Has Anyone Ever Encountered an ".audio" File Before?

RadCazz · 11 Dec 2017

I use a program, called "getFLV" to download web videos. It works really well, but the last time I used it, I got this:

Has Anyone Ever Encountered an ".audio" File Before?-snip.jpg

In truth, I've never got the audio as a separate file before. Without the corresponding audio file, which I did find must have the same file name as the parent video, I get - you guessed it - no audio.

This kinda reminds me of subtitle files having to have the same name as the video for it to work.

Does anyone know why, perhaps, the audio downloaded as a separate file, and, is there any way to 'put back' or join the audio to make one file?

Thanks.

You can do most anything you want from a command prompt with FFmpeg.

http://ffmpeg.org/

That's an easy one I've done before....

ffmpeg -i video.mp4 -i audio.mp3 -map 0:0 -map 1:0 combined.mp4

Thank you! I downloaded the file "ffmpeg-20171211-c7a5e80-win64-static".

I will try it and tell you how it goes, following the sample you typed.

a tip - if you just type ffmpeg -i yourfile ie. you give it an input filename but not an output filename it will just tell you what video and/or audio it finds inside it. You also get a player called FFplay that uses all the same commands as FFmpeg.

You can adjust the compression vs. quality of the output video with the -crf command (Constant Rate Factor). A sensible range is 16 (virtually no compression artefacts) to 28 (about the most compression you can use before it becomes noticeable). The default is to use -crf 28 unless you specify otherwise.

Thanks again! I created a README file in my FFmpeg folder and placed your tips inside for me to follow! Tried giving rep but it says I gotta spread some around first. Oh well. I'll get back to ya!
