• FFmpeg convert single image into video Android

  15 mai 2014, par berserk

  I am trying to convert a single image into a video using FFmpeg. I have tried following the files :

  "ffmpeg  -analyzeduration 2147483647 -probesize 2147483647 -i " + packat.get(i).path +"-r 25 -t 1000 -y op.mp4"
  
  
  
  "ffmpeg -loop 1 -r 23.976 -i input.jpg -t 00:00:02 -vcodec qtrle -an output.mov"
  
  
  
  "ffmpeg -i c:\rawvideo\mask.bmp -loop 1 -r 29.97 -s 720x480
  
          -aspect 4:3 -t 00:04:05 -vcodec mjpeg -vb 11261600 -an
  
          c:\rawvideo\fullmask.avi"

  But all of them give me this annoying error :

   Can not process SOS before SOF, skipping marker parser used 0 bytes (0 bits) decode frame unused 0 bytes decoding for stream 0 failed 
  
  Could not find codec parameters for stream 0 (Video: mjpeg): unspecified size
  
  Consider increasing the value for the 'analyzeduration' and 'probesize' options /storage/sdcard0/cblVE/temp/0.jpg: could not find codec parameters 
  
  exit_program: 1 

  Please help. I have searched for a solution from a week, but I have found nothing.

• Capture video stream with FFmpeg

  14 mars 2013, par rickster

  I wrote an android app that sends a live video stream from the camera over a socket to my computer. Is it possible to use FFmpeg to decode the MPEG4 video stream and some how display what the camera is seeing in real time ? I'm guessing I would have to create a bitmap from the latest information it had from the byte stream and display it on the computer at 20+ FPS.

  How would I go about doing something like this ?
  C++, C# or Java is fine. From my understanding FFmpeg is written in C++

• Unknown OS 'msys_nt-6.1'. using Mingw on win7 64bit

  6 juillet 2018, par user63898

  I try to compile FFmpeg from source using MSYS2 and MIngW I’m using win7 64 bit .
  using .

  $ ./configure --enable-shared

  I’m getting this error :

  Unknown OS 'msys_nt-6.1'.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solve the problem.

  looking in to config.log
  i see ( the end of the log ) :
