Splicing allows the combination of various video and audio clips to generate a unique output. The process can be employed simultaneously with other media processing operations.

How to Use

Structure your fops in the request body as follows:

<op>/<Format>
    /mode/<value>
    /concatorder/<value>
    /moovToFront/<value>
    /<encodeUrl1>/<encodeUrl2>...
    |saveas/<Urlsafe_Base64_Encode(bucket:filekey)>

Video/Audio Splicing Parameters

Parameter	Required	Description
op	Yes	Operation type. For media video/audio processing, set the operation type to `avthumb`.
format	Yes	Target format for output, such as mp3, mp4, m3u8, etc.
mode	No	This signifies the type of merging operation being performed and can have a value of either `1` or `2`: 1: This is employed when the codecs in the files being merged are identical. You should set the mode to 1 when splicing audio files. 2: This is used when the codecs differ between the files being merged.
concatorder	No	This designates the sequence in which files are spliced, denoted with a hyphen in between. For instance, `2-1-4-3` signifies the order in which four files should be concatenated.
moovToFront	No	The `moov` atom in MP4 files contains essential metadata. This parameter specifies whether to place the moov atom at the beginning for improved playback performance, especially for streaming. 0 (default): Keep metadata at the end (as usual). 1: Move metadata to the beginning for faster startup.
<encodeUrl1>/<encodeUrl2>…	Yes	To designate the files for concatenation. The name of each file to be concatenated should be encoded in URL-safe Base64, with each encoded file name separated by a `/`. For example: `Urlsafe_Base64_Encode (test_1.mp4)/Urlsafe_Base64_Encode (test_2.mp4)` Please note that all files should come from the same bucket on Object Storage. Also, the system supports the concatenation of up to 5 files at a time.
saveas	No	This parameter defines the output location and filename as a `URL-safe Base64-encoded string` with the pseudocode `Urlsafe_Base64_Encode(bucket:savedfilename)`.

Request Example

This example showcases the process of merging two videos, specifically named test_1.mp4 and test_2.mp4, located in the selected bucket vod-wcs-test001. The final output is a single video named test_merge.mp4.
Pseudocode format for the request:

curl -v -X POST 
–d "bucket=Urlsafe_Base64_Encode(vod-wcs-test001)&key=Urlsafe_Base64_Encode(test_1.mp4)&fops=Urlsafe_Base64_Encode(avconcat/mp4/mode/1/Urlsafe_Base64_Encode (test_1.mp4)/Urlsafe_Base64_Encode (test_2.mp4)|saveas/Urlsafe_Base64_Encode (vod-wcs-test001:test_merge.mp4))&force=1&separate=1" 
–H "Authorization:AccessKey:EncodeSign" 
--url "http://mgrDomain/fops""

Actual request format:

-curl -v -X POST 
-d "bucket=dm9kLXdjcy10ZXN0MDAx&key=dGVzdF8xLm1wNA==&fops=YXZjb25jYXQvbXA0L21vZGUvMS9kR1Z6ZEY4eUxtMXdOQT09fHNhdmVhcy9kbTlrTFhkamN5MTBaWE4wTURBeE9uUmxjM1JmYldWeVoyVXViWEEw&force=1&separate=1"
