• FFMPEG Update Command For Android 7

  4 juin 2019, par user2401847

  I have 300 images and i want to generate video from these images with Audio

  i am using below command to generate video

  ffmpeg -framerate 15 -i img_%d.jpg -i logo.png -i inputfile.mp3 -filter_complex \
  
  "[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" \
  
  -vcodec libx264 -crf 25 -map 2:a -c:a copy -pix_fmt yuv420p -shortest test_video.mp4

  Which generates video with audio but video is not working for android 7 and above

• Android MediaExtractor crash when decoding some mp4 files. Libc fatal signal 11

  23 octobre 2015, par wonglik

  I am using Google Grafika examples to display video on TextureView. "Double decode" to be more specific . Code work most of the time but for some mp4 files it crash giving only :

  libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 7998

  Same code works for webM files and most mp4 files. Place where I expect it to fail is :

  extractor = new MediaExtractor();
  
  extractor.setDataSource(sourceFile);

  in MoviePlayer [L:113]

  Any hint how to walk around or what might be the problem ?

• ffmpeg library take long encoding time

  11 février 2019, par robinson george

  I am making an android app in which user can insert a images and its turned into a video. I tried making a video over the photos(selected by user) with replacing green colour in video using ffmpeg library. But the results are not very satisfying and it’s take around 4-5 seconds to encode a video of around 15 seconds. There are already many apps present in play store but i was wondering how they achieved this effect in so much lesser time(like < 1 sec to encode 15 sec video).
