HDR, atau Rentang Dinamis Tinggi, memberikan rentang warna yang lebih luas dan kontras yang lebih besar antara warna putih paling terang dan bayangan paling gelap, sehingga menghasilkan kualitas video yang lebih menyerupai apa yang dilihat mata telanjang.
Anda dapat menyiapkan pemutaran video HDR di aplikasi untuk melihat pratinjau dan memutar kembali konten video HDR.
Artikel ini mengasumsikan bahwa Anda telah menambahkan dukungan pemutaran video dasar ke aplikasi Anda. Lihat dokumentasi ExoPlayer untuk mengetahui detail selengkapnya tentang pemutaran.
Prasyarat perangkat
Tidak semua perangkat Android mendukung pemutaran HDR. Sebelum memutar konten video HDR di aplikasi Anda, tentukan apakah perangkat Anda memenuhi prasyarat berikut:
Menargetkan Android 7.0 atau yang lebih tinggi (lapisan API 24).
Memiliki decoder yang kompatibel dengan HDR dan akses ke layar yang kompatibel dengan HDR.
Memeriksa dukungan pemutaran HDR
Gunakan Display.getHdrCapabilities() untuk mengkueri kemampuan HDR layar. Metode ini menampilkan informasi tentang profil HDR dan rentang luminans yang didukung untuk layar.
Kode berikut memeriksa apakah perangkat mendukung pemutaran HLG10. Mulai Android 13, HLG10 adalah standar minimum yang harus didukung oleh produsen perangkat jika perangkat tersebut mampu memutar HDR:
Kotlin
// Check if display supports the HDR typevalcapabilities=display?.hdrCapabilities?.supportedHdrTypes?:intArrayOf()if(!capabilities.contains(HDR_TYPE_HLG)){throwRuntimeException("Display does not support desired HDR type");}
Java
// Check if display supports the HDR typeint[]list=getDisplay().getHdrCapabilities().getSupportedHdrTypes();Listcapabilities=Arrays.stream(list).boxed().collect(Collectors.toList());if(!capabilities.contains(HDR_TYPE_HLG)){thrownewRuntimeException("Display does not support desired HDR type");}
Menyiapkan pemutaran HDR di aplikasi Anda
Jika aplikasi Anda menggunakan ExoPlayer, aplikasi tersebut mendukung pemutaran HDR secara default. Lihat Memeriksa dukungan pemutaran HDR untuk mengetahui langkah berikutnya.
Jika aplikasi Anda tidak menggunakan ExoPlayer, siapkan pemutaran HDR menggunakan MediaCodec melalui SurfaceView.
Menyiapkan MediaCodec menggunakan SurfaceView
Siapkan alur pemutaran MediaCodec standar menggunakan SurfaceView. Hal ini memungkinkan Anda menampilkan konten video HDR tanpa penanganan khusus untuk pemutaran HDR:
MediaCodec: Mendekode konten video HDR.
SurfaceView: Menampilkan konten video HDR.
Kode berikut memeriksa apakah codec mendukung profil HDR, lalu menyiapkan MediaCodec menggunakan SurfaceView:
Kotlin
// Check if there's a codec that supports the specific HDR profilevallist=MediaCodecList(MediaCodecList.REGULAR_CODECS)varformat=MediaFormat()/* media format from the container */;format.setInteger(MediaFormat.KEY_PROFILE,MediaCodecInfo.CodecProfileLevel.AV1ProfileMain10)valcodecName=list.findDecoderForFormat(format)?:throwRuntimeException("No codec supports the format")// Here is a standard MediaCodec playback flowvalcodec:MediaCodec=MediaCodec.createByCodecName(codecName);valsurface:Surface=surfaceView.holder.surfacevalcallback:MediaCodec.Callback=(object:MediaCodec.Callback(){overridefunonInputBufferAvailable(codec:MediaCodec,index:Int){queue.offer(index)}overridefunonOutputBufferAvailable(codec:MediaCodec,index:Int,info:MediaCodec.BufferInfo){codec.releaseOutputBuffer(index,timestamp)}overridefunonError(codec:MediaCodec,e:MediaCodec.CodecException){// handle error}overridefunonOutputFormatChanged(codec:MediaCodec,format:MediaFormat){// handle format change}})codec.setCallback(callback)codec.configure(format,surface,crypto,0/* flags */)codec.start()while(/* until EOS */){valindex=queue.poll()valbuffer=codec.getInputBuffer(index)buffer?.put(/* write bitstream */)codec.queueInputBuffer(index,offset,size,timestamp,flags)}codec.stop()codec.release()
Java
// Check if there's a codec that supports the specific HDR profileMediaCodecListlist=newMediaCodecList(MediaCodecList.REGULAR_CODECS);MediaFormatformat=/* media format from the container */;format.setInteger(MediaFormat.KEY_PROFILE,CodecProfileLevel.AV1ProfileMain10);StringcodecName=list.findDecoderForFormat(format);if(codecName==null){thrownewRuntimeException("No codec supports the format");}// Below is a standard MediaCodec playback flowMediaCodeccodec=MediaCodec.getCodecByName(codecName);Surfacesurface=surfaceView.getHolder().getSurface();MediaCodec.Callbackcallback=newMediaCodec.Callback(){@OverridevoidonInputBufferAvailable(MediaCodeccodec,intindex){queue.offer(index);}@OverridevoidonOutputBufferAvailable(MediaCodeccodec,intindex){// release the buffer for rendercodec.releaseOutputBuffer(index,timestamp);}@OverridevoidonOutputFormatChanged(MediaCodeccodec,MediaFormatformat){// handle format change}@OverridevoidonError(MediaCodeccodec,MediaCodec.CodecExceptionex){// handle error}};codec.setCallback(callback);codec.configure(format,surface,crypto,0/* flags */);codec.start();while(/* until EOS */){intindex=queue.poll();ByteBufferbuffer=codec.getInputBuffer(index);buffer.put(/* write bitstream */);codec.queueInputBuffer(index,offset,size,timestamp,flags);}codec.stop();codec.release();

Before playing back HDR\nvideo content in your app, determine if your device meets the following\nprerequisites:\n\n- Targets Android 7.0 or higher (API layer 24).\n- Has a HDR-capable decoder and access to a HDR-capable display.\n\nCheck for HDR playback support\n------------------------------\n\nUse [`Display.getHdrCapabilities()`](/reference/android/view/Display#getHdrCapabilities()) to query a display's HDR capabilities. The method returns information about the supported HDR profiles and luminance range for the display.\n\nThe following code checks if the device supports HLG10 playback. Starting in Android 13, HLG10 is the minimum standard that device makers must support if the device is capable of HDR playback: \n\n### Kotlin\n\n```kotlin\n// Check if display supports the HDR type\nval capabilities = display?.hdrCapabilities?.supportedHdrTypes ?: intArrayOf()\nif (!capabilities.contains(HDR_TYPE_HLG)) {\n throw RuntimeException(\"Display does not support desired HDR type\");\n}\n```\n\n### Java\n\n```java\n// Check if display supports the HDR type\nint[] list = getDisplay().getHdrCapabilities().getSupportedHdrTypes();\nList capabilities = Arrays.stream(list).boxed().collect(Collectors.toList());\nif (!capabilities.contains(HDR_TYPE_HLG)) {\n throw new RuntimeException(\"Display does not support desired HDR type\");\n}\n```\n\nSet up HDR playback in your app\n-------------------------------\n\nIf your app uses [ExoPlayer](https://exoplayer.dev/), it supports HDR playback by default. See [Check for HDR playback support](#check_for_hdr_playback_support) for next steps.\n\nIf your app does not use ExoPlayer, set up HDR playback using `MediaCodec` via `SurfaceView`.\n| **Note:** HDR playback has limited support on [`TextureView`](/reference/android/view/TextureView) in Android 13 (API layer 33) and higher. When playing back HDR video content, `TextureView` transcodes the video from HDR to SDR, resulting in playback with possible loss of detail including clipped colors and video banding. If at all possible, you should use `SurfaceView` for HDR playback.\n\n### Set up MediaCodec using SurfaceView\n\nSet up a standard [`MediaCodec`](/reference/android/media/MediaCodec) playback flow using [`SurfaceView`](https://developer.android.com/reference/android/view/SurfaceView). This allows you to display HDR video content without any special handling for HDR playback:\n\n- `MediaCodec`: Decodes HDR video content.\n- `SurfaceView`: Displays HDR video content.\n\nThe following code checks if the codec supports the HDR profile, then sets up `MediaCodec` using `SurfaceView`: \n\n### Kotlin\n\n```kotlin\n// Check if there's a codec that supports the specific HDR profile\nval list = MediaCodecList(MediaCodecList.REGULAR_CODECS) var format = MediaFormat() /* media format from the container */;\nformat.setInteger(MediaFormat.KEY_PROFILE, MediaCodecInfo.CodecProfileLevel.AV1ProfileMain10)\nval codecName = list.findDecoderForFormat (format) ?: throw RuntimeException (\"No codec supports the format\")\n\n// Here is a standard MediaCodec playback flow\nval codec: MediaCodec = MediaCodec.createByCodecName(codecName);\nval surface: Surface = surfaceView.holder.surface\nval callback: MediaCodec.Callback = (object : MediaCodec.Callback() {\n override fun onInputBufferAvailable(codec: MediaCodec, index: Int) {\n queue.offer(index)\n }\n\n override fun onOutputBufferAvailable(\n codec: MediaCodec,\n index: Int,\n info: MediaCodec.BufferInfo\n ) {\n codec.releaseOutputBuffer(index, timestamp)\n }\n\n override fun onError(codec: MediaCodec, e: MediaCodec.CodecException) {\n // handle error\n }\n\n override fun onOutputFormatChanged(\n codec: MediaCodec, format: MediaFormat\n ) {\n // handle format change\n }\n})\n\ncodec.setCallback(callback)\ncodec.configure(format, surface, crypto, 0 /* flags */)\ncodec.start()\nwhile (/* until EOS */) {\n val index = queue.poll()\n val buffer = codec.getInputBuffer(index)\n buffer?.put(/* write bitstream */)\n codec.queueInputBuffer(index, offset, size, timestamp, flags)\n}\ncodec.stop()\ncodec.release()\n```\n\n### Java\n\n```java\n// Check if there's a codec that supports the specific HDR profile\nMediaCodecList list = new MediaCodecList(MediaCodecList.REGULAR_CODECS);\nMediaFormat format = /* media format from the container */;\nformat.setInteger(\n MediaFormat.KEY_PROFILE, CodecProfileLevel.AV1ProfileMain10);\nString codecName = list.findDecoderForFormat(format);\nif (codecName == null) {\n throw new RuntimeException(\"No codec supports the format\");\n}\n\n// Below is a standard MediaCodec playback flow\nMediaCodec codec = MediaCodec.getCodecByName(codecName);\nSurface surface = surfaceView.getHolder().getSurface();\nMediaCodec.Callback callback = new MediaCodec.Callback() {\n @Override\n void onInputBufferAvailable(MediaCodec codec, int index) {\n queue.offer(index);\n }\n\n @Override\n void onOutputBufferAvailable(MediaCodec codec, int index) {\n // release the buffer for render\n codec.releaseOutputBuffer(index, timestamp);\n }\n\n @Override\n void onOutputFormatChanged(MediaCodec codec, MediaFormat format) {\n // handle format change\n }\n\n @Override\n void onError(MediaCodec codec, MediaCodec.CodecException ex) {\n // handle error\n }\n\n};\ncodec.setCallback(callback);\ncodec.configure(format, surface, crypto, 0 /* flags */);\ncodec.start();\nwhile (/* until EOS */) {\n int index = queue.poll();\n ByteBuffer buffer = codec.getInputBuffer(index);\n buffer.put(/* write bitstream */);\n codec.queueInputBuffer(index, offset, size, timestamp, flags);\n}\ncodec.stop();\ncodec.release();\n```\n\nFor more `MediaCodec` implementations using `SurfaceView`, see the [Android Camera samples](https://github.com/android/camera-samples).\n| **Note:** Android takes screenshots in SDR. HDR content is tonemapped to SDR in screenshots.\n\nResources\n---------\n\nFor more information related to HDR playback, see the following resources:\n\n### HDR\n\n- [HDR video capture](/training/camera2/hdr-video-capture): learn how to set up HDR video capture using the Camera2 APIs.\n- [Camera2Video sample on Github](https://github.com/android/camera-samples/tree/main/Camera2Video): see a working app with HDR capture and playback functionality.\n\n### Media\n\n- [Media API reference](/reference/android/media/package-summary): learn more about the Media APIs.\n- [ExoPlayer](https://exoplayer.dev/): learn how to set up your app with the ExoPlayer library."]]
