ffmpeg playback not working on MacOS #40

Closed PePeHa closed 7 years ago

PePeHa commented 7 years ago

i installed from your mac .dmg image, latest version 0.3.6, and in node, playback seems to be working (up to 320kbps, in mp3 - 500kbps mp3 not working either by the way), but if i select ffmpeg (and yes, i have installed full package with options as you described, via brew), MKCHROMECAST is not working, regardless of settings, mp3, flac, wav, anything - just no sound at all. what could be wrong ?

PS - i am using MacOS Sierra

PePeHa commented 7 years ago

Muammar, any idea ?

Muammar, any idea ?

Can you try using the git repository with the --debug flag to see if your ffmpeg is detected, please?.

PePeHa commented 7 years ago

Hi Muammar. I installed the git, flask and everything. running in node.js it works, but again not working in ffmpeg. as per your request, i ran the following command in Terminal

python mkchromecast.py --encoder-backend ffmpeg --debug

and this was response ....

You can try the following:

  1. Uninstall soundflower.
  2. Reboot.
  3. Install soundflower. See this issue here.
  4. Try again to cast with mkchromecast.

Can you let me know if it works?.

PePeHa commented 7 years ago

dear Muammar. i re-installed Soundflower, nice clean re-install, proper removal, reboot and reinstall. however, still no sound via ffmpeg. unfortunately, i can't get it to work on MacOS Sierra, neither from Terminal nor from .dmg package.

Arrg. I have no idea at this point on what's going on in your case. When using node, you have no problem, isn't it?. Can you confirm that?.

PePeHa commented 7 years ago

thnks Muammar. dont worry about it, thnx for your help. yes, when using node.js, it works. only with ffmpeg no sound coming out at all. i was interested in ffmpeg, to stream hi-res audio to chromecast (Tidal, 44.1kHz / 88.2kHhz and 96kHz, both 16-bit as well as 24-bit, using wav or flac via ffmpeg/Soundflower)

PePeHa commented 7 years ago

PS - i would even be more than happy to pay for a working solution to get Mac Desktop audio to Chromecast Audio at high sampling-rates and bit-depth. all commercial solutions dont offer this for Mac (e.g. Airfoil only does 16-bit / 44.1kHz, as it is Airplay-protocol-based). as Tidal is now offering MQA file-streaming, there is obviously a large market for streaming un-folded MQA at 24-bit / 44.1 / 48 / 88.2 and 96 kHz to Chromecast, given Tidal only offers Chromecast support on mobile apps, and there it only goes up to 16-bit / 44.1kHz. so there is huge market for people looking to stream software-unfolded MQA from Tidal desktop App to Chromecast Audio. unfortunately there is nothing available to do this, right now.

Yes, I understand. Try the following:

  1. Start casting using ffmpeg.

  2. Open a new terminal and execute this:

ffmpeg -f avfoundation -audio_device_index  0 -i " " -f wav  output.wav
  1. Stop casting, and open output.wav. Is it recording/playing anything?.

muammar commented 7 years ago

I think in your case the command should be:

ffmpeg -f avfoundation -audio_device_index  2 -i " " -f wav  output.wav

Because we want to capture this:

[AVFoundation input device @ 0x7ff46bc00dc0] [2] Soundflower (2ch)

Try again and tell me if it records something.

PePeHa commented 7 years ago

i still get the same error - "[AVFoundation input device @ 0x7fe58fd02560] Video device not found : Input/output error"

also noticed that the device address is changing everytime i run an ffmpeg command, but maybe that's normal, i dont know

muammar commented 7 years ago

Let's do things in a cleaner way. Without casting anything (just play anything you like in your browser or media player), open the sound preferences of your macbook pro and change input and output to soundflower (2ch):

http://cdn.osxdaily.com/wp-content/uploads/2013/02/redirect-system-audio-input-from-soundflower.jpg

Then, list your devices with:

ffmpeg -f avfoundation -list_devices true -i ""

And use the index of your soundflower here:

ffmpeg -f avfoundation -audio_device_index  MY_SOUNDFLOWER_INDEX -i " " -f wav  output.wav

I am suspecting that the default device I have set in the code is not working for you. What we need is to confirm that it is the case, so then, I can implement a solution for your problem.

PePeHa commented 7 years ago

i tried, but still not working ! maybe also important to note, is that there is more than 1 device with same index !!! the Facetime camera's and (i don't know what this is, but still) Capture Screen, also have indices from 0 to 2, so maybe choosing 2 (as i did per your request), point to whatever Capture screen is, and not to Soundflower ?

Yes, I think you are correct.

Another way would be this one:

ffmpeg -f avfoundation -i ":MY_SOUNDFLOWER_INDEX " -f wav  output.wav

Note that there is an appended : that's to tell ffmpeg that we want to set the index of audio devices and nothing for the video. Hopefully that works?.

PePeHa commented 7 years ago

yes, it worked ! so what is that capture screen device that i have at same device number as soundflower, namely both on 2 ? i don't know what it is ! :-) and how do we get mkchromecast to work properly now we know this ?

muammar commented 7 years ago

Holy s***! finally. I think this is very easy to fix. The thing is that the order of your devices is different. I may just try setting the device explicitly using its name?.

Can you try this and tell me if it records something?

ffmpeg -f avfoundation -i ":Soundflower (2ch)" -f wav  output.wav
PePeHa commented 7 years ago

yes, it worked also with referring to soundflower explicitly.

muammar commented 7 years ago

yes, it worked also with referring to soundflower explicitly.

Thank you :). Hopefully this commit https://github.com/muammar/mkchromecast/commit/23fab813f0d4cecffbfac10db648505b7da945b9 solves the problem. Can you test it, please?. You need to checkout in devel and pull the changes.

PePeHa commented 7 years ago

ok, how do i install the development version of mkchromecast from terminal ?

muammar commented 7 years ago

If I remember correctly, you had installed git and you had also downloaded the git repository. So you will need to get inside the mkchromecast directory you cloned and do the following:

git pull
git fetch
git checkout devel

If you deleted the repository you cloned, you can from scratch do the following:

git clone https://github.com/muammar/mkchromecast
cd mkchromecast
git fetch
git checkout devel
PePeHa commented 7 years ago

ok, didn't delete directory :-) so did first 3 command in directory, and tried

1) python mkchromecast.py : check, worked (as previously, using node); 2) python mkchromecast.py --encoder-backend ffmpeg : still not working, unfortunately

muammar commented 7 years ago

Can you do a git log and copy/paste the first commit you see in the list, please?.

PePeHa commented 7 years ago

hmmm, yeah, your change is showing up, so git install devel went ok, see below. so there must be something else going on ...

thanks Muammar ! i had gone to sleep :-) but just tried, and it works ! great work, Muammar ! just one more thing i wondered - does mkchromecast make some cache file somewhere on disk before sending out to chromecast, and where can i find it ? also, i wondered if ffmpeg is using lossless encoding from soundflower input, so is it using libx264 and outputting into lossless wav or flac stream / file ? if there is no intermediate caching file made, how can i check the details around the encoding procedure, bit-depth, sample rates etc. from terminal ? again, thanks Muammar, this is a great project. streaming Tidal un-folded MQA from desktop to Chromecast via mkchromecast !

muammar commented 7 years ago

thanks Muammar ! i had gone to sleep :-) but just tried, and it works ! great work, Muammar !

I am glad to know it works for you now!.

just one more thing i wondered - does mkchromecast make some cache file somewhere on disk before sending out to chromecast, and where can i find it ?

No cache file here. Everything is piped to the webserver.

also, i wondered if ffmpeg is using lossless encoding from soundflower input, so is it using libx264 and outputting into lossless wav or flac stream / file ? if there is no intermediate caching file made, how can i check the details around the encoding procedure, bit-depth, sample rates etc. from terminal ? again,

What I do is to take the redirected input from soundflower (note that soundflower has a maximum of 48khz sample rate https://github.com/muammar/mkchromecast/wiki/Sample-rates). If I understand correctly soundflower maxium bit-depth is 32bits?. You can check more details in ffmpeg if you pass the --debug flag.

thanks Muammar, this is a great project. streaming Tidal un-folded MQA from desktop to Chromecast via mkchromecast !

You are welcome, and thanks for reporting and making better the app. I am interested on understanding if the bit-depth is sent as I think.

PePeHa commented 7 years ago

i don't really understand - if i go to audio/midi settings, i can choose the sample rates for SoundFlower (both input as well as output) to 44.1 / 48 / 88.2 / 96 / 176.4 and 192 kHz, always at 32-bit. so that leaves 3 questions:

1) how is it that your soundflower install only goes up to 48kHz, where mine goes up to 192kHz ?; 2) if you say, you take the redirected soundflower input, you mean no re-sampling & re-encoding is applied, you just take the raw stream and send that out to whatever one chooses, e.g. wav, flac etc. ? 3) in relation to (2), what happens specifically if Tidal sends out 88.2kHz to SoundFlower , as i can currently not choose 88.2kHz in the mkchromecast Tray - ffmpeg settings. is it re-sampled to 96kHz en re-encoded, and if so, by which method ?

lastly, i checked, launching with --debug parameter, and found something interesting (see full output below); here a summary:

PS - i checked before, using JRiver to send audio to Chromecast Audio, and maximum quality it accepts without troubles is 192kHz sampling rate at 24-bit depth, both PCM / wav as well as flac files

how is it that your soundflower install only goes up to 48kHz, where mine goes up to 192kHz ?;

I have just checked again. I read elsewhere that last year the chromecast audio was resampling everything to 48khz. Now I believe it is not the case. That's why I was just talking about 48khz. I have just checked my laptop and I have the same options as you.

if you say, you take the redirected soundflower input, you mean no re-sampling & re-encoding is applied, you just take the raw stream and send that out to whatever one chooses, e.g. wav, flac etc. ?

Yes, look at this line of code the command is taking the Soundflower input and then the resampling (or whatever is set) is done in the output part.

in relation to (2), what happens specifically if Tidal sends out 88.2kHz to SoundFlower , as i can currently not choose 88.2kHz in the mkchromecast Tray - ffmpeg settings. is it re-sampled to 96kHz en re-encoded, and if so, by which method ?

Yes, that's what would happen. In such a case, I believe I should add 88.2kHz as an option. The method is the method implemented in ffmpeg. I have no idea about those details to be honest.

lastly, i checked, launching with --debug parameter, and found something interesting (see full output below); here a summary:

output bit-depth seems to be 24-bit, which is all we need, so this seems fine;
input stream sample rate is 88.2kHz, streaming at 5644 kb/s;
output streams at only approximately half of the input bit-rate (but looking more specifically, it also mentions 128kbps and the used codec) - i also looked at Network Activity via Activity Monitor, and it show Python sending out to network effectively only approx. 300KB / second to the Chromecast Audio;

capturing soundflower & encoding and chromecasting does not seem to be lossless ! maybe mkchromecast is not choosing to use the proper encoder for lossless capture; i would really like to get lossless capture and transfer to Chromecast Audio working :-)

I think that the output of the ffmpeg has to be modified to accomplish this. If you don't mind to test the changes I can try to fix it :).

muammar commented 7 years ago

I think that WAV code is fine? Problem seems to be only with flac. I agree with you on that one.

I have modified the FLAC part to support the bitrate:

python3 mkchromecast.py --debug --encoder-backend ffmpeg -c flac -b 3000 --sample-rate 96000

Now the output looks like:

Let me know if this is ok.

Great work Muammar - both wav as well as flac encoding now streaming at full bit-rate !

PePeHa commented 7 years ago

such incredible value-for-money - streaming un-folded MQA at 24-bit / 88.2 / 96kHz with Chromecast Audio for $35 dollar in combination with mkchromecast !

muammar commented 7 years ago

@PePeHa Nice! I will close this bug report. But before doing so, do you think I should add 88.2kHz to the system tray options?

PePeHa commented 7 years ago

if it's not too much extra work for you, i would add 88.2 as well as 176.4kHz. better would even be, if mkchromecast could automatically take over the Soundflower sample rate settings. in that latter case, Tidal could exclusively force the appropriate sample rate upon Soundflower, depending on the source file (so to 44.1, 48, 88.2 or 96kHz) and mkchromecast would automatically switch its ffmpeg sample rate accordingly. at the moment, i noticed that if sample rate is changed in Soundflower after mkchromecast is launched (so mkchromecast already running), for example when changing to a track with a different sample rate, i have to re-connect Chromecast from the mkchromecast panel or otherwise there is no sound any longer. would be nice if mkchromecast could do this automatically. if it would be easy to implement, that would be a very nice feature, but if it is too complex, i can live with this limitation and am more than happy with the way it works currently !!! thanks for all this great work Muammar ! i say, Nobel Prize for Music Chromecast Audio for you !!!

That wouldn't be too much trouble to be added in the system tray.

I think that that would require more work to be done. At least detecting the sample rate from source and change ffmpeg accordingly could be more possible.

would be nice if mkchromecast could do this automatically. if it would be easy to implement, that would be a very nice feature, but if it is too complex, i can live with this limitation and am more than happy with the way it works currently !!! thanks for all this great work Muammar ! i say, Nobel Prize for Music Chromecast Audio for you !!!

Thank you for noticing all of these issues with the codecs, it makes the application better. You are more than welcome, and I LOL'ed a lot when reading about being the Nobel prize for the CC audio.

glad you LOL'd - Stockholm is waiting for you ;-)
