[MediaStream] RTCDtmfSender default values need to be updated.

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Kiran]

The default ToneDuration and ToneGap values are modified in the updated spec.
So these values need to be updated.

According to spec [1]

The duration parameter indicates the duration in ms to use for each character passed in the tones parameters. The duration cannot be more than 6000 ms or less than 40 ms. The default duration is 100 ms for each tone.

The interToneGap parameter indicates the gap between tones. It MUST be at least 30 ms. The default value is 70 ms.

The changes look fine, but please add a test. A new test would be fine, or you should be able to modify LayoutTests/fast/mediastream/RTCPeerConnection-dtmf.html to test the min, max, and defaults.

insertDTMF() has two optional parameters:

    [RaisesException] void insertDTMF(DOMString tones, optional long duration, optional long interToneGap);

so you can also test the tone duration and inter-tone gap maximum and minimum.

You should also test to ensure that exceptions are thrown when the limits are exceeded. Something like this should work:

            testDOMException("dtmfsender.insertDTMF('1', '20', '30')", "DOMException.SYNTAX_ERR");
            testDOMException("dtmfsender.insertDTMF('1', '7000', '30')", "DOMException.SYNTAX_ERR");

Reopened because no updated test results were landed. Please attach a patch with an updated RTCPeerConnection-dtmf-expected.txt.

Hi,
The code without this patch is also not giving the expected data,
The reason for this is 
1. There is not actual implementation for DTMFSender.
2. Mock implementation is, by default, returning null.

So, until the code is added for DTMFHandler (either mock implementation or full implementation), we can not invoke insertDTMF and can not test this feature.

I would like to add a FIXME comment in the code, if reviewer is ok for adding it instead of checking for the expected_output_file.

Why don't you open a bug about adding mock DTMFSender support and add a FIXME that references that bug. Ideally that would have been done with this patch, but that is my fault for not noticing :-)

HI,
I raised a new bug for implementing RTCDTMFSenderHandlerMock (BUG: 133298).
Since this patch is already landed (comment 11), it seems we can close this bug and track this on 133298.
