Remarks
Query whether codec supports a given MediaFormat.
<p class=note> <strong>Note:</strong> On android.os.Build.VERSION_CODES#LOLLIPOP, format must not contain a MediaFormat#KEY_FRAME_RATE frame rate. Use format.setString(MediaFormat.KEY_FRAME_RATE, null) to clear any existing frame rate setting in the format.
The following table summarizes the format keys considered by this method. This is especially important to consider when targeting a higher SDK version than the minimum SDK version, as this method will disregard some keys on devices below the target SDK version.
