AW: How hard can it be to change filesrc location runtime

[Thornton, Keith]

Hi,
Probes are called from the streaming thread and in this thread you can't change the state of the pipeline. Can you not change the state to READY from a different thread, change the location and then change the state to PLAYING.

Betreff: How hard can it be to change filesrc location runtime

Hi,

I seems to overlook something when I change the element filesrc location at runtime.

I tried already to change the location already in different ways and dis read the documentation concerning dynamic pipelines

At this moment I simplified the pipeline to :  filesrc | decodebin| autovideosink, but still I seems to do something wrong.

What I already tried is :


  *   In blocking probe on file source  I changed location with/without filesrc state changes(GST_STATE_NULL and sync with parent )  and pipeline changes ( GST_STATE_READY and GST_STATE_PLAY)
  *   With 2 probes and send eos as explained  in dynamic pipeline documentation , and this with creating new filesrc and/or decodebin.
  *   With posting a message and  change file location when message received to avoid deadlocks

I  really have no idea what I'm doing wrong or if it is even possible.

I would appreciate if anyone can point me in the right direction or explains me the sequence of actions to take

Cheers ,
marc
