• FFMPEG - Correct command line parameters to create a H.264 Streaming MP4 from a set of images

  27 septembre 2021, par Adam

  I have no problems viewing a video created by my current parameters in a HTML5 browser, Flash player, Windows Phone 7, Android Phone, etc. However, they won't display on iPhone or iPad. If I modify the video using Super and select "Enable Streaming" checkbox they work on iPhone and iPad suddenly. We are suspecting that my command line parameters are incorrect for enabling h.264 streaming and are instead generating a "progressive download" video.

  



  I'm pretty new to FFMPEG and don't understand a lot of the parameters. Can anyone help correct my existing parameters, or maybe provide the missing parameters, etc ?

  



  Thanks in advance.

  



  My current FFMPEG command line paramters are :

  



  ffmpeg.exe 
 -r 30 
 -threads 4 
 -f image2 
 -i .\frame%05d.jpg 
 -i audioFile  
 -acodec aac 
 -ab 128k 
 -ar 44100
 -vcodec h264 
 -crf 27 
 -coder 1 
 -flags +loop 
 -cmp +chroma 
 -partitions +parti4x4+partp8x8+partb8x8 
 -me hex 
 -subq 5 
 -me_range 16 
 -g 60 
 -keyint_min 25 
 -sc_threshold 40 
 -i_qfactor 0.71 
 -b_strategy 1

• FFmpeg make mpeg2 ts without discontinuity

  31 mai 2012, par user1427162

  I have many MOV files recorded with iPhone and I want to convert them to mpeg2 TS. I want to use them for live video streaming with HTTP Live Streaming protocol.

  I set my iPhone to continiously send MOV files to server. Every video clip is 5 seconds long. I want to make mpeg2 TS out of them and add their urls to m3u8 playlist.
  I managed to do all of that, but when I try to play the stream VLC player plays only first two files in playlist, and last file in playlist at that moment.
  I searched the internet and I think this has something to do with discontinuity.

  Is there any way to convert multiple MOV files into multiple mpeg2 TS segments without discontinuity ?

  Or maybe I'm doing something else wrong ?
  Here is my ffmpeg command :

  ffmpeg.exe -i input,MOV -f mpegts output.ts

  and here is my m3u8 list :

  #EXTM3U
  
  #EXT-X-PLAYLIST-TYPE:EVENT
  
  #EXT-X-TARGETDURATION:10
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXTINF:10,
  
  fileSequence0.ts
  
  #EXTINF:10,
  
  fileSequence1.ts
  
  #EXTINF:10,
  
  fileSequence2.ts

  Thanks in advance

• youtube_dl, ffmpeg, discord.py is not playing songs even w/o streaming

  27 août 2021, par BlueFire02

  I have tried many times to make a basic queue system, I tested the play command to see if it worked back then and it did, unfortunately during this construction I have been having a lot of problems just playing the song. I did try to implement a queueing system but all that comes out is this specific error :

  


  [tls @ 0x7f8244705240] IO Error: -9806 [https @ 0x7f824480b000] Will reconnect at 835584 in 0 second(s), error=Input/output error.


  


  Additional Info : I also installed ffmpeg onto my mac, I only put the 1 file called ffmpeg in my path if that helps but I am pretty sure it has to do something with youtube_dl.
