    How do I configure a media workflow?

    The steps are as follows:
    Step 1. Create a workflow
    Log in to the CI console, click Bucket Management, and click Manage in the Operation column on the right of the target bucket to enter the bucket management page.
    Click Job and Workflow on the left sidebar, click Create Workflow, and configure the following information:
    Step 2. Manage the workflow
    You can view the list of created workflows on the workflow management page.
    Step 3. View the workflow execution instance
    An execution instance will be generated after a workflow is executed for each video file. The execution instance page displays the source file address, workflow execution status, and execution time.
    Step 4. Test the workflow
    After a workflow is created, it can be automatically triggered for files uploaded to the specified bucket or manually triggered for existing files in the bucket.
    Currently, workflows can process 3GP, ASF, AVI, DV, FLV, F4V, M3U8, M4V, MKV, MOV, MP4, MPG, MPEG, MTS, OGG, RM, RMVB, SWF, VOB, WMV, WEBM, MP3, AAC, FLAC, AMR, M4A, WMA, and WAV files. When initiating a media processing request, you must enter the complete file name and extension; otherwise, the format cannot be recognized and processed.
    Currently, the workflow feature can only manipulate video files being uploaded. To perform media operations on cloud data, use the batch job triggering feature.

    Can CI split one video into multiple ones?

    CI allows you to split a video by setting the time ranges in the transcoding job or segmenting the video in the remuxing job.

    Do I need to set the serial number during video frame capturing?

    Use the ${number} variable during video frame capturing to indicate the increasing order of captured video frames.

    How do I get the media file information in CI?

    You can call the GetMediainfo API to get the media file information. Sample request:

    Is CI's media processing feature available to buckets in Hong Kong (China)?

    No. To process videos, use buckets in Beijing, Shanghai, or Guangzhou.

    Can CI's transcoding feature process source files?

    In CI workflows, you can use custom functions to batch process source files or workflow upstream files.

    What formats does CI's transcoding feature support?

    CI supports codecs of H.264, H.265, VP8, VP9, and XAVC as well as container formats of AVI, MP4, MKV, FLV, MOV, MXF, HLS, TS, MP3, AAC, and FLAC. For instructions, see Audio/Video Transcoding and Top Speed Codec Transcoding.

    How do I create a video watermark template in CI?

    CI allows you to create custom video watermark templates in the following steps:
    1. Log in to the CI console and click Bucket Management on the left sidebar to enter the bucket list.
    2. Click Manage in the Operation column on the right of the target bucket to enter the bucket management page.
    3. Select the Media Processing tab on the left and click Template at the top to enter the template configuration page.
    4. Click Video Watermark > Create Video Watermark Template to enter the video watermark creation window for custom configuration. The configuration information of the video watermark template is as follows: . For unified parameters, image watermark parameters, and text watermark parameters, see Template.
    5. Click OK.
    After successfully creating the template, you can preview, view, edit, or delete it in the custom template list. You can click Preview to view the position and dimensions of the watermark in videos of three common resolutions and quickly adjust the template.
    1. You can add up to three watermarks in the console or five via API at a time.
    2. You can apply the video watermark template when creating an audio/video transcoding job or workflow in CI.

    How do I perform comprehensive transcoding on existing data in CI?

    We recommend that you use the batch job API to process large amounts of existing data.
