Sorry, my English is not very good !

  


  I want ffmpeg to use GPU hardware acceleration. The above is my code, but it has been executing incorrectly. This problem has plagued me for several days. I hope you can help me, thank you !

  


• 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.

  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
