How can I record video on a Pinephone?

[kk22]

I'd like to be able to take a short maybe 10 second video using the Pinephone's camera. There seem to have been a few individuals who figured out how to do this, but they used very different methods and none of them seem to be currently functional:

Reddit post by UJC_theguy, who was able to use ffmpeg to record a video. Trying his method (with /dev/video2 since that's what my camera shows up as), I get the following:

Code:

[video4linux2,v4l2 @ 0xffff9790b670] ioctl(VIDIOC_STREAMON): Broken pipe
/dev/video2: Broken pipe

Reddit post by Atticus83, who used gstreamer instead of ffmpeg. Trying his method the _jprocess script fails with

Code:

WARNING: erroneous pipeline: no element "x264enc"

Python script from Martijn Braam, which uses ffmpeg to do the recording. Modified to use /dev/video2, it gives the following:

Code:

  libavutil      56. 70.100 / 56. 70.100
  libavcodec     58.134.100 / 58.134.100
  libavformat    58. 76.100 / 58. 76.100
  libavdevice    58. 13.100 / 58. 13.100
  libavfilter     7.110.100 /  7.110.100
  libavresample   4.  0.  0 /  4.  0.  0
  libswscale      5.  9.100 /  5.  9.100
  libswresample   3.  9.100 /  3.  9.100
  libpostproc    55.  9.100 / 55.  9.100
[video4linux2,v4l2 @ 0xffffae633670] The driver changed the time per frame from 1/20 to 1/15
[video4linux2,v4l2 @ 0xffffae633670] ioctl(VIDIOC_STREAMON): Broken pipe
/dev/video2: Broken pipe

So how can I record video if these don't work?

Edit: Atticus83's method actually does work, but the "ugly" gstreamer plugins are needed. When I wrote this post I thought I had already installed them, but upon trying to install all of the gst-plugins-* packages in pmOS, gst-plugins-ugly got installed and now it works. If anyone knows of a better method though, please post it here.
