• FFmpeg mosaic video creation, Why it doesn't work ?

  3 mai 2019, par Ege Darçın

  I 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 "
  
          nullsrc=size=640x480 [base];
  
          [0:v] setpts=PTS-STARTPTS, scale=320x240 [upperleft];
  
          [1:v] setpts=PTS-STARTPTS, scale=320x240 [upperright];
  
          [2:v] setpts=PTS-STARTPTS, scale=320x240 [lowerleft];
  
          [3:v] setpts=PTS-STARTPTS, scale=320x240 [lowerright];
  
          [base][upperleft] overlay=shortest=1 [tmp1];
  
          [tmp1][upperright] overlay=shortest=1:x=320 [tmp2];
  
          [tmp2][lowerleft] overlay=shortest=1:y=240 [tmp3];
  
          [tmp3][lowerright] overlay=shortest=1:x=320:y=240
  
      "
  
      -c:v libx264 output.mkv

  This is the code which is on the wiki

  String[] m =new String[]{"-i",
  
                  DestPath1.toString(),
  
                  "-i",
  
                  DestPath2.toString(),
  
                  "-i",
  
                  DestPath3.toString(),
  
                  "-i",
  
                  DestPath4.toString(),
  
                  "-filter_complex",
  
                  "\"",
  
                  "nullsrc=size=640x480 [base];",
  
                  "[0:v] setpts=PTS-STARTPTS, scale=320x240 [upperleft];",
  
                  "[1:v] setpts=PTS-STARTPTS, scale=320x240 [upperright];",
  
                  "[2:v] setpts=PTS-STARTPTS, scale=320x240 [lowerleft];",
  
                  "[3:v] setpts=PTS-STARTPTS, scale=320x240 [lowerright];",
  
                  "[base][upperleft], overlay=shortest=1", "[tmp1];",
  
                  "[tmp1][upperright] overlay=shortest=1:x=320 [tmp2];",
  
                  "[tmp2][lowerleft] overlay=shortest=1:y=240 [tmp3];",
  
                  "[tmp3][lowerright] overlay=shortest=1:x=320:y=240",
  
                  "\"",
  
                  " -c:v",
  
                  "libx264",
  
                  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 :

• FFMPEG Optional Entries in -var_stream_map

  16 juillet 2022, par Baa

  I have a script that records an x11 display and outputs three HLS streams.

  



  ./ffmpeg -y \
    -f x11grab -framerate 60 -s 1920x1080 -i :1.0 \
    -c:v:0 libx264 -c:s:0 copy -c:a:0 aac -b:v:0 4000k -b:a:0 512k -s:v:0 1920x1080 -r:0 30 -g:0 90 -preset:0 superfast -tune:0 zerolatency -level:v:0 4 -f flv \
    -c:v:1 libx264 -c:s:1 copy -c:a:1 aac -b:v:1 2500k -b:a:1 256k -s:v:1 1280x720 -r:1 30 -g:1 90 -preset:1 superfast -tune:1 zerolatency -level:v:1 4 -f flv \
    -c:v:2 libx264 -c:s:2 copy -c:a:2 aac -b:v:2 800k -b:a:2 256k -s:v:2 960x540 -r:2 30 -g:2 90 -preset:2 superfast -tune:2 zerolatency -level:v:2 4 -f flv \
    -hls_time 6 \
    -hls_list_size 2 \
    -hls_flags delete_segments \
    -map 0:v -map 0:a? -map 0:s? -map 0:v -map 0:a? -map 0:s? -map 0:v -map 0:a? -map 0:s? \
    -var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2" \
    -f hls -master_pl_name "${name}.m3u8" \
    -hls_segment_filename "/tmp/hls/${name}_%v-%d.ts" \
    -max_muxing_queue_size 1024 \
    "/tmp/hls/${name}_%v.m3u8"


  



  This line :

  



  -map 0:v -map 0:a? -map 0:s? -map 0:v -map 0:a? -map 0:s? -map 0:v -map 0:a? -map 0:s? \


  



  Has question marks after each 0:a, this is because the input does not always have audio, so it ignores the error when there is no audio present, and maps it when there is.

  



  However, the following switch :

  



  -var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2" \


  



  Will only work if there is audio present, is there a way I can have -var_stream_map with entries that will ignore errors like -map does ?

  



  Here are the errors if I try to use this current script with no audio :

  



  [hls @ 0x6231800] Unable to map stream at a:0
[hls @ 0x6231800] Variant stream info update failed with status ffffffea

• ffmpeg android java. Unable to use single and regular quotes

  14 février 2016, par MalusDarkb

  First off, in the long run I want to implement a speedometer for a MP4 file using Android. I did some research and apparently the best way to do that is through FFmpeg. I decided on using this library : https://github.com/WritingMinds/ffmpeg-android-java . It implements FFmpeg for Android. It was quite simple to include into my project. (Instructions : http://writingminds.github.io/ffmpeg-android-java/)

  I use the following method. As cmd I am using a String in Quotations marks

      ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
  
      ...
  
      };

  Now I was trying to overlay some dynamic text over an MP4 file. I thought I would start trying it with a timestamp. For a timestamp something like this is needed : ... timecode=’02:36:17~;00’ ...

  My Problem is I am getting this error " Unable to find a suitable output format for ’’’. It doesn’t matter if i try to use "\" (escaping) or if i try to use regular quotes. Whenever I use some kind of quotation mark I am getting an error. That makes it impossible to use an dynamic timestamp. I think.

  Does anyone have an idea as to how I can fix this ? Keep in mind the timecode is within a String in an Android(Java) class.

  Thanks in advance for your help

  EDIT :

  Can someone provide me with a working command ? The cmd 1-3 work, but 4 and 5 don’t work (even as String[]).

      String cmd1 = "-i /storage/emulated/0/dir1/dir2/TestVideo.MP4 -i /storage/emulated/0/dir1/dir2/logo.png -preset ultrafast -filter_complex overlay=10:main_h-overlay_h-10 -acodec: copy /storage/emulated/0/dir1/dir2/LogoOverlay1.mp4";// working PNG overlay

  cmd4arr and cmd5arr create an new MP4 file. But it has a size of 0KB. The commands seem not to process the frames at all. It always stops with this last line of the Log posted above.

  Edit :

  Answered question : "What how can I use a String [ ] with this Library ? Information on that might fix the other issues."

  Answer : I imported the project as arr before. When it is imported as a regular library you can’t use a normal String anymore but it is implemented as an String[].
