• drawbox don't work on remote server and works on local

  5 décembre 2015, par efpies

  I’ve got a completely weird problem.

  I need to draw the text over the filled rectangle. The problem is that the command line command that work on my local machine don’t work on the server ! To be precise, only drawbox command don’t work.

  Here’s the command.

  ffmpeg -i shake.mp4 -vf "scale=300:150,setsar=1/1,drawbox=w=300: h=16: x=0: y=134: color=0x1a5757: t=1000000,drawtext=x=5: y=136: fontfile=Arial.ttf: text='fdsf': fontcolor=0xd44e4e"  -c:v h264 -preset medium -b:v 256k  -f mp4 shake_conv.mp4

  Clarification

  It seems, that my question is unclear. Ok, here’s clarification.

  I need to draw the text over the filled rectangle.

  It means, that, at first, I have a video. Then I would like to draw a bar at the [0 ; 134] with width 300px and height 16px, painted with #1A5757 color. And over that bar should be placed a text.

  The problem is that the command line command that work on my local machine don’t work on the server !

  It means that I have 2 environments : local machine (my Mac OS X 10.9.2 with ffmpeg 2.0.2 installed) and the server (Debian 7 with ffmpeg 1.0.8 installed. Quite old, dunno, but no errors were in this case ; can’t find any info about version dependency).

  The last part,

  the command line command that work on my local machine don’t work on the server

  To be precise, only drawbox command don’t work.

  means that the same command above draws the bar I need in my local environment but don’t draw it on the server side. The text is drawed correctly in both cases. One more time : the text is drawed, the bar isn’t drawed. That’s my problem. I need a bar over the video. And there aren’t any bars when I execute this command on server.

  Now, I hope, this is quite clear.

  Here’s the output.

• Finding audio peaks in video files

  23 octobre 2013, par Adam Langsner

  I have a bunch of video files that I want to process. I want to write a program that can find the audio peaks in each file and return the times where those peaks occurred.

  I've looked for a lot of different APIs in different languages but couldn't get any of them to work. I am partial to php and java, so if anyone knows any good audio processing libraries in those languages that would be great ! But really I don't care too much about the language. I will need to run this program on a cron.

  Also, is it possible to use system calls to ffmpeg from within a script to accomplish this ? Thanks in advance.

• Popen subprocess giving wrong ffmpeg process ID when trying to close

  28 octobre 2023, par Goku

  I'm trying to create a Video Management System application using Python and Django, that displays live camera stream and do video recording. For this, I add cameras using POST request and everything works fine.

  


  But when I am required to update a camera's details, like IP address or password, then first I delete the camera and then create a new instance with same camera name. The problem I'm facing is that the process ID of the camera (ffmpeg instance here) is not updating, e.g. if initially the process ID was 10, then it remains 10 (in terminate() function in the code) even when I re-create the camera with new details but I do get new process ID in start() function.

  


  Below is the code :

  I think I'm making a mistake when deleting the ffmpeg subprocess but can't figure out what it is. Have tried many methods to stop/kill the subprocess but I'm still facing the problem.
I believe there is a problem with the terminate_process() function.

  


  I'm deleting the object by using the del keyword, e.g. del , maybe it's keeping the object in the memory but only destroying the reference to that object.
