• Adding Mediainfo into Videos

  13 août 2019, par yrcje

  I’m trying to add/preserve these datas while recording/editing .TS footage, (datas will be shown below), I’m using VideoReDo TVSuite5 to edit these .ts/.tp files without losing these datas, as from what I know, VideoReDo software automatically removes these miscellaneous data from the stream, I’m trying to preserve it while editing, or adding it back after editing, is there any way to do this ?

  Not much as I can’t really find any documentation on Menu info editing online. From what I can see so far, these data can only be obtained if the source itself is from a Native Internet TV Box. But is there any other way around it ?

  Menu #1
  
  ID                                       : 32 (0x20)
  
  Menu ID                                  : 2 (0x2)
  
  Duration                                 : 1 h 25 min
  
  List                                     : 33 (0x21) (MPEG Video, Korean) / 36 (0x24) (AC-3, Korean)

  The Mediainfo is inside the pastebin link.
  Mediainfo

  No error message defined a there is no known way to add these.

• FFmpeg same Filename for output but without extension with python

  10 septembre 2020, par Ptibouc77

  i'm kinda noob with Python but i managed to make this code to encode multiple videos files from a folder to H265, everything woks fine exept for the output name.

  


  Actually the output name keep the old file extension with the new one like this "MyMovie.mov.mp4" and i want it to be named like this "MyMovie.mp4" is there any way to exclude the original file extension from the output file ?

  


  import os, sys, re

input_folder= '/content/drive/My Drive/Videos'
output_folder= '/content/drive/My Drive/Videos/X265' 
quality_setting = '30'
file_type = 'mp4

my_suffixes = (".mp4", ".mov", ".mkv", ".avi", ".ts", ".flv", ".webm", ".wmv", ".mpg", ".m4v", ".f4v")

from pathlib import Path
Path(output_folder).mkdir(parents=True, exist_ok=True)

for filename in os.listdir(my_folder):
   if (filename.endswith(my_suffixes)):
       cmd = !ffmpeg -v quiet -stats -hwaccel cuvid -i "$input_folder/{filename}" -metadata comment="X265-QF$quality_setting-AAC" -c:v hevc_nvenc -preset:v slow -rc vbr -cq $quality_setting -c:a aac -b:a 160k "$output_folder/{filename}.$file_type"


  


  Ps : This code is used on Google Colab that's why i need this with python.

  


• FFMPEG : Save extracted frames to temporarily in ssd then flush to hdd

  2 février 2019, par Rishi Kataria

  I am trying to extract the frames from a video file. My HDD is slow and is acting as a bottleneck, so I wanted to save the frames to my SSD, and as it gets full, send those frames to my hard drive. so periodically flushing the frames to the hard drive. I was hoping there would be some solution for that.

  This is what I am using now :

  ffmpeg -y -hwaccel cuda -i vid.mkv %%d_frame.png

  Cheers !
