SOX got nothing from SoundFlower
12 septembre 2016, par xiaoseFor some reason on some comps SoundFlower does not catch audio.
I.e. there are SoundFlower but when I switch input\output to the SoundFlower I cannot get any sound. I have got only not empty file without any sound.Okay, how I try to get the sound...
Just FYI :
$ system_profiler SPSoftwareDataType
Software:
System Software Overview:
System Version: OS X 10.10.5 (14F1912)
Kernel Version: Darwin 14.5.0
Boot Volume: Macintosh HD
Boot Mode: Normal
Computer Name: Craig Computer
User Name: Craig (craigm)
Secure Virtual Memory: Enabled
Time since boot: 1 day22:12Gonna check is AVFoundation works :
$ ./ffmpeg -h demuxer=avfoundation
Demuxer avfoundation [AVFoundation input device]:
AVFoundation input device AVOptions:
-list_devices <int> .D...... list available devices (from 0 to 1) (default false)

: Input/output errorOkay, we have SoundFlower in devices :
[AVFoundation input device @ 0x7fda40421000] [2] Soundflower (2ch)
Then I run AppleScript which gonna switch to the "SoundFlower (2ch)" :
enableSF("input")
enableSF("output")
Where enableSF(stdname) is :
on enableSF(stdname)
tell application "System Preferences"
-- activate
tell anchor stdname of pane "com.apple.preference.sound" to reveal
tell application "System Events"
tell application process "System Preferences"
tell tab group 1 of window 1
delay 2
set rowslist to selected of row of table 1 of scroll area 1
set counter to 0
repeat with id in rowslist
set counter to counter + 1
set rowName to (value of text field 1 of row counter of table 1 of scroll area 1)
set output to stdname & " " & rowName
set scrpt to "echo \"" & output & "\" >> ~/Desktop/ds.log"
do shell script scrpt
if (rowName is equal to "Soundflower (2ch)") then
set selected of row counter of table 1 of scroll area 1 to true
set output to "
!!! FOUND SF for " & stdname & " " & rowName
set scrpt to "echo \"" & output & "\" >> ~/Desktop/ds.log"
log output
do shell script scrpt
exit repeat
end if
end repeat
end tell
end tell
end tell
end tell
end enableSFIn result I have got this :
input Internal Microphone
input Line In
input Digi CoreAudio Device
input Soundflower (2ch)
!!! FOUND SF for input Soundflower (2ch)
output Headphones
output Digi CoreAudio Device
output Soundflower (2ch)
!!! FOUND SF for output Soundflower (2ch)It means that we switch to the SoundFlower. Actually the same can be done by hands, but the script is more reliable as for me.
Okay, next we can try to save some audio via SOX :
$ /Applications/sox-14.3.2/sox -d /Desktop/out.wav
Input File : 'default' (coreaudio)

Aborted.And, as you can see, the SOX gives me an empty file. Rather, it gives the data, but there is no sound.
This happens on all OS from 10.10 to 10.11.6. Normal output should be this type :

Looking for a general purpose way to merge audio and video file and make an output have stereo audio with FFmpeg
21 février 2020, par Pineapple JoeSo have have the following FFmpeg command
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2,apad[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y mergeab.mp4When the input files are played separately their audio is played equally through both headphones.
But after being merged the audio from the video is on the right side and the audio from the webm file is on the left side.
I see this in the output when I run the cmd
[Parsed_amerge_2 @ 0x7fa0faf01bc0] No channel layout for input 1
[Parsed_amerge_2 @ 0x7fa0faf01bc0] Input channel layouts overlap: output layout will be determined by the number of distinct input channelsHow can I adjust this so that the output file has the audio from both the inputs in equally in the left and right sides ?
Also is there a generic way to do this such that even different configurations (video has stereo and audio has mono ... or both have stereo) result in the Audio being split evenly.
I tried using the pan filter but there is something I am not understanding about how it works because either nothing happens or I flip left and right. But I am not getting even stereo.
fwiw here is the full output.
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2,apad[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y mergeab.mp4
