General :: Playing Broken Video Files (Binary Split Into 6 Parts)

May 26, 2011

Today encoders are getting smarter. They can compress Blu ray similar quality in 700MB. It seems header of video file contain info about frame rate, audio/video encoder etc. which can't be guessed. In MPEG audio , every part of file is independently playable. If a movie is binary split into 6 parts & I don't have the first part then it is unplayable.

Fedora :: 12 Restored Files From USB Key - Source Files Are All Binary?

Feb 11, 2010

Before installing Fedora on my laptop I backed up my files onto a USB key. I wiped the hard disk and installed Fedora 12. I copied my files back to my home directory - but all the text files are now binary! Any ideas why this would be or how to fix it??---------- Post added at 10:54 AM CST ---------- Previous post was at 10:35 AM CST ----------Hmm it seems that only some files are binary. Looks like some .tgz files are corrupted too.---------- Post added at 11:02 AM CST ---------- Previous post was at 10:54 AM CST ----------Damn - I wonder if the files weren't completely written to the usb key before I removed it. I don't remember their being a safe mount option in Fedora 10 - but I definitely unmounted it before removing it from the laptop.

Software :: Sed Syntax For Binary Wrapped EPS Files

Oct 8, 2010

I'm having a problem with sed syntax. So far I can sed the HiResBoundingBox to capture the images I want and output to pdf. But now ever so often I get an illustrator file that has hexadecimal values at the start and end of the file. Imagemagick powers through this and still creates the rastorized previews I want but the gs dies using the epstopdf script to output the vector files. If I hand remove the hex on both ends of the file, both functions work fine and the file can still be managed in illustrator but if I resave it the hex comes back. It only happens on a few files plus it seems to serve no purpose as the files work perfectly without it. I cannot get the sed statement to work. I've tried a blue million variations with no luck. Copied some that I found, same result.

Start of bad eps file:
ADOƆ ^@^@^@5O
^@im^K^@yy^@^@%!PS-Adobe-3.1 EPSF-3.0^M

The way I need it to look:
%!PS-Adobe-3.1 EPSF-3.0^M
End of file the same:
@ @
just needs to be:
sed -n '/%/,$p' < = blank file
sed -i 's/%/,$!d/g' = same
sed 's/%/,$!d/g' = same
sed 's/%/,$!d' = same

I can't seem to find any proper reference to this.

Programming :: Patch Binary Files From Different Library?

Jul 2, 2010

I am currently implementing an upgrade system for silent upgrades in my application. I am stuck. I need the code to patch binary files. But I can't find a good third party library. My code is in C# so I would prefer a C# library, but right now I would even go as far as using a library in another language and bind it into my C# code. But I just can't find a good patch/diff library. I must be missing something. Surely there must be some libraries out there that give us the ability to patch binary files?

General :: I2C Communication From Kernel Space?

May 11, 2011

How do you interface with the Linux I2C driver from kernel space? For example, if I had LEDs connected to a GPIO expander on the I2C bus, how would I blink them twice before going down for reset from machine_reset()?

Essentially, I believe I need to call the functions i2c_smbus_write_byte(), i2c_smbus_read_byte(), etc. But these functions require I2C client data that I do not understand how to supply.

General :: Signal Communication Between The Processes?

Sep 20, 2010

I am writing a code which communicates between 2 processes created by fork() statement. Parent reads a file and write the data into a shared memory and sends a signal to the child. The child then receives a signal from the parent to start reading. After finishing the read operation the child sends a signal to the parent asking it to resume its action. Some things are going wrong in my code.

1. segmentation error in memcpy() statement.
2. terminal hangs after running the code.
3. Synchronization problem between processes..

Code: #include <stdio.h>
#include <sys/types.h>
#include <wait.h>
#include <unistd.h>

General :: Bluetooth USB Dongle - Communication Setup?

Feb 24, 2010

I am very new to linux and I have been given a school project that involves getting my windows pc talking to a linux single board computer that I have. It can be found here. [URL]. I have two bluetooth usb dongles, one to plug into my pc and one to plug into my linux board, I know that both work as I have tried talking to them both using my mobile/cell phone. Also when I plug the dongle into my linux board it recognizes something has been plugged in. However I am unsure where to go from here. I have tried "searching" for the device using my windows pc, but it will only find my cell phone and not my linux board. I also tried mounting it similar to how i would mount a usb drive e.g. mount dev/sda etc. How to setup the linux board for bluetooth communications?

General :: Palm Vx & Serial Mouse Communication ?

Apr 25, 2011

When I try to Sync a Palm Vx to my PC through serial port I get a communication error message in the gadget. My PalmOS Devices application is already configured to use tty0 or tty1 in unsuccessfully trials. I have a lot of information in the addresses, agenda, notes, etc. and do not want to loose that information gathered for years, nor to return to Windows.

As a test, I used a serial mouse in the serial port and It didn't work. I verified the Bios Setup and COM 1 and COM 2 are enabled.

I also checked my system serial support with the following commands:

And messages were OK when compared with typical outputs. My machine is a Pentium 4 CPU 1.6 GHz, in a U8668 motherboard (Award Software International). I have Ubuntu 10.04 LTS with Gnome.

I am new in Linux and don't know Bash yet. I had followed indications from Internet tutorials successfully, but I don't know how to proceed in this case.
