需求场景：我想对mp4文件做hls切片。
{

"Description": "demo_hls",
"PresetType": "avtrans",
"Param":{
"f":"hls",
"segment_time":6,
"segfile_acl":"public-read",
"AUDIO": {
"acodec": "copy"
},
"VIDEO": {
"vcodec": "copy"
}
}
}
需求场景：我只想在源视频上加水印，但不打算改变源视频的分辨率、码率等参数。

"Param":{
"f":"mp4",
"LOGOS":[
[

}
}需求场景：我为了水印效果更好，不想水印被过度缩放，所以准备了不同尺寸的2个水印logo文件，想根据转出视频不同尺寸加相应的水印logo（只加一个）。

拼接任务，模板设为普通的avtrans类型，在创建任务的时候SrcInfo设置为数组即可。
