Isi JSON permintaan:

{
  "type": "RTMP_PUSH"
}

Untuk mengirim permintaan Anda, perluas salah satu opsi berikut:

curl (Linux, macOS, atau Cloud Shell)

Catatan: Perintah berikut mengasumsikan bahwa Anda telah login ke gcloud CLI menggunakan akun pengguna Anda dengan menjalankan gcloud init atau gcloud auth login , atau dengan menggunakan Cloud Shell, yang secara otomatis membuat Anda login ke gcloud CLI . Anda dapat memeriksa akun yang saat ini aktif dengan menjalankan gcloud auth list.

Simpan isi permintaan dalam file bernama request.json. Jalankan perintah berikut di terminal untuk membuat atau menimpa file ini di direktori saat ini:

cat > request.json << 'EOF'
{
  "type": "RTMP_PUSH"
}
EOF

Kemudian jalankan perintah berikut untuk mengirim permintaan REST Anda:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \

    "verb": "create",
    "requestedCancellation": false,
    "apiVersion": "v1"
  },
  "done": false
}

Salin OPERATION_ID yang ditampilkan untuk digunakan di bagian berikutnya.

Periksa hasilnya

Gunakan metode projects.locations.operations.get untuk memeriksa apakah endpoint input telah dibuat. Jika respons berisi "done: false", ulangi perintah hingga respons berisi "done: true". Membuat endpoint input pertama di suatu region dapat memerlukan waktu hingga 10 menit.

    "tier": "HD"
  }
}

Temukan kolom uri dan salin INPUT_STREAM_URI yang ditampilkan untuk digunakan nanti di bagian Kirimkan aliran input.

Buat channel

Untuk membuat saluran, gunakan metode projects.locations.channels.create.

Perhatikan hal berikut dalam konfigurasi saluran:

ElementaryStream, TextStream, digunakan untuk teks.

{
  "key": "webvtt_english_ai",
  "textStream": {
    "codec": "webvtt",
    "displayName": "English (AI captioned)",
    "languageCode": "en-US",
    "mapping": [
      {
        "inputTrack": 1 // audio track number
      }
    ]
  }
}

Kolom TextStream codec harus ditetapkan ke webvtt.
Kolom TextStream mapping menggunakan inputTrack untuk menetapkan trek audio input yang akan digunakan untuk membuat teks. Pemetaan tidak boleh menyertakan kolom inputCeaChannel, yang hanya digunakan untuk teks tertutup yang disediakan pengguna.
Setel languageCode ke bahasa yang digunakan dalam trek audio.

Aliran elementer digunakan untuk membuat MuxStream dengan kunci vtt_english_ai.

{
  "key": "vtt_english_ai",
  "container": "vtt",
  "elementaryStreams": [
    "webvtt_english_ai"
  ],
  "segmentSettings": {
    "segmentDuration": "2s"
  }
}

Kemudian, stream mux ini dirujuk dalam manifes HLS dan DASH.

{
  "fileName": "main.m3u8",
  "type": "HLS",
  "muxStreams": [
    "mux_video_ts",
    "vtt_english_ai"
  ],
  "maxSegmentCount": 5
}

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

PROJECT_NUMBER: nomor Google Cloud project Anda; nomor ini ada di kolom Project number di halaman IAM Settings
LOCATION: lokasi tempat membuat channel; gunakan salah satu region yang didukung

Respons ini menunjukkan bahwa Anda kini dapat memulai channel.

Mulai channel

Gunakan metode projects.locations.channels.start untuk memulai channel. Channel harus dimulai sebelum dapat menerima aliran input atau membuat aliran output.

Memulai channel pertama di suatu region memerlukan waktu sekitar 10 menit.

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

PROJECT_NUMBER: nomor Google Cloud project Anda; nomor ini ada di kolom Project number di halaman IAM Settings
LOCATION: lokasi tempat channel Anda berada; gunakan salah satu region yang didukung
Tampilkan lokasi
- us-central1
- us-east1
- us-east4

- asia-east1
- asia-east2
- asia-south1
- asia-northeast1
- asia-southeast1
- australia-southeast1
- europe-north1
- europe-west1
- europe-west2
- europe-west3

curl (Linux, macOS, atau Cloud Shell)

Jalankan perintah berikut:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d "" \
     "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/channels/CHANNEL_ID:start"

PowerShell (Windows)

Jalankan perintah berikut:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/channels/CHANNEL_ID:start" | Select-Object -Expand Content

Anda akan menerima respons JSON yang mirip dengan yang berikut ini:

    "verb": "start",
    "requestedCancellation": false,
    "apiVersion": "v1"
  },
  "done": false
}

Untuk menentukan apakah channel telah dimulai, dapatkan informasi channel seperti yang dilakukan sebelumnya. Respons harus berisi hal berikut:

{
  ...
  "streamingState": "AWAITING_INPUT"
  ...
}

Kirimkan aliran input

Setelah channel siap, kirim aliran input ke endpoint input untuk membuat live stream. Anda dapat mendownload MP4 (atau TEST_VOD_FILE lainnya) dengan teks dan menggunakan ffmpeg untuk mengirimkannya ke endpoint input.

Buka jendela terminal baru. Jalankan perintah berikut, menggunakan INPUT_STREAM_URI dari bagian Periksa hasilnya:

ffmpeg -re -stream_loop -1 -i "TEST_VOD_FILE" \
  -c:v copy -c:a aac -strict 2 -f "flv" "INPUT_STREAM_URI"

Verifikasi teks dalam manifes output

Jalankan perintah berikut untuk melihat isi manifes HLS yang dihasilkan:

gcloud storage cat gs://BUCKET_NAME/main.m3u8

Teks bahasa Inggris webvtt yang dibuat AI muncul di manifes output mirip dengan berikut ini:

#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="sub",LANGUAGE="en-US",NAME="English (AI captioned)",AUTOSELECT=YES,DEFAULT=YES,FORCED=NO,URI="vtt_english_ai/index-1.m3u8"

Menghentikan channel

Anda harus menghentikan channel sebelum memperbarui konfigurasi channel.

Gunakan metode projects.locations.channels.stop untuk menghentikan saluran.

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

PROJECT_NUMBER: nomor Google Cloud project Anda; nomor ini ada di kolom Project number di halaman IAM Settings

Memperbarui konfigurasi channel untuk terjemahan

Perbarui konfigurasi channel untuk menyertakan teks terjemahan (yaitu, terjemahan).

Perhatikan penambahan berikut pada konfigurasi channel:

Satu ElementaryStream, TextStream, digunakan untuk teks dalam satu bahasa terjemahan.

{
  "key": "webvtt_spanish_ai",
  "textStream": {
    "codec": "webvtt",
    "displayName": "Spanish (AI captioned)",
    "languageCode": "es-MX",
    "mapping": [
      {
        "inputTrack": 1, // audio track number
        "fromLanguageCode": "en-US" // original audio in English
      }
    ]
  }
}

Tetapkan languageCode ke bahasa terjemahan yang dipilih.
Setel fromLanguageCode ke bahasa sumber asli dalam trek audio.

Aliran elementer digunakan untuk membuat MuxStream dengan kunci vtt_spanish_ai.

{
  "key": "vtt_spanish_ai",
  "container": "vtt",
  "elementaryStreams": [
    "webvtt_spanish_ai"
  ],
  "segmentSettings": {
    "segmentDuration": "2s"
  }
}

Kemudian, stream mux ini dirujuk dalam manifes HLS dan DASH.

{
  "fileName": "main.m3u8",
  "type": "HLS",
  "muxStreams": [
    "mux_video_ts",
    "vtt_english_ai",
    "vtt_spanish_ai"
  ],
  "maxSegmentCount": 5
}

Untuk memperbarui saluran, gunakan metode projects.locations.channels.patch.

Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:

PROJECT_NUMBER: nomor Google Cloud project Anda; nomor ini ada di kolom Project number di halaman IAM Settings
LOCATION: lokasi tempat membuat channel; gunakan salah satu region yang didukung
Tampilkan lokasi
- us-central1
- us-east1

Anda dapat memeriksa hasil operasi menggunakan ID operasi baru.

Mulai ulang channel dan kirim ulang aliran input

Seperti yang dilakukan sebelumnya, mulai channel dan kirimkan input stream lagi.

Verifikasi terjemahan dalam manifes output

Jalankan perintah berikut untuk melihat isi manifes HLS yang dihasilkan:

gcloud storage cat gs://BUCKET_NAME/main.m3u8

Teks bahasa Inggris dan Spanyol yang dibuat AI akan muncul dalam manifes output yang mirip dengan berikut ini:

#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="sub",LANGUAGE="en-US",NAME="English (AI captioned)",AUTOSELECT=YES,DEFAULT=YES,FORCED=NO,URI="vtt_english_ai/index-1.m3u8"
#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="sub",LANGUAGE="es-MX",NAME="Spanish (AI captioned)",AUTOSELECT=NO,DEFAULT=NO,FORCED=NO,URI="vtt_spanish_ai/index-1.m3u8"

Mengonfigurasi transkrip buatan AI untuk distribusi

Sebelum mengonfigurasi teks dan terjemahan buatan AI untuk distribusi, pahami cara mendistribusikan live stream ke endpoint jarak jauh.

Untuk mendistribusikan teks dan terjemahan yang dibuat AI ke endpoint jarak jauh, jangan merujuk ke aliran teks dalam format webvtt yang dikonfigurasi sebelumnya saat membuat channel dengan teks yang dibuat AI dan memperbarui channel untuk terjemahan. Aliran teks untuk distribusi harus berupa teks tertanam, dengan codec disetel ke cea608 atau cea708.

Dalam konfigurasi saluran, pertimbangkan hal berikut:

ElementaryStream, TextStream, digunakan untuk teks, dan ElementaryStream, TextStream, digunakan untuk terjemahan.

{
  "key": "embedded_english_ai",
  "textStream": {
    "codec": "cea608",
    "displayName": "English (AI captioned)",
    "languageCode": "en-US",
    "outputCeaChannel": "CC1", // closed caption channel that will contain AI-generated English captions
    "mapping": [
      {
        "inputTrack": 1 // audio track number
      }
    ]
  }
}

{
  "key": "embedded_spanish_ai",
  "textStream": {
    "codec": "cea608",
    "displayName": "Spanish (AI captioned)",
    "languageCode": "es-MX",
    "outputCeaChannel": "CC2", // closed caption channel that will contain AI-generated Spanish captions
    "mapping": [
      {
        "inputTrack": 1, // audio track number
        "fromLanguageCode": "en-US" // original audio in English
      }
    ]
  }
}

Kolom TextStream codec harus ditetapkan ke cea608 atau cea708.
Kolom TextStream mapping menggunakan inputTrack untuk menetapkan trek audio input yang akan digunakan untuk membuat teks. Pemetaan tidak boleh menyertakan kolom inputCeaChannel, yang hanya digunakan untuk teks tertutup yang disediakan pengguna.
Setel outputCeaChannel ke saluran teks tertutup untuk memuat transkrip buatan AI dalam streaming distribusi.
Setel languageCode ke bahasa yang digunakan dalam trek audio.

Aliran elementer disertakan dalam kolom elementaryStreams objek DistributionStream.

{
  "distributionStreams": [
    {
      "key": "ds1",
      "container": "ts", // to be used with an SRT distribution
      "elementaryStreams": [
        "es_video",
        "es_audio",
        "embedded_english_ai", // distribute both English
        "embedded_spanish_ai"  // and Spanish captions
      ]
    },
    {
      "key": "ds2",
      "container": "flv", // to be used with an RTMP distribution
      "elementaryStreams": [
        "es_video",
        "es_audio",
        "embedded_spanish_ai" // only distribute Spanish captions
      ]
    }
  ]
}

Selesaikan pembuatan channel dengan mengikuti panduan mendistribusikan live stream ke endpoint jarak jauh.

Konfigurasi lanjutan

Tetapkan AutoTranscriptionConfig di tingkat channel untuk lebih menyetel aliran teks buatan AI sesuai kebutuhan Anda.

Pengaturan waktu tampilan teks

Secara default, teks buatan AI ditampilkan secara asinkron dengan audio dan video. Tetapkan kolom DisplayTiming di AutoTranscriptionConfig ke SYNC untuk menampilkannya secara serentak.

{
  "autoTranscriptionConfig": {
    "displayTiming": "SYNC"
  }
}

Menampilkan teks secara sinkron akan mengurangi latensi penayangan antara audio dan teks, tetapi meningkatkan latensi media end-to-end secara keseluruhan.

Preset kualitas

Gunakan kolom QualityPreset di AutoTranscriptionConfig untuk mengonfigurasi preferensi kualitas untuk aliran teks yang dibuat AI.

Misalnya, Anda dapat mengurangi lebih lanjut latensi pembuatan aliran teks dengan menyetel:

{
  "autoTranscriptionConfig" : {
    "qualityPreset": "LOW_LATENCY"
  }
}

Pembersihan

Menghentikan channel

Gunakan metode projects.locations.channels.stop untuk menghentikan saluran. Anda harus menghentikan channel sebelum dapat menghapusnya.
