  • Anomalie #4109 (Fermé) : Calcul des visites d’un referer la veille en partie faux ?

    5 mars 2018, par BoOz -

    Hello,

    En regardant le code du plugins stats je vois que la première fois qu’on tombe sur un referer nouveau dans un paquet de visites récentes, on enregistre le nombre de visites pour ce referer qu’on a reçu dans ce lot de visites, et donc aussi aujourd’hui, très bien, mais aussi HIER o_O ??

    https://zone.spip.org/trac/spip-zone/browser/_core_/plugins/statistiques/genie/visites.php#L230

    Pourquoi enregistrer des visites hier si c’est la première fois qu’on voit ce referer aujourd’hui ??

    On pourrait mettre 0 pour visites_veille si ça vous va.

  • Automatic encoder selection failed for output stream #0:1

    9 juin 2018, par Rafael Lima

    I’m trying to use ffmpeg for edit some videos on android...
    It is working fine but if I try to use drawtext i get error

    the command is :

    path/ffmpeg -y -i /path/asd.mp4 -map 0 -segment_time 15 -f segment -c:v libx264 -preset veryfast -crf 30 -vf "drawtext=text='test message ':fontfile=/path/arial.ttf:box=1:boxborderw=30:boxcolor=0xE86F67@0.7:fix_bounds=true:fontcolor=0x2A363B:fontsize=32:x=0:y=h" -r 30 -force_key_frames expr:gte(t,n_forced*15) -an /path/temp%03d.mp4

    and the error is :

 Automatic encoder selection failed for output stream #0:1. Default encoder for format segment (codec none) is probably disabled. Please choose an encoder manually.
    
 Error selecting an encoder for stream 0:1

    things to considere :
    1. I’ve checked 3 times all the paths are valid
    2. I’ve tested the same command on ffmpeg 4.0 on windows and it works [with the same video]
    3. If I remove the drawtext filter it works fine...

    I tought it ffmpeg was built without drawtext or with some error so i spent 10 days in order to build it bymyself and guarantee every dependency is ok... but at end i got the same error

    does anyone have any idea please

    ==============================
    UPDATE

    I keep testing and if I remove the quotes from the filter and use a text without spacing it works

    ex :
    drawtext=text='test_message':fontfile=/path/arial.ttf:box=1:boxborderw=30:boxcolor=0xE86F67@0.7:fix_bounds=true:fontcolor=0x2A363B:fontsize=32:x=0:y=h

    so I believe there is something related to how android is escapes quotes and simple quotes because i compiled ffmpeg with same parameters and it runs on ubuntu with spaces at the text (just need to use simple quotes)

    does anyone know about it ?

  • Cortex-A7 instruction cycle timings

    15 mai 2014, par Mans — ARM

    The Cortex-A7 ARM core is a popular choice in low-power and low-cost designs. Unfortunately, the public TRM does not include instruction timing information. It does reveal that execution is in-order which makes measuring the throughput and latency for individual instructions relatively straight-forward. The table below lists the measured issue cycles … Continue reading →
