• How to stream RPI a RPI Cam with ffmpeg for 24/7 to youtube stable and reliable

  6 mai 2021, par John Paden

  As a part of a project to bird-watch, I use RPICam
(https://github.com/silvanmelchior/RPi_Cam_Web_Interface)
on an Pi4. Resolution is 854x480, 25 fps. Works fine, stable 24/7.

  


  To share the videos not only in the intranet but on youtube, I use ffmpeg.
Other infrastructure : 1GBLAN, high speed extenal network connection, pi has stable power supply (no yellow flashes).

  


  After a lot of reading and testing, this command line produces a bitrate of about 2500 kbits and a speed of 1.

  


  ffmpeg -hide_banner -i http://xx.xx.xx.xx/cam_pic_new.php -deinterlace -re -acodec pcm_s16le -ac 2 -f s16le -i /dev/zero -f h264_omx -c:a aac -ar 48000 -ac 2 -b:a 384k -c:v h264_omx -b:v 2.5M -profile:v high -force_key_frames "expr:gte(t,n_forced/2)" -s 854x480 -pix_fmt yuv420p -strict experimental -use_editlist 0 -movflags +faststart -f flv rtmp ://a.rtmp.youtube.com/live2/xxx-xxx-xxx-xxx-xxx

  


  IF it starts correctly. As Youtube rules suggest to limit streams to under 24h to keep them, a regular reset of the tream - or the pi - is required.
On the youtube side this is controlled by
Often a restart (no matter of a "sudo restart" or just a restart of the ffmpeg command) results in youtube studio showing a green button (Stream status very good) and a second green button (Very good connection). But instead, the circle turns around ongoingly and it states 'Streaming Software can be connected now, viewers can find the stream once it has started'.
In short - how does youtube understand to start the transmission, or to reset if it still some sort of busy ?

  Hi, this is Tom from InnoCraft. The company of the makers of Piwik.

  No matter what type of website or app you have, whether you are trying to get your users to sign up for something or sell products, there is a certain number of steps your visitors have to go through. I bet the same applies to you.

  Have you ever wondered if your visitors or users actually follow that path in your website or app ? And wondered where you lose your visitors ? Where they maybe get confused ? Want to see when something is not working anymore ? Maybe you have a multi step signup form or onboarding process ? On every step you lose visitors and therefore potential revenue and conversions. It’s critical to know how well your visitors go through these steps, where they originally came from and where they go to when they drop off.

• Video streaming from server to client

  28 juillet 2016, par Johnnylin

  Currently, my program can use ffmpeg to encode yuv420p image into H264 video format and then output to network stream using udp protocol. Then on the client side, a GUI program using VLC library can read the network stream and display the video stream.

  HOWEVER, Using above method, I have to know every client side IP address and recompile the server code to send the network stream to client’s IP address using UDP. I want to implement something like, on the server side, the program will listen to a port (e.g. 1234), waiting for clients’ GUI program to connect, then on the client side, people can login to the GUI program in different computers with different IP addresses to connect to the server asking for network stream.

  What else should I do with my current program ? How can I do that ? Can someone show me a minimum example ?

  EDIT

  I have set up a ffserver, and used my program to send stream data to this ip address :

  http://localhost:8090/feed.ffm

  But I got this error :

  

  My configuration is pretty simple.

  

  I do understand why this happened. The server side show no error at all. Can anyone explain ? I tried to find solutions to this, but nothing succeeded.
