  • concatenate mp4 videos with ffmpeg concat demuxer in android

    6 mai 2016, par Ara Badalyan

    I want to concatenate mp4 videos with ffmpeg, the problem is when I want to merge videos taken with Iphone and Android it throws problem

    " Non-monotonous DTS in output stream 0:1 ; previous : 150528, current : 139268 ; changing to 150529. This may result in incorrect timestamps in the output file."

    This is my code

    merge.txt

    file 'iphone.mp4'
    
file 'android.mp4'

    ffmpeg command

    ffmpeg -f concat -i marge.txt -c copy -y merge.mp4

    If I can’t merge this videos how can i make them with same parameters (frame rate, bitrate...) and merge them ?

    P.S I use ffmpeg version 2.4.2 , because I can’t find android ffmpeg library higher then 2.4.2.

  • TV audio extracted using ffmeg does not work in iOS (but it works in the simulator)

    26 janvier 2014, par Genar

    I can process a TV signal (well I have a .ts video which comes from a TV channel), using ffmpeg but the audio cannot be understood in an iPhone/iPad. The most strange is that the audio (and video) works properly in the simulator (and also in an Android real device, but this is another point), but in a real iPhone/iPad device the video is OK but the audio sounds like a metallic box and nothing can be understood.

    I have created the ffmpeg libraries for iOS (I have tried the version 2.0.2 and also the version 2.1.3) using the information provided in the following link :

    Installing ffmpeg ios libraries armv7, armv7s, i386 and universal on Mac with 10.8

    The aforementioned link explains how to create the ffmpeg include folders and the universal libraries which I have included into my project (the libraries created are : libavcodec.a, libavdevice.a, libavfilter.a, libavformat.a, libavresample.a, libavutil.a, libswresample.a and libswscale.a).

    The sampling frequency used is 48000.

    The audio got from ffmpeg is then stored into a buffer and then "inserted" using OpenAL ; but, from the same TV content (the same .ts video file) the audio data which is generated from ffmpeg in an iPhone/iPad is totally different from the audio data generated from ffmpeg in the simulator (which can reproduce both the audio and video perfectly).

    Thanks in advance,

  • How do I convert videos to mp4 for use on Android ? [on hold]

    11 avril 2014, par user3525211

    I am trying to use ffmpeg to convert videos (flv,mov,etc) to mp4 for use on android mobile phones. The conversion seemingly works fine. I can see the mp4s on my iphone. But when I test it out on android phones it does not work. I have been googling this problem for two weeks now and I have tried probably 50 different variations of ffmpeg command lines, but without success. I tried upgrading to the latest ffmpeg on my linux server, but I am not linux savvy and am not sure that it did what it was supposed to. I am at my wits end. Am I going about this wrong ? Is ffmpeg the right tool ? Any ideas ?

    Here is the command line I have used to successfully convert to mp4s that work on iphone :
    ffmpeg -y -i input.mov -s 480x270 -r 30000/1001 -b 128k -vcodec libx264 -vpre slow -vpre ipod320 -acodec libfaac -ac 2 -ar 44100 -ab 128k output.mp4
