• android ffmpeg halfninja av_open_input_file returns -2 (no such file or directory)

  20 janvier 2012, par cdavidyoung

  I have built ffmpeg for Android using the code and method described at

  https://github.com/halfninja/android-ffmpeg-x264

  using Ubuntu running in VirtualBox on windows. I then copied libvideokit.so into the Project\libs\armeabi folder of a Windows copy of the provided projects. From there I was able to run the ProjectTest from Eclipse on my Android device. I can see the ffmpeg code being executed but when it gets to the point of opening the input file it gives me the indicated error. I have noticed some discussion of this problem at

  FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line

  but the solutions have not helped since the file protocol is enabled in this build and I also tried putting "file :" in front of the filepath to no avail. For completeness I tried setting minimal_featureset=0 to enable all the defaults but this gives me the same error. Below is a snapshot of the logcat from Eclipse showing the output from Videokit with an extra call to LOGE to display the result from av_open_input_file. Any suggestions of things to try would be greatly appreciated.

• How can I write to file with video state while paused in ffplay

  26 août 2014, par pixelearth

  Can anyone recommend a way to do what I need : I need to go through 2000+ videos and choose an accurate thumbnail frame down to the .xx decimal place.
  Ffplay works great for this, but it’s tedious to manually copy paste this value from the terminal into my database. It would be great if I could hit a key sequence or somehow trigger an event that would write information about ffplay’s current state (filename, location) to a file.

  Is there a way once the video is paused to somehow write to a file with the filename and location ?

• ffmpeg rotate and resize

  23 août 2014, par user1321964

  I’m trying to resize a movie and to rotate it counter-clockwise using ffmpeg.
  I can achieve one or the other ok individually

  ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

  OR

  ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

  but if I try to do both, either-

  ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

  ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV

  OR

  ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

  ffmpeg -i rotate.MOV -s 406x720 toutp.MOV

  the final movie does not play, only audio, no video ; neither previewing in Finder, nor in Quicktime. More seriously once I have attempted to play it, I can’t then play any other movie whatsoever (only audio) - quicktime won’t quit, constantly need to force-quit it. The only way to then restore seems to be reboot OS-X

  This though does work -

  ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

  ffmpeg -i rotate.MOV -s 720x406 toutp.MOV

  but doesn’t do what I want - it stretches the movie in the wrong direction

  Any ideas ?
