• ffmpeg : How to get ffmpeg to ignore or fill in missing frames in the input image sequence [closed]

  6 février, par Greg E

  I have input frames image.0001.png, image.0002.png etc. Converting them to mp4 with

  


  ffmpeg -f image2 -i image.%04d.png -vcodec libx264 -crf 1 -pix_fmt yuv420p out.mp4

  


  However if there are missing frames in the sequence, eg. image.0020.png is missing, ffmpeg stops at frame 19 and makes a truncated movie with 19 frames.

  


  I'd like ffmpeg to just ignore the missing frame 0020, or repeat 0019 as 0020, or anything else sensible (look ahead and pull 0021 back to be 0020 ?).

  


  For context, this is a moving geometric art thing and a skipped frame will be a noticeable jerk in the movie, probably a repeated frame will be smoother.

  


  Thanks for any assistance.

• creating video from images with FFmpeg with android and FFmpeg integrate it with my windows environment,

  2 janvier 2015, par Hussnain Muavia

  Excuse me i have setup my eclipse with android NDK r10d, install CDT, and also GIT. I have search a lot about FFmpeg to integrate it with my windows environment, and i have found so many solutions for linux platforms, but failed to set it on windows. I also search some source with guardian project from GITHub and found very useful information from there about how to implement source of ffmpeg on android.
  I don’t want to install linux on my PC or other such solutions to getting my point because i have already wasted my a lot of time. So i just download a project from GITHub and copy all necessary files that can use for building app with ffmpeg on android correctly, like JNI folder *.so files, Android.mk file , build.sh file and such other necessary files. And i replace NDK root path from my directory in Build.sh
  So i just want to ask from you guys, is this thing OK for Windows to do this ? because i never run any cmd command to get these files
  I mean i have found so many solutions where every one mentions that we have to run some terminal commands on linux to setup and produce these files for android environment. So please guide me.

  I tried to convert a mp4 file into an audio mp3 file only. I found ffmpeg and read a lot about this error message but I couldn't find a solution.

  ffmpeg.exe -i 2026857739212839680.mp4 output_file.mp3
ffmpeg.exe -i 2026857739212839680.mp4 -vn -b:a 128k -c:a libmp3lame output_file.mp3


  


  Always I receive the message about the invalid argument... I can see none.
