python: Too many open files

[Patrick Shirkey]

Thanks Mattieu.

That was the hint I needed. Seems that the lplayer method with Gst instead of GstPlayer is leaking the stream file descriptor. In case anyone has the inclination to look into it further, I noticed it increments by three at play() and decrements by two at stop().
