Current Balena Pi0 image doesn't support gstreamer head #20

Open ajlennon opened 5 years ago

ajlennon commented 5 years ago

There's an issue with the RPi firmware used in the current Balena base image which causes GStreamer to fail to initialise the h264enc plugin

gst-launch-1.0 -v videotestsrc ! omxh264enc ! fakesink

gives

/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0.GstPad:src: caps = video/x-raw, width=(int)320, height=(int)240, framerate=(fraction)30/1, format=(string)I420, multiview-mode=(string)mono, pixel-aspect-ratio=(fraction)1/1, interlace-mode=(string)progressive

This is noted as a bug here and should be fixable with an rpi-update to the base image
