Secondary (alternative) source for VLC

[sharbatgula]

Hi,

Is there a way/syntax to set secondary source (usually a static picture) that is used when there is an interruption on the primary source (input)?
For instance if there is a problem with the primary udp source (no frames detected for a certain period) the secondary source will kick-in and provide informative picture/video that there is an interruption with the source. When the primary source is back the input will have to switch back to it.
This is particularly useful when transcoding and recording and it is important to preserve the duration of the recorded material, i.e. have continuous transport stream with no errors in its structure due to the interruptions.

First you'd have to detect that the stream is dead. VLC currently lacks any heuristic to determine that an UDP stream is dead.
