Hello all,
Here is some sample code to play any type of file supported by
gstreamer's playbin. I think it is a good substitute for
pyclutter/examples/videosink.py. Lots of code has been omitted that let
you connect gstreamer's bus to a callback so this is simple.
# Simple video player that outputs to a clutter texture
# For more funky control of the gst player like bus messages
# seeking and pausing, please see the gstreamer playbin document
# This has been tested with clutter trunk and not the stable branch
import gst
from clutter import cluttergst
import clutter
import gobject
import sys
class GstPlayer:
def __init__(self, stage, vfile):
self.stage = stage
self.video_texture = cluttergst.VideoTexture()
self.pipeline = gst.Pipeline("mypipe")
self.playbin = self.video_texture.get_playbin()
# Setup uri and sinks
self.set_location(vfile)
self.pipeline.add(self.playbin)
# Finally add the video to the stage
self.stage.add(self.video_texture)
# play it
self.pipeline.set_state(gst.STATE_PLAYING)
def set_location(self, location):
if not gst.uri_is_valid(location):
location = "file://" + location
self.playbin.set_property('uri', location)
def main():
stage = clutter.stage_get_default()
stage.set_size(320,240)
stage.set_color(clutter.color_parse('DarkSlateGrey'))
stage.connect('key-press-event', clutter.main_quit)
player = GstPlayer(stage, sys.argv[1])
stage.show_all()
loop = gobject.MainLoop()
try:
#loop.run() # This runs the gobject main loop via python
bindings
clutter.main() # This has the side effect of making telepathy
unusable
except KeyboardInterrupt:
print 'interrupted'
return 0
# the first command line argument is the name of the file or a URI
if __name__ == '__main__':
main()
