FFMPEG, Creating an MPEG-DASH stream with existing inputs
10 septembre 2019, par kitenseiI am trying to generating a
DASH .mpdfile from multiple inputs (2 videos, 1 audio) without any success..What I’d like to do it’s simple getting the streams and create an mpd file without any re encoding since I’ve already my sources ready.
The output seems to work in rxplayer, but I do get a lot of errors (see log below).
Here are my 3 sources (taken from http://dash-mse-test.appspot.com/media.html) :

FFmpeg mosaic video creation, Why it doesn't work ?
3 mai 2019, par Ege DarçınI am trying to build a mosaic from multiple videos in an android application using FFmpeg, I have found the wiki on how to do it. The link explains the process well but I am getting this error while processing it :
I/Videokit : start run in main.
register_exit
term_init & parse options.
D/Videokit : ERROR OCCURED
The library that I’m using is WritingMinds, which is FFmpeg for Android compiled with x264, libass, fontconfig, freetype, fribidi and lame (Supports Android 4.1+). Basically, you write a string array of code which is passed to FFmpeg and it runs FFmpeg for you.
Clearly, it is a parsing error but I believe that I have put the command in order. I have tested the files, locations and FFmpeg with other commands like trim, mute audio etc and only mosaic doesn’t work. I have tried different options, string manipulations but that didn’t work, Furthermore, I’ve seen OpenGl error if I put a big typo error.
Here is the code on the wiki :-i 1.avi -i 2.avi -i 3.avi -i 4.avi
-filter_complex "

FinalPath.toString()};
execFFmpegBinary(m);This is the string that I send to the FFmpeg.
The expected result would be a video created on the "FinalPath" which is on the external storage. However, I am getting an error message and nothing else. I have a tight deadline so it would be hard for me to switch to another system and learn it, I’m already new to FFmpeg stuff. Any suggestions ?
Update : I’ve implemented error handlers of the library, not just FFmpeg part, and it points reports as (’"nullsrc’ is not a filter) . However, I need to put (") into there to run the code and I use it as (\"), which does not solve the problem. Removing them is not an option because the statement after the filter needs the quotation marks.
Update2 : Here is the current log :

}program fails while accessing integrated loudness in dump_ebur128_context.can someone guide me about , how I should proceed in here.
