  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • How to use ffmpeg / x264 2-Pass encoding for multiple bitrate output files

    2 décembre 2014, par Jonesy

    While performing a 2-Pass encode to multiple output files I was receiving the error

    ratecontrol_init: can't open stats file 1 ffmpeg2pass-2.log

    My setup is to do a single first pass and then multiple second pass encodes to output files with different target bitrates using the same first pass results.

    ffmpeg -y -i $INPUT_FILE -an -vcodec libx264 -pass 1 -b:v 700k -f rawvideo /dev/null
    

    
ffmpeg -y -i $INPUT_FILE -i out-aud.mp4 \
    
$AUDIO_OPTIONS_P2 -vcodec libx264 -pass 2 -b:v 250k -f mp4 out-250.mp4 \
    
$AUDIO_OPTIONS_P2 -vcodec libx264 -pass 2 -b:v 500k -f mp4 out-500.mp4 \
    
$AUDIO_OPTIONS_P2 -vcodec libx264 -pass 2 -b:v 700k -f mp4 out-700.mp4

    This sequence resulted in the error listed above. What I discovered thru code-inspection is that ffmpeg/x264 looks for a different set of first-pass files for each second-pass encoding path. The first encoding path uses the set of files originally created

    ffmpeg2pass-0.log
    
ffmpeg2pass-0.log.mbtree

    The second encoding path requires first-pass files with the names

    ffmpeg2pass-2.log
    
ffmpeg2pass-2.log.mbtree

    The third encoding path requires first-pass files with the names starting with ffmpeg2pass-4*, etc.

    My solution was to create soft-links to the originally created set of files with the new names that were required for each pass before running the second-pass command.

    ln -s ffmpeg2pass-0.log ffmpeg2pass-2.log
    
ln -s ffmpeg2pass-0.log.mbtree ffmpeg2pass-2.log.mbtree
    
ln -s ffmpeg2pass-0.log ffmpeg2pass-4.log
    
ln -s ffmpeg2pass-0.log.mbtree ffmpeg2pass-4.log.mbtree

    This seems to work as it results in the output encodes that I needed. However, I don’t know if this method is legitimate. Am I getting sub-optimal encoding results by using a first-pass output for one bitrate (700k) as the input to second-pass encodings for other bitrates ?

  • grabbing image frame from RTSP

    22 mars 2013, par Christopher Haag

    I have read many posts on this topic, but have yet to find a solution that works.

    I have tried VLC as well as FFMPEG to capture a frame every 10 seconds from an RTSP stream my surveillance system produces. I receive UDP timeout, trying TCP errors with FFMPEG, this is the closest I have got it to working.

    I am looking for a command which I can throw into a windows batch file which will initiate the stream, and begin dumping a file of the same name into a directory (the image must overwrite itself every 10 seconds). Any help will be very much appreciated ! Thanks !
