With Transcoding

Тhe Оriginal Stream Does Not Have The Desired Resolution and Transcoding is Required

The Base Stream Transcoding is necessary if you want to create a multi-bitrate stream or to change the transcoding parameters of the original stream. 

To add transcoded streams, follow the steps outlined below: 

1. Log in to the Universal CDN Control Panel at my.ucdn.com.

2. Navigate to the Livestraming tab located at the top left corner:


3. In case a Live Streaming Zone is not yet created, click on the ‘New Live stream’ button:

3.1 In case a Live Streaming zone is already created, click on the cogwheel icon next to the Live Streaming zone (skip to point 5).

4.  Create a new RTMP Live streaming zone:

4.1 Stream name: Enter a friendly name for your Live Stream zone.

4.2 Include Base Stream in master.m3u8 – when transcoded streams are added, this option should be disabled. Otherwise, the option may lead to strange behavior in the player, when it is switching between transcoded and Base streams, as the duration of the .ts segments of the Base and the transcoded streams may differ.

5. Locate the ‘Base Stream Transcodings‘ section and click on the ‘Add‘ button:

6. From the pop-up window, you can adjust the parameters of the new transcoding slot of the base stream:

Resolution: You can choose between 360p, 480p, 720p, 1080p or 2160p resolutions.  

Video Codec: Choose H.264.

Frame Rate: (FPS). You can choose between 30 or 60 FPS.

Profile: You can choose between baseline, main or high profile. More additional information you can find here!

Audio codec: Choose AAC.

Once configured, press ‘Done‘.

8. Click on the Add Live Stream Zone button (if a new zone is being created), or the ‘Save Changes‘ button (if a Live Stream Zone was already created)

9. Once transcodings are created, they will be displayed in a list format:

9.1 You can activate/deactivate a transcoding, by checking/unchecking the ‘Active’ option.

9.2 Keep copy as MP4: If selected, the CDN system will keep a copy of a transcoded stream in MP4 format segments on your UCDN Storage.

9.3 To delete a transcoding, make sure that no transcoded streams are running, then select the bin icon next to the ‘Active’ button.

Any changes in the settings of your running stream will cause a restart of the stream session.
Deactivation of all of the transcodings will lead to the deactivation of the corresponding restreams.

10. The Publish URL and Publish Key can be viewed on the Main settings page.

Publish URL and Publish Key can be obtained on the Instruction page along with the URLs for your base and transcoded streams. Click on the ‘View’ button located next to your base or next to your transcoded streams to get their URLs.
