The “VLC could not open the mpga audio encoder” is an error you may encounter when trying to convert video files using the VLC media player. You may also encounter similar error with different audio or video encoder such as mp4v, mp4a, h264, hevc, mp2v, mp1v, wmv2, div3, and mjpeg. This issue is not restricted to audio files and often comes up when converting between video formats such as MKV to MP4.

In this article, we present a series of possible solutions that can help you overcome this issue. Each solution will be discussed in detail, highlighting the reasons why it might help in resolving the problem.

VLC could not open the mpga audio encoder

1. Change “Strict standard compliance” to -2

“Strict standard compliance” is a setting associated with FFmpeg, a versatile library used by VLC to handle multimedia data. This setting is designed to maintain strict compliance with multimedia standards, which, while beneficial, can occasionally lead to compatibility problems such as the “VLC could not open mpga audio encoder” issue when dealing with media files that don’t perfectly align with these standards. Adjusting this setting to “-2” relaxes the strictness, allowing VLC to process a wider variety of files.

Here’s how to modify this setting:

  1. Open VLC and navigate to “Tools” > “Preferences“.VLC Tools Preferences
  2. At the bottom of the Preferences window, change “Show settings” from “Simple” to “All“.VLC show all settings
  3. In the left pane, navigate to “Input / Codecs” > “Video codecs” > “FFmpeg“.VLC could not open the mp4a audio encoder
