• Best way for stream videos on web [on hold]

  13 février 2016, par Amir

  I am working on video-sharing website and looking for Appropriate way to stream videos because all users can send video in my site. I wonder which way is best to stream all videos like YouTube, compatible with all speed and all the qualities and can change quality . breathed apple hls finally arrived, but the only problem is that for the video to the must take into consideration multiple video files . ffmpeg seagment that the server takes up this much volume.

  The second way that came to my mind is live transcoding. It does not change its quality by changing the speed of video, but this version was with JavaScript wrote such a thing. Speed and space as large as any video website YouTube will be more suitable, but when I thought this was the way all the server and does not work. Most importantly, when you upload a video to YouTube you see it say the process is completed so it means YouTube will not use this method. I think YouTube very easy to convert several formats witout seagment . change the quality generated script that was said !!

  In your opinion, when is the most appropriate way ?!
  Thankful

• How to use PHP FFMPEG to alter audio binary header bytes offset

  27 mai 2019, par SomniusX

  I use the following method to create a WNB file that is flashable to my Electric Unicycle Ninebot Z10

  First audacity to make the file raw pcm 16khz 16bit mono littleendian
  Then wnb-slicer golang app to convert that raw file into wnb.

  Today i did the same with ffmpeg

  ffmpeg -i $1 -acodec pcm_s16le -f s16le -ac 1 -ar 16000 -acodec pcm_s16le $1.raw
  
  ../wnb-slicer-master/wnb-slicer -file-name $1.raw

  where $1 is the original file

  About an hour ago i did the ffmpeg part with php-ffmpeg but i can’t have golang run on a webserver.

  So i thought if ffmpeg does bytes manipulation like the golang app does here

  Thank you in advance !

  p.s. this project will help all electric unicycle owners of the Z series wheels to change audio voices/sounds on their wheels !!

• Video editor for android - FFmpeg won't compile on windows ?

  4 décembre 2014, par Zoe

  Im trying to make a video editor for android (I’ve never made an android app before)

  After searching for libraries to use I came across FFmpeg but I’m having trouble getting it to compile on Windows 7.

  I’m currently using Eclipse and have the most recent android SDK and ndk.

  I’ve been trying to follow tutorials on the internet including roman10’s (http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/) but they all seem specific to Linux.

  Yesterday, I thought I’d give up and just dual boot Ubuntu on my windows laptop but of course that was messing up too. I shrank my partition and booted Ubuntu of a USB but the installer was detecting there is no OS on my laptop and not giving me the option to install it alongside windows 7.

  So, can FFmpeg be compiled for android on windows ? Or is there another library I could use to make a video editor that can ?

  Or should I just persist with dual booting ubuntu ?

  Thanks
