YouTube video synchronisation

[Peter Bogdanoff via use-livecode]

Hi,

Along the lines of the other conversation about sync of sound and vision:

Is there a way when I've loaded a YouTube page in the browser widget to capture 
the current time from the YouTube page video player (".html5-video-player”) as 
it plays?

This would be so fun to work on, let us know what approach you used to get
the job done. Good luck.

Re: curl in LiveCode

[matthias rebbe via use-livecode]

Hi again, 
rereading my post i noticed that the Accept...   is also a header.
So this a modified version of my sample script

-- build header

put 
"Key:e9242121ffd235b16f06c6e09cfd4373d18aa85d77dab4b858601051d4dd5b914ec298a3a29520ab"
 into pHeaders -- api key

put return & "Accept:=application/json" after pHeaders -- request JSON

-- now build url with parameters
put "https://api.abuseipdb.com/api/v2/check; into pURL

put "?ipAddress=172.217.9.174" after pURL -- add ip address

put "=90" after pUrl -- this is just to show how additional 
parameters are added to the url

put "" after pURL -- this is just to show how additional parameters are 
added to the url

-- now get the data 
put tsNetGetSync(pURL, pHeaders, rOutHeaders, rResult, rBytes) into tResult

put rOutHeaders after message -- show the received headers in message box

Re: curl in LiveCode

[matthias rebbe via use-livecode]

Hi,

i just did a short test

this works so far
put 
"Key:e9242121ffd235b16f06c6e09cfd4373d18aa85d77dab4b858601051d4dd5b914ec298a3a29520ab"
 into pHeaders
put 
tsNetGetSync("https://api.abuseipdb.com/api/v2/check?ipAddress=172.217.9.174;, 
pHeaders, rOutHeaders, rResult, rBytes) into tResult

tResult contains the same value as  the one returned executing curl via shell.

The only thing i don´t know is where and how to add the Accept:=application/json

curl in LiveCode

[Andrew Bell via use-livecode]

An API that I use was sunset on 2020-02-01 so I need to convert my  
previous stack calls from their v1 to v2 format. The original method  
was a simple url post but the updated method uses GET via curl. I was  
able to convert my calls to the new format, and can successfully get  
data when using curl through Terminal, but can't figure out how to  
properly curl in LiveCode.


There are several old posts (mailing list and forum) that explain how  
to setup httpHeaders then POST or PUT using libURL, but I can't seem  
to find a GET option. Running a shell command works, but I'd prefer a  
method that ports to mobile if possible. I tried a couple tsNet  
commands, but keep getting assorted 4xx response codes...

tsNetGet - 422
tsNetCustom - 400
tsNetPost - 405

Can anyone explain how to issue this curl command through tsNet or  
libURL and read the JSON that is returned?
curl -G --header  
"Key:e9242121ffd235b16f06c6e09cfd4373d18aa85d77dab4b858601051d4dd5b914ec298a3a29520ab" --header Accept:=application/json --data ipAddress=172.217.9.174  
https://api.abuseipdb.com/api/v2/check


That is a working API key that I'm willing to throw away now that is public.
v1 of API is @ https://www.abuseipdb.com/api
v2 of API is @ https://docs.abuseipdb.com/

Hi friends,

I am trying to print a field, but when it comes to a right aligned TAB
things go awray in the resulting PDF/printout.

LC 9.5.1, macOS 10.14.6

Please take a look here:

LC field on the right, PDF on the left.
At the bottom the TAB align and TAB stops of the field to be printed

Please note the unwanted wrapping of the first two "TOTAL für..." lines!?
But it only wraps if the text exceeds a certain length? 
No wrapping if I only supply the actual SUM in the TOTAL line. 
What am I missing?

Thanks for any hints!

Re: Synchronisation of sound and vision

[Ben Rubinstein via use-livecode]

I held off contributing to this discussion because it sounded like callbacks 
were a solid solution. However if that's not necessarily true it might be 
worth thinking about text tracks.


This depends of course on what effect you want to achieve, and what platforms 
you're targeting. But way back when (cue more CD-ROM nostalgia) we produced a 
CD-ROM including some interviews. We put the transcript in a text track in 
Quicktime, but hid the text track from the player, and intercepted it in code 
so that we could present it in the way we wanted.


I don't think LC let's you do that, but it does let you enable and disable 
tracks. So if you were happy with the default presentation of the text, that 
might be a very straightforward solution.

Tore,

I would agree if callbacks were 100% reliable. I have tried them in the past 
and found that in some cases they were missed. I never had any trouble when 
using time indices. But I should say that I haven’t needed to do this for 
several years, and the callbacks in the new player object might be completely 
reliable.

In other ways creating time indices makes your application more flexible, 
however. It’s dead simple, for instance, to set up an application where you can 
click on a line of text and play just that line. Set the startTime, set the 
endTime, set the playSelection to true, start playing. Done. That would be a 
little more challenging if all you had was callbacks.

One of the great things about LiveCode is that there is almost always more than 
one way to do what you want.

You can easily handle large audio/video files using callbacks. I would 
recommend using one file per poem though, this simplifies the handling of the 
messages sent from the player. You can basically use the same message for all 
files, resetting a counter variable each time you load a new file to handle 
with line you would like to act upon.

You could also store the callbacks for each audio file in a text file and set 
the callbacks as a part of the handler used to load each audio file.

Graham,

Take a look at the duration and the timeScale properties of player objects. By 
dividing duration by timeScale you get the length of the video in seconds.


put the duration of player  “foo” / the timescale of player  “foo” into 
totalSeconds

What you are contemplating is very doable, but you’ll have to do a fair amount 
of work to do to get the synching right. You can take one of several approaches:

- Calculate times as above to predict when to show/highlight the next line. Can 
be tricky with long video files and rounding errors.

- Check the currentTime property of the player to determine the startTime and 
endTime of each spoken line, and set the playSelection of the player to true. 
When the played segment ends, immediately load the following start and end 
times and play again. Something like this, from memory:

set the startTime of player “foo” to 444
set the endTime of player “foo” to 999
set the currentTime of player “foo” to the startTime of player “foo”
set the playerSelection of player “foo” to true
start player “foo"
- Break up the video or audio file into separate files, one line per file, then 
play each succeeding file when the previous one reaches its end. The 
playStopped message is your friend here.

Like I said, it’s doable, but takes a bit of thought and planning, creating 
segment indexes, that sort of thing.

Hope this helps.

Devin

a different length of time to recite. If it’s too much work, I guess I can just 
display the whole text and have one callback at the end of each recording. 
Maybe that is really the practical solution for a large body of work (say all 
the Shakespeare sonnets, for example).

Anyway thanks for the hint.
