ERROR: [] Cannot initialize audio system

[YellowjokerR]

I just installed mrv2 and the second I open it up, I get this error:

I've tried opening up movies with mrv2 and there is just a flash of program and it crashes. Any suggestions?

[ggarra13]

1) What version of Windows are you running? You need Windows 8.1 at least. 2) Can you go to the Help->About window and tell me what version of mrv2 are you running with the build date? 3) What does your Audio Setup look like and what configuration do you have? 4) A little more technical. Can you open a Windows Terminal (or cmd.exe) from the Start menu and run mrv2 command-line:

    cd "C:\Program Files\mrv2 v1.0.6\bin"
    mrv2 -log yourmovie.mov > crash.log 2>&1

 Attach crash.log here for me to debug.

[YellowjokerR]

1. Windows 10
2. mrv2 64 bits - v1.0.6 (I was using v1.0.5 earlier and it still didn't work for me)
3. I just have Realtek(R) Audio with some type of philips computer speakers plugged into my computer.
4. here is the crash log i think? crash.log

[ggarra13]

The crash log is empty saying it did not find the mrv2 command.
Make sure you cd to:

$ cd install/dir/of/mrv2/bin $ dir mrv.exe mr2.exe #OK en the right dir $ .\mrv2.exe -log > crash.log 2>&1 $ notepad crash.log

The log should have a lot of messages of mrv2's initialization.

[ggarra13]

1) Do you have the latest audio drivers for your hardware?

2) Do you have some other program running that might be using your audio device (Zoom for example) and interfering?

3) Can you run mrv2 with Administrative privileges (go to explorer, bin dir of mrv2, select the mrv2.exe and do RMB->Run as Administrator)?

[YellowjokerR]

oh, the $ signs don't seem to work in windows? But I also ran the initial command with a correct video this time, and got this message.

Yes, your mixer is failing but the RtAudio library that mrv2 uses does not report more information. First, let's try with the latest version of RtAudio. Download this beta v1.0.7 of mrv2:

.exe: https://mega.nz/file/rX4HxCjZ#YXV60VdYx7EL5MmDqNRdcC0klcstlC7xmr3F5D8wxhk

If it still fails, then let's try to check your Windows 10 settings and your Realtek audio settings. I don't have Windows 10, so I am relying on info from chatGPT, which may not be completely accurate:

1. Check Audio Settings:

Right-click on the Volume icon in the Taskbar. Select Open Volume Mixer Settings Here you can set or mute/unmute the volume for each app

2. Debug Realtek® Audio:

Go to Settings. Click System. Click Troubleshooter then Additional troubleshooter. Look for Playing Audio and run the troubleshooter4. Go to Device Manager. Expand the Sound and Video Game Controllers. Look for Audio driver that was installed. Right-click and Update

Send pictures of each step to see if there's anything that looks fishy.

If the issue persists, it might be helpful to try using a different audio device to see if the problem is specific to their current audio setup. If the problem is indeed specific to their Realtek® Audio, you might consider reaching out to Realtek or the user’s PC manufacturer for further assistance.

Sorry it's been a while. Work got packed. I tried installing the 1.08 version. Me trying to install rtAudio: Found tutorials to help, but when it comes to cmake --help, it's saying cmake is not recognized.

I even tried different audio devices.

[ggarra13]

Okay. Forget about the installation steps of mrv2 (that's not your problem). Also, forget about installing rt_audio (it comes bundled with mrv2) and what you downloaded is just the source code to it (not a DLL nor .exe).

Your problem is a Windows configuration issue. Do the following:

Verifying the Default Device:

Double-check the Selection:

In the "Select playback device" window that you found, ensure that the desired output device (e.g., Speakers (Realtek(R) Audio)) is selected (highlighted).

Set as Default (if not already): If the preferred device isn't selected, right-click on it and choose "Set as default device."

Test you get Audio output. You can use the Windows volume control (speaker icon in the taskbar). If you get audio a bell sound when you change the audio volume, it means your audio configuration is right.

Restart mrv2 and see if it works.

[ggarra13]

Please install this beta of v1.0.9. It will not fix anything, but it will provide an additional message about the error you are facing.
