如何在Azure媒体服务上流式传输上传的视频

Question

I uploaded a video to Azure Media Services, and clicked the "publish" button. That gave me a publish URL.

I then used the Azure Media Player ( http://amp.azure.net/libs/amp/latest/docs/samples.html ) to embed my video content on a page.

The problem I'm having is that the video is choppy to start. Perhaps it's the encoding of the video, but I want to make sure, if I want to stream a video, using the media player or anything else, do I just use the "Publish URL"? OR is there a different way of requesting video content to "smooth stream"?

Answer 1

I have a series of tutorials on how to do this. Start here, Using blob storage with Media Services

Like you mention above, it will give you two different assets:

1. The blob storage asset
2. The Media Services asset

I prefer to start uploading my content to blob storage first, so that I can place them into folders and keep them organized . Then, I hop into Media Services, and have the services point to the file in blob storage. Much easier to keep things tidy.

Moreover, you can now stream either the file in blob as a .mp4, or use media services to encode it to a variety of formats, such as adaptive bitrate, which will return a manifest file.

Finally, be sure to start your streaming channel from within the media services portal and keep that on! You do not need it for a simple .MP4, but for adaptive bitrate you will need it.

Answer 2

Yes. You use the publish URL for VOD and you have a few url parameters to change the type of streaming if needed. Default is smooth streaming.

Smooth Streaming

{streaming endpoint name-media services account name}.streaming.mediaservices.windows.net/{locator ID}/{filename}.ism/Manifest

HLS Streaming

{streaming endpoint name-media services account name}.streaming.mediaservices.windows.net/{locator ID}/{filename}.ism/Manifest(format=m3u8-aapl)

MPEG Dash Streaming

{streaming endpoint name-media services account name}.streaming.mediaservices.windows.net/{locator ID}/{filename}.ism/Manifest(format=mpd-time-csf)
