Ubuntu to livestream with the "THETA Z1 51G"

[yukki-tanaka]

Hello

I'm now trying to get Ubuntu to livestream with the "THETA Z1 51G"

But, both "gst / gst_viewer" and "gst / gst_loopback" become "Error: Internal data stream error."

What causes this ERR and how can it be resolved?

My environment is as follows.

---

$ lsmod

~~
v4l2loopback 45056 0
~~

---

$ glxinfo -B
~~
Extended renderer info (GLX_MESA_query_renderer):
Vendor: Intel (0x8086)
~~

---

$ lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04
Codename: focal

---

$ ls
Makefile gst_viewer gst_viewer.o thetauvc.h v4l2loopback
gst_loopback gst_viewer.c thetauvc.c thetauvc.o

---

$ ./gst_loopback
start, hit any key to stop
Error: Internal data stream error.
stop

Postscript

When I set "export GST_DEBUG =" *: 2 "and executed it, there was no" h264parse ", so I installed it and executed it again, the following ERR appeared.

I recently recorded the process of downloading and compiling On Ubuntu 21.04 x86.

This is in addition to the previous video walkthrough with 20.04 (slightly older repo)

This is the build on Jetson Nano

There is a forum here:
https://community.theta360.guide/t/live-streaming-over-usb-on-ubuntu-and-linux-nvidia-jetson/4359?u=craig

This will install all gstreamer plug-ins on 20.04

$ sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio libgstreamer-plugins-base1.0-dev

I am using firmware 1.80.1 on Z1.

Thank you for your answer.

When I installed the plugin, it worked fine.

I will close it.

Thank you very much.
