MediaCodecInfo
extends Object
| java.lang.Object | |
| ↳ | android.media.MediaCodecInfo |
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:
Developers
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;
}

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.
