Timelapse Error [Errno 2] after stop recording

[mre]

Was wondering whether we should bundle ffmpeg with the app in order to avoid such scenarios. 🤔

[ItsThompson]

Make sure that you have ffmpeg installed (e.g. run brew install ffmpeg)

[ItsThompson]

Is there anyway you can check if the computer has ffmpeg already installed and if there isn't then download it?

[cmangla]

This user got a notification about ffmpeg only after "stop recording". Maybe we should warn users at startup time, just after the final print statement below:

timelapse/timelapse/__main__.py

Lines 146 to 156 in a93b77b

	def check_dependencies(self) -> None:
	try:
	subprocess.run(['ffmpeg'], check=True,
	capture_output=True, timeout=10.0)
	except subprocess.CalledProcessError:
	print("ffmpeg command was found")
	pass # ffmpeg is found, but returns non-zero exit as expected
	# This is a quick and dirty check; it leaves some spurious output
	# for the user to puzzle over.
	except OSError:
	print(not_found_msg)

[mre]

oh yeah. That print(not_found_msg) should be a notify, I guess. Wanna whip up a PR?

Yeah that would be possible. Not sure if it's a bit too invasive, though. Hm...

I remember some discussion in which we said that not_found_msg was too long for a notify, am I right?

[mre]

Heh, yeah maybe a shorter message would help.

Hi, new user here.

I'm getting the same error as @anandvip. I did the brew install ffmpeg before first-use. I also tried brew reinstall ffmpeg. No dice.

Running Catalina 10.15.4 (19E287).

[mre]

Welcome @dannyalright,
that's odd. What does ffmpeg --version give you on the commandline?

[cmangla]

@mre Perhaps we need to add shell=True to the line below in Encoder:

timelapse/timelapse/encoder.py

Lines 55 to 56 in a93b77b

	completed = subprocess.run(
	command, capture_output=True, check=True)

Just a guess.

[dnywh]

Thanks, @mre!

ffmpeg version 4.2.2 is what I get in response to ffmpeg --version.

I did, I can see the screen shots in recent files, some odd 1600 screen shots. how ever during installation ffmpeg did instruct to change the path for some of the files, which one? I don't know...

Yes, that would be great!

I have the same issue on macOS Monterey 12.4 any help would be appreciated.

ffmpeg 5.0.1_3 is already installed and up-to-date.
Python 3.10.0

[mre]

What does

which ffmpeg

say?

What does this print?

python3 -c 'import shutil; print(shutil.which("ffmpeg"))'

With the new M1 chips we'd end up bundling two versions of ffmpeg I guess: one for Intel Macs and one for arm64. :/ So I don't think we want to bundle ffmpeg after all...

Hello and thank you for your reply,
Both commands say this:
/usr/local/bin/ffmpeg
