Contoh pekerjaan JSON transcoding yang dipercepat untuk AWS Elemental MediaConvert

Contoh pekerjaan JSON berikut mengonversi file MP4 ke file MP4 lain yang dikodekan 720p dengan H.265. Untuk menggunakan contoh ini, ganti pengaturan dengan nilai Anda. Minimal, Anda harus memberikan nilai untuk pengaturan berikut:

• Role: Ini adalah peran AWS Identity and Access Management (IAM) yang Anda atur untuk memberikan izin AWS MediaConvert Elemental untuk mengakses bucket Amazon S3 input dan output Anda dan untuk mengakses Amazon API Gateway atas nama Anda. Untuk informasi tentang mengatur peran ini, lihat Menyiapkan izin IAM di AWS Elemental MediaConvert Panduan Pengguna.

• Destination: Bucket Amazon S3 tempat Anda MediaConvert ingin menyimpan file output Anda. Pastikan untuk menyertakan garis miring terbalik, seperti pada contoh.

• InputClippings: Tentukan klip yang ingin Anda transkode dengan menentukan kumpulan nilai untuk dan. StartTimecode EndTimecode Atau, Anda dapat menghapus InputClippings seluruhnya untuk mentranskode seluruh aset.

• FileInput: Tentukan nama file dan lokasi untuk file input Anda. Masukan file Anda dapat berupa objek Amazon S3 atau URL HTTP.

  Transcoding yang dipercepat didukung dengan pekerjaan yang hanya memiliki satu input; Anda tidak dapat melakukan jahitan input.
