• Android crashes when new FFmpegFrameRecorder()

  23 mai 2021, par James Yu

  I try to create rtsp stream (or video file) with bitmaps using FFmpegFrameRecorder, and I get this message in logcat at the very beginning of the process :

  


  Thread[6,tid=2010,WaitingInMainSignalCatcherLoop,Thread*=0x795a268000,peer=0x12ec00b8,"Signal Catcher"]: reacting to signal 3


  


  and get

  


  SIGILL (signal SIGILL: illegal instruction)


  


  in debug tag, then my app hangs after these message shows up.
It is confirmed this SIGILL pops when new FFmpegFrameRecorder() is invoked, I wonder why it complains illegal instruction ?

  


  This is how I create an instance of FFmpegFrameRecorder :

  


      private void startRecorder() {
        if(recorder != null) { return; }
        recorder = new FFmpegFrameRecorder("/sdcard/test.flv", 640, 480, 0);
        recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
        recorder.setFormat("flv");
        recorder.setFrameRate(25);
        recorder.setInterleaved(true);
        recorder.setVideoOption("crf", Integer.toString(25));
        recorder.setPixelFormat(0);
        recorder.setGopSize(-1);
        recorder.setVideoOption("tune", "zerolatency");
        recorder.setVideoOption("preset", "ultrafast");
        try {
            recorder.start();
        } catch (FFmpegFrameRecorder.Exception e) {
            Log.e("sensetime", e.getMessage(), e);
        }
    }

• FFMPEG Error Code : "Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_scale_10" ; [complex_filter], [-loop 1], [overlay]

  30 août 2020, par Leroy Freyler

  I'm currently experimenting a bit with ffmpeg around.

  


  I want to produce a video that has a .jpg background image over which several videos are overlaid.

  


  Currently I can overlay a black background with any number of videos. But I'm trying to add a static image to the background and then it doesn't work anymore.

  


  My FFMPEG command line is

  


  command = f"ffmpeg -loop 1 -i background.jpg -i vid1.mp4 -i vid2.mp4 -i vid3.mp4 -i vid4.mp4 -filter_complex "nullsrc=size=1920x1080 [base]; 
    [0:v] setpts=PTS-STARTPTS, scale=320x240 [low]; 
    [1:v] setpts=PTS-STARTPTS, scale=320x240 [upperleft]; 
    [2:v] setpts=PTS-STARTPTS, scale=320x240 [upperright]; 
    [3:v] setpts=PTS-STARTPTS, scale=320x240 [lowerleft]; 
    [4:v] setpts=PTS-STARTPTS; scale=320x240 [lowerright]; 
    [base][upperleft] overlay=shortest=1 [tmp0]; 
    [tmp0][low] overlay=shortest=1:x=420:y=240 [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 will generate the following error message

• FFMPEG av_interleaved_write_frame() : Operation not permitted

  21 décembre 2020, par camslaz

  Ok I receiving a 'av_interleaved_write_frame() : Operation not permitted' error while trying to encode an MOV file. Firstly I need to outline the conditions behind it.

  



  I am encoding 12 different files of different resolution sizes and format types via a PHP script that runs on cron. Basically it grabs a 250mb HD MOV file and encodes it in 4 different frame sizes as MOV, MP4 and WMV file types.

  



  Now the script takes over 10mins to run and encode each of the files for the 250mb input file. I am outputting the processing times and as soon as the time on the script hits 10mins FFMPEG crashes and returns "av_interleaved_write_frame() : Operation not permitted" for the current file being encoded and all other remaining files yet to be encoded.

  



  If the input videos is 150MB the total time the script runs for is under 10mins so it encodes all of the videos fine. Additionally if I run the FFMPEG command on the individual file that it fails on for the 250mb file it encodes the file with no issues.

  



  From doing to research on the error "av_interleaved_write_frame()" it seems it is related to timestamps of what I understand to be of the input file. But in saying that it doesn't seem to be the case in my instance because I can encode the file with no problem if I do it individually.

  



  example ffmpeg command

  



  ffmpeg -i GVowbt3vsrXL.mov -s 1920x1080 -sameq -vf "unsharp" -y GVowbt3vsrXL_4.wmv


  



  Error output on the failed file at 10mins. Remember there is no issue with the command if I run it by itself it is only when the script hits 10mins.

     )


  



  Has any anybody encountered this sort of problem before ? It seems to be something to do with the timestamps but only because the script is running for a period longer then 10mins. It maybe related to PHP/Apache config but I don't know if it is FFMPEG or if it is server config I need to be looking at.
