Ffmpeg Improved Windows Media Browsing Tutorial<\/p><\/div>\n

Yesterday’s Ffmpeg Mux Video and Audio Windows Media Browsing Tutorial<\/a> taught us a lesson, as a side issue, that what we said when we presented Animated GIF Creation on Windows MAMP via PDF Tutorial<\/a> …<\/p>\n

\n

No matter how we tried, we could not get a Windows command line command like …<\/p>\n

\n
\nforfiles \/P \"[PathToFileBestGuess]\" \/S \/M \"[FileBaseName]\" \/C \"cmd \/c echo @path@fsize\" | find \"[FileSizeInBytes]\"
\n<\/code>
\n<\/p>\n

… to work out a file path when supplied a file base name and a file size and you call as above with starting folders. That works well (for deriverability (if that is a word!)<\/font>) in the “cmd” window but not when called under the auspices of PHP exec or shell_exec. It could be that you lose a lot of a Windows user environment when asking PHP to do some operating system work.<\/p>\n<\/blockquote>\n

… was “only partially” the story. We found out that that ” | find ” command piping could cause problems on Windows MAMP using shell_exec or exec to do some operating system functionality. But before your enthusiasm oozes over the edges, Windows “forfiles” is still very hard to get working with PHP shell_exec or exec, even using PHP to perform that ” | find ” filtering of results.<\/p>\n

However, on revisiting the issue in the changed<\/a> voiceover.php<\/a> PHP (we’d want you to download to a local MAMP<\/a> Apache web server’s Document Root folder and which you can run that PHP there<\/a>) there were dual purpose motivations going on, for us, because our changed animated GIF creator<\/a> PHP tutorial_to_animated_gif.php<\/a> (that if you download to MAMP would best go to Document Root PHP\/animegif folder along with the wonderful GIFEncoder.class.php<\/a> … thanks)<\/font> inhouse animated GIF creator web application<\/a> and the changed PDF parts to animated GIF creation helper<\/a> php_calls_pdfimages.php<\/a> (also a standalone proposition<\/a>)<\/font> PHP code could be fixed up at the same time, with a new PHP ourshell_exec<\/i> function interventional code snippet<\/font> up at the top …<\/p>\n

\n $findings=explode(\"\\n\", $nofind);

\n if (strpos(str_replace(\"\\r\",\"\",$findings[$ifindgs]), 'Directory of ') !== false) {
\n $bitbefore=explode('Directory of ', str_replace(\"\\r\",\"\",$findings[$ifindgs]))[1] . \"\\\\\";

You know it’s “Intranet feely land”?<\/p>\n

You look out the train window (tee hee)<\/font> and see macOS racing through their usual routine.<\/p>\n

Of course you’ll pick the buffet car containing the rice bubbles ahead of the vegemite corn flakes?!<\/p>\n

But do we need to reiterate that in “Intranet feely land” you’ve got your macOS typos<\/strike>e of work not suiting “arch Windows”<\/a> methodologies? Take the case of …<\/p>\n

\nAt least, with macOS MAMP there is the excellent command line “file”<\/a> we can use to show information about some potential input files you could use in this, so far, user unfriendly, “first draft” version of the PHP.\n<\/p><\/blockquote>\n

… to the beach, would be nice … but we digress. Well, in any case, we asked Google (not via the “arch Window”)<\/font> does windows have the equivalent of linux file command”<\/a> and got to the helpful What is the equivalent to the Linux File command for windows? – Super User<\/a>, thanks, and then ended up at the really useful third party “file.exe” for (non-arch)<\/font> Windows usage<\/a> and proceeded with it, working off Ffmpeg Mux Video and Audio Media Browsing Tutorial<\/a>, to start being able to develop this “reveal” details\/summary arrangement in either macOS or Windows MAMP<\/a> environments, that “ffmpeg” voiceover command, which normally works a lot better than …<\/p>\n

\nI command thee mux, hey you, with audible you, over yonder, by dale and meadow be, yea!\n<\/p><\/blockquote>\n

… when it occurred to us we could turn the base filename parts of those “file.exe<\/sub>” reports into links that when clicked mapped those clicked files into place into the “ffmpeg” command being developed above (as alternative input file designator idea to browsing or div contenteditable=true typing ways), in the changed<\/a> voiceover.php<\/a> PHP (we’d want you to download to a local MAMP<\/a> Apache web server’s Document Root folder) and which you can run that PHP there<\/a>.<\/p>\n

And so, we reckon the work day got worth it!<\/p>\n
