Spent some time trying to format a file with roughly 5,000 hex values, however with no luck. For example
1b 00 10 50 a3 bb 0e b7 ff ff 00 00 00 00 09 00
01 02 00 01 00 85 03 0e 00 00 00 55 0e 04 66 03
2a 38 32 80 00 0e 00 2f c2
1b 00 10 50 a3 bb 0e b7 ff ff 00 00 00 00 09 00
01 02 00 01 00 85 03 2b 00 00 00 55 2b 04 58 28
2a 39 32 80 00 01 00 12 57 4d 32 34 30 20 41 43
20 56 65 72 2e 41 00 00 23 06 00 0a 23 06 00 0a
01 00 00 c0 14 56
1b 00 30 a6 59 b8 0e b7 ff ff 00 00 00 00 09 00
00 02 00 01 00 04 03 0d 00 00 00 55 0d 04 33 2a
03 3a 32 40 00 0e be 40
1b 00 f0 01 f1 b6 0e b7 ff ff 00 00 00 00 09 00
00 02 00 01 00 04 03 0e 00 00 00 55 0e 04 66 2a
00 3b 32 40 00 01 05 c9 b1
and so on..
I need to format in the following matter:
1b 00 10 50 a3 bb 0e b7 ff ff 00 00 00 00 09 00 01 02 00 01 00 85 03 0e 00 00 00 55 0e 04 66 03 2a 38 32 80 00 0e 00 2f c2
1b 00 10 50 a3 bb 0e b7 ff ff 00 00 00 00 09 00 01 02 00 01 00 85 03 2b 00 00 00 55 2b 04 58 28 2a 39 32 80 00 01 00 12 57 4d 32 34 30 20 41 43 20 56 65 72 2e 41 00 00 23 06 00 0a 23 06 00 0a 01 00 00 c0 14 56
1b 00 30 a6 59 b8 0e b7 ff ff 00 00 00 00 09 00 00 02 00 01 00 04 03 0d 00 00 00 55 0d 04 33 2a 03 3a 32 40 00 0e be 40
1b 00 f0 01 f1 b6 0e b7 ff ff 00 00 00 00 09 00 00 02 00 01 00 04 03 0e 00 00 00 55 0e 04 66 2a 00 3b 32 40 00 01 05 c9 b1
Basically put each hex block into one line still separated by space. For the life of me, i cannot figure out the regular expression to format this for me. I have tried different expressions but everything i tried either removes the line that separates hex blocks or grabs a last character of the line instead of the actual \n.
Maybe there is a better way of formatting files other than using regex
Please try regex: (?!\n\n)\n

How to get an image from this code?
I have a PCAP file having the encoded video data. I am using TCPReplay to broadcast this PCAP data to my server where I have written a QT UDP socket program to receive these packets successfully and stored their data in a QByteArray.
Here I am using PCAP file and TCPReplay as a simulator. In reality these packets will be received from another process/server.
Problem:
I would like to decode these received packets.
How can I decode these packets in C++/Qt ?
What data structure to use? Do I need to involve any FFMPEG or Gstreamer APIs?
I am completely new to video decoding so please elaborate answer with some sample code.
These are my incoming bytes:

I extracted a large number of bytes from an ISO into Notepad++ and ended up with 131,076 characters worth of space-separated values.
I would like to find where there occur at least three specific values within a fixed number of bytes of each other.
As an example, I would like the values 11, 12, and B4 to be highlighted if they are within 18 bytes (=53 characters) of each other, in this:
03 00 1F 06 01 15 12 10 00 00 00 00 00 05 00 00 00 00
04 00 3B 06 02 25 02 11 00 03 06 00 00 85 65 88 00 00
05 00 24 06 11 15 12 10 00 06 09 00 00 0C 7C 1A 00 00
06 00 41 04 12 24 01 11 00 00 00 00 00 42 00 00 00 00
07 00 26 03 11 15 12 01 00 00 00 00 00 B4 00 00 00 00
08 00 0E 06 10 15 11 11 00 08 00 00 00 CB 7C 00 00 00
09 00 0A 00 10 11 01 21 00 06 00 00 00 68 BD 00 00 00
0A 00 5B 07 10 10 20 11 00 00 00 00 00 3D 00 00 00 00
0B 00 40 00 12 24 01 12 00 00 00 00 00 00 00 00 00 00
The required result is the following, where the square brackets indicate which values need to be highlighted:
03 00 1F 06 01 15 12 10 00 00 00 00 00 05 00 00 00 00
04 00 3B 06 02 25 02 11 00 03 06 00 00 85 65 88 00 00
05 00 24 06 11 15 12 10 00 06 09 00 00 0C 7C 1A 00 00
06 00 41 04 12 24 01 11 00 00 00 00 00 42 00 00 00 00
07 00 26 03[11]15[12]01 00 00 00 00 00[B4]00 00 00 00
08 00 0E 06 10 15 11 11 00 08 00 00 00 CB 7C 00 00 00
09 00 0A 00 10 11 01 21 00 06 00 00 00 68 BD 00 00 00
0A 00 5B 07 10 10 20 11 00 00 00 00 00 3D 00 00 00 00
0B 00 40 00 12 24 01 12 00 00 00 00 00 00 00 00 00 00
Can this be done? (If not, is it possible to do so for only two values?)
Notes:
The values can appear in any order.
I don't want to clear the data around the values, just highlight them or make them stand out so that I can track and use the values to understand how a certain table works within an ISO.
The above example contains line-feeds/carriage returns just for readability. The actual data doesn't contain any - all the values are space-separated only.

i have a file in hex looking like below
9C CB CB 8D 13 75 D2 11 91 58 00 C0 4F 79 56 A4

first sixteen bytes (9C CB CB 8D 13 75 D2 11 91 58 00 C0 4F 79 56 A4) are showing header of my file.
This will convert the hexadecimal input to characters, and print them out (though the numbers 80 and greater won't actually be ASCII, since they're outside the range defined by ASCII):
#include <algorithm>
#include <iostream>
#include <iterator>
#include <string>
int main() {
std::transform(std::istream_iterator<std::string>(std::cin),
std::istream_iterator<std::string>(),
std::ostream_iterator<char>(std::cout),
[](std::string const &in) {
return (char) strtol(in.c_str(), NULL, 16);
});
}
I'm not sure how much good that'll do for you, but it seems to be what you're asking, and without more information on what you really want, it's about as good as I think anybody can probably do.
I have the following entry in a Dr Watson log. What is the significance of the "ds:0023:003a3000=??" part of the entry to the right of the FAULT line?

To summarize:
You get a register dump here:
eax=00000000 ebx=00390320 ecx=0854ff48 edx=09e44bfc esi=00012ce1 edi=0854ff61
eip=00465c51 esp=0854ff30 ebp=00000000 iopl=0 nv up ei pl zr na po nc
cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000 efl=00010246
The eip indicates the instruction that failed:
FAULT ->00465c51 8a441eff mov al,[esi+ebx-0x1] ds:0023:003a3000=??
The stuff at the end is the address that failed to read, which is the "usual" data segment of 23, and address 3A3000, whcih is composed of esi and ebx minus 1: 390320+12ce1-1. To me, that looks like an index gone bad - 3a3000 would be the first address of a new "page" in memory, so that's why it's failing at that point. 77025 bytes into an array is quite a long way, but it is of course possible that it's something else that is wrong.
