  • Unable to install ffmpeg-php on Ubuntu 14.04

    29 septembre 2014, par Balaraman L

    I downloaded FFmpeg (version 2.2.3) and compiled with —disable-yasm and —enable-shared configuration and installed.

    I then downloaded ffmpeg-php extension from here - http://sourceforge.net/projects/ffmpeg-php/files/ffmpeg-php/0.6.0/

    I was able to phpize and configure successfully.

    phpize output :

    But, when I try to make install my ffmpeg-php extension after successfully configuring, I am getting following error.

    How can I solve this ? Or is there any other php library which can be used to extract all metadata of a video like bit rate, frame rate etc ?

  • Problems accessing codecs with ggplot and gganimate

    19 décembre 2016, par noLongerRandom

    Using gganimate. Can’t figure out how to properly access functionality of ffmpeg, specifically I want to change the codec I’m using in the video file I’m outputting.

    # load packages
    
library(ggplot)
    
library(animation)
    
library(gganimate)
    

    
# Here's my data.frame

)
    

    
#Basic plot
    
p <- ggplot(myDf, aes(x = year, y = bottom50, frame = year)) + 
    
    geom_line(color = "dodgerblue") + 
    
    geom_line(aes(y = top1), color = "darkred")

    The non-animated version gets me what I want :

    enter image description here

    And I get an animation version output to video with :

    gganimate(p, interval = .1, title_frame = FALSE, "income.mp4")

    That’s fine, but I want to change some the output parameters, specifically : alter the dimensions, the frame rate, and use a different codec.

    # change some of the options
    
ani.options(ani.height = 1080, ani.width = 1920, 
    
            interval = 0.04166667, other.opts = "-vcodec qtrle -f mov")
    
# re-animate
    
gganimate(p, title_frame = FALSE, "income.mov")

    That gives me the following error :

    Error in animation_saver(saver, filename) : 
    
  Don't know how to save animation of type mov

    I’m using ’.mov’ as my file extension because I’m trying to change to the Animation codec (so it’s no longer a .mp4 wrapper). I’ve got ffmpeg installed, so this is probably a syntax issue. But the documentation isn’t very clear here ; gganimate doesn’t have any documentation on changing codecs (or outputting any video besides an mp4), and the animation package is light on specifics as well.

  • How to convert any format to H264 (html5) video using ffmpeg ? [on hold]

    14 juillet 2013, par kheya

    I am trying to use a single command to convert avi, mov, wmv etc to H264 (HTML5 playback)
    I have command that converted the avi correctly to H264 (created .mp4 file)
    But the same command fails to convert a quicktime mov file.

    I am using the 64bit static built on windows.

    Here is the command I used to convert AVI to H264. This one works.

    for %%a in ("*.avi") do (
    
    ffmpeg -i "%%a" -c:v libx264 -preset slow -crf 20 -c:a libvo_aacenc -b:a 128k "%%~na.mp4"
    
)

    I am trying this to convert mov to H264 :

    for %%a in ("*.mov") do (
    
    ffmpeg -i "%%a" -vcodec mpeg4 -acodec libvo_aacenc "%%~na.mp4" //fails
    
    ffmpeg -i "%%a" -vcodec libx264 -vprofile high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -acodec libvo_aacenc -b:a 128k "%%~na.mp4" //fails with error )

    Appreciate if you kindly help me.

    EDIT :
    Here is the error :
    [graph 1 input from stream 0:1 @ 0000000002689260] Invalid sample format (null)
    Error opening filters !
