Playback with no audio output #192

Open MiltonKeynes opened 4 years ago

MiltonKeynes commented 4 years ago

From some time I have been unable to playback MLV's with sound. MLV App actually shows the files with the green audio track and data on it. When exporting in any of the formats and opening the file in VLC, then I can hear the audio with the video. So, again, the issue happens only when trying to playback my files in MLV App. It happened to me with both 1.8 and 1.9 versions. Here are my specs:

Windows 10 Pro (compilation 18363) IntelCore i7-6700 3.40 GHz 16,0 GB RAM

The problem is known. But until now nobody was able to evaluate, if it is a Windows, Qt or MLVApp problem. I am not able to evaluate this, because here it works fine on all computers and platforms I have around me.

Try to use static windows build (there is older QT). Someone on the forum reported to have the probs you have and this fixed his issues.

It worked for me. Thanks so much.

masc4ii commented 4 years ago

Oh really? Hm... here it works with all versions. I am searching in the dark...

bouncyball-git commented 4 years ago

Yeah... I know (for me it woks too). Only a few people complained about no audio after we released 1.9. This is Mystery for me as well.

Also stumbled upon this issue when I tried MLV App v1.14(Qt version 5.15.2) on Arch Linux(Linux 6.5.5-lqx1-1-lqx). No audio what so ever. MLV App was built via yay, and I use pipewire for audio. Everything else works just fine.

This happened to me just now today. No audio in the latest appimage, or in the version built from source. I'm using Ubuntu 22.04. Earlier today everything was working fine.

@esbante : are you in "drop frame mode" and activated "audio output" from menu? Otherwise there is no audio playback.

Yes, but should the audio output icon look like this (haven't looked at it before)? Clicking it gives a little square around it, which makes no difference, but it is hard to tell if it is on or not

Like so

esbante commented 12 months ago

I have used the mlv-app for several years, but never come across this. It happened while I was switching between my USB-C dock, so the system audio was changing betweeen that and my laptop, if that could have messed something up? Same behaviour in the appimage as in the built version.

esbante commented 12 months ago

Ok, the sound in the appimage is working as it should now, so it is just the built version, which makes more sense. Maybe I should just rebuild it and see if it starts working.

I dig into this problem and found something that might be related or not:

  1. My system has Anaconda installed. If compiled using conda-forge gcc(13.2.0) it will not have audio playback. If compiled use /usr/bin/gcc(13.2.1) it works fine.
  2. running MLV-App under sudo will not have audio playback. Both on Appimage and built version. But on built version it seems like it's require to run under sudo to install focus pixel maps, so it's needed to running sudo first to install the maps then used it to have audio playback.

I'm on Arch Linux 6.5.10-lqx1-1-lqx with pipewire. I also discovered that focus pixel maps for some reason, not working on extracted Appimage version although it shows installed. But it's not related here so I might open another issue.
