Title: Converting DVD Dump MKV Container Using FFmpeg Command Line
In this article, we will discuss how to convert a DVD dump MKV container using the FFmpeg command line. This process involves remuxing the video and audio streams from the MKV container to maintain the original quality while changing the container format.
Prerequisites
- Install FFmpeg: Install FFmpeg on Linux
- Have a DVD dump MKV file with multiple audio streams and chapters
Step 1: Identify the Streams and Chapters
Before starting the conversion process, it's essential to identify the video and audio streams in the MKV file, as well as the chapters. You can use the following command:
ffprobe -i input.mkv -show_streams
Replace input.mkv with the name of your MKV file. This command will display information about the streams, including their index, codec type, and format.
Step 2: Select the Desired Video and Audio Streams
Choose the video and audio streams you want to keep in the new container. In this example, we will select the first video stream (video_stream_0) and the first audio stream (audio_stream_1).
Step 3: Convert the DVD Dump MKV Container
Now, we can convert the MKV container using FFmpeg. We will use the -map option to select the desired video and audio streams and the -c:v:1 and -c:a options to copy the chosen streams without re-encoding. Additionally, we will use the -sws_flags option to ensure proper resampling of the video, and the -map_chapters option to include chapters in the output file.
ffmpeg -i "input.mkv" -sws_flags spline+accurate_rnd -map 0:2 -map 0:1 -c:v:1 copy -map 0:0 -c:libopus -b:1600 output.mp4
Replace input.mkv with the name of your MKV file, and output.mp4 with the desired output file name.
Summary
- Identify the video and audio streams in the MKV file using
ffprobe - Select the desired video and audio streams
- Convert the MKV container using FFmpeg, copying the chosen streams and including chapters in the output file
