How do I convert videos to mp4 for use on Android ? [on hold]
11 avril 2014, par user3525211I 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 -
TV audio extracted using ffmeg does not work in iOS (but it works in the simulator)
26 janvier 2014, par GenarI 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,

concatenate mp4 videos with ffmpeg concat demuxer in android
6 mai 2016, par Ara BadalyanI 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.
