MediaCodecInfo
public
final
class
MediaCodecInfo
extends Object
Provides information about a given media codec available on the device. You can
iterate through all codecs available by querying MediaCodecList. For example,
here's how to find an encoder that supports a given MIME type:
private static MediaCodecInfo selectCodec(String mimeType) {
int numCodecs = MediaCodecList.getCodecCount();
for (int i = 0; i < numCodecs; i++) {
MediaCodecInfo codecInfo = MediaCodecList.getCodecInfoAt(i);
if (!codecInfo.isEncoder()) {
continue;
}
String[] types = codecInfo.getSupportedTypes();
for (int j = 0; j < types.length; j++) {
if (types[j].equalsIgnoreCase(mimeType)) {
return codecInfo;
}
}
}
return null;
}

Public methods
getCapabilitiesForType
public MediaCodecInfo.CodecCapabilities getCapabilitiesForType (String type)
Enumerates the capabilities of the codec component. Since a single
component can support data of a variety of types, the type has to be
specified to yield a meaningful result.
| Parameters |
|---|
type |
String: The MIME type to query
|
getName
public String getName ()
Retrieve the codec name.
getSupportedTypes
public String[] getSupportedTypes ()
Query the media types supported by the codec.
isEncoder
public boolean isEncoder ()
Query if the codec is an encoder.
