  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Two nearly identical ffmpeg commands, one works, the other freezes up

    28 septembre 2015, par dylanjha

    In both of these examples, I’m passing two inputs to ffmpeg applying a filter to the first input, and outputting it all to a .mp4.

    Example 1

    ffmpeg -y -threads 4 -ss 23.536 -t 44.854 -i .tmp/processing/vid-one.webm -ss 13.516 -t 54.874 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-23536-68390.mp4

    Example 2

    ffmpeg -y -threads 4 -ss 68.39 -t 3.646 -i .tmp/processing/vid-one.webm -ss 58.37 -t 13.666 -i .tmp/processing/vid-two.webm -filter_complex "[0]scale=320:-1,pad=2*iw:2*ih:0:120[left];[1]scale=320:-1[right];[left][right]overlay=main_w/2:120,scale=640:480" -shortest .tmp/processing/temp-68390-72036.mp4

    In the logging output I can get an idea of where it gets hung up.

    Output Example 1

    the output gets to this frame= line and it updates the output like this

  • ffmpeg command failed

    25 octobre 2015, par Asad kamran

    I am experimenting FFMPEG command to convert any video format to mp4.

    Server admin execute the below command created by me and show me the errors :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    This is error :

    [aac @ 0x2b845a0] The encoder ’aac’ is experimental but experimental
    codecs are not enabled, add ’-strict -2’ if you want to use it.

    how can i avoid this error and also experimental codec, so can any one let me know what can be best codec if i explicitly specify it.

    my ffmpeg and server are as follow :

    ffmpeg version N-75903-g14573b9 Copyright (c) 2000-2015 the FFmpeg
    developers built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)

    EDIT 1 :
    I change the command a bit and add -c:a copy to copy audio stream as it is but still no hope :

    New command :

    ffmpeg -ss 00:03:00  -i  /video/1444107854.mov -c:v libx264 -c:a copy /video/player/1444107854.mp4  -vframes 1 /video/thumb/1444107854.jpg

    After executing this i got a file of 23k size, apparently as in log it only copy audio stream and no video is added in final output.
    Its Log is as follow :

  • Manipulating one video into multi outputs with FFmpeg results in no audio in the last output

    27 octobre 2015, par my name is

    Using FFmpeg, I’m trying to do some filtering operations on one input video to scale it (out1), scale and trim it (out2).
    This is the command I’m using :

    ffmpeg -y \
    
-i "Robotica_1080.mkv" \
    
-filter_complex "[0:v]split=2[v1][v2]; \
    
[v1]scale=640:360,setpts=PTS-STARTPTS[vout1]; \
    
[v2]trim=10:15,scale=640:360,setpts=PTS-STARTPTS[vout2]; \
    
[0:a]asplit=2[a1][a2]; \
    
[a1]anull,asetpts=PTS-STARTPTS[aout1]; \
    
[a2]atrim=10:15,asetpts=PTS-STARTPTS[aout2]; \
    
[vout1][aout1]concat=n=1:v=1:a=1[out1]; \
    
[vout2][aout2]concat=n=1:v=1:a=1[out2]" \
    
-map "[out1]" "1.mp4" \
    
-map "[out2]" "2.mp4"

    1.mp4 is ok while 2.mp4 lasts 5 seconds as expected but without audio at all (the QuickTime inspector doesn’t write the audio codec)

    I tried to remove the trim/atrim filters, so the filter_complex parameter looked like this :

    -filter_complex "[0:v]split=2[v1][v2]; \
    
[v1]scale=640:360[vout1]; \
    
[v2]scale=640:360[vout2]; \
    
[0:a]asplit=2[a1][a2]; \
    
[a1]anull[aout1]; \
    
[a2]anull[aout2]; \
    
[vout1][aout1]concat=n=1:v=1:a=1[out1]; \
    
[vout2][aout2]concat=n=1:v=1:a=1[out2]" \

    but still no audio on 2.mp4

    Can anyone give me a hint ?

    —EDIT—
    This is the output from first ffmpeg command :
