• NVIDIA Version Outdated Error when mine is updated

  21 février 2021, par Agent Merlot

  I'm trying to encode stuff with my NVIDIA GeForce MX150 (Driver Version : 461.09).

  


  import os
os.system(f'ffmpeg -i "Cells at Work Season 2 - Episode 07 - English Subbed.mp4" -c:a copy -c:v hevc_nvenc "07.mp4"')

  


  Whenever I'm trying to run it, I'm getting this error.

  


  [hevc_nvenc @ 0000017a8bdf7e40] Cannot load nvEncodeAPI64.dll
[hevc_nvenc @ 0000017a8bdf7e40] The minimum required Nvidia driver for nvenc is 436.15 or newer
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!

  


  What bugs me is that it says that I need 436.15 or newer, and mine is 461.09. That means it should work, right ? Can anyone help ?

  


• ffmpeg - converting one audio track of a multi-track mp4

  30 décembre 2023, par Shaun.M

  I'm having a few mp4 with two audio tracks,
an english one in aac and a french one in dts.

  


  Now I want to convert only the french dts to eac3 with a single ffmpeg command.

  


  I use

  


  ffmpeg -hide_banner -i input.mp4 ^
             -map_metadata -1 ^
             -map 0:0 -c:v copy ^
             -map 0:1 -c:a copy ^
             -map 0:2 -c:a eac3 -b:a 1536k ^
             -metadata:s:a:0 language=eng ^
             -metadata:s:a:0 title="Stereo" ^
             -metadata:s:a:1 language=fra ^
             -metadata:s:a:1 title="Stereo" ^
output.mp4


  


  This works quite nice, but it converts both audio tracks to eac3, instead of leaving the first one untouched ...
What's wrong in the command ?
