--h264 causes `gst_parse_error`

[ghillebrand]

Hi,
Running on a Pi4, HDMI->USB dongle input (from a Sony A7s)
OS updates run, Latest source cloned, running wired Ethernet both both sides.

The command
python3 publish.py --libcamera --buffer 10 --noaudio --framerate 25 --streamid GHTEST --h264

Generates a gst_parse_error

Error at line 1373 in /home/vdo/raspberry_ninja/publish.py: gst_parse_error: no property "bitrate" in element "v4l2h264enc" (2)
Called from line 1604 in /home/vdo/raspberry_ninja/publish.py

And no resulting stream. Tried rebooting, still get the error.

The full screendump from command to error is here.

Thank you for reporting. I'll get a fix out shortly. Might be some version incompatibly with gstreamer, but I normally try to handle these issues gracefully.

What version of Python is needed. The image ships with 3.9 - does that need to be updated?

@ghillebrand I pushed some changes -- I tried to add better error handling, but got a bit carried away and made other changes as well. Hopefully this fixes the issue you were facing -- if it doens't , or creates a new one, please poke me.
