  • How to convert .m2ts .vob Video to mkv without losing quality in COLAB FFMPEG

    19 mai 2020, par Adnan Katper

    I want to convert .m2ts and vob videos to .mkv in same resolution and quality, so how to do it in COLAB ?
I used a script All in One 1.9.1 it converts successfully but output file is verly low quality and its avc codec is version 3 while i want it to be version High@L4.1.

    



    I have mounted my gdrive and will use it as source of videos.

    



    All in one 1.9.1

  • How to change ffmpeg -threads settings [migrated]

    5 août 2014, par Jacob

    Working on a tube site. I’m running videos through ffmpeg on a linux dedicated server to convert to mp4.

    The server specs :

    Architecture:          x86_64
    
CPU op-mode(s):        32-bit, 64-bit
    
Byte Order:            Little Endian
    
CPU(s):                8
    
On-line CPU(s) list:   0-7
    
Thread(s) per core:    2
    
Core(s) per socket:    4
    
Socket(s):             1
    
NUMA node(s):          1
    
Vendor ID:             GenuineIntel
    
CPU family:            6
    
Model:                 60
    
Stepping:              3
    
CPU MHz:               3491.749
    
BogoMIPS:              6983.49
    
Virtualization:        VT-x
    
L1d cache:             32K
    
L1i cache:             32K
    
L2 cache:              256K
    
L3 cache:              8192K
    
NUMA node0 CPU(s):     0-7

    Issue during testing is that even only doing 4-5 at once, the server load skyrockets to an average of around 36. This is just a single person. I imagine when it opens, many people will be uploading at once.

    It seems ffmpeg tries to use all the resources available per conversion.

    I’ve heard there’s a -threads setting you can change, but I cannot find it. I have an 8 cpu server. It’s only used for conversions, so I’ve heard the best setting would be between 2 and 4. I can test it out.

    But how do I change this setting ? Everything I see online discusses this setting, but not the steps to change it.
