps via MediaRecorder.setVideoFrameRate. Failing to do so will result in high speed videos with normal speed playback frame rate (240fps for above example). If the application intends to do the video recording with MediaCodec encoder, it must set each individual field of MediaFormat similarly according to this CamcorderProfile.

        return native_get_camcorder_profile(cameraId, quality);
    }

    
Returns true if camcorder profile exists for the first back-facing
camera at the given quality level.

 When using the Camera 2 API in LEGACY mode (i.e. when CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL is set to CameraMetadata<Key<?>>.INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY), hasProfile may return true for unsupported resolutions. To ensure a a given resolution is supported in LEGACY mode, the configuration given in CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP must contain the the resolution in the supported output sizes. The recommended way to check this is with StreamConfigurationMap.getOutputSizes(Class<Object>) with the class of the desired recording endpoint, and check that the desired resolution is contained in the list returned. 


Params:
  • quality – the target quality level for the camcorder profile
