• ffmpeg commands work locally but not on server using ffmpeg heroku buildpack

  26 août 2020, par Sarmad S.

  I am running the latest ffmpeg version. Commands work well locally and I am able to generate a video from images and to write text on the video and save in the desired format. However, not all commands work on server.

  


  I am using heroku as a hosting provider, and I have installed ffmpeg buidpack to be able to run ffmpeg commands.

  


  The problem is that not all commands work on server. For example when I wirte text on video, it does not allow space between -filter_complex drawtext commands and even the text. I get an error that complains about those spaces.
Even when I fix it (by removing spaces), it only generates an empty video (0 kb).

  


  Command :

  


  -filter_complex [1]drawtext=fontfile=exljbris-MuseoSansRounded-300.otf: text='here is some text': fontcolor=white: fontsize=38: box=1: boxcolor=black@0.5: boxborderw=5: x=(w-text_w)/2: y=(h-text_h)/2[v1]; [0][v1]vstack


  


  Generating a video from one image works fine on server for some reason. Not really sure what the problem is.

  


  locally i am running windows and using ffmpeg.exe to execute commands.

  


• PHP/ffmpeg (Windows 7) : - Permission Denied. Tried everything, but still doesn't work

  27 octobre 2014, par user365465

  I have a command-line PHP script that, when given the folder name as an argument when executing the script, will find all images in said folder and resize them using FFmpeg. Problem is, I always get a Permission Denied error in FFmpeg when it attempts to get at the files within the folder. This is while being on Windows 7.

  The big problem is that I’ve tried every solution that keeps popping up on the interwebs when I search for how to fix it. I’ve changed the settings in Avast !, did the attrib command (both as normal and "Run as Administrator") to unmark as read-only, took ownership of the folder both via command line and using that GUI takeown context menu thing everyone keeps throwing around (obviously before my efforts to mark everything as not-read-only), messed with permissions, everything. I keep searching and searching for a solution, but all of the sites keep throwing out the same things over and over again - things that I’ve already tried multiple times. I’m at the end of my rope here. All I want to do is resize images quickly and automatically so I can put them up on my website, yet this has been a massive headache...

  Please help me ! :(

  Update (Additional Points) :

  • The error is through FFmpeg, not PHP. FFmpeg spits out the permission denied error, the script just continues doing what it does normally (or, at least, it would if it weren’t for my die statement that kicks in in the event of FFmpeg failing).

  • FFmpeg will execute just fine if it’s run normally through the command line instead of through the script. However, this does not help the problem of me having to resize hundreds of photos by hand !

  • I’m just running this script in the normal terminal using the CLI engine. Weird use for PHP, I know, but since I already knew how to work with FFmpeg in PHP (but in Linux !) so I figured I might as well use the code as a normal, stand-alone program...

  • FFmpeg spits out the same error regardless of which PHP function is used to execute it. It happens for shell_exec, exec, passthru, and system.
