Successfully compiled gStreamer 1.4 for RPI2

Sinamics

I have successfully compiled gStreamer 1.4 on RPI2.
Copy the attached gstreamer.sh file to RPI2

chmod 755 gstreamer.sh
./gstreamer.sh

This will take approximately 4- 6hrs. So do it over night. 🙂

After compiled, we need to make some last changes to this file,

nano .profile

Add these lines to the bottom.

export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-1.0/
export GST_OMX_CONFIG_DIR=/usr/local/etc/xdg/
export LD_LIBRARY_PATH=/usr/local/lib/

Then reboot and type:

gst-inspect-1.0 | grep omx

You will see all the hardware encoders available.

Thank you for some great tutorials!.

I can start to tell you that im a complete noob in linux/rpi..

I have unsuccessfully tried to install gstreamer and get it to run on my rpi2.

with Err 404 not found on:
libavformat53
libavfilter2 armhf
main ffmpeg armhf
failed to fetch:
libavformat5
libavfilter2
ffmpeg_0.8.1

when i try to launch gstreamer.sh i get "not found" on almost all of the syntax.

Is ffmpeg not available anymore or is it the rpi2 that dont recognize it?

What is the best option for me:

buy another rpi that works with your tutorial?
try to compile gstreamer 1.4 for rpi2?

best regards

Niklas

Hi and welcome nilund.

Im currently testing gstreamer1.4, just to see if i can get better perfomance.
You can install gstreamer1.0 with the following syntax.
sudo apt-get install gstreamer1.0

Then try to use this pipeline(You need to define your destination ip.) and revert with the outcome.

gst-launch-1.0 -v -e v4l2src device=/dev/video0 ! video/x-h264,width=640,height=480,framerate=30/1 !
tee name=t ! queue ! rtph264pay pt=96 config-interval=1 ! udpsink host= port=5000

I belive you tried gStreamer.sh from my blog? correct?
Did you alter something in that file?
gstreamer is quite sensitive to pipeline elements, and one wrong character will or can destroy the streaming.

I can test this file tonight, just to verify.

nilund

when i try to install gstreamer it "failed to fetch" some of the libraries, see the attachment. is this because of the rpi2?

I edited the gstreamer.sh with my local ip from my laptop.
and when i launch gstreamer.sh it says not found on almost everything, see the attachment.

Sinamics

have you executed apt-get update?

nilund

all codecs seem to be in place after the apt-get update. thank you!
but it still says exactly the same thing when i try to execute gstreamer.sh

i have put the gstreamer.sh in the attachment and a screendump of the result.

try this pipeline. Remeber to change the $ip

gst-launch-1.0 -v rtpbin name=rtpbin v4l2src device=/dev/video0 ! video/x-raw,width=1280,height=720,framerate=30/1 
! queue ! omxh264enc target-bitrate=900000 control-rate=1 ! queue max-size-bytes=10000000 
! "video/x-h264,profile=high" ! rtph264pay pt=96 config-interval=10 ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 
! udpsink port=5000 host=$ip ts-offset=0 name=vrtpsink rtpbin.send_rtcp_src_0 
! udpsink port=5001 host=$ip sync=false async=false name=vrtcpsink udpsrc port=5005 name=vrtpsrc 
! rtpbin.recv_rtcp_sink_0

nilund

cant get it to work. different error.

is the $ip for the ground control? screendump

nilund

and here is the gstreamer.sh

Sinamics

Hi Could you open port 22 to your RPI and PM me your external ip.
I can connect and have a look.

Sinamics

now its running. 🙂

Sinamics

Reason why it did`t work was simply becouse of trailing trash when copying code from this thread.
To avoid unwanted html tags , you should copy line by line and paste it in file using Vi or NANO editor directly in RPI.
I will fix this copy problem very soon.

nilund

Thank you very much for the help! I will Continue tomorrow with the other configs.

Rybat

Is it possible to condense the posts here for a single instruction set?
It is a bit difficult to follow.
Thanks

Sinamics

Hi Rybat

Do as described in first post.
If you get any errors when running gstreamer.sh you should create a file on RPI e.g ( nano gstreamer.sh )
Copy paste the code bellow and save the file.

Set permission to the file

chmod 755 gstreamer.sh

Run the script file you just created

./gstreamer.sh

gstreamer.sh

#!/bin/bash
 
# Create a log file of the build as well as displaying the build on the tty as it runs
exec > >(tee build_gstreamer.log)
exec 2>&1

Perfect!
Thanks

Sinamics

no problem.. keep in mind that it will take some hrs to compile.. 🙂

Rybat

I did your gstreamer1.4 compile and was able to see the codecs list

but, I was never able to get a stream I then started from scratch with the emlid RT and then followed their instructions for gstreamer1.0

again no stream due to mmal errors

Note: I am using a Logitech C920. The C920 is a nice camera and under linux is supported by V4L2 and UVC. Under V4L2 it provides 30fps at 1080p (amongst other combinations) with applications that supports H.264 directly, and can pull in the H.264 stream directly from the camera. The C920 does on-board H.264 compression at fixed 5Mb/s, but most applications don’t support pulling the compressed stream straight from the camera; instead, they have to decompress then re-compress the stream, dropping the frame rate. Under UVC (i.e: YUV/YUY mode) support for C920 is there, but it’s not very good for higher resolutions (i.e: 1080p). I have RPi v2b+

Thanks

Thanks for V4L2 and UVC info. I did not know the difference between those two, but i do now.. thx.

According to you picture gst-launch-1.0 is not found. Please verify that you have gst-launch-1.0 available, if not reinstall gstreamer.
mmal errors is often set if camera is not configured in raspi-config. Please verify your raspi-config settings.
mmal errors will also occur if 2 processes try to access the camera module simultaneously.

It seems to me that, C920 already provides h264 compression. I think it would not require gstreamer to transcode and the re-compress. This is a waste of resources. Is there a method to simply stream the camera's output without the extra processing?
maybe ffmpeg like this: http://derekmolloy.ie/streaming-video-using-rtp-on-the-beaglebone-black/

Thanks for your assistance

Streaming Video using RTP on the Beaglebone Black

Introduction
In a previous post, I described how you could set up the Beaglebone Black to capture video and process video using OpenCV with the Logitech C920 camera. In this post I am going to look at how you can begin streaming data using the camera and code that I had adapted previously.
