QUESTION
I´m working on websocket scripts in PHP and JS and have issue with saving a file (img)
Sending from JS:
...ANSWER
Answered 2021-Jun-25 at 07:33Most likely your data/image, is encoded in a frame as defined by RFC6455, so you are reading that frame in PHP with socket_recv. In fact all data sent from JS via websocket is allways encoded in frames.
You have to decode these frames in order to get your data back.
Have a look at https://github.com/napengam/phpWebSocketServer/blob/master/server/RFC6455.php
There you will find the decode function.
Good luck.
QUESTION
We can set password to our project:
In VBA Editor: Tools > Properties > Protection (Set pass and check "lock for viewing protection").
But there is easy way to get access to code. I don't want to describe, but its easy (with hexeditor).
Is the way to really secure my code in .dotm file (without loosing .dotm functionality as Word template)?
...ANSWER
Answered 2021-Feb-01 at 18:43There is not really a way to make VBA code secure beyond using password protection. There is an article I found in doing a Web Search on Obstrafication for VBA, but if it was me, I wouldn't do it.
I recommend that you investigate building your solution .Net and VSTO. With compiled code, you can then Obstrficate it with products like .Net Reactor.
QUESTION
I need to create some correct videos with incorrect mediainfo for testing. For example, halved bitrate or framerate, resolution 1920x1000 instead of 1920x1080. How can I edit mediainfo?
I tried:
- VLC media player - it only allows to edit "author", "year", etc.
- OpenShot Video Editor - it allows to create video with any resolution, but i can't create 1920x1080 video with mediainfo height = 1000
- ffmpeg - it allows to set mediainfo with -metadata key or from file, but it not works for resolution
- HexEditor - I tried to find "1080" in binary format and replace with "1000" but it didn't help
Are there any other options to do this?
...ANSWER
Answered 2020-May-12 at 23:34There are two types of metadata, arbitrary and non arbitrary.
Arbitrary metadata such as author, year, etc are editable because they are ignored by the decoding engine. Other metadata such as revolution or bitrate are static and defined by the media itself. These are read only and can only be changed by changing the underlying vide stream. i.e. transcoding.
If your video is h.264, you could theoretically parse the SPS, modify the the resolution (the resolution is encoded in exp-golomb in macroblocks minus padding, its not encoded as pixels). The value would be difficult to find in a hex editor because it is variable length, and not byte aligned. You can read iso 14496-10 to know more. But doing that would make the video appear corrupted and likely undecodable.
If your video is not h264, you will need to research that codec, every codec is different.

QUESTION
Am trying to Create a static method String formatSize(long sizeInBytes)
This method needs to return the most appropriate representation for the provided file size (in bytes)
to a human-readable format with at least 2 decimal places (except for bytes).
here is my code
...ANSWER
Answered 2020-Apr-21 at 05:57You're dividing by bits but your input is already in bytes, not bits. So except for the < KB calculation you're ending up with results that are all 1/8th of the expected size calculations.
Give the following code a whirl (print statements added just to sanity check the divisors):
