Live Transcoder upgrade

Nimble Streamer Live Transcoder was released in early 2016 and since then it has got many useful features which our customers use widely. The core technology of the Transcoder combines both Softvelum team's own know-how and third-parties' work. Those third parties are listed on a corresponding page.

As we add new functionality, some core third-party technologies also advance forward. For instance, FFmpeg which is used for filtering and some decoding operations, has moved from version 3 to version 4, getting some important fixes and improvements. So in order to keep pace with FFmpeg, our team had to make adjustments and use latest version 4.

New FFmpeg version requires changes in both Nimble Streamer and Live Transcoder. So if you decide to make upgrade of Nimble Streamer then, in order to make smooth transition among versions, Nimble and Transcoder packages will have to be upgraded simultaneously. If one of the packages is upgraded without its counterpart, then live transcoding will stop working.

So here is what you need to do in order to complete this upgrade the correct way.

For Ubuntu, run this command
sudo apt-get update
sudo apt-get install nimble nimble-transcoder

For Debian, run this command
apt-get update
apt-get install nimble nimble-transcoder

For CentOS, run this command
sudo yum makecache
sudo yum install nimble nimble-transcoder

You may also run procedures from Live Transcoder upgrade page first and then Nimble Streamer upgrade page one after another do get the same result. If you have Windows, you also need to follow this path.

So we recommend you to perform this simultaneous upgrade when you have time and resource for that.


After the upgrade is complete, your Nimble Streamer package version will be 3.6.0-1 and Live Transcoder package version will be 1.1.0-1.
