• Is there a way to convert uploaded videos to browser MP4 using most basic ffmpeg ?

  22 janvier 2016, par PeterTheLobster

  I am trying to convert videos uploaded to my website to browser friendly mp4 using ffmpeg.

  The Problem : the website is hosted by a company and it seems like it does not have the codecs I need (the ones I’m aware to be browser-friendly.) I have learned that h264 and libx264 are the codecs I would want to encode the mp4 videos to, but libx264 is not present and h264 is decodable only. Doing :

  exec("ffmpeg -codecs", $output);

  tells me that :

  D V D h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10

  I have tried converting the videos using mpeg4 codecs, but those are not supported natively in browsers it appears :

  $command ="$ffmpeg -i $target -b 1500k -vcodec mpeg4 -pix_fmt yuv420p -acodec aac -strict experimental $converted2 2>&1";
  
  exec($command, $output);

  The videos converted using the method above play only audio in chrome for example (the mpeg4 codec encoding is supported).

  Edit : I was able to convert videos to ogg and webm, but those won’t cover all browsers as far as I’m aware. Especially not the mobile ones anyway.

  Question : is there another type of basic ffmpeg, browser friendly mp4 codecs that I am not ware of or was there something wrong with my conversion $command above ? Or would I have to somehow try to install libx264 codecs and libraries ? (My guess is, that I probably cant do that to their servers, right ?)

• How to run ffmpeg on demand when someone opens my website with the player where a remote IP camera is displayed ?

  8 mai 2023, par alexiter

  I set up an nginx server to stream from an IP camera located elsewhere, I used a windows server because it was the one I had no use for (I usually prefer linux), I would need to know how I can make the ffmpeg command run only when someone opens the website where the player is located.

  


  This is my nginx.conf server code :

  


  worker_processes  1;

error_log  logs/error.log info;

events {
    worker_connections  1024;
}
rtmp {
    server {
        listen 1935;
        ping 30s;
        notify_method get;
        application live {
            live on;
            on_publish http://*******:8080/auth;
            dash on; 
            dash_path tmp/dash;
            
            
        }
    }
}
http{

   server {
        listen 8080;
        location /auth {
        if ($arg_psk = '*****') {
    return 201;
    }
  return 404;
  }
}
   
   server {
        listen 8443 ssl;
        server_name stream.*****.com;
        
        ssl on;
        ssl_certificate C:/Certbot/live/stream.*****.com/fullchain.pem;
        ssl_certificate_key C:/Certbot/live/stream.****.com/privkey.pem;
        ssl_session_timeout 5m;
        charset utf-8;
        location /dash {
            root tmp;
            add_header Cache-Control no-cache;
        }
        location / {
            root www;
        }
        

   }
}



  


  The command that I use from the DOS console in windows is this :

  


  ffmpeg -rtsp_transport tcp -i rtsp://*****:******@******.com:557/Streaming/Channels/101 -c copy -f flv -y -t 35 rtmp://********:1935/live/stream?psk=********


  


  Basically what I need is that ffmpeg is not running constantly, only when someone wants to view the video from the IP camera. (I have programmed ffmpeg to finish after 35 seconds, although I will put five minutes later)

  


• downloaded a streaming video file from a website with ffmpeg in 1080p but i wanted to download in 720p as i have disk space limitations [on hold]

  22 octobre 2018, par C.J.

  I apologize if my language was unclear let me try to rephrase the question. I have downloaded a video from a video streaming website called "hotstar.com" with the help of ffmpeg. I extracted the m3u8 link from the site and was able to download it. The video is in 1080p video resolution which takes a lot of space. I want to download it in 720p resolution so that it would take less space. the code that i tried for it was this

  ffmpeg -i "https://hsprepack.akamaized.net/videos/hotstarint/world/kwks6/1_2/master.m3u8?hdnea=st=1540184067~exp=1540185867~acl=/*~hmac=a8945f016b594e1e2e4192ee05e2feaa5811c687d1891f69be1acc9057dd725f"
  
  -c copy output.mp4

  I hope I have asked properly this time. If not do tell me what is more needed.
