Title: flv files have too deep sound
Post by: Barade on April 07, 2017, 09:17:27 AM
I use the Open Screen Broadcaster to record some Let's Play. I use the FLV format for the videos since when it stops (because the disk is full), the files don't get corrupted (according to some sources).

When I play the video files with the VLC player the sound is normal. When I play them in avidemux the sound is too deep.

So avidemux cannot handle the sound of FLV containers correctly?

Audio Codec information:
Type: Audi
Codec: MPEG AAC Audio (mp4a)
Channels: Stereo
Rate: 48000 Hz

I am using avidemux 2.6.15 on Fedora.

Avidemux is not a player! The sound should be handled correctly.
Test avidemux saved file in vlc, should sound similar.
Your sound settings (play device in vlc and avidemux is probably different?)

see also previous developer posting.

Check avidemux menu: Edit: Preferences: [Audio]
Local playback downmixing: [xxxxxx]
Audiodevice: [xxxxxx]

RPM Fusion could offer 2.6.19 for Fedora soon, currently it looks like the maintainer were unavailable (no reaction since March 31).

These packages are available directly via package management (dnf) with rpmfusion-free repository enabled, 2.6.16-3 is really 2.6.18.

thx for the quick answers. I am pretty sure that I had the same bug on Windows.

The audio settings on Fedora are:
Local playback downmiing: Pro Logic
AudioDevice: PulseAudioS

vlc should use pulseaudio as well. I will try the latest avidemux version.
