The Fix feature can be used to normalize the timeline and/or replace broken frames in the stream:

  • Make timeline continuous - if there are timeline jumps in the source, this feature will normalize the timeline, making it continuous. For example, this feature can be useful if the source is an HLS stream that jumps to display ads. In this case, if you want the timeline to be continuous it is possible to achieve this by enabling this feature. Note that this feature creates a variant of the input, which means that it doubles your input.

  • Broken frames replacement - If the stream has frames with CC errors, the broken frames replacement feature replaces them with “skip” frames. This may solve issues such as an IRD that loses synchronization when receiving broken frames. Note that this feature creates a variant of the input, which means that it doubles your input.

To fix the Input Stream:

  1. In the Inputs page, click the desired input stream that you want to fix.

  2. Click the Actions button on the selected row and then choose Fix.
