even after naming a recording folder it does not record

Is it only on Windows the resulting strip is cut shorter. Like this?

The fps seems to be set correct in the command line. Any ideas how to solve this?

EDIT: If it is the first part which is missing(slow start up of ffmpeg?), maybe the strip end should be aligned with the stopped playhead position instead of the start position?

Hi, I've installed the add on to Blender 3.3. I can't select my mic from the drop down in the configuration in the video editor. Please advise on what configuration I'm missing.

Thank you

In the interest of saving people from having to install ffmpeg separately, it would be good to use Blender's own ffmpeg, but that is currently not possible.

Needs doing: look up what functionality Blender offers via ffmpeg or audaspace and how that is (not?) exposed to add-ons.
Volunteers willing to investigate are welcome.

I noticed in recent Blender 2.92 that recording has "lag". Sometimes the recording only started few frames after recording already running, so the audio being cut incorrectly.

If I do multiple recording with frame running, I can also see gap.

Showstoppers:

• I'm unsure how the path to ffmpeg is detected(or how the path must be registered). Is it something like the "add to path" part here? http://blog.gregzaal.com/how-to-install-ffmpeg-on-windows/ Or should I add a path-string-entry in the add-on Preferences just for Windows?
• The sound device string parsing apparently must be different on Windows: https://trac.ffmpeg.org/wiki/DirectShow

Instead of using ffmpeg, we could use the SoundCard package. It seems to be portable and based on the portaudio library. This means that the add-on would need to be packaged with some OS-relative dependencies. Adopting this solution should make it more predictable to display and use sound devices for audio recording in Blender.

There is no priority to do this, but volunteers willing to investigate are welcome.

Great addon to assemble tutorial videos directly in blender!
I can not get audio recorded with any Sound Card in the list... not sure if it is my system's fault, though.
Any help I can get would be appreciated, thanks...

Any hints on how to get this great thing working on Windows? Or is it downright impossible?

I'm aware that this is not directly an issue of the repo, but the link you provided does link to https://blog.gregzaal.com/how-to-install-ffmpeg-on-windows/ , which then provides download links on https://ffmpeg.zeranoe.com/builds/ , which appear to be currently unreachable.

Pointing to a different guide on how to install FFMPEG on windows could be recommended.

I've been trying to make this addon to work on Blender 2.92 on Mac, but non working properly, maybe because of M1 chip?

link to ffmpeg instructions lead to a site were download links are broken

On macOS, I think ffmpeg issue still persist. Even if I install it through Python Module Manager addon, it does not seem to work.

If this add-on is included in Blender, maybe it would be a nice gesture to users to include what pullusb suggests here(manual entry of ffmpeg path & and an alert if no ffmpeg found anywhere): #3 (comment)

With Blender 2.92 official and pushtotalk addon, somewhat I cannot do the recording, as it could not seem to find soundcard or access to ffmpeg library. Maybe something need to be setup manually by user or maybe addon has bug?

Here is an AppleScript that could be used to record audio using QuickTime instead of FFmpeg.

on run argv
	
	set startStop to item 1 of argv
	
	if startStop = "start" then
		tell application "QuickTime Player"
			set newAudioRecording to new audio recording
			tell newAudioRecording
				start
			end tell
		end tell
	else
		set thePackagePath to POSIX path of "/tmp/NewAudio.qtpxcomposition/"
		tell application "QuickTime Player"
			stop document 1 -- to stop capture
			delay 1
			set thePackageFile to (thePackagePath as POSIX file)
			save document 1 in thePackageFile
			quit
		end tell
		
		set theAudio to POSIX path of thePackagePath & "Audio Recording.m4a"
	end if
end run

run with

osascript /path/to/script.scpt {start, stop}
