Its been a while since I posted here as i've moved away from VB for the last few months. Anyway, seen as the support is so good here, i'm having with ripping MP3 files out of a MP4 video using ffmpeg.
Here's my code so far, but for some reason it doesn't want to work for me
Imports System.IO
Public Class Form1
Dim process As New Process

I am using a FTP code found here on the forums (can't remember where), But i have a problem with it. When some images are uploaded they turn out weird. For example: Here But some other images turn out well.

I am working on a program that uses AES encryption to encrypt a file. I fully understand AES encryption (after lots of research) and I am able to encrypt a big long string of binary numbers. How do you turn a file into a string of zeros and ones. Actually, a file will probably be represented using hexadecimal, so......How do you turn a file into a string of hex values? Is this even possible in vb?
View 19 RepliesI'm using FFMPEG for the first time. The upload works. The *.avi file is uploaded to the virtual path just fine. When it runs through and attempts the conversion to an FLV file, it doesn't error out - but it doesn't convert the file either. The ffmpeg.exe and pthreadGC2.dllare in the same folder ({virtual_path}uploadvideo). I do see a cmd window flash when the process starts but can make out anything displayed.
Here's my code:
File Upload
Protected Sub Submit1_ServerClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit1.ServerClick
If Not File1.PostedFile Is Nothing And File1.PostedFile.ContentLength > 0 Then
Dim GetFileName As String = File1.PostedFile.FileName
Dim fn As String = System.IO.Path.GetFileName(File1.PostedFile.FileName)

how to convert videos files using vb.net and ffmpeg. But as far as i know we cannot use multiple threads to run same exe file to convert files. Do you know how i can convert multiple videos using one external exe file (ffmpeg)?
I have not tried because my computer time was over. So iam just asking a general doubt whether if we attach it to one process then wouldn't the process get locked? Then can we multi-thread this application or not ?
I'm trying to put together a simple GUI for ffmpeg (a command-line video conversion, encoder, decoder etc..), mostly for video encoding/conversion... Now I am able to interact with ffmpeg.exe (the command line app that does all the big conversion work) with the System.Diagnostic.Process class (I know how to start the process with the arguments I need etc..) But the problem is, when I'm converting a moderately long video file it can take several minutes to complete...
[Code]...
I am making a GUI for ffmpeg. And i want a own namespace for it. So you can ex. write in Form1.vb:
ffmpeg.Execute("The command to execute")
or
ffmpeg.SetType.CBR
But i can't get it to work.This is what i have:
Imports System.IO
Namespace ffmpeg
Public Class Execute
[code]....
In the execute option, it gives me an error of Execute is a type in ffmpeg, not an expression.In the SetType thing, the two subs doesn't even come up when i call it.
I have a vb.net project which i have inserted pictures and video. I inserted a video clip using the Windows Media Player control and it does work. The issue i have is that i can't move the program to another computer because the pathname for the video will be wrong. I know i could change the pathname when i move it but this is not practical because i need to present this program. Does anybody know how to make the video accessible no matter what location the program is at?
View 6 RepliesI am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.
