Per your request: FFMPEG still not working

[JSL101]

It still comes back with "Failure to enumerate devices." I'm on v.7.7.1. I've tried reinstalling FFMPEG, adding the PATH manually, and so on.

I fed the error message to Anthropic and it told me this was the problem:

"Looking at this error, there's actually a mismatch between the error message and what FFmpeg is reporting. What's Actually Happening The error message says "No recording devices found", but FFmpeg's output shows it did find devices:

Video: "Integrated Webcam" Audio: "Microphone (Realtek Audio)"

The actual problem is at the very end: Error opening input file dummy. What Went Wrong Your program is trying to open an input file called "dummy", which doesn't exist. This suggests:

The program is using a placeholder/dummy value instead of the actual device name The device detection logic is working (FFmpeg found your webcam and microphone) But the device selection/configuration is failing - the program isn't properly using the detected device names when trying to start recording

How to Fix It The program needs to use the actual device names FFmpeg discovered, such as:

video="Integrated Webcam" for video input audio="Microphone (Realtek Audio)" for audio input

Instead of passing "dummy" as the input file, it should construct a proper FFmpeg command like: ffmpeg -f dshow -i video="Integrated Webcam":audio="Microphone (Realtek Audio)" ... Check your program's configuration - there's likely a setting where you need to specify the input device, or there's a bug in how the program is passing the detected device names to FFmpeg."

Other AIs said the same thing: the problem comes from suing the word "dummy" in the last line, instead of the actual names of the Microphone I've selected.

I'm getting the same issue, v7.7.1, windows 11. FFmpeg installed via scoop and is on the path, terminal commands work fine. Copying error below

Hey @Tamnac and @JamesTheAwesomeDude, thank you for reporting this issue!

I've identified and fixed the root causes. There were actually two problems:

1. Device parsing bug: The regex pattern wasn't matching FFmpeg's output format because it didn't account for the [dshow @ 0x...] prefix that FFmpeg adds to device listings. This caused the parser to return zero devices even though FFmpeg successfully found them.

2. DirectShow syntax issue: The recording command wasn't using the correct DirectShow parameter format. DirectShow requires audio="Device Name" where the quotes are part of the parameter syntax.

I've created PR #985 with fixes for both issues. This should resolve the "No recording devices found" error and allow Windows users to record with device names that contain spaces and special characters like "Microphone Array (2- Realtek(R) Audio)".

Thank you for providing the detailed error logs - they were essential for identifying the issue!

I hate to be the one to say this, but it's still not working. I've done everything: reinstalled FFMPEG, set the PATH, and so on, and still I get "Failed to enumerate devices". The complete error message is:

@JSL101 wait for the pr above to actually be merged and released, then we'll see

Ah, my apologies. I thought It was merged in 7.7.2. My mistake. I’ll wait patiently.

[braden-w]

Sorry guys, gonna test this later and hopefully merge in 7.7.3! I realize that the issue might not be solved, need to run my virtual machine and hopefully see if it is fixed then.
