Audio and Video export possibilities

[richmond62]

I know that many programming languages allow one to export audio and video files
(for instance, BBC BASIC [1981] allowed one to export sound files),
something that LiveCode does not.

Is this a deficiency?

Would LiveCode benefit from these capabilities?

More dentists prefer exporting than any other option!

...oh wait, wrong commercial

I do have to admit, I've found the number of import / export file format options for vid and audio to be somewhat constrained, but not impossilbe to deal with.

Before worrying about A/V export options, I'd like to see solid cross platform A/V in LiveCode. As it stands, I have to figure out that some formats are supported by AVF/OSX and different ones by DirectShow and forget about Linux, iOS, Android, or HTML5. Trying to find the subset of formats that load and play well across erything is a nightmare. Fix this first. Even if it is just to add to the Dictionary that format X,Y, and Z are the ONLY common, compatible, formats across all platforms.

In addition to exporting, the ability to easily record audio and video should be pursued. A unified command set has been promised since early in the LC8 cycle and every time I bring it up the ETA has been pushed back.

Loooong before we expand into these more specialized activities, it would seem appropriate to first be able to simply play audio and video formats. This core functionality no longer works on Linux.

Well said, that man!

I seem to detect a common theme which I heartily agree with.

[mwieder]

Same.
And I think the import/export facility will fall out naturally when this happens.

No, certainly not.

No, certainly not.

Why to waste time of the LC team with that?
There are a lot of free online and offline converters available. For each and every platform/OS...

For example to have a *modern* libbrowser that works on all platforms is much more important.

"...would be an advantage" is a phrase more suited to political polls than to discerning priorities for engineering.

Nearly anything, even if barely useful at all, would be an "advantage", so only something obviously harmful could possibly yield a "no" majority.

Maybe more instructive would be to ask folks what feature requests or bug fixes they'd be willing to give up or postpone in order to see something else implemented.

There are many open source codecs that could work fine for this purpose:

If LiveCode choose to play only one Open Source Audio and Video
codec in all platforms, my vote is for libvpx, because libvpx
could play lossy and lossless audio and video:

I do not think that is wasting LiveCode's time at all.

Imagine, if you will, a program that teaches people foreign languages,
records their "efforts" and plays them back to them,
AND offers them the opportunity to export them so they can,
for the sake of argument, send them to an
online, human, tutor somewhere else for native-speaker validation.

Imagine, if you will, a program where end-users
can generate electronic music that can then be exported.

Now, as I have a fairly thick skin I'll choose not to take the "wasting time" comment as rude,
but merely begging the question . . .

And the question has to be:

Is Livecode "merely" a rather limited programming "thang" that offers a subset of what
other programming languages/suits/IDEs/arrangements offer, or does it have pretensions
to being much, much more than that: a full-blown programming setup?

[FourthWorld]

Isn't such specialized functionality why LCB was created, so anyone sufficiently interested in a new feature like this that depends on OS APIs could write it in a scripting language?

[richmond62]

such specialized functionality

I don't know why you rate it as specialised, or even "specialized".

An awful lot of programs "out there" import, mess around with, and export sound.
