• FFmpeg with Swift 3 in iOS

  5 octobre 2017, par Rahul Patil

  I am working on one application where I want to show video stream from ip enabled camera. There is one URL where that video I want to show in app.
  I am new for this task and I don’t know anything about what to do.

  After trying and searching I found a solution with Objective-C, having a sample project which the ffmpeg lib is configured.

  If anyone have ideas about how to work with ffmpeg using Swift or anyone have sample code then please share with me.

• how to use ffmpeg to apply 1:1 SAR before concat on large complex filter

  24 avril 2019, par 2c2c

  I use ffmpeg to concat videos in a fashion similar to this :

  I ran into a weird error with my inputs

  [Parsed_concat_0 @ 000000002a05bb80] Input link in10:v0 parameters (size 1280x720, SAR 2049:2048) 
  
  do not match the corresponding output link in0:v0 parameters (1280x720, SAR 1:1)

  From what I’ve researched I need to use setsar to force all the videos to be 1:1 before I concat, but I’m not sure how to do that in my filter.

• Terminal command to upgrade FFMPEG

  14 avril 2023, par Savvy Turtle

  Everything is still installed but once I upgraded my server from CentOS 7.6 to Cloud Linux FFMPEG does not seem to work anymore.

  


  When I go and debug it in the admin section where you upload a test video and hit debug it shows a toast to upload a video. and on the front end of https://turtle.tube/ users upload a video and it gets stuck at 100% upload and processed.

  


  So I'm wondering whether I need to ugrade FFMPEG to work with Cloud Linux update or If I need to restart it.

  


  Any help would be great thanks.

  Checked Version, looked for terminal command to upgrade FFMPEG to latest stable release of : FFmpeg 5.1.3 "Riemann" or FFmpeg 6.0 "Von Neumann" but have not figured out the command to upgrade yet.

  


  nor the command to restart FFMPEG if that even exist.

  


  Current version of FFMPEG shows :

  


  ffmpeg -version
