Python Gstreamer plugin not working - no video output
System: Ubuntu 14.04 osboxes.org image with 3.13.0-112-generic kernel
No video output even with explicit -m gst option selected. IIRC video output played smoothly a few months earlier on a similar machine.
Command: sudo python play.py -a max -m gst -u http://yt-dash-mse-test.commondatastorage.googleapis.com/media/car-20120827-manifest.mpd
Output: 2017-03-24 11:43:26+0500 [-] Log opened. 2017-03-24 11:43:26+0500 [-] http://yt-dash-mse-test.commondatastorage.googleapis.com/media/car-20120827-manifest.mpd ^C2017-03-24 11:45:05+0500 [-] Received SIGINT, shutting down. 2017-03-24 11:45:05+0500 [-] Main loop terminated.
Fake option also returns verbose errors related to python and twisted.
What Python version are you using? Can you please attach the error messages that are returned when running with the fake media renderer? You should make sure to resolve any Python related issues first before trying to debug the GStreamer stuff.
Hi @shamidrasool , as @pckbls correctly mentions, probably you are missing some python dependencies. Can you confirm you have installed all the required packages? Try to run: GST_DEBUG=2 DEBUG=2 python play.py -a max -m fake -u http://yt-dash-mse-test.commondatastorage.googleapis.com/media/car-20120827-manifest.mpd
and check if some gstreamer plugin is missing.
osboxes@osboxes:~$ python -V Python 2.7.6

It goes without saying that any DASH ABR algorithm prototyping experiments can be carried out on the 'nodec' mode yielding acceptable results but the great thing I liked about your framework was the video player capability which can be useful in demos and presentations. :)
I also tested on Ubuntu 15.04 VBox with 3.19.0-82-generic kernel with all dependencies installed.
Still no video in gst mode. Here is the fake media engine error:
