  • FFMpeg generates still video

    19 juillet 2013, par Jason Muchow

    I'm doing a simple test of ffmpeg. I'd like to use it for thumbnail generation / video grabbing for a website I'm developing. I'm currently using VLC to grab a single frame and then generate a thumbnail, but it's rather slow and a bit cumbersome.

    The problem is that the video I'm using (from my own pc) is generated by security camera software and it has an odd video format. When I open it (.bvr) in VLC, it plays very, very fast. A 10 second video goes by in about 2.5 seconds. Additionally, using a simple convert with ffmpeg "ffmpeg -i test.bvr output.avi" generates a proper-length video (10 seconds), but the video frame never changes. (It's a still image)

    Test file and test output file :

    I think this is primarily caused by the fact that the IP cameras may only generate 5-7 fps but the security software doesn't know better and writes it as if it should be 24/30 fps.

    FFMpeg Reports : [m4v @ 00000000002cec60] Estimating duration from

  • 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.
