Drive and Photo Service:Value-added billable items

Audio and video transcoding

• The default interface uses LiveTranscoding for playback. Transcoding service is not triggered if the video is not played.

• Transcoded videos use the H.264 encoder by default.

• The resolution of transcoded videos is determined by the source video resolution. The default transcoding resolution is ≤(1920 × 1080). For higher definition services, please contact us.

• Transcoded data is saved to the tenant Domain's value-added data space for end users to play audio and video online. Transcoded data generates storage volume and storage fees. Storage fees are related to the amount of data generated by transcoding. For unit prices, see Basic billable items.

LiveTranscoding

• Fee composition:

  • Billable items generated when creating playlists: Billable item and Billable item, where LiveTranscoding is generated during initial transcoding. The initial transcoding duration can be controlled using the InitialTranscode parameter.

  • Billable items generated when playing videos: Billable item (only generated when playing and triggering actual transcoding of TS files).

  • Fees generated on the OSS side: fees generated by reading source videos from Object Storage Service (OSS) for transcoding and writing transcoded video files to OSS and by reading video files from OSS for video playback. For details about OSS fees, see OSS Billable items.

• Metering rules for LiveTranscoding billing:

  • Video

    • The efficiency (referred to as eff in the following formula) for different video output codecs: H.264: 0.3, H.265: 1.8.

    • Calculation formula:

  Ceiling (eff * Ceiling(Height/240) * Ceiling(Width/240) * Ceiling(FrameRate/30) + 1 ) * Ceiling(VideoStreamDuration) .

  • Audio

    • The efficiency (eff) is 0.3

    • Calculation formula:

  Ceiling(eff * Ceiling(AudioStreamDuration)).

• Billing rules: Each processed video stream (specified by TargetVideo.Stream) and each processed audio stream (specified by TargetAudio.Stream) are separately billed. A billing example is provided for each of the following billing rules to help you understand LiveTranscoding billing:

  • Example 1 (No fee for the LiveTranscoding billable item is generated if no video in a generated playlist is played):

    • You call the GenerateVideoPlaylist operation with InitialTranscode set to 0 and TranscodeAhead left empty to create a video playlist for a 38-minute H.264 output video at a resolution of 800 × 600 pixels and a frame rate of 30 fps. No video in the playlist is played.

    • The fee for the following billable item is generated: MediaMeta: The operation generates a fee for the MediaMeta billable item only once.

  • Example 2 (A fee for the LiveTrancoding billable item for initial transcoding is generated if a generated playlist has an initial transcoding configuration and no video in the playlist is played):

    • You call the GenerateVideoPlaylist operation with InitialTranscode set to 30 and TranscodeAhead left empty to create a video playlist for a 38-minute H.264 output video at a resolution of 800 × 600 pixels and a frame rate of 30 fps. No video in the playlist is played.

    • The fees for the following billable items are generated:

      • MediaMeta: The operation generates a fee for the MediaMeta billable item only once.

      • LiveTranscoding (CU calculation formula): Ceiling((0.3 * Ceiling(800/240) * Ceiling(600/240) * Ceiling(30/30) + 1 ) * (Ceiling(30)) + Ceiling(0.3 * Ceiling(30)) = 159 (CountUnit).

  • Example 3 (A fee for the LiveTranscoding billable item is generated for the played segments of video content in a generated playlist):

    • You call the GenerateVideoPlaylist operation with InitialTranscode set to 0 and TranscodeAhead left empty to create a video playlist for a 38-minute H.264 output video at a resolution of 800 × 600 pixels and a frame rate of 30 fps. Then, you play the video from the beginning to the 5th minute (transcoded to 2 minutes ahead by default) and skip to the 15th minute, from which the playback continues to the end.

    • The fees for the following billable items are generated:

      • MediaMeta: The operation generates a fee for the MediaMeta billable item only once.

      • LiveTranscoding (CU calculation formula): Ceiling((0.3 * Ceiling(800/240) * Ceiling(600/240) * Ceiling(30/30) + 1) * (Ceiling((5+2)*60) + Ceiling((38-15)*60)) + Ceiling(0.3 * Ceiling((5+2) * 60)) + Ceiling(0.3 * Ceiling((38-15) * 60) = 9540 (CountUnit).

  • Example 4 (A fee for the LiveTranscoding billable item is generated only once if the video is played by multiple users):

    • You call the GenerateVideoPlaylist operation with InitialTranscode set to 0 and TranscodeAhead left empty to create a video playlist for a 38-minute H.264 output video at a resolution of 800 × 600 pixels and a frame rate of 30 fps.

      User A uses the playlist to play the video from the beginning to the 5th minute and then exits playback.

      User B uses the playlist to play the video starting from the 15th minute to the end.

      User C uses the playlist to play the video from the beginning to the end.

    • The fees for the following billable items are generated:

      • MediaMeta: The operation generates a fee for the MediaMeta billable item only once.

      • LiveTranscoding (CU calculation formula): Ceiling((0.3 * Ceiling(800/240) * Ceiling(600/240) * Ceiling(30/30) + 1) * Ceiling(38*60) + Ceiling(0.3 * Celling(38 * 60)) = 12084 (CountUnit).

• Terms:

  • Width: The width of the output video resolution.

  • Height: The height of the output video resolution.

  • FrameRate: The video frame rate.

  • VideoStreamDuration: The length of the video stream.

  • AudioStreamDuration: The length of the audio stream.

  • eff: The CU coefficient.

  • Ceiling(x) function: Returns the smallest integer value that is greater than or equal to x.
