Media Converter And Muxer

The "Media Converter and Muxer" is an easy-to-use extension to convert media files.

Features:
1. Convert video and audio files to MP3 format
2. Extract the original audio track from a video file (Lossless conversion)
3. Merge a video and an audio file to generate a single file
4. Reduce or increase the volume of a video or audio file
5. Cut a video file into a small segment
6. Fix syncing issue between audio and video tracks by shifting them
7. Rotate a video file by 90, 180, or 270 degrees.
8. Custom conversion to most well-known formats (MP4, MPEG, 3GP, AAC, APNG, GIF) with custom input and output parameters like bit-rate and video size

Operation modes:
1. WASM mode (experimental): For conversions in this mode, there is no need for any permission. It uses the embedded FFmpeg for converting media files.
2. Native mode: You will be asked to install a minimal native client. This native client works as a bridge to the well-known FFmpeg binary. Here you can see how to install the native client for different operation systems:

2. Mac or Linux: https://www.youtube.com/watch?v=bB4Bj_APg4g
note that the video tutorial is steps for the "open-in" extension. Steps are similar for this extension as well.
