"Any thoughts on whether openshot-render is needed anymore? MLT already
contains a powerful command line tool called 'melt', which can render
openshot XML files, and those XML files can be exported from OpenShot.
Anyone disagree with me? =)"

Yes, openshot-render is needed.  See my comments 19 and 21 in Bug
#729359.

For those of us with lots of small projects, it would be extremely
useful to be able to do something like (shell script pseudocode
follows):

for P in *.osp:
  if file $P.webm does not exist (or is older than $P):
    openshot-render --outputfile=$P.webm ... $P

But this is impossible when openshot-render does not terminate properly!

Title:
  openshot-render never end

Status in OpenShot Video Editor:
  New

Bug description:
  command line renderer never exit, it creates output file without any problem but after call sys.exit() it hangs forever. Only way to stop it is to send a signal kill -1.
  Some work around is to use return instead of sys.exit() where possible eg in function main in openshot_render.py
  and in main program use os._exit(0) to force exit the script, instead throwing exception SystemExit with sys.exit().

  Used OS: Linux Mint 9 based on Ubuntu 10.04, OpenShot 1.1.3
