• Unplayable video after running FFmpeg command

  25 mai 2020, par HB.

  I asked this question last year. I resolved the issue I had and I implemented the same logic for merging an image with a video, instead of two images. This is running on Android.

  



  Here is the command I'm using currently :

  



  "-i", mFilePath, "-i", drawingPath, "-filter_complex", "[0:v]scale=iw*sar:ih,setsar=1,pad='max(iw\\,2*trunc(ih*47/80/2))':'max(ih\\,2*trunc(ow*80/47/2))':(ow-iw)/2:(oh-ih)/2[v0];[1:v][v0]scale2ref[v1][v0];[v0][v1]overlay=x=(W-w)/2:y=(H-h)/2[v]", "-map", "[v]", "-map", "0:a", "-c:v", "libx264", "-preset", "ultrafast", "-r", outputFPS, outputPath}


  



  47/80/2 is calculated by getting a device's screen dimensions - 1128 x 1920.

  



  When running this on certain devices, it results in an unplayable video.

  



  But running the following command works perfectly fine :

  



  "-i", mFilePath, "-crf", "18", "-c:v", "libx264", "-preset", "ultrafast", outputPath};


  



  I think the issue is with the filter being applied ?

  



  ---

  



  I compared running the first command on two different devices.

  



  

  • On the first device (Samsung J7 Pro), I was able to run the command successfully and play the video afterward. I tested the output on both devices and it is working.

  


  • On the second device (Sony Xperia Tablet Z), I was able to run the command successfully but could not play the video. I tested the output on both devices and it doesn't play on either. It does play on my computer.

  


  



  I compared the original video with the one not working and the one without a filter and the only difference I could find is that the one that is not working profile is Baseline@L4.2 and the one without a filter profile is Baseline@L4.0. The original video profile is High@L4.0.

  



  Here are all the videos. The original, the one without a filter (working) and the one with the filter(no working).

  



  I have no idea why this is happening ? Any help would be appreciated.

  Edit 1 :

  



  Here is the actual log as requested :

  



  "-i", "/storage/emulated/0/Android/data/com.my.package/files/CameraTemp/2020_05_24_09_17_53.mp4", "-i", "/storage/emulated/0/Android/data/com.my.package/files/MyVideos/tempShapes.png", "-filter_complex", "[0:v]scale=iw*sar:ih,setsar=1,pad='max(iw\\,2*trunc(ih*47/80/2))':'max(ih\\,2*trunc(ow*80/47/2))':(ow-iw)/2:(oh-ih)/2[v0];[1:v][v0]scale2ref[v1][v0];[v0][v1]overlay=x=(W-w)/2:y=(H-h)/2[v]", "-map", "[v]", "-map", "0:a", "-c:v", "libx264", "-preset", "ultrafast", "-r", "30", "/storage/emulated/0/Android/data/com.my.package/files/MyVideos/video with line.mp4"

  if i use this command :

  



  ffmpeg -re -threads 0 -loglevel debug -hwaccel cuvid -hwaccel_output_format cuda -i 1.mp4 -c:v h264_nvenc -c:a aac -ac 2 -b:a 128k -strict -2 -filter_complex "[0:v]scale_npp=1280:-2" ouzz2t.mp4


  



  it will very fast.

  



  but if i use this command :

  



  ffmpeg -re -threads 0 -loglevel debug -vsync 0 -hwaccel cuvid -hwaccel_output_format cuda -hwaccel_device intel -i 1.mp4 -c:v h264_nvenc -c:a aac -ac 2 -b:a 128k -strict -2 -filter_complex "[0:v]scale_npp=1280:-2:format=yuv420p[tmp],[tmp]hwdownload,format=yuv420" ouzz2t.mp4


  



  it will never finished, one 40MB mp4 will transcode 44 minutes and not finished.

  



  as you see

  it will only use GPU memory 8mib.

  



  and top will show :

  Stop at Loaded sym : cuWaitExternalSemaphoresAsync, and ffmpeg will always 100% cpu and never finished.

  



  Appeared only recently, last week it work fine, but today it work worse.

  



  somebody know what happen to me ?
