↳ | 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:
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; }
