• 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.

  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"

  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 ?

  


• Some videos fail to chromecast with error MEDIA_UNKNOWN

  1er juin 2020, par JonasVautherin

  Using mkchromecast to cast local mp4 files, some videos work, and some don't (as in : the screen hangs on the blue chromecast logo, suggesting that the initial connection worked). I can reproduce exactly the issue described here.

  



  So I decided to go one level lower, with pychromecast, and try to see what actually happens when it hangs on the blue logo. I converted two videos to HLS format, and exposed them through an http server. The video that works with mkchromecast also works with my setup, but the one that fails, well... fails on both. With pychromecast, I don't get much more information than :

  



  


  ERROR, code 100 : MEDIA_UNKNOWN.

  


  



  From the Cast documentation, this error means :

  



  


  The media element encountered an unknown error fired from platform. The media element encountered an error that did not indicate it's one of MediaError.MEDIA_ERR_*. This should be rare.

  


  



  It is not rare for me at all, though. I thought that maybe the failing video was in an unsupported format, as described in the documentation. So I tried to compare both videos with the following command :

  



  ffprobe -v quiet -print_format json -show_streams 


  



  Video that works :

  For what I can see, the codecs are the same, and the only difference I can make is in the aspect ratio.

  



  What could be the reason for this "MEDIA_UNKNOWN" error on the chromecast side ? Is there something more I could compare between those two videos ? Could it be that the chromecast fails because of the aspect ratio ?
