ffmpeg-android | Sample Android application using FFmpeg

Use the shortest option in the overlay filter:

Alright After some digging around it turns out that I was supposed to give a path and a name to the FFmpeg to create the file for me and save the data inside that file, I shouldn't create the file and give it the file path because FFmpeg will try to overwrite that file with the one it is trying to create, by default FFmpeg doesn't have permission to overwrite it,lastly, you should also add the file extension (I was saving the file without the extension)

So what is the solution? you can simply give a path to where you want to the FFmpeg to create the file but without creating the file yourself like so

You can try forcing the level to 4.0 with the -level 4.0 option.

Try

You have to concat the filtered streams, not the source streams, so change the input labels i.e.

[v0] [v1] concat=n=2:v=1:a=0

Add -an to remove audio.

Separate the option and value i.e. "–safe", "0"

it might be the autorotate issue in FFMPEG and you have to disable autorotate:

If you change each timestamp (Presentation Timestamp, PTS) to be half of its original value, your video will be half as long.

So, if the PTS is x * PTS, then your final duration will be x * duration.

Example:

I know I am posting my own question, but it might help others in future.

In my question, I am passing initial time at beginning of command line so ffmpeg didnt recognize it.

Below is corking commands:

I ended up using the scripts from this project that uses all latest NDK and ffmpeg together with every latest library, in order to create an ffmpeg binary. It works pretty well on my device and by modifying a bit, I got a static ffmpeg as well. I only needed to add 2 extra native libraries to my app for it to work. It even uses all CPU features so it is the fastest solution for mobiles.
