  4 août 2020, par yejafot

  why im getting the below errors.
Am i done any misconfiguration in the build file ?

  


  Can you change it according, im trying to configure for arm64_v8a (.so) file for android jni in my linux machine. Thanks !

  


  Below is my build file.

  i tried all old version of ffmpeg,ndk with different build files but that didnt work so now im trying this latest ffmpeg-snapshot and ndk21

  


• How to overlay 2 videos, one is main second one is overlaying it, and play sound simultaneously. using FFMPEG in ANDROID STUDIO

  6 août 2020, par Dusan Lilic

  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 :

  


  String[] command = {"-i", mainVideoPath, "-vf",
            "movie=" + overlayVideo + ", scale=300:-1[inner]; [in][inner]overlay=10:10[out]" ,combinedVideoOutput};


  


  and this works but I have 3 problems here.
First, video is rotated by 90 degrees (overlay video), second Audio is played only from main video (I want to play sound from both videos simultaneously), and third overlay video is longer (for example : overlayVideo duration is 10 seconds and main video last 7 seconds) then mainVideo, so i want to final video last as long as mainVideo, as soon as mainVideo finish, overlayVideo should also stop (need to cut it prolly ?)

  


  String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,
            "-filter_complex", "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];[base][wm]overlay=10:10" ,combinedVideoOutput};


  


  Using this command i have 2 problems same as above except video is not rotated here.
I have to say that I'm not very familiar with ffmpeg commands. I was trying to figure it out from documentation link to documentation but without any success.
I know that I'm missing some filters like -map merge or something but can't figure it out.
Thanks in advance !

  EDIT2 :
After adding "-shortest" to command i managed to cut overlay video to be the same length as main video (because overlay video is always longer then mainVideo, "-shortest" take short one duration. So now, command looks like this :

  


      String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,"-filter_complex", 
"[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];[base][wm]overlay=10:10", "-shortest", combinedVideoOutput};


  


  Rotation is good so only need to merge their audios. For now, only mainVideo audio is playing, overlay video audio isn't

  


  EDIT 3 :

  


     String[] command = {"-i", mainVideoPath, "-i", overlayVideo ,
            "-strict", "experimental",
            "-filter_complex",
            "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];" +
                    "[base][wm]overlay=10:10; " +
                    "pan=stereo|c0=2*c0|c1=3*c0[a0];[1:a]pan=stereo|c0=1*c0|c1=4*c0[a1];[a0][a1]amix=inputs=2:duration=first:dropout_transition=2",
            "-shortest" ,combinedVideoOutput};


  


  With this command i managed to overlay videos, and play sound from both of them, rotation is good, but -shortest doesn't work now. Only existing problem now is to make them to last as shorter one (mainVideo is always shorter) ???

  


  EDIT 4 :

  


  This is finally working command

  


          String[] command = {"-i", mainVideoPath, "-i", overlayVideo,
            "-filter_complex",
            "[1:v][0:v]scale2ref=(256/256)*ih/8/sar:ih/8[wm][base];" +
                    "[base][wm]overlay=10:10:shortest=1;" +
                    "pan=stereo|c0=2*c0|c1=3*c0[a0];[1:a]pan=stereo|c0=1*c0|c1=4*c0[a1];" +
                    "[a0][a1]amix=inputs=2:duration=first:dropout_transition=2",
            combinedVideoOutput};


  


  Thanks

  


• ffprobe reports some wrong meta data but only when input is piped in

  17 juillet 2020, par spinkus

  I have a video file and I'm using ffprobe to extract meta data from it. If I save the file to disk and runffprobe everything works fine. However, if I pipe the input into ffprobe most meta data is correct, but some fields, such as width, height, display_aspect_ratio are not correct. ffprobe reports these errors when input is a stream (see full outputs below) :

  


  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x563c3de3c000] stream 1, offset 0x2c : partial file
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x563c3de3c000] Could not find codec parameters for stream 0 (Video : mpeg4 (mp4v / 0x7634706D), none, 1567 kb/s) : unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

  


  


  I tried various settings for analyzeduration and probesize with no change in outcome. I tried piping other even larger MP4 files into ffprobe and the height and width is reported correctly, and I don't get "stream 1, offset 0x2c : partial file" output warning. I think there is may be some issue with this particular file, but if that's the case why does it only cause issues when the file is streamed in ?

  


  Any ideas what the issue is and how to get ffprobe to work same with a pipe as for a file input ?
