• Crossdevice encoding static file to stream in browser using FFMPEG (segmented h264 ?)

  20 mars 2014, par Vprnl

  I'm building a mediacenter application in NodeJS which is going pretty ok.
  (you can check it out on Github : https://github.com/jansmolders86/mediacenterjs )

  I'm using FFMPEG to transcode local (static) movies to a stream which I then send to the browser.

  At first I used h264 with Flash which worked in browsers, but I really need it to work on Android an iOS (so no Flash) and preferably working on a Raspberry Pi.

  But getting it to play on all devices is driving me absolutely insane !

  I have all these bits of the puzzle I've gathered from countless hours reading articles, tutorials and stack overflow posts, which led me to the conclusion that I need to produce the following :

  • Use video codec H264 to transcode to MP4
  • Move the moovatom '-movflags' to make a MP4 streamable
  • Segment the stream so Apple can play the stream as well.

  But getting nowhere with this. Every time I produce a series of FFMPEG settings that either don't work, or work on some devices rather than all.

  Some of my failed attempt where :

  My flash attempt -> Main problem (not running in IOS) :

      '-y','-ss 0','-b 800k','-vcodec libx264','-acodec mp3'\ 
  
      '-ab 128','-ar 44100','-bufsize 62000', '-maxrate 620k'\
  
      metaDuration,tDuration,'-f flv

  my HLS attempt -> Main problem (not running in browser) :

          '-r 15','-b:v 128k','-c:v libx264','-x264opts level=41'\
  
          '-threads 4','-s 640x480','-map 0:v','-map 0:a:0','-c:a mp3'\
  
          '-b:a 160000','-ac 2','-f hls','-hls_time 10','-hls_list_size 6'\
  
          '-hls_wrap 18','-start_number 1'

  My MP4 attempt -> Main problem (duration is shortened and the later part of the video is speeding by)

         '-y','-ss 0','-b 800k','-vcodec libx264','-acodec mp3'\
  
         '-ab 128','-ar 44100','-bufsize 62000', '-maxrate 620k'\
  
         metaDuration,tDuration,'-f mp4','-movflags','frag_keyframe+empty_moov'

  Second MP4 attempt : -> Main problem (duration is shortened and the later part of the video is speeding by)

      '-y','-vcodec libx264','-pix_fmt yuv420p','-b 1200k','-flags +loop+mv4'\
  
      '-cmp 256','-partitions +parti4x4+parti8x8+partp4x4+partp8x8+partb8x8'\
  
      '-me_method hex','-subq 7','-trellis 1','-refs 5','-bf 3','-coder 1'\
  
      '-me_range 16','-g 150','-keyint_min 25','-sc_threshold 40'\
  
      '-i_qfactor 0.71','-acodec mp3','-qmin 10','-qdiff 4','-qmax 51'\
  
      '-ab 128k','-ar 44100','-threads 2','-f mp4','-movflags','frag_keyframe+empty_moov'])

  Here is an example of the FFMPEG log running with these settings :

  Lastly this is my node code fireing up FFMPEG. (I use the module Fluent-ffmpeg : https://github.com/schaermu/node-fluent-ffmpeg )

      var proc = new ffmpeg({ source: movie, nolog: true, timeout:15000})                         
  
          .addOptions(['-r 15','-b:v 128k','-c:v libx264','-x264opts level=41','-threads 4','-s 640x480','-map 0:v','-map 0:a:0','-c:a mp3','-b:a 160000','-ac 2','-f hls','-hls_time 10','-hls_list_size 6','-hls_wrap 18','-start_number 1 stream.m3u8'])
  
          .writeToStream(res, function(retcode, error){
  
              if (!error){
  
                  console.log('file has been converted succesfully',retcode .green);
  
              }else{
  
                  console.log('file conversion error',error .red);
  
              }
  
          });

  So to conclude this very long and code heavy question :

  I hope this does not come off as a lazy request, but could someone show/explain to me which FFMPEG settings could/should work on all platforms (modern browsers, Android and iOS) producing a stream of a static file which I can send to a HTML5 player.

  [EDIT] what I need if a generic option isn't available

  And if this is not possible as some posts might suggest, I would love to see a set of FFMPEG settings that get's the job done properly as far as mp4 streaming is concerned. (e.g encoding a streamable mp4).

  The streaming mp4 needs the following

  • A shifted moovAtom
  • It needs to be h264

  Thanks very much for your help !

• Unable to play video processed by ffmpeg

  8 janvier 2023, par Kong

  I have an issue of not being able to play a video that was processed by ffmpeg. I have 6 videos, each of different length but same frame rate that i merge (2 rows 3 columns).

  


  VLC player doesn't run it, using any other players return an error. Below is the code I used to combine the videos. I can't seem to find a solution on Google or Stack Overflow.

• Streaming trouble, ffmpeg unable to find a suitable output format

  9 octobre 2018, par Michael Munyanyi

  FFMPEG for some odd reason won’t allow me to output a stream, it’s odd because I have two computers available and one, which had low CPU was having trouble decoding but the stream worked, so I switched my network cables and I have tried transcoding with the same command and it will not output a stream.

  My command reads

  ffmpeg -i udp://@xxx.x.x.xx.xxxx -f mpegts udp://@xxx.x.x.xx.xxxx

  I also tried

  ffmpeg -i udp://@xxx.x.x.xx.xxxx udp://@xxx.x.x.xx.xxxx

  The error reads

  [NULL @ 000001c95eeb2600] Unable to find a suitable output format for udp://@xxx.x.x.xx.xxxx'
  
  udp://@xxx.x.x.xx.xxxx: Invalid argument"
