Easy methods to Convert DAV Footage to mp4 Video

With the growing recognition of laptop imaginative and prescient use instances, chances are you’ll end up leveraging present {hardware} from units like safety cameras to create laptop imaginative and prescient datasets. Common safety or CCTV techniques document in DAV versus extra standard codecs like MP4.

DAV makes use of proprietary compression to retailer video. On the time of this weblog put up, Roboflow doesn’t but help DAV add and your native machine could not actually have a DAV participant! Certainly, DAV just isn’t essentially the most intuitive format with which to work.

On this information, we’re going to present the right way to convert DAV video to mp4. With out additional ado, let’s get began!

Easy methods to Convert DAV to mp4

To transform DAV to mp4, you should utilize FFmpeg, a well-liked and complete utility for working with and changing video in numerous codecs. We’ll name an FFmpeg command in a Python script so we are able to run FFmpeg over a folder of information.

We’ll use Homebrew to put in FFmpeg on a Mac. Homebrew is a well-liked package deal supervisor for macOS. FFmpeg is an open-source, command-line device for manipulating, changing, and so forth. a variety of media codecs. For those who’re engaged on a Home windows or Linux machine, head over to FFmpeg’s website for different set up tutorials: https://ffmpeg.org/

First, open Terminal and set up Homebrew if you do not have it already. Enter the next command in Terminal and press Enter:

/bin/bash -c "$(curl -fsSL https://uncooked.githubusercontent.com/Homebrew/set up/HEAD/set up.sh)"

As soon as Homebrew is put in, enter the next command in Terminal to put in FFmpeg and press Run the next commandcomandEnter:

brew set up ffmpeg

After Set up is full, you may confirm a correct set up with the next command in terminal:

ffmpeg -version

Lastly, open up your Python program of alternative and paste the next into a brand new file:

import subprocess
def convert_dav_to_mp4(input_file, output_file): ffmpeg_command = f'ffmpeg -i "{input_file}" -c:v copy -c:a replica "{output_file}"' subprocess.name(ffmpeg_command, shell=True) # Instance utilization
input_dav_file ='/Customers/brian/Desktop/enter.dav'
output_mp4_file ='/Customers/brian/Desktop/output.mp4'
convert_dav_to_mp4(input_dav_file, output_mp4_file)

You should definitely modify the enter and output file places in traces eight and 9. On a Mac, you may double-click on the file, choose “Get data”, and replica its location right here:

Conclusion

Congratulations! You at the moment are prepared to make use of your CCTV or safety digicam footage in DAV format, convert it to MP4, and begin constructing a customized dataset in Roboflow utilizing your footage. It will allow you to start out constructing and testing laptop imaginative and prescient with probably already present {hardware}.
