getBitrate
public int getBitrate ()
The target video output bitrate in bits per second
This is the target recorded video output bitrate 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 CamcorderProfile#QUALITY_HIGH_SPEED_LOW to CamcorderProfile.QUALITY_HIGH_SPEED_2160P), this is the bitrate 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 bitrate that is corresponding to
the desired recording output bit rate (i.e., the encoded video bitrate during normal
playback) via MediaRecorder#setVideoEncodingBitRate. For example, if CamcorderProfile.QUALITY_HIGH_SPEED_720P advertises 240fps getFrameRate() and
64Mbps getBitrate() in the high speed VideoProfile, and the application
intends to record 1/8 factor slow motion recording videos, the application must set 30fps
via MediaRecorder#setVideoFrameRate and 8Mbps ( getBitrate() * 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 VideoProfile.

getFrameRate
public int getFrameRate ()
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 CamcorderProfile#QUALITY_HIGH_SPEED_LOW to CamcorderProfile.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(int). For example, if CamcorderProfile.QUALITY_HIGH_SPEED_720P advertises 240fps getFrameRate()
in the VideoProfile, and the application intends to create 1/8 factor slow motion
recording videos, the application must set 30fps via MediaRecorder.setVideoFrameRate(int). 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 VideoProfile.

getHeight
public int getHeight ()
The target video frame height in pixels
| Returns | |

This value cannot be null. |
