kandi X-RAY | jlog Summary
JLog is short for "journaled log" and this package is really an API and implementation that is libjlog. What is libjlog? libjlog is a pure C, very simple durable message queue with multiple subscribers and publishers (both thread- and multi-process safe). The basic concept is that publishers can open a log and write messages to it while subscribers open the log and consume messages from it. "That sounds easy." libjlog abstracts away the need to perform log rotation or maintenance by publishing into fixed size log buffers and eliminating old log buffers when there are no more consumers pending.

QUESTION
I encounter a problem when I try to play a video on a web browser in a component, the file can not play at all. The file was captured on Android device using MediaRecorder and MediaProjection and tried to record screen. Here is the code how I initialize the MediaRecorder:
...ANSWER
Answered 2019-Feb-20 at 17:10If you put an 'error' handler on your HTML5 video element, you can see this file produces the following error (Chrome 71):
Error 3; details: PIPELINE_ERROR_DECODE: Failed to send audio packet for decoding: timestamp=0 duration=32000 size=2 side_data_size=0 is_key_frame=1 encrypted=0 discard_padding (us)=(0, 0)
(FYI: A similar error is discussed on github here).
2 bytes is kinda small for an audio sample. A little digging reveals that this is actually a copy of the "Audio Specific Config" for your audio track, which is strange, because that information is already present in the .mp4 headers. It's being duplicated into a sample at timestamp 0 (the first sample); I'm not sure why.
You may want to take a look at the docs for setAudioEncoder(); you have not called it, and the docs state:
If this method is not called, the output file will not contain an audio track.
Yet, your file contains an audio track. So, this may warrant a little further investigation.
EDIT
Given this new understanding of your problem, it appears that the most expedient solution is just to forcibly drop the first sample from your AAC stream. Might as well do it with your "combining" code. I would subclass the AACTrackImpl like this:

Based on other questions I believe I need a correlated sub query but I can't quite figure out the syntax. My sub selection creates multiple rows per jobnumber.

QUESTION
I checked the related questions on this error, but couldn't find the answer. I have the following code. The error is related to calling jLog method and if I take it out the error is gone, so I don't understand what is the problems - just my first experience with JNI:

Answered 2017-Aug-03 at 13:33A jclass is just another Java heap object, which means it can be moved by the garbage collector, which would make the utill_class that you saved basically a dangling pointer.
If you want a jclass that stays valid, you need to create a global reference for it:

QUESTION
I'm trying to implement a Stripe payments button into my custom Joomla 3.x component called com_swa. I'm attempting to do this via Stripe's checkout. I've been following this example from the Stripe documentation but I'm having trouble doing the POST.
Here is the code I have so far:
com_swa/views/ticketpurchase/tmpl/default.php:
...ANSWER
Answered 2017-May-30 at 13:47So I got some sleep and came back to this fresh faced and realised a few things I was doing wrong. I'll list them out here incase anyone else stumbles into the same issues.
- The form in the view didn't have the hidden inputs
optionandtask. - The function I was trying to call in the controller was private when it should of been public.
Here is what my code looks like now:
com_swa/views/ticketpurchase/tmpl/default.php:
QUESTION
I'm trying to follow the instructions on this docs page, but I seem to be missing something: https://docs.joomla.org/Supporting_SEF_URLs_in_your_component
The URI that needs to be corrected is: index.php?com_component&view=legal&page=customermasteragreement
It seems like the routing function should be simple, but the page is just displaying default instead of the sub-view.
Here's my current code:
...ANSWER
Answered 2017-Mar-02 at 12:09Unless I've completely misunderstood Joomla (I've been developing with it for four five years now), there is no "sub-view" concept implemented. Trying to use the idea is what's getting you into trouble I think.
I'm astounded that the idea of using a visual debugger is so unpopular. Get yourself something like Netbeans (there are others too), set up a local web and database server, and watch the code run. Very (well, relatively very) quickly you'll start to understand how the structure hangs together.
You may put code in your view that picks up the extra params you've set and displays or hides things accordingly, but there is no "sub-view".
