Azure video streaming: Custom encode format using REST API? - azure

Question

i'm using below REST call to encode the video uploaded,
POST https://wamsbayclus001rest-hs.cloudapp.net/api/Jobs HTTP/1.1
DataServiceVersion: 1.0;NetFx
MaxDataServiceVersion: 3.0;NetFx
Content-Type: application/json
Accept: application/json;odata=verbose
Accept-Charset: UTF-8
Authorization: Bearer http%3a%2f%2fschemas.xmlsoap.org%2fws%2f2005%2f05%2fidentity%2fclaims%2fnameidentifier=amstestaccount001&urn%3aSubscriptionId=z7f09258-2233-4ca2-b1ae-193798e2c9d8&http%3a%2f%2fschemas.microsoft.com%2faccesscontrolservice%2f2010%2f07%2fclaims%2fidentityprovider=https%3a%2f%2fwamsprodglobal001acs.accesscontrol.windows.net%2f&Audience=urn%3aWindowsAzureMediaServices&ExpiresOn=1421675491&Issuer=https%3a%2f%2fwamsprodglobal001acs.accesscontrol.windows.net%2f&HMACSHA256=9hUudHYnATpi5hN3cvTfgw%2bL4N3tL0fdsRnQnm6ZYIU%3d

"Name":"NewTestJob",
"InputMediaAssets":[
{
"__metadata":{
"uri":"https://wamsbayclus001rest-hs.net/api/Assets('nb%3Acid%3AUUID%3A9bc8ff20-24fb-4fdb-9d7c-b04c7ee573a1')"
}
}
],
"Tasks":[
{
"Configuration":"H264 Adaptive Bitrate MP4 Set 720p",
"MediaProcessorId":"nb:mpid:UUID:1b1da727-93ae-4e46-a8a1-268828765609",
"TaskBody":"<?xml version=\"1.0\" encoding=\"utf-8\"?><taskBody><inputAsset>JobInputAsset(0)</inputAsset>
<outputAsset>JobOutputAsset(0)</outputAsset></taskBody>"
}
]
}
But the built in encode formats of H264 Adaptive Bitrate are - H264 Adaptive Bitrate MP4 Set 720p,H264 Adaptive Bitrate MP4 Set 1080p,H264 Adaptive Bitrate MP4 SD 16*9,H264 Adaptive Bitrate MP4 Set SD 4*3 , these 4 formats encode the uploaded video into various output format, which results in larger encode data and takes more time to complete single encoding task. So i'm trying to encode the uploaded video file to only lower resolution formats, to reduce cost and time. Is there a way to implement it ?

Ok, so this is a little hackish, but hopefully it will give you an idea of what sort of configuration you'll need to provide to your job.
I fired up Azure Media Services Explorer and created an encoding job while running fiddler and using one of the encoding preset xml file provided. This is the body of the POST:

The "configuration" section contains the XML from the preset you can find here on GitHub. Hope this will lead you to the exact configuration you need to provide in the POST to create your job.
