command line closes too fast inside python using ffmpeg -

January 15, 2010

I am using Python to create macro modules inside the MaxLab environment. I wanted to use ffmpeg in the command prompt in Python The problem command prompt shut down very fast so that I can not read while executing FFPAP.

My code

  t = 'ffmpeg -r' + str (ctx.field "framerate") value) + '- f image2-pix_fmt yuv44p -s 1920x1080 - I 'path +'% 0d.png -vodec libx264 -rrf 15 '+ path +'. Mp4 'os.system (t)    
  You can file stdout / stderr and later You can try to redirect it to:  
  t = 'ffmpeg -r' + str (ctx.field ("frameRate") value) + '- f image2-pix_fmt yuv420p -s 1920x1080 -i '+ path +'% 0d.png -vcodec libx264 -crf15 '+ path +'. MP4 'log_ path = R.C: \ log.txt' OSSystem (T + '' gt; '+ log_path +' 2 & gt; and 1 ')  
  , The cause of such an issue is the lack of space between ffmpeg parameters (such as -f / -i).

sockets - capturing TCP packets flow -



    Problem statement: Suppose a parent is hosted on server machine IP: 1.1.1.1 and something in that server The time is called three different servers A (1.1.1.2), B (1.1.1.3), C (1.1.1.4). They can be server database servers or other servers. Now you can send an http request to 1.1.1.1/somepage.htm from your browser, as a result some TCP packets will go to server 1.1.1.1, and 1.1.1.1 a TCP can send packets and packets, target C as well, without installing any agent software in any server, get all TCP packet information from the browser machine. One solution is that we can write a code on server machine 1.1.1.1 which will filter all TCP packets in relation to the related IP. But I do not want that solution. Is there any way to solve this issue? Is it possible to present a new protocol for this? But server codes can not be modified.      Does any agent software include anything like Verhark? The usual way to see all the datagrams obtained is by using sniffing like a wirhark or you can ...






javascript - How to set the table width to parent div width in
wordpress widget -



    I am writing a plugin for WordPress and use a table layout in the widget wrapper to display rankings and game schedules. I am doing A line with all the information given is used in approximately 1000 pix width for a widget with a width of 260px or 360px, I want to leave less important information to display the most important information in a row. Due to interchangeable themes in WordPress, I do not know how many widgets will be in WordPress.  and examples of my current theme, based on the available width, I want to display more or fewer columns to fill the row. My idea is to first set the width of the table in the inner width of the wrapping divis, that I can do this with something like    $ ('# objects'). Width ($ ('# Object') .Parent (.) Width ()); Second, it is my goal that to display some columns per line, depending on the width of the row   My questions:    Is my planned way of accomplishing this by sending the width of the table as the parameter of the javasc...






firebird2.5 - What is the use of firebird.msg in firebird database -



    I'm thinking of using Firebird with my application. I would like to know that the  firebird.msg  is used for the file. Is it an optional or compulsory file to include in your app installer package?       firebird.msg  contains firebird's actual error messages when an error occurs , Firebird only sends the error code and message parameters. The client library then sees the actual error message text in this file.   Without the presence of this file (for firebird 2.5 and earlier its in a folder for  fbclient.dll  (or similar libraries), Firebird 3 and later the same folder In) errormessage will only report that it can not get the  firebird.msg  and error number.   So you do not really need it, but if you need firebird clients or embedded libraries or want and if you want or want a meaningful error message from the firebird, then you should include it.
