I'm a little bit further in the comprehension but this need help !
The problem seems to be that a segment event is not sent.
If I put a "gst_base_src_new_seamless_segment" in the _create function,
thinks are better, it is not realtime and it crash regularly but at
least, it gives refresh in autovideosink.
Compared to videotestsrc, it lacks :
/GstPipeline:pipeline0/GstFakeSink:fakesink0: last-message = "event
******* (fakesink0:sink) E (type: 102, GstEventNewsegment,
update=(boolean)false, rate=(double)1, applied-rate=(double)1,
format=(GstFormat)GST_FORMAT_TIME, start=(gint64)0, stop=(gint64)-1,
position=(gint64)0;) 0x80608c0"
between the PLAYING and the clock setting but I don't know where to look
for.
If someone have a hint, it will be highly appreciated !
Thanks,
Jonathan
