• FFMPEG realtime streaming using a remote m3u8

  8 avril 2016, par JJ The Second

  Good morning chaps,

  I’ve been doing a long term research to do DRM solution for my client and we are almost there, here is what we’d like to achieve and please accept my lack of understanding, Im well new to FFMPEG and there are so many questions already asked but I’m not sure if they cover my questions.

  Objectives :

  1- To record and stream (real-time) m3u8 from a remote server : We have access to more than 3000 HLS streams (b2b project) therefore we would need to record and stream m3u8 in real-time. Currently I am able to record to mp4 or mkv but don’t understand how to stream real time

  2- Stream using HL264 : We would need to make sure streams play on all devices, based on my understanding this is the correct format to use, is this correct, more than happy to hear your comments

  3- Delivery to be in 3 different resolutions, HD, 488 and 380 : This is all about sizes, it is unlikely that my users would stream using mobile devices (GA says only 32000 using mobile) but still I need to make sure there are no restrictions to users

  Questions :

  1- I’ve seen lots of tutorials with regards to recording m3u8, converting to mp4 or .ts files, so I’m not sure how this works, do I need to export my recording to .ts files and merge them again ? If this is the case, isn’t this going to have delay in streaming ?

  2- By doing this, am I using my bandwidth or source of m3u8 ?

  3- If converting to .ts then would you please let me know how I can achieve this ?

  Please note, my recording are (for now) all m3u8 and I need to stream as m3u8 at the same time.

  I have latest version of FFMPEG installed on Ubuntu 14.4 TLS

  Thank you all in advance and happy Friday !

• I want help in making video collage, tried everything but unsuccessful

  I want to make Video Collage in which 2 or more videos should be displayed in one frame and then they can be converted into one Video file.
  I tried examples but they just add videos at the end of each video to make a long one combine video.
