Which events occur? In which order? Behaviour over a tee?

[Maurer, Marie]

Hello,

 

when debugging my own program I came to the point where I saw e.g. a STREAM_START event, followed by a CAPS event.

Is there a description what events occur and especially in which order they are sent? I am not sure if at least the start is independent from the pipeline used,

or I must even distinguish between a live video pipeline and a video playback pipeline.

 

Events are duplicated in a tee in the same way as frame data?

 

Is there perhaps a GST_DEBUG setting, where I can trace all of these events so I can clearly see what is used and in which order?

 

Many thanks!

 

Best regards,

 

Marie
