  ffv1dec : move slice decoding into a separate function
  This simply movies all slice decoding code from decode_frame
  
  to decode_slices ; nothing more.

• FFmpegKit : "Operation not permitted" in many android devices [closed]

  26 août 2023, par Mrm

  I'm using FFmpegKit 5.1.LTS in my application. A lot of my users have reported that they cannot edit videos (10%). When I tried to obtain their logs, I noticed that many of them are encountering an 'Operation not permitted' error. My users have granted all the necessary storage permissions (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE).

  


  Here is an example :

  


  User device :

  


  Manufacturer : Sony
  
Model : SOG05
  
ABI : [arm64-v8a, armeabi-v7a, armeabi]
  
Android SDK : 33

  


  Command :
ffmpeg -y -ss 12.789 -to 32.654  -i "/storage/emulated/0/Movies/lts/lts_20230824_100739.mp4" -filter_complex "[0:v:0] scale=1080:2520,setsar=1/1[v0];[0:a:0]atempo=1.0,volume=1.0[a0]; [v0] [a0] concat=n=1:v=1:a=1[conv][cona];[conv] drawtext=fontfile=/system/fonts/Roboto-Regular.ttf:text=lts edit:x=(w-text_w-69.55932):y=(h-text_h-36.61017):fontsize=84:fontcolor=white:shadowcolor=black:shadowx=5.4915257:shadowy=5.4915257[conv]" -map "[conv]" -map "[cona]"  -c:v libx264 -force_key_frames 'expr:gte(t,n_forced*1)' -preset ultrafast  -r 30  -shortest /storage/emulated/0/Movies/lts/lts_20230826_092915_edited.mp4

• FFMpeg command doesn't works for 4.0-39-gda39990 version but works for 3.0.1 version

  17 mai 2020, par Android Developer

  I run below FFmpeg command to cut video using 4.0-39 version-

  



  {"-y","-i","/storage/emulated/0/Movies/g3cm1tt7qtd41.mp4.mp4", "-ss", "10", "-t", "53", "-c", "copy","/storage/emulated/0/Movies/cut_video10.mp4"}


  



  It returns success with below response but the output video cannot be played !However same command runs fine when using older version 3.0.1 of FFMpeg and output video can be played !
