  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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 :

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

    12 septembre 2019, 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

  • 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
