  • 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 ?

  • FFMPEG combining 2 command to make multiple overlay [closed]

    11 avril 2020, par Nano Wibisono

    I have two different commands and both work. but here I have a problem, how to combine these two commands into one output

    



    the first command is to add a video overlay

    



    ffmpeg -i   final.mp4    -vf "movie=LOGO.mov, scale=100: -1 [inner]; [in][inner] overlay =10: 10 [out] " completed.mp4


    



    the second command is to add a text overlay

    



    ffmpeg -i final.mp4 -vf drawtext="fontfile=C\\:/Windows/Fonts/arial.ttf:fontsize=20: fontcolor=red:x=10:y=50:text='test tect'" completedtextGB.mp4


    



    I was wondering is it possible to combine these into the 1 command ?

    



    Thanks
Nano
