--- Comment #13 from Jan ONDREJ (SAL) <ondrejj at salstar.sk> ---
Confirming reproduction with you gst-launch command.
Trying to experience with min-threshold-time directly on my udp stream:
gst-launch-1.0 udpsrc address=232.232.64.119 port=5004 ! queue
min-threshold-time=1 ! decodebin name=dec dec. ! queue ! pulsesink dec. ! queue
! xvimagesink
Here are results for different threshold times:
0 - jamming
1 - 500000 - playing well, it's enough to set it to 1
>5000000 - nothing happens, no video/audio opened, waited more than 10 seconds
Trying to set buffering (flag 0x100), buffer-duration, but doesn't help
(python):
self.playbin.set_property("flags",
0x001 # render video
| 0x002 # render audio
| 0x004 * int(bool(self.subtitle_files)) # render subtitles
| 0x008 # audio visualization
#| 0x010 # soft volume
| 0x080 # progressive download buffering
# buffering will break playing of large mkv files
| 0x100 # buffering
| 0x200 # deinterlace
#| 0x400 # soft-colorbalance
)
#self.playbin.set_property("buffer-size", 100*1048576) # 100 MB
self.playbin.set_property("buffer-duration", 10*nanosecond) # 10s
Because this worked well with gst-1.4.5, I think this should work with newer
versions too.
