• How to convert cctv footage to h265 for streaming and recording in nginx-rtmp module ?

  6 avril 2021, par Joram

  I am using the nginx-rtmp-module here to pull an rtsp stream from a camera on local network and convert it to rtmp. This rtmp stream is then converted to hls and made available for livestreaming. It is also being recorded in 5 min segments. (these things can all be seen in the nginx.conf below).

  


  I want to change the video codec to h265 to save storage space, since each 5 min video is ~230mb, and using opencv and python, I was able to get <100mb per 5 min video using h265, so I know there is a lot of space for storage saving.

  


  How can I change the codec of the stream to h265 ?

  


  I have tried installing libx265-dev and setting -vcodec libx265, however this tells me flv is an invalid container and I'm getting nowhere with finding a valid container for streaming + recording.

  


  My nginx.conf :

  


  rtmp {
    server {
        listen 1935; # Listen on standard RTMP port

        application relay {
            
            live on;

            hls on;
            hls_path /tmp/hls;
            hls_fragment 15s;


            exec_static /usr/bin/ffmpeg -i rtsp://test:test@192.168.100.10:8554/fhd -vcodec copy -f flv rtmp://localhost:1935/relay/fhd; 

            # record block  
            record video;
            record_path /tmp/hls;
            record_unique on;
            record_interval 5m;
        }
    }
}


  


• node ffmpeg module stuck more than one file

  29 mai 2021, par Muhammad Hamza

  when I read more than one file it will be stuck and also hang my pc. I need to restart my pc

  


  on one file or 5 files it will work perfectly but not more than 5 files

  


  if anyone know this issue let me know

  


  const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path
const ffmpeg = require('fluent-ffmpeg')
ffmpeg.setFfmpegPath(ffmpegPath)


const testFolder = './videos/';
const fs = require('fs');

 


fs.readdir(testFolder, async(err, files) => {
  try {
    for(let i = 0; i < 10; i++){
      if(files[i] != '1 Surah Fatiha Dr Israr Ahmed Urdu - 81of81.mp4'){
        
        let converter = await ffmpeg(`./videos/${files[i]}`)
        await converter.setStartTime('00:00:00').setDuration('30').output(`./outputfolder/${files[i]}`).on('end', function(err) {
        if(err) { 
          console.log(`err durinng conversation \n ${err}`) 
        }
        else{
          console.log(`Done ${files[i]}`);
        }
        }).on('error', function(err){
          console.log(`error: ${files[i]}`, err)
        }).run()
      }
    }
  } catch (error) {
    console.log(error)
  }
});



  


• Shutil not detecting ffmpeg module and python3 incorrectly, all when compiled with pyinstaller

  9 juin 2021, par vanilla

  Right now I am almost finished with my version of my app. The last thing I am having trouble with is detecting the FFmpeg module, to warn users that they need it for certain features that have been added this version. When I run the script through my python interpreter in terminal, which the directories of it is in my library frameworks directory, The shutil will run as expected and return the version or whatever as I do have it installed. However, when I compile it and launch specifically the one windowed, with no console output, it doesn’t work. Now what I mean by that it returns none type.

  


  From talking to someone in my previous Reddit thread I tried printing out python3 and seeing what directories that would bring with shutil.which(‘python3’). Interesting enough, when put into my tkinter text field (don't have a console) it would bring up my python binary from the directory /usr/bin/python3. The one I have all my modules for it and everything installed on is the one :

  


  >>> import shutil
>>> print(shutil.which('python3'))
/Library/Frameworks/Python.framework/Versions/3.9/bin/python3


  


  So we can see that there are to installations or whatever of python3 interpreters (I believe I am saying this right), and I am confused on maybe I am being hinted to use the python3 binary from /usr/bin/ to compile it with pyinstaller and install the needed modules with /usr/bin/pip3 with it ?

  


  A user from the reddit thread I made below made a alternative :

  


  


  I tested it on my computer after fixing a bug, and both the shutil and os methods work. It seems to be a problem on your end, which is strange. What version of Python do you have ? Also in your script right above testing for ffmpeg, try inserting this line :
print('ffmpeg' in os.listdir('/usr/local/bin'))

  


  


  This other method with os unfortunately returned a None as well. I am ultimately trying to have some kind of method to reliably detect ffmpegs's binary on all operating systems. If anyone can provide some insight as to what may cause problems similar to these or knows other solutions, or can identify some kind of hiccup I can avoid that would be amazing.

  


  I have a hunch since shutil when compiled returned the bin directory for python3 instead of the framework one that actually has all the modules installed, that could mean something to me to try using pyinstaller with that one instead ?

  


  Thanks !
