QUESTION
So i am trying to record analog video from analog-video in port of the DE10-standard board.
the raw frames are 4:2:2 720x480 hence frame size should be 720*480 * 2 = 691200bytes,however i get 2 more bytes with hex value 0 at the beginning of the frametwo leading bytes.
ffmpeg complains about wrong buffer size so i removed them.
using ffmpeg -y -s 720x480 -pix_fmt yuv422p -i input_frame.yuv output_image.png
the result is way off.
analog video fed to the board has still image (photo taken by phone from TV) Reference Pic. and the result from ffmpeg is FFMPEG output.
i used HxD editor and mirrored that single frame many times to create a larger file then used the following command to encode it to MP4 file which give the same result.
ffmpeg -y -s 720x480 -pix_fmt yuv422p -i dump_video.yuv output_video.mp4.
i hope someone can help to fix the issue or point me in the right direction as i dont know if the problem is from hardware or from ffmpeg command. Thnx.

Answered 2021-May-22 at 03:58Your input won't be a planar pixel format yuv422p. It will be packed, like yuyv422,yvyu422, or uyvy422.
QUESTION
I'm currently coding in Haxe with Heaps and was checking on how to display text. One thing I want to do is give different font sizes to different texts. Naturally, I declared two Font instances and resized one of them. However, both texts are resized and I cannot manage to have them resize independently. How should I resize font sizes in Heaps?
...ANSWER
Answered 2021-Apr-27 at 09:09The approach taken does not work because DefaultFont.get() caches the result.
You could either:
- Copy the second font by doing
var font2 : h2d.Font = font.clone()so that it gets its own properties. - Adjust
scaleXandscaleYof Text.

I am trying to write a bootloader to a Virtual Floppy Drive inserted in a VirtualBox VM. Here is the following code that I have:
...ANSWER
Answered 2021-Jan-15 at 14:55You are reading from track 1 whereas the payload is on track 0. Remember: heads and tracks count from 0, sectors from 1.
Note that instead of hard-coding a disk number, you should use the number provided by the BIOS in dl.
Also note that org 0x07e0 is incorrect. The offset at which your payload is loaded is 0 in segment 0x07e0. So it should be org 0x0000 (or just no org directive at all). Given that you do not refer to any addresses in the payload, this does however not cause the problems you observe.
QUESTION
I'm trying to create a pipeline where I read from a file one bytes record at a time and send it to a `BufferBlock', which append items in the buffer block. This is linked through the trivial LinkTo () method to TransformBlock which converts each record of bytes into the MyObject object. Below is the whole method that does all this:
...ANSWER
Answered 2020-Nov-15 at 03:14You are reusing the same byte[] record over and over again, without any thread-safety considerations. No wonder that things are going south fast. If you want to ensure the correctness of the whole operation, you must use a different buffer each time:

Answered 2020-Sep-11 at 18:52In Windows PowerShell, Out-File defaults to little-endian UTF-16 encoding (colloquially known as Unicode encoding in Windows).
When you execute Out-File with the value "0", it writes the following byte sequence to the on disk file:

QUESTION
I'm using eclipse for c (Version: 2020-03 (4.15.0) Build id: 20200313-1211) and MinGW (version 0.6.3-pre-20170905-1).
I have been playing with fwrite() for the past few weeks, mainly creating BMP files, without any weird problems.
Something really strange is happening now that I do not understand at all: the resulting file has 2 extra bytes and thus the image is corrupted and can not be displayed.
- I have read the value that
fwrite()returns and is equal to the size meant to write (384 both cases) - I have checked the data of the pointer given to
fwrite()and the internal(FILE*)->_baseand both point to an address with the correct content, but different from what the generated file has.
And when deleting this 2 bytes, the image is perfectly readable (I use the software HxD).
This is the generated file, the 2 bytes are the 0D before the two 0A 00 00 00 (which are the width and height) are these extra bytes that I don't have a clue where they come from, and because where are located, they offset all the other BMP header info and corrupt the image!
Contents of the corrupted BMP file
The BMP is nothing fancy at all, just a 10x10px square with a grayscale gradient.
Thanks in advance!

Indeed was the \nconverted to \r\n issue. Creating the file as binary (fopen(<>,"wb")) has solved the issue!

QUESTION
I had to handle an exception, by catching it and matching the message and if the message contains a certain error code, do something (not relevant).
The exceptions message is this (in English, but the code and the gibberish after it is the same in any language):
...ANSWER
Answered 2020-Apr-17 at 16:20This is a common issue encountered when using bidirectional text, in other words, a text that contains both texts directionality: Right-to-Left (RTL) such as Arabic texts, and Left-to-Right (LTR).
Here we have the Arabic text mixed with English text so some rules will be applied to the text to determine the directionality. You may find details about this here.
In short, the text you see in the debugger is how the text will appear when you print it but not how it is represented in memory.
Here I use Linqpad to paste the text and the editor has immediately transformed it into the representation in memory. And once printed, the text is shown with a different directionality.
