Hi Guys. Thanks for the feedback. Steve, I initially tried the following

Video1.264: Invalid data found when processing input
This is curious - it's almost as if ffmpeg doesn't recognize this as a
valid video. Can you run "file video1.264" for us? Or even better, can you
provide a small sample for us to take a look at and see for ourselves?
I tried running the video and I obtained this output. Now I ran the command
as root (sudo su).

The video has 377 MB and as I can not handle it do not know how to
edit and cut a piece for you to analyze.
"I ran the command after giving full permission to access the file.
(chmod 777 Video1.264)"
Again, your commands use sudo to run ffmpeg as root. You shouldn't have to
do this. With a 777 permission, the file is wide open for anyone. Your
restriction would then be the directory permissions.
After searching the internet, I saw a post suggesting use -f to force
ffmpeg h264 treat Video1.264 file in h264 format. As I understand the error
in the first command it was that ffmpeg could not identify the file type.
Once put -f H264 format was identified. I did not know that the h264 format
does not have audio.
Moritz, if I do not put -f H264, in the example I posted without the -f
option h264 in the end we can see that ffmpeg could not identify the file
format.
I tried to check the audio as you suggested to see the result and ffmpeg
still not identifying the file format.

Video1.264: Invalid data found when processing input
It would be really cool if I could generate the graphics, I'll keep
trying and researching.
Just a note, I am new to using ffmpeg, so I can post things that are my
interpretation of what I have read.

Probably shouldn't run ffmpeg as root, as your resulting video will be

There should _never_ be a need for this. If ffmpeg can't access a
device or file, fix that file's permissions.
What I'm guessing is that the "-f H264" is telling ffmpeg that you
want to export a .264 container format - which only contains video
No, it was given as an option _before_ "-i", so it's telling ffmpeg to
_import_ the given file as a raw H.264 stream. And that doesn't work
too well, because it can't be such a raw video if it contains audio.
As Steve suggested, just let ffmpeg detect the input itself.
To analyze the overall audio volume:
$ ffmpeg -i inputfile -vn -af volumedetect -f null -
(ffmpeg can also create graphs of the audio levels or waveforms over
time. Otherwise, you may want something like audacity.)
