• Live Stream using .m3u8 and .ts files with iPhone as server

  26 février 2015, par Bhumit

  I am trying to accomplish a task to live stream from iPhone camera. I have done some research and found that i can use .m3u8 files for streaming live video with should contain .ts(Mpeg-2) files .

  Now the file which i have on my iPhone is .mp4 file and it does not work with .m3u8, so i figured out i will have to convert .mp4 to .ts for that , but i have not succeeded in doing so.

  I found that it is possible to convert video ffmpeg lib as mentioned in this article here. I have successfully imported ffmpeg library but not able figure out how can i use it to convert a video as i am using this for first time.

  One another thing apple documentation says

  There are a number of hardware and software encoders that can create
  MPEG-2 transport streams carrying MPEG-4 video and AAC audio in real
  time.

  What is being said here ? is there any other way i can use .mp4 files for live streaming without converting them from iOS ?

  Let me know if i am not clear, i can provide more information .Any suggestion is appreciated. I would like to know am i on a right path here ?

  EDIT

  I am adding more info to my question, so basically what i am asking is , we can convert .mp4 video to .ts using following command

  ffmpeg -i file.mp4 -acodec libfaac -vcodec libx264 -an -map 0 -f segment -segment_time 10 -segment_list test.m3u8 -segment_format mpegts -vbsf h264_mp4toannexb -flags -global_header stream%05d.ts

  How can i use ffmpeg library to do what this command does in iOS.

• Convert .mp3 to .mov or .mp4 on iPhone SDK

  2 août 2014, par Sebastian

  How are you guys ? I’m working on a little idea I had yesterday and I’m a little stuck with an mp3 conversion.

  At this time, my app does the following :

  1. Receive an input text.
  2. The app generate a speech using an online API and download the generated .mp3 file to the app document’s folder.

  Now I need to convert the .mp3 to .mov or .mp4 and then grab it to the camera roll, so the user can share the video on Facebook, Whatsapp, or wherever he wants.

  Is there some easy and memory friendly way to convert from .mp3 to .mp4 without "writing a video" ?
  Thank you !

  all video are from the same source, going through same compression, from mp4 to mp4

  


  import ffmpeg from 'fluent-ffmpeg'

        ffmpeg(inputPath)
            .output(outputPath)
            .videoCodec('libx264')
            .audioCodec('aac')
            .on('end', () => {
                // ...
            })
            .on('error', err => {
