• 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

• Can't Transfer .DAT (mpeg2 codec) Video to Any Other Format [closed]

  14 mai 2021, par Juan Jinping

  I have a PS2 official bonus DVD which is full of 3 hour cutscenes of MGS3. But I don't have my PS2 anymore to watch it. So I decided to transfer lossless or at least the most lossless possible. Because I am some kind of obsessed.

  


  I tried to use FFMPEG but it doesn't look it worked. At least once a minute the video goes blocky, pixelated. I tried the codes given below. I could find way more better videos on YouTube.

  


  Neither of these and their variations worked :
ffmpeg -i DEMO_3.dat DEMO_3.mkv
ffmpeg -i DEMO_3.dat -c:v libx264 -crf 0 DEMO_3.mkv

  


  I also tried it to use 3000k bitrate because it's the original bitrate of this video ffmpeg -i DEMO_3.dat -c:v libx264 -b 3000k DEMO_3.mkv

  


  Then I thought I could convert them into .png frames then reencode h264 to with "-crf 0". But frames that I extracted were blocky and pixelated too. ffmpeg -i DEMO_3.dat -r 29.970/1 %06d.png

  


  I wanted to check if my disc is broken or damaged. I downloaded the disc that I own as .iso on the internet and tried the same things but got the same results.

  


  And also the audio is not even extracted eventhough Mediainfo says there is 4 audio tracks. (probably besides English any other 3 dubs and I want them too)

  


  Long story short I want the .dat file with highest quality possible video and all audio tracks in the original mpeg2 codec or h264 codec in mkv container. You can recommend me any other program to do it or just give me code advices.

  


• How To Make Make A Video File From Images Using FFMPEG If Your Images Start At A Random Number [duplicate]

  13 mai 2019, par teot 59

  This question already has an answer here :

  • How to convert all png files from a particular number to gif using FFmpeg

  • Create video from image sequence starting at image_100
    
    1 answer
    

  So I am making a program on my raspberry pi and I am constantly saving pictures in the background and deleting them. So for instance in the images folder I have images from 123.png to 234.png

  for now I have been using this command :

  os.system("ffmpeg -f image2 -r 15 -pattern_type glob -i 'videos/*.png' -vcodec mpeg4 -y movie.avi")

  But it’s unreliable, because it mixes image numbers up

  (sorry for bad English)
