FFmpeg-Android | Script and Instructions for building FFmpeg for Android

My use case is roughly equal to, adding a 15-second mp3 file to a ~1 min video. All transcoding merging part will be done by FFmpeg-android so that's not the concern right now.

• User can select any 15 seconds (ExoPlayer-streaming) of an mp3 (considering 192Kbps/44.1KHz of 3mins = up to 7MB)
• Then download ONLY the 15 second part and add it to the video's audio stream. (using FFmpeg)
• Use the obtained output

• Extracting fragment of audio from a url

  RANGE_REQUEST - I have replicated the exact same algorithm/formula in Kotlin using the exact sample file provided. But the output is not accurate (± 1.5 secs * c) where c is proportional to startTime

• How to crop a mp3 from x to x+n using ffmpeg?

  FFMPEG_SS - This works flawlessly with remote URLs as input, but there are two downsides,

  1. as startTime increases, the size of downloaded bytes are closer to the actual size of the mp3.
  2. ffmpeg-android does not support network requests module (at least the way we complied)

So above two solutions have not been fruitful and currently, I am downloading the whole file and trimming it locally, which is definitely a bad UX. I wonder how Instagram's music addition to story feature works because that's close to what I wanted to implement.

as title say I'm trying to overlay 2 videos and play sound simultaneously. So far i managed to put 1 video over another using this command:

I am using this FFMPEG library,

first I am playing the video inside my videoView to make sure that the video path is correct

I asked this question last year. I resolved the issue I had and I implemented the same logic for merging an image with a video, instead of two images. This is running on Android.

Here is the command I'm using currently:

I am using below command to merge videos removing audio-

I am trying to append two .mp4 videos on Android. Following an unsafe file name error with command:

execFFmpegBinary(new String[]{"-y", "-i", path, "-s", "160x120", "-r", "25", "-vcodec", "mpeg4", "-b:v", "150k", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath});

video auto rotate after compress..

is there any solution?

here is lib Link
