• FFmpegRecorder for recording Android videos from Camera

  28 novembre 2013, par Chirry

  1. I have seen the FFmpegRecorder class from FFMpeg in some files related to openCV for recording videos, specifically in FFmpegFrameRecorder class from OpenCV. How can I use this class or a similar one without using openCV ?

     As far as I have read, when you make an App using openCV, the final user will have to download some libs into his device and that is why I don't want to use OpenCV.

  2. If there is a way to make an App using openCV in which the final user don't have to download anything I would like to know it.

• Audio async after using setpts, converting to ts and concatenating

  11 janvier 2018, par Aurelius Schnitzler

  I am using f.i.

  ffmpeg -y -ss 00:00:09.664 -t 00:00:06.939 -i "test.mp4" -an -c:v libx264 -filter:v "setpts=0.1*PTS" test2.mp4

  to speed up a video by 10.

  But there is still audio in it when being used with

  ffmpeg -y -i test2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 2f.ts

  and

  ffmpeg -y -i "concat:2f.ts|..." -bsf:a aac_adtstoasc -movflags faststart -c copy final.mp4

  later on, yet every part’s audio in the final video is async.

  In some videos added with concat the video is not sped up, ie no -filter:v "setpts=0.1*PTS" and the audio is kept, ie no -an as in

  ffmpeg -y -ss 1 -t 2 -i "test3.mp4" -an -c:v libx264 test4.mp4
  
  ffmpeg -y -i test4.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts 4f.ts

  How do I mute the sped up parts and have audio not be async in the final video ?
