The following also applies to the fork from 6by9.

$ uname -a
Linux sa1 4.19.19-v7+ #1198 SMP Tue Feb 5 14:53:32 GMT 2019 armv7l GNU/Linux

Using above kernel & f/w always produces this:

$ ./graph_decode_render
startmmal: mmal_port_enable: vc.ril.video_decode:ctr:0(0x1664070) already enabled
mmal: mmal_graph_enable: could not enable port vc.ril.video_decode:ctr:0
stop decoding

The supplied test file plays ok, but subsequent attempts often fail, & many valid .h264 files (I just substituted

SOURCE_OPEN(argv[1])

for the hard coded test file)

silently quit the application immediately.
