• How do I change audio language using ffmpeg in video files contaning two or more audio tracks

  19 mai 2020, par warezsoftwarez

  I am transcoding video files, that contain 2 audio tracks - Polish and English. Unfortunately my transcoder messes somehow with metadata, and at the output, when I'm checking video file using MediaInfo, i see that both audio tracks are described as English. I'd like to change description of 1st audio track to Polish, so accordingly to ffmpeg documentation :

  



  To set the language of the first audio stream:
ffmpeg -i INPUT -metadata:s:a:0 language=eng OUTPUT


  



  Unfortunately, running command :

  



  ffmpeg -i INPUTPATH -metadata:s:a:0 language=pol OUTPUTPATH


  



  to overwrite input file resulted in saving file thats size is 63KB but it is described as Polish audio (no second audio track - English somehow was deleted)

  



  When I used this command, to save output file as another file, to avoid overwriting if something misses (which is current situation), but using parameter -metadata:s:a:4 because I thought that maybe I'm reading metadata from ffmpeg incorrectly, it resulted in saving output file as 800Mb with only English (no Polish track).

  



  I don't know what should I change in this command to run as I want it to - just changing metadata of first audio track language to Polish.

  



  Here is full ffmpeg output :

  



  C:\Users\user>ffmpeg -i F:\Path\33244813_6000_1_trailer.mp4 -metadata:s:a:4 language=pol F:\Path\testtest.mp4

• Problem using FFmpeg to convert MKV with A/52 B audio (aka E-AC3) to AAC

  5 juillet 2020, par nxl4

  I've got a number of MKV files which are (per VLC) encoded with A/52 B (aka E-AC3) audio codecs. I would like to convert these to AAC, but I'm having trouble doing this with FFmpeg. The command I'm running is :

  



  ffmpeg -hwaccel auto -i original_file.mkv -y -c:v copy -c:a aac output_file.mkv


  



  The command completes without error. However, the generated file has no audio when I play it. FFmpeg's output is as follows :

  Any ideas what I'm doing wrong here ? In case it helps an ffprobe -show_streams command run on the original file shows the following :

• 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"
