how to force GstBaseParse to lost sync

[Julien Isorce]

Hi,

I would like to force ac3parse to resync (see gst_ac3_parse_check_valid_frame, sync word) somewhere in the stream.

I looked into GstBaseParse code and it seems to depend on "parse->priv->discont".

 

And it seems there are 2 ways:

* call gst_element_set_state(ac3parse, GST_ELEMENT_READY) to call "gst_base_parse_reset" to set discont to TRUE. (then back to PLAYING)

* push a GST_EVENT_FLUSH_STOP on the source pad connected to the sink pad of ac3parse.

But those 2 solutions are also reseting every stuffs in ac3parse whereas I just would like to resync. (I would like to make GST_BASE_PARSE_FLAG_LOST_SYNC return TRUE).

Is it already possible ? Or it needs some dev ?

Sincerely

Julien

:)  well it seems I am trying to by pass a bug or a mal formated ac3 buffer. I do not know who is wrong yet.

I am going to open a bug to follow that.
