Android 获取系统编解码器

article 2024/11/16 3:37:53

媒体编解码器 官网说明。

通过 MediaCodecInfo 拿到解码器信息：

  • getName() ：获取编解码器名字。
  • isEncoder() ：如果是编码器返回 true 。如果是编码器，返回 false 。
  • isHardwareAccelerated() ：如果是硬解码返回 true 。
  • isVendor() ：如果编解码器由设备供应商提供，则返回 true；如果由 Android 平台提供，则返回 false。
  • getSupportedTypes() ：获取支持的媒体类型。
import android.media.MediaCodecInfo;
import android.media.MediaCodecList;

    private void MediaCodecInfo(){
        MediaCodecList list = null;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            list = new MediaCodecList(MediaCodecList.REGULAR_CODECS);
            MediaCodecInfo[] supportCodes = list.getCodecInfos();
            if (null != supportCodes && supportCodes.length > 0) {
                for (MediaCodecInfo info : supportCodes){
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                        StringBuilder strTypes = new StringBuilder();
                        String[] types = info.getSupportedTypes();
                        for (int j = 0; j < types.length; j++) {
                            strTypes.append(types[j]).append(",");
                        }
                        Log.d(TAG , "[MainActivity] -- MediaCodecInfo -- "
                                + "find MediaCodecInfo " + info.getName()
                                + " , isEncoder:" + info.isEncoder()
                                + " , isHardwareAccelerated:" + info.isHardwareAccelerated()
                                + " , isVendor:" + info.isVendor()
                                + " , supportedTypes:" + strTypes);
                    }
                }
            }
        }
    }
