  • 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.

  • Bitrate choice for h265 codec if CRF NOT Supported,MEDIA_CODEC [closed]

    5 septembre 2023, par strider

    How to choose optimal bitrate for encoding to a h265 codec, if h265 codec does NOT support any kind of CRF option ?

    


    I believe the codec supports variable bitrate.

    


    Is there an optimal ratio between bitrates of x264/XVID and h265 codecs ?
I.e. is there a general coefficient that I could multiply given x264 average bitrate to get h265 bitrate ?
(I guess we will have to assume a certain h265 preset here). Let the preset be medium or default for this question.

    


    Usually its for long-term storage and to reduce file size.

    


    Specifically I'm talking about hardware h265/HEVC MEDIA_CODEC for Android and FFMPEG. I'm just learning it, but it does not seem to have many options (does it support PRESET ?).
Any real life sample encoding FFMPEG command for hardware h265 MEDIA_CODEC with FFMPEG (e.g. for a movie) would be very helpful.

    


    Is there a reference table for h265 bitrates for common video formats like Bluray, etc ?

    


    Is there a way to output average video track bitrate with FFMPEG or other free tool ? (usually its x264 or mpeg2).

    


    Unfortunately there's no non-android device I currently have with hardware h265 encoding support or with a multicore CPU.

    fate : adjust AAC encoder TNS test fuzziness

    Tests fails on some ARM builds but it’s close enough so it’s okay.
    
NEON, half-precision floats, rounding errors, who knows.

  • flv live stream audio delay with ffmpeg refresh rate option

    15 janvier 2018, par albert200000

    I have problem with live http flv stream. I’m using the following command and it works great except for the audio. Audio has delay that increasing over time. I can fix the this by removing refresh rate option on the output (-r 30) but then stream latency goes higher for about half second.

    ffmpeg -f v4l2 -threads 0 -video_size 672X420 -i /dev/video1 -f alsa -thread_queue_size 512 -i hw:1,0 -c:a aac -ar 44100 -b:a 128k -c:v libx264 -s 672x420 -r 30 -g 60 -preset superfast -tune zerolatency -strict -2 -f flv rtmp://localhost/live/primary

    Can someone explain why this happening and what possible fixes are ?
    On the client I’m using Chrome with flv.js library.
    On the server Node-Media-Server.
