Print Multiple File Paths File Without Double Quotes and New Line Using FFmpeg
FFmpeg is a powerful tool used for handling multimedia files. It can be used to concatenate multiple video files into a single file. In this article, we will focus on how to print multiple file paths without double quotes and new lines using FFmpeg.
Key Concepts
- FFmpeg
- Concatenate video files
- Print file paths

To get started, ensure that FFmpeg is installed on your system. You can download it from the official website. Once downloaded, extract the contents and add the path to the "bin" folder to your system's PATH environment variable.
Subtitle: Concatenating Multiple Video Files
By default, FFmpeg requires input files to be specified with double quotes and new lines. However, we can modify the command to print file paths without these characters. Let's look at an example:
Example 1: Concatenating Two Video Files
To concatenate two video files, use the following command:
ffmpeg -i "input1.mp4" -i "input2.mp4" -filter_complex "[0:v][0:a] [1:v][1:a] concat=n=2:v=1:a=1 [outv] [outv][outa] concat=n=2:v=0:a=0 output.mp4" -map "[outv]" -map "[outa]"
Here, we are specifying the input files "input1.mp4" and "input2.mp4" with double quotes. To print the file paths without double quotes and new lines, we can use the following command:
ffmpeg -i input1.mp4 input2.mp4 -filter_complex "[0:v][0:a] [1:v][1:a] concat=n=2:v=1:a=1 [outv] [outv][outa] concat=n=2:v=0:a=0 output.mp4" -map "[outv]" -map "[outa]" > output.txt
The above command will concatenate the input files and save the output to "output.mp4". It will also print the input file paths to "output.txt" without double quotes and new lines.
Subtitle: Concatenating Multiple Video Files with More Than Two Files
To concatenate more than two video files, use the following command:
ffmpeg -i "input1.mp4" input2.mp4 input3.mp4 -filter_complex "[0:v][0:a] [1:v][1:a] [2:v][2:a] concat=n=3:v=1:a=1 [outv] [outv][outa] concat=n=3:v=0:a=0 output.mp4" -map "[outv]" -map "[outa]" > output.txt
Here, we are specifying the first input file "input1.mp4" with double quotes, while the subsequent files "input2.mp4" and "input3.mp4" are specified without double quotes and new lines.
In this article, we learned how to print multiple file paths without double quotes and new lines using FFmpeg while concatenating multiple video files. We used examples to illustrate the process.
