Device Information

To test this feature and view the example code, please see the Android SDK 5 Example Code Quick Start guide.

The CONNECT Player SDK provides static methods enabling you to retrieve device/decoder information to help the application avoid issues on devices. The OTVDecoderInfoUtil class contains four static methods to support retrieving audio and video decoder information and check if the specific audio/video OTVDecoderFormat can be supported.

The getVideoDecoderInfo method returns an array with all video decoders of H264/H265/AV1.
getAudioDecoderInfo returns an array with all audio decoders.
isVideoDecoderSupported checks if the specific OTVDecoderFormat is supported by video decoders in the system according to the information of MIME type and codec in OTVDecoderFormat.
isVideoDecoderSupported checks if the specific OTVDecoderFormat is supported by audio decoders in the system according to the information of MIME type information only in OTVDecoderFormat.

Devices connected to a TV monitor via HDMI may report differently, depending on the cable and monitor connected. For example, AC3 audio may be decoded either by the monitor or by the Android STB.

Retrieving video and audio decoder information

Query video information

JAVA

OTVVideoDecoderInfo[] videoDecoderInfos = OTVDecoderInfoUtil.getVideoDecoderInfo();
String videoDecoderName = videoDecoderInfos[0].decoderName;
String mimeType =  videoDecoderInfos[0].decoderMimeType;
int maxInstances = videoDecoderInfos[0].maxInstances;
Boolean isHardwareSupported = videoDecoderInfos[0].isHardwareSupported;
Pair<Integer,Integer> supportedMaxResolution = videoDecoderInfos[0].supportedMaxResolution;
//Get all profile and level values of first video decoder
Pair<Integer, Integer>[] profileLevels =  videoDecoderInfos[0].decoderProfileLevels;

The first value of the pair of profileLevels is profile, and the second value is level when getting the profile and level value of decoder. All integer values are defined in Android SDK.

Query audio information

JAVA

OTVAudioDecoderInfo[] audioDecoderInfos = OTVDecoderInfoUtil.getAudioDecoderInfo();
String audioDecoderName = audioDecoderInfos[0].decoderName;
String mimeType =  audioDecoderInfos[0].decoderMimeType;
int maxInstances = audioDecoderInfos[0].maxInstances;

Checking if the specific OTVDecoderFormat is supported

Video decoder

CODE

 OTVDecoderFormat decoderFormat = new OTVDecoderFormat("video/avc", "avc1.64001f");
 Boolean isSupported =  OTVDecoderInfoUtil.isAudioDecoderSupported(decoderFormat);

Audio decoder

CODE

 OTVDecoderFormat decoderFormat = new OTVDecoderFormat("audio/mp4", "mp4a.40.2");
 Boolean isSupported =  OTVDecoderInfoUtil.isAudioDecoderSupported(decoderFormat);
