示例1: onOutputFormatChanged
import android.media.MediaCodec; //導入方法依賴的package包/類
@Override
protected void onOutputFormatChanged(MediaCodec codec, android.media.MediaFormat outputFormat) {
boolean hasCrop = outputFormat.containsKey(KEY_CROP_RIGHT)
&& outputFormat.containsKey(KEY_CROP_LEFT) && outputFormat.containsKey(KEY_CROP_BOTTOM)
&& outputFormat.containsKey(KEY_CROP_TOP);
currentWidth = hasCrop
? outputFormat.getInteger(KEY_CROP_RIGHT) - outputFormat.getInteger(KEY_CROP_LEFT) + 1
: outputFormat.getInteger(android.media.MediaFormat.KEY_WIDTH);
currentHeight = hasCrop
? outputFormat.getInteger(KEY_CROP_BOTTOM) - outputFormat.getInteger(KEY_CROP_TOP) + 1
: outputFormat.getInteger(android.media.MediaFormat.KEY_HEIGHT);
currentPixelWidthHeightRatio = pendingPixelWidthHeightRatio;
if (Util.SDK_INT >= 21) {
// On API level 21 and above the decoder applies the rotation when rendering to the surface.
// Hence currentUnappliedRotation should always be 0. For 90 and 270 degree rotations, we need
// to flip the width, height and pixel aspect ratio to reflect the rotation that was applied.
if (pendingRotationDegrees == 90 || pendingRotationDegrees == 270) {
int rotatedHeight = currentWidth;
currentWidth = currentHeight;
currentHeight = rotatedHeight;
currentPixelWidthHeightRatio = 1 / currentPixelWidthHeightRatio;
}
} else {
// On API level 20 and below the decoder does not apply the rotation.
currentUnappliedRotationDegrees = pendingRotationDegrees;
}
// Must be applied each time the output format changes.
codec.setVideoScalingMode(videoScalingMode);
}
示例2: setVideoScalingMode
import android.media.MediaCodec; //導入方法依賴的package包/類
private static void setVideoScalingMode(MediaCodec codec, int scalingMode) {
codec.setVideoScalingMode(scalingMode);
}
