Method Detail

getSupportedMimeTypes

public static java.util.List<MimeType> getSupportedMimeTypes()

Returns a list of mime types for supported encoders. For each mime type in the list there is an encoder which you can use which supports it, and accepts the frames in YUV_420_Flexible format

getSystemSupportedEncoders

public static java.util.List<android.media.MediaCodecInfo> getSystemSupportedEncoders()

Returns:

list of encoders supported by the system

getSupportedEncoder

public static android.media.MediaCodecInfo getSupportedEncoder()

Tries to get a supported encoder. Defaults to h264 if supported, or otherwise returns any supported encoder by the media codec API. Currently for encoders to work with Kinesis Video they have to accept YUV_420_Flexible frames as input

Throws:

java.lang.RuntimeException - if no supported encoders are found

isHardwareAccelerated

public static boolean isHardwareAccelerated(android.media.MediaCodecInfo encoder)

Tries to guess whether the encoder is hardware accelerated.
