Windows / MAC-OS version about bbb-recorder HOT 13 CLOSED

Hi,

If you check code here:

if(platform == "linux"){
    options.executablePath = "/usr/bin/google-chrome"
}else if(platform == "darwin"){
    options.executablePath = "/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"
}else if(platform == "win32"){
	options.executablePath = " " // here you can give full path of chrome.exe
}

Now it should work from any platform.

from bbb-recorder.

OK, in windows 64bit probably location of Google Chrome here:

C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

You can verify. So, modification will be:

if(platform == "linux"){
    options.executablePath = "/usr/bin/google-chrome"
}else if(platform == "darwin"){
    options.executablePath = "/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"
}else if(platform == "win32"){
    options.executablePath = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" // here you can give full path of chrome.exe
}

from bbb-recorder.

I've added the path as you said but with doble backslashes, made some changes related with paths:
else if(platform == "win32"){
options.executablePath = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" // here you can give full path of chrome.exe
}

from bbb-recorder.

I've started to download a recording, I saw a chrome tab with presentation on my desktop (I was expecting not see that tab, but it is okay), but when presentation ends, I got error:
ERROR: The process "18412" not found.
when I checked folders, I see that nothing recorded

I commented to skip closing process with this:
// await browser.close()
But this time downloads folder is empty, and ffmpeg gives error
stderr: downloads/Egitim-264-3509-000.webm: No such file or directory

from bbb-recorder.

Give full path of downloads directory. You are doing wrong for copyFromPath. Download directory should be user's download directory where Chrome downloaded. Sorry, don't make windows device with me.

from bbb-recorder.

Ok. somehow, I managed the filenames with absolute paths, temporarily with this:
function copyOnly(filename){
var copyFrom = "e:\Downloads\" + filename;
var copyToPath = "records";
var copyTo = copyToPath + "\" + filename;

Now, I got the web file without sounds
There is an Opus Audio track in the stream, but I don't hear sounds or speakings

from bbb-recorder.

I don't know how much you have modified the file. I think the default code should work perfectly if you just add chrome path as my example. Try to convert webm file to mp4 & see the result.

Here are my thoughts on Linux and Windows versions. Probably I will give up trying because, I see the browsers in Windows 10, unlike Linux version. I will probably not try to build a golang version because I see the browsers in Windows 10.

Linux version:
Pros:

1. Awesome
2. I don't see any browser window (maybe xvfb effect), even " headless:false,"
3. I can start three recording in separate shells with my intel E5450 quad core processor. Each processor is consumed %80 capacity. So I can download 20 presentation in a few hours.

Cons:

1. I have to start my Linux partition when booting my PC by pressing F11
2. There are hundreds of educators (M.D.s) in our medical faculty, %95 of them doesn't know what is linux, %4 of them may Install a Linux system to their computers, %1 of them may compile the code and use that program (Probably I'm the only one, between 500+ educators)

Here are my thoughts on Windows version
Pros:

1. None

Cons:

1. no sound! no sound! no sound!
   I hear no sound when watching recording in browser windows, when playing webm file, when playing converted mp4 file.
   There is an audio track coded with Opus, stereo channels, sample rate 48000 Hz, bits per sample 32, just like on Linux version.
   I checked that, there is sound if I play the presentation(s) from web.
2. I see the browser window, because "headless: false". Worse is: it starts in full window. So it is very difficult to do other things at the same time. I didn't try yet what will happen to recording quality if I exit full screen mode.
   I'm curious what will happen if I get sound? Could I start 2 or 3 recordings at the same time, without sound interference? just like on Linux? I don't know.
   Absence of xvfb for windows operating system is terrible. We may not see presentation windows in browsers.

3.  await page.close();
    await browser.close();
   

commands don't work well on Windows 10. I always got "ERROR: The process "xxxxx" not found."
So I commented browser closing. I'm closing chrome tasks from Windows Task manager manually after program finishes.
// await browser.close();

4. Even I don't use "await browser.close();" I got error below randomly when program exiting:

[Error: EPERM: operation not permitted, unlink 'C:\Users\zafer\AppData\Local\Temp\puppeteer_dev_chrome_profile-xXxXxX\CrashpadMetrics-active.pma'] {
errno: -4048,
code: 'EPERM',
syscall: 'unlink',
path: 'C:\Users\zafer\AppData\Local\Temp\puppeteer_dev_chrome_profile-xXxXxX\CrashpadMetrics-active.pma'
}

5. I tried to use chromium from https://download-chromium.appspot.com., extracted the zip file to a suitable directory with options:
   options.executablePath = "./node_modules/puppeteer/.local-chromium/win64-769697/chrome-win/chrome.exe"

Chromium browser doesn't stop at the specified time (default is 10 sn). As always, and expected from chromium, there is no sound !

from bbb-recorder.

I think your concept to use this solution isn't correct. Why are you trying to use this module from your local PC? You should use remote server to process recordings & provide processed MP4 to end users. Anyway I am closing this as it's not an issue.

I found another fork of puppetcam, which removed xvfb dependency:

I think you are misunderstanding the purpose of using xvfb. Please read more from here: https://en.wikipedia.org/wiki/Xvfb
