Inserting InsertSilenceIfNoAudio and InsertBlackIfNoVideo using custom presets
Azure Media Service preset (XML or Json) can't take InsertSilenceIfNoAudio and InsertBlackIfNoVideo same time.
We need this in cases like, if clip has no audio then encoder can use InsertSilenceIfNoAudio and if clip has no video then encoder can use InsertBlackIfNoVideo.
When I was going through this blog post https://docs.microsoft.com/en-us/azure/media-services/previous/media-services-advanced-encoding-with-mes#no_video I realized this feature is not available, also posted it here asking for details https://github.com/MicrosoftDocs/azure-docs/issues/20149.
Please either build this or confirm alternate option to achieve same.
