  BTW, after you finish the task, can we remove Python 2 supports from all
Python scripts? Or, should we keep Python 2&3 support until Mojave support
ends?

[webkit-dev] Replacing PHP with Python in Layout Tests

[Jonathan Bedard via webkit-dev]

Hello Contributors,

To help reduce the number of dependencies WebKit’s tools have, I would like to 
replace our PHP tests (and resources used by tests) with Python 3 CGI scripts. 
I’ve already attempted to convert a few dozen PHP tests and resources to 
demonstrate that this is both possible and that the resulting Python is 
comparable to the existing PHP. Additionally, as advertised in Big Sur, PHP is 
only included for compatibility with legacy software and is not recommended.

There are still a few issues to resolve (namely, an issue with Python 3 on some 
of our Windows machines), in the mean time, I want to determine if other 
platforms have any issues with replacing our PHP tests with Python 3.

Re: [webkit-dev] Webkit MediaRecorder Timeslice functionality on Safari 14.0.2 Mojave

[youenn fablet via webkit-dev]

Hi Mark,

Thanks for reaching out.

For timeslice specific questions, it might be best to continue discussions
in https://bugs.webkit.org/show_bug.cgi?id=202233.

Timeslice support in older versions of MacOS and iOS is tricky.
On those OSes, including MacOS Mojave, MediaRecorder is not enabled by
default.

On the most recent BigSur and iOS versions, MediaRecorder should be enabled
by default and timeslice should be supported.

Hope this helps,
Y

[webkit-dev] Webkit MediaRecorder Timeslice functionality on Safari 14.0.2 Mojave

[Gallery via webkit-dev]

Hi Folks

We are developing a streaming system which uses MediaRecorder with timeslice.

It's clear that Safari only has MediaRecorder as developer experiment, and that 
older versions of Safari dont support timeslice anyway.  
However, a recent WebKit thread https://bugs.webkit.org/show_bug.cgi?id=202233 

Suggests that timeslice *is* implemented in Safari 14.0.2 and the author 
provided an example jsfiddle:  https://jsfiddle.net/hdwc2xzL/ 


Our experience suggests all is not as expected:

On Big Sur (on Apple DTK)
- Safari 14.02  (with mediarecorder enabled in experimental features) does 
appear to work as expected.  MediaRecorder and timeslice all correct.


On macOS Mojave (on MacBook Pro intel)
- Safari 13 - (with mediarecorder enabled in experimental features).  
MediaRecorder initialises OK and works as expected (but without timeslice 
callbacks)
- Safari 14.0.2 (with mediarecorder enabled in experimental features)  Throws 
an error when initialising MediaRecorder "NotSupportedError: The MediaRecorder 
is unsupported on this platform”

Both our own mechanism. and the jsfiddle referenced above shows the same error;
try 
{
mediaRecorder = new MediaRecorder(window.stream, options);  // 
options is just  {videoBitsPerSecond: 150} - hence allowing default 
mimetype, window.stream successful from getUserMedia
}
catch (e) 
{
console.error('navigator.getUserMedia error:', e);
errorMsgElement.innerHTML = `navigator.getUserMedia 
error:${e.toString()}`;

// fails: "NotSupportedError: The MediaRecorder is unsupported on this platform”

 }

so we dont even get as far as calling mediaRecorder.start(timeslice_ms) any 
more (as we did with Safari 13)


Could anyone explain this behaviour in Mojave ?   
Should MediaRecorder work on the official shipping 14.02 downloaded on Mojave ?
On a related note - what should we expect from mobile Safari with respect to 
timeslice MediaRecorder ?

When might we see MediaRecorder enabled by default so we can use it for 
customer applications ???

Many Thanks !
