Description

Most sound cards support sample rates of 48 kHz and above, with bit depths often 24-bit, some even higher. Yet, when using FFmepg to capture from these devices via DirectShow (dshow) input, FFmpeg doesn't support higher than 16-bit and 44.1 kHz.

For example, here's a sound device that supports 2 channels at 96 kHz, 32-bit, but -list_devices=true says otherwise:

audio=DVS Receive  1-2 (Dante Virtual Soundcard): I/O error

This problem happens regardless of what sound device I use. I know these devices support 48 kHz, because that's the sample rate I'm currently running at. Windows also shows me in the control panel (mmsys.cpl):

https://i.imgur.com/Xeeyw9i.png

I know that these higher sample rates are supported on these devices via DirectSound because Audacity (which uses PortAudio internally) is able to record at these higher sample rates.

So, as best as I can tell, the problem lies somewhere in the FFmpeg implementation, but while skimming through the relevant code I did not see anything obvious. Anyone familiar with the details of DirectShow might have an idea?

Is not that cpl signalling WASAPI, not dshow? WASAPI input is not suported in ffmpeg, only output through SDL 2.

Replying to Balling:

Good question... I'm not sure either way.

However, I know these devices can operate at higher sample rates. For example, VLC can play 48 kHz via DirectShow. If I open a capture device and set to 48 kHz, it results in the following options:

:dshow-vdev=none :dshow-adev=DVS Receive  7-8 (Dante Virtual Soundcard)  :dshow-aspect-ratio=4\:3 :dshow-chroma= :dshow-fps=0 :no-dshow-config :no-dshow-tuner :dshow-tuner-channel=0 :dshow-tuner-frequency=0 :dshow-tuner-country=0 :dshow-tuner-standard=0 :dshow-tuner-input=0 :dshow-video-input=-1 :dshow-video-output=-1 :dshow-audio-input=-1 :dshow-audio-output=-1 :dshow-amtuner-mode=1 :dshow-audio-channels=0 :dshow-audio-samplerate=48000 :dshow-audio-bitspersample=0 :live-caching=300

We can see that the setting took effect by looking at the resulting sample rate and bitrate.

I just found out that even normal WASAPI in ffplay through SDL 2.0 is broken -- on 92000 Hz (artifacts through PCM through HDMI).

Yet it works in Potplayer. Oogh.

-ar is not option for dshow input device.

comment:6 by gacuxz, 2 years ago

Regardless using incorrect -ar option for dshow input device, problem still exists because ffmpeg still detects incorrect audio options of the sound card.

Interesting... -ar does have an effect, in that setting -ar 48000 causes the failure with the error, "Could not set audio only options". This error does not occur with -ar 44100. So, perhaps -ar is a defacto alias to -sample_rate?

In any case, I get the exact same errors/effect with -sample_rate.

You get same error because input options must be before -f dshow.

Replying to Elon Musk:

This is not correct. The options just need to be before -i.

Please see this demonstration with a 22.05 kHz sample rate, which works with either ordering:

Are you able to edit dshow device in source and recompile?

comment:13 by Brad Isbell, 2 years ago

I think I found the issue.

Poking around in the source, I found the check for stream settings and capability compatibility in dshow.c. I commented out the check for sample rate:

            if (ctx->sample_rate) {
                /*if (ctx->sample_rate > acaps->MaximumSampleFrequency ||
                    ctx->sample_rate < acaps->MinimumSampleFrequency)
                    goto next;*/
                fx->nSamplesPerSec = ctx->sample_rate;
            }

After that, I was able to set a 48 kHz sample rate and record audio, no problem.

I then enabled logging with EXTRA_CFLAGS="-DDSHOWDEBUG -DDEBUG -DTRACE" so I could look at AUDIO_STREAM_CONFIG_CAPS and the WAVEFORMATEX within the AM_MEDIA_TYPE structure. Then, running with -list_options true, we can see both structures:

...

Each iteration has the same AUDIO_STREAM_CONFIG_CAPS. However, this structure does not adequately describe the audio interface. I think the reason is that SampleFrequencyGranularity must be 11025 to describe sample rates of 44.1 kHz, 22.05 kHz, and 11.025 kHz. 48 kHz is not evenly divisible by 11,025.

We can see in AM_MEDIA_TYPE that sample rates up to 96 kHz are supported for this interface. It's just that we have to loop through and get that information.

Rather than using AUDIO_STREAM_CONFIG_CAPS, I think we should enumerate all possible AM_MEDIA_TYPE and verify that ctx is compatible afterwards.

I am not a C/C++ developer, nor familiar with the inner workings of FFmpeg, and I've never used the DirectShow APIs directly. :-) Is there anyone that could help with this refactor of dshow.c?

If it's helpful at all, here's the relevant DirectShow API documentation: https://docs.microsoft.com/en-us/previous-versions/ms784114(v=vs.85)

I think you need to check https://github.com/FFmpeg/FFmpeg/blame/master/libavdevice/dshow.c line 1005 ~ 1021 edited about 2 months ago.

Please open a new ticket. That is not THAT HARD. Mention that reverting a1c4929f65cc75b7175622a007b1e4bd37043d41 fixed your bug.

I accidentally undid part of Brad's fix in my patches. Will submit the same fix again.

yes, just that indeed. Same fix as last time (i should have used the word revert in my commit message)

i should have used the word revert 

No, revert is done by separate git command and should be clean. You should have send the patch separately, because most of the time we do not apply one patch in a patchset.

Fixed in f125c504d8fece6420bb97767f9e72414c26312a. I suppose since my tv supports 24 bit 192k I can create some virtual device and test this.
