Read on to find out how. Embedding Zip Files Inside GIF Files Note: During tests GIF images were the only image type to give consistent results, therefore we recommend you use them as well.

When the command prompt opens you can use the cd command to change directories. All it takes to merge the files is one simple copy command, the trick is to use the /B switch like so: copy /B newfile.gif. How to Create a Secretly Disguised Folder Without Extra Software.

It is a reference on what every vi key binding does, followed by some useful vi tricks and tips. An expert will probably know most of these already, but an intermediate vi user will find valuable information, and even an expert may learn a thing or two. complete key binding reference Definitions UNBOUND - this key is not normally bound to any vi commandword - a lower-case word ("w", "b", "e" commands) is defined by a consecutive string of letters, numbers, or underscore, or a consecutive string of characters that is not any of {letters, numbers, underscore, whitespace} Word - an upper-case word ("W", "B", "E" commands) is a consecutive sequence of non-whitespace. sentenceparagraphcursor motion command - any command which positions the cursor is ok here, including the use of numeric prefixes.

Quick and simple image placeholders. A Smarter Way to Serve High-Resolution Images. Given enough time, all simple, already solved problems of the web eventually rear their ugly heads again.

A Smarter Way to Serve High-Resolution Images

Remember when limited bandwidth was a huge problem? Then bandwidth was infinite. Now it’s a problem again. And that means serving up images is once again a complex problem with no elegant solution. Its seems simple. Arguably the best solution right now is to send low-res images to every device. While that’s the safest solution for now, the web doesn’t get better if no one takes any risks. The latest image cleverness we’ve seen is Adam Bradley’s Foresight.js. Part of what makes Foresight.js appealing is its use of the proposed CSS image-set() function, one possible solution to the problem of serving up the right image at the right time. Foresight.js takes the image-set() proposal and uses an ingenious hack to make it work in other browsers: the font-family property.

Ffmpeg audio/video manipulation. How To Force File Download With PHP. HOWTO: quick reference on audio & video encoding with ffmpeg. The purpose of this article is to serve as a quick reference on how to use ffmpeg for audio and video encoding.

HOWTO: quick reference on audio & video encoding with ffmpeg

Boy can these ffmpeg flags be tricky to remember, especially codec names: they can really drive me crazy :) Let's cover audio encoding first (MPEG, MP3, AAC, 3GPP AMR, OGG, FLAC & WMA). Then, we'll talk about video (MPEG, FLV, XVID, MP4, Theora, WMV, H.264 & MKV), with a tiny bit of benchmarking as well. Finally, we'll try some heavy duty video compression for mobile devices. BTW, all these examples work (!) 1) Audio encoding. 19 ffmpeg commands for all needs. MP4Box 0.4.6 rev2735. OMA DRM. In order to encrypt a 3GP/MP4 file into a PDCF file, MP4Box uses the same process as ISMA encryption, only the drm file syntax changes.


Just like any XML file, the file must begin with the usual xml header. The file encoding SHALL BE UTF-8. The file is then a collection of OMATrack elements placed under an OMADRM document root (currently ignored). Each element describes all OMA DRM information needed to encrypt a given track. An OMATrack element may have children describing the optional textual headers defined in OMA DRM 2.0. XML Syntax Semantics trackID : specifies the track ID to encrypt. The following example shows how to encrypt a file with one track, using selective encryption of RAP samples, embedded keys and no IPMP signaling.

Node.js. Convert 3gp Using Ffmpeg? Jul 24, 2007 I'm relatively new to PHP and am creating a website which will take uploaded files and convert them to FLV files for quick viewing using an FLV player.

Convert 3gp Using Ffmpeg?

It is similar to YouTube. After a successful upload I hope to first convert the video file to FLV, and then create a thumbnail from the FLV file. In my upload script, the two commands follow eachother: exec("Video to FLV Conversion");exec("Thumbnail creation"); The video converts always, and on very small videos (below 500k) the thumbnail creation works as well... but for larger files, the thumbnail creation does not execute. My thoughts are that the Thumbnail exec() starts before the FLV Conversion exec() is completed.

Installing FFMPEG and FFMPEG-PHP on CentOS

Inorder to do this they were using ffmpeg which does all the video conversion. What FFMPEG-PHP can do and how to use the most out of it. 6.5. Encoding to MPEG format. MEncoder can create MPEG (MPEG-PS) format output files.

6.5. Encoding to MPEG format

Usually, when you are using MPEG-1 or MPEG-2 video, it is because you are encoding for a constrained format such as SVCD, VCD, or DVD. The specific requirements for these formats are explained in the VCD and DVD creation guide section. To change MEncoder's output file format, use the -of mpeg option. Example: Ffmpeg-php.
