sh: 1: avconv: not found 32512

[jasonmerz]

This error code appears after line 33 in the code. I cannot figure out how to fix this or what the error means

[skiwithpete]

Exactly which script are you using? In simple or complex? Providing this help will get us deeper into it... but the solution might be fairly simple based on your subject matter...

if avconv is "not found" you might try: sudo apt-get install ffmpeg libav-tools

[jasonmerz]

I am using the simple script and I did the sudo apt_get install ffmpeg libav-tools and did not work.

[skiwithpete]

When you say it did not work, you mean that the install didn't work, or the script still doesn't work?

What happens when you just type avconv at the command prompt in terminal?

[jasonmerz]

1. Sorry for not being clear and 2. Thank you for responding and helping out.
   When I type avcov in the terminal I get: -bash: avconv: command not found
   When i type : sudo apt-get install ffmpeg libav-tools into the command line i get the below:
   Reading package lists... Done
   Building dependency tree
   Reading state information... Done
   Package libav-tools is not available, but is referred to by another package.
   This may mean that the package is missing, has been obsoleted, or
   is only available from another source
   However the following packages replace it:
   ffmpeg

E: Package 'libav-tools' has no installation candidate

[skiwithpete]

Ok, just try: sudo apt-get install ffmpeg

I did the code above and I am getting the same error in the same place

Have you done a: sudo apt-get update && sudo apt-get upgrade

Then try to reinstall:

sudo apt-get install libav-tools

[jasonmerz]

Ok, did the sudo apt-get update, the sudo apt-get upgrade and the sudo apt-get install libav-tools. I am still getting the same error on the .py file.

[skiwithpete]

Still, feels like a little progress.

What happens now when you type avconv at the command prompt in terminal?

[jasonmerz]

it says:
pi@raspberrypi:~ $ avconv
-bash: avconv: command not found

[skiwithpete]

What happens now when you type ffmpeg at the command prompt in terminal?

[jasonmerz]

Use -h to get full help or, even better, run 'man ffmpeg'

[skiwithpete]

ok, cool, we're going to need to edit that line of code then.

Line 33 should now be
system('ffmpeg -r 24 -i image%04d.jpg -vcodec libx264 -crf 20 -g 15 date +%Y%m%d%H%Mtimelapse.mp4')

[jasonmerz]

This worked great. Thanks for your help. I bought you a cup of coffee on your you tube channel. Thanks again

[skiwithpete]

Thank you, that's awesome!

As you start playing with the complex side, you'll likely find that you need to do the same updates or others. If you do, please make pull requests on the code.

I haven't used this in a while, but I intend to when I get the new camera. So keep me posted.
