  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • GStreamer with MPEG-TS Video4Linux ATSC/DVB Recording

    21 juin 2013, par Dustin Oprea

    I'm having an impossible time setting up a filtergraph to read from a recording that I made from my DVB video4linux device. Any help would be vastly appreciated.

    How I made the recording :

    To tune the channel :

    azap -c ~/channels.conf "Florida"

    To record the channel :

    cat /dev/dvb/adapter0/dvr0 > /tmp/test

    This is the way that recordings must be made (I can not use any GST DVB plugins to do this for me).

    I used tstools to identify that the recording is a TS stream :

    tstools/bin$ ./stream_type ~/recordings/20130129-202049
    
Reading from /home/dustin/recordings/20130129-202049
    
It appears to be Transport Stream

    ...but that there are no PAT/PMT frames :

    tstools/bin$ ./tsinfo ~/recordings/20130129-202049
    
Reading from /home/dustin/recordings/20130129-202049
    
Scanning 10000 TS packets
    

    
Found 0 PAT packets and 0 PMT packets in 10000 TS packets

    I was able to produce a single ES (elementary stream) stream, by running ts2es :

    tstools/bin$ ./ts2es -pid 97 ~/recordings/20130129-202049 ~/recordings/20130129-202049.es
    
Reading from /home/dustin/recordings/20130129-202049
    
Writing to   /home/dustin/recordings/20130129-202049.es
    
Extracting packets for PID 0061 (97)
    
!!! 4 bytes ignored at end of file - not enough to make a TS packet
    
Extracted 219258 of 248113 TS packets

    I am able to play the ES stream (even though the video is frozen on the first frame) :

    gst-launch-0.10 filesrc location=~/recordings/20130129-202049.es ! decodebin2 ! autovideosink
    
gst-launch-0.10 filesrc location=~/recordings/20130129-202049.es ! decodebin2 ! xvimagesink
    
gst-launch-0.10 playbin2 uri=file:///home/dustin/recordings/20130129-202049.es

    No matter what I do, though, I can't get the original TS file to open. However, it opens in Mplayer/FFMPEG, perfectly (but not VLC). This is the output of FFMPEG :

    ffmpeg -i 20130129-202049

    This tells us that the video stream has PID 0x61 (97).

    I have been trying for a few days, so the following are only examples of a couple of attempts. I'll provide the playbin2 example first, since I know that thousands of people will respond, insisting that I just use that. It doesn't work.

    It fails [probably] because no PID has been specified with which to find the video (the "EOS" error, I think).

    Naturally, I tried the following to start by demuxing the TS format. I believe it's the "es-pids" property that receives the PID in the absence of PMT information (which tstools said there weren't any, above), but I tried "program-number", too, just in case. gst-inspect indicates that one is hex and the other is decimal :

    gst-launch-0.10 -v filesrc location=20130129-202049 ! mpegtsdemux es-pids=0x61 ! fakesink

    I'll still get the same problem whenever I use the mpegtsdemux, even if it follows mpegpsdemux, above.

    I don't understand this, since I haven't even picked a PID yet.

    What am I doing wrong ?

  • FFMPEG - Converting any kind of file to Mp4 compatible with IOS and Flash

    5 février 2013, par arashaga

    I am struggling with FFmpeg whithing Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
    I have used the following commands so far, please note that the variables starting with " !" are placeholders and will be replaces with the proper items :

    FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile
    

    
FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfile

    The above command produce an error as :

    error executing command for rendering preset HTML5 MP4, command #1 :

    nice -n 19 /usr/bin/ffmpeg/ffmpeg -y -i '80137db8c3_1334836277_int_tr_19.mp4' -s 176x100 -b:v 500k -threads 0 -vcodec libx264 -preset slow -acodec aac -ab 128k '/converted/80137db8c3_1334836277_int_tr_19.mp4' 2>&1

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
    
Alternatively use the non experimental encoder 'libfaac'.

    Another command that I used is :

    FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
    

    
FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile

    The above command produces the file correctly however it cannot be played in flash player. One thing that I noticed is this may happen if the input file is mp4 as well. This command is executed for users uploading files, so the input file could be any format.

    Below is the information about my FFmpeg version :

  • ffmpeg : avi to mp4 (h.264/aac) - sound yes, image no

    21 février 2013, par user1711384

    working with ffmpeg at a conversion (any file to mp4 (h.264/aac)) :

    exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null && \ ", $output1);
    
var_dump($output1);
    
exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1", $output2);
    
var_dump($output2);

    With a mpeg and wmv-file its working. With 2 differenz AVIs it didnt work, logfiles from path 1 arent generated and output1 is empty, output2 of course generates an error. After removing -profile:v baseline in both commands, the videofile is successfull generates, but its not possible to play it in jwplayer (sound yes, but no image).

    This is the content of output1 :
