Love the idea of gstreamer; HATE the execution

The last rant-like comment that surfaced was "It seems to me that the whole
gst is very nice but fraught with gotchas if you venture off the trodden
path".   I don't believe the problem is with Gstreamer or the community.
I'm confident the problem is with the current times we are all living in.
We're told to be agile and go fast and faster which leaves us no time to
explore and enjoy. The endless slave drive. I sense Dave is being pressed
for time hence his frustration. I've been there many times and I'm there
right now with v4l2 hardware decoding for Raspberry PI - almost a week of
work and no solution (shell compiling my solution as I type this).

My advice is, if you can, only do software development as a hobby because
it's not easy despite the 75 years of history. I would not recommend
software development for work or to earn a living because eventually you'll
run into frustration driven by slave drive.

Hope you all have a very Merry Christmas and a Happy New Year.
