• Video Failed to transcode with FFmpeg with Rails app in my localhost

  25 avril 2017, par Takor

  I ve tried to upload videos using Carrierwave-video & FFmpeg. I’ve installed FFmpeg and there is no problem with installation. I have made configurations from ’ http://blog.41studio.com/upload-videos-using-carrierwave-ffmpeg/ ’ .But when I tried to upload video (.mov file), I have an error.

  Error

• Android : Select from images extracted with FFMPEG

  21 juillet 2017, par Tix

  I’m currently able to extract images(frames) from a video, and display all the extracted images using the code below, how do i make it so that the displayed images could be selected by user and passed as a bitmap to another activity ?

  FFMPEG Compiled using

  compile ’com.writingminds:FFmpegAndroid:0.3.2’

  Complex Command used to get the frames/images

  String[] complexCommand = "-y", "-i", yourRealPath, "-an", "-framerate", "60", "-vf", "select=’gte(n,45)’", "-vsync", "0", dest.getAbsolutePath() ;

• How is FFMPEG taking longer than 30 seconds with timeout set ?

  5 mars 2020, par Dave Stein

  I’m running FFMPEG within a lambda set for 30 second expiration.

  I run this command :

  ffmpeg -loglevel fatal -timelimit 15 -timeout 10 -protocol_whitelist file,http,https,tcp,tls,crypto -i https://www.location.com/manifest -vframes 1 myimage.jpg -y

  timeout seems superfluous as a command for waiting for incoming things, while I am scraping. I did that as just super cautious cause I saw a time limit with something for RTMP : https://ffmpeg.org/ffmpeg-protocols.html#rtmp

  timelimit is supposed to bail out of FFMPEG (https://www.ffmpeg.org/ffmpeg.html#Options) :

  Exit after ffmpeg has been running for duration seconds in CPU user time.

  My logs in my lambda fire up until this point and then I get a timeout. Is there any other option I might be missing ? I am really confused given that timelimit bails after running X seconds
