• Restream with FFmpeg [closed]

  30 mars, par boyuna1720

  I have iptv playlist file with inside VODs and Channel links. I want to restream it from my server becouse provider allows only one user to watch. When i am using Nginx with RTMP and FFmpeG i am getting this error. please tell me if anyone can help to fix this issue.

  


  ffmpeg -re -i "http://excel90095.cdn-akm.me:80/23a9a158d8d8/2dd736a985/325973" -c:v copy -c:a aac -f flv "rtmp ://localhost/live/test"

  


  

  


• FFMPEG pushed RTMP stream not working on Android & iPhone

  1er décembre 2015, par BlackDivine

  I have to make a semi-live-stream. I used Nginx-rtmp module and then pushed content to it via ffmpeg using :

  ffmpeg -re -i content.mp4 -r 25 -f fvl "rtmp://rtmp.server.here"

  The stream runs fine when I open it in VLC from "rtmp ://rtmp.server.here"

  But I also have to make iPhone and Android apps that play these streams. And that’s the problem, the stream doesn’t work on Android and iPhone.

  If I use Wowza streaming cloud and stream to Wowza cloud instead of my own nginx-rtmp server then the same app written for Android & iPhone can playback the stream just fine.

  Now either nginx-rtmp is not working right, or what else ? I’ve also tried crtmpserver and the same thing happens.

  What I want to acheive :
  I have to develop a system where we can upstream a TV-Channel (have rights for it) to a server and then make a website, android app & iPhone app so consumers can watch the live channel.

  The uploading part I have a clue of, probably a TV tuner card and Open Broadcast Software to stream it to server. But the Live playback is new to me.

  UPDATE : I also used ffprobe and here’s the output. (See the last line)

  Update 2 :
  I got my stream working by using Licensed copy of Wowza streaming server. Everything works now. But obviously this will not be an option for everyone that’s why I am not posting it as an answer.

• Architecture of video-based service for mobile phones

  27 juin 2015, par David Azar

  I guess this is more of a conceptual question than a technical one.

  I’m trying to figure out the best way to upload short videos to a server and also be able to download them and watch them on both Android and iOS.

  Lets focus on Android for the moment.

  I’ve done some experiments, and my results have been :

  • I’m able to compress 12-14MB video down to 500KB using FFMPEG lib with pretty good results in quality, but it takes about 12 seconds.

  • Next, im uploading those videos to my Parse backend as ParseFile to store them.

  • Finally, i can download them and watch them with no problem using a VideoView widget.

  Now, for the tests i’ve been running, these are great results. But i want to see if there is a better way to manage and scale all of this.

  My questions are :

  • Is there a better, lighter way to compress video ?

  • Is Parse the right way to go ?

  • How can i stream videos instead of downloading them and storing the on local storage before playing them ? i know this will cause my app to use significant space on disk and i dont want that.

  • How do big companies do this kind of tasks ?

  I’ve heard Amazon S3 is a cool thing for projects like this one, also Google Cloud Platform. I want to understand the best approach before building everything so i can do it the right way and also, provide the absolute best user experience for watching these videos.
