  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Rotate mp4 videos without re-encoding

    3 novembre 2015, par stedes

    I’m looking for a way to rotate videos shot with my Nexus 4 on my Debian Wheezy sytem. The videos are shot in portrait mode and I would like to rotate them to landscape mode. Preferably the rotation is command-line driven.

    I have found several previous questions which are hinting at a good solution but I can’t seem to manage to get it working.

    To begin with there was this question :
    Rotating videos with FFmpeg

    But it indicates that ffmpeg is outdated and that I should use avconv. I found this question detailing the way to go forward.
    http://askubuntu.com/questions/269429/how-can-i-rotate-video-by-180-degrees-with-avconv

    This made me using following command :

    avconv -i original.mp4 -vf "transpose=1" -codec:v libx264 -preset slow -crf 25 -codec:a copy flipped.mp4

    However, this is painstakingly slow (last test took me more than 6 hours for less than 3 minutes of footage) and does not result in a playable movie. I also get an error in logging output which states Mb Rate > level limit.

    Is there an issue here with the re-encoding ? Should I first re-encode the videos from my phone to another, more "workable" encoding before applying the rotations ? Or am I missing another important point ?

    Thanks in advance

  • ffmpeg No NVENC capable devices found if run on multiple GPUs [duplicate]

    25 octobre 2017, par Marco Pardo

    This question is an exact duplicate of :

    i have 4 Geforce 1060 GPUs and a running ffmpeg with cuvid on ubuntu server.

    If i run this :

    /bin/ffmpeg -hwaccel cuvid -i 0.mkv -c:v hevc_nvenc -profile:v main -rc vbr_hq -qmin 18 -qmax 24 -b:v 1000k -maxrate 3000k -preset slow -rc-lookahead 32 -g 250 -c:a copy -c:s copy -map 0 -gpu 0 out0.mkv null

    (notice -gpu 0) it works like a charm. I can run 2 conversions at once (on differend GPUs) :

    /bin/ffmpeg -hwaccel cuvid -i 1.mkv -c:v hevc_nvenc -profile:v main -rc vbr_hq -qmin 18 -qmax 24 -b:v 1000k -maxrate 3000k -preset slow -rc-lookahead 32 -g 250 -c:a copy -c:s copy -map 0 -gpu 1 out1.mkv null
    
/bin/ffmpeg -hwaccel cuvid -i 2.mkv -c:v hevc_nvenc -profile:v main -rc vbr_hq -qmin 18 -qmax 24 -b:v 1000k -maxrate 3000k -preset slow -rc-lookahead 32 -g 250 -c:a copy -c:s copy -map 0 -gpu 2 out2.mkv null

    all of this works perfectly and i see via nvidia-smi that the processes use the named GPUs.

    But if i run all three commands together the first two started normal and the third creashed with :

    # [hevc_nvenc @ 0x5601103ca560] OpenEncodeSessionEx failed: out of memory (10) 
    
# [hevc_nvenc @ 0x5601103ca560] No NVENC capable devices
    
# found Error initializing output stream 0:0 -- Error while opening
    
# encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    The memory (on GPUs and system) is more than enough !

    can anyone help me by this ?
