  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • hw_base_encode : make recon_frames_ref optional

    hw_base_encode : make recon_frames_ref optional

    Vulkan supports some stupidly odd hardware, that unfortunately,
    
most modern GPUs happen to be.
    
The DPB images for encoders may be required to be preallocated
    
all at once, and rather than be individual frames, be layers of
    
a single frame.
    

    As the hw_base_encode code is written with the thought that either
    
the driver or the device itself supports sane image allocation,
    
Vulkan does not leave us with this option.
    

    So, in the case that the hardware does not support individual
    
frames to be used as DPBs, make the DBP frames context optional,
    
and let the subsystem manage this.

  • hwcontext_vulkan : add support for mapping multiplane images into CUDA

    hwcontext_vulkan : add support for mapping multiplane images into CUDA

    This patch refactors the CUDA import code to allow for Vulkan images
    
with multiple planes to be mapped.
    

    Currently, a driver bug exists which causes NV12 images to be mapped
    
incorrectly when the memory being mapped contains both planes, the
    
issue has been reported to NVIDIA.
    
yuv420p does work correctly, however.
    

    This is still an improvement, as the code used to crash when trying to
    
map the memory, unless disable_multiplane=1 was given as an option.

  • How to configure ffmpeg for streaming videos from Red5 into Youtube using youtube-v3-api ?

    28 mai 2018, par Alfonso Valdes

    You’ll see my problem is next :

    Currently I’m working to configure youtube-v3-api for live streaming of .flv videos on my Youtube channel using Red 5 service as stated on next link https://www.red5pro.com/docs/server/ffmpegstreaming.html, this is using next commands for streaming on Linux :

    ffmpeg  -i rtmp://127.0.0.1:1935/live/streamname live=1 timeout=2 -vcodec libx264 -s 640x480 -vb 500k -acodec libfdk_aac -ab 128k  -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}
    

    

    
ffmpeg -rtsp_transport tcp -i rtsp://127.0.0.1:8554/live/streamname -acodec copy -vcodec copy -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}

    On this, neither RMTP nor RTSP protocols are working for streaming. Also, I have tried several codecs for audio and video configuring different sizes for each one of them, but none of those have worked.

    The root streaming videos are generated by an IOS/Android app still on development phase.

    The problem comes when no video is displayed on Youtube screen, regardless the video is being sent by Red5 (I confirmed this on my Red5 dedicated server on AWS) and received correctly by Youtube (confirmed by validating on Console), so I have come into a dead end on which I hope you could help me get through.

    Any idea of what could be a possible solution ?

    Thank you.
