• 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.

• Unable to upload video from iPhone with paperclip-ffmpeg in Ruby on Rails

  13 mai 2015, par sank

  When I upload a video from an iPhone, I’m getting the following error :

  Command :: PATH=/usr/bin/:$PATH; file -b --mime '/tmp/6da355e988ec841811d8803dfd5cf44c20150513-8103-b4lkam.MOV'
  
  [paperclip] Content Type Spoof: Filename IMG_2637.MOV (["video/quicktime"]), content type discovered from file command: inode/x-empty. See documentation to allow this combination.
  
  (0.6ms)  ROLLBACK
  
  Completed 400 Bad Request in 58ms (Views: 0.9ms | ActiveRecord: 5.0ms)

  (This works perfectly when I upload the same video from desktop.)

  I used gems "paperclip", "~> 4.1" and "paperclip-ffmpeg".

  In my video model :

  validates_attachment_content_type :student_video, content_type: /\Avideo\/.*\Z/

  also tried out

  validates_attachment_content_type :student_video, :content_type => ['video/x-   
  
  #                                        msvideo', 'video/avi', 'video/quicktime', 'video/3gpp', 'video/x-ms-
  
  #                                        wmv', 'video/mp4', 'flv-application/octet-stream', 'video/x-
  
  #                                        flv', 'video/mpeg', 'video/mpeg4', 'video/x-la-asf', 'video/x-ms-asf']

  But I’m getting the same error.
