Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...) -

hwcontext_vulkan : rewrite upload/download
18 juillet 2024, par Lynnehwcontext_vulkan : rewrite upload/download
This commit was long overdue. The old transfer dubiously tried to
merge as much code as possible, and had very little in the way
of optimizations, apart from basic host-mapping.The new code uses buffer pools for any temporary bufflers, and
handles falling back to buffer-based uploads if host-mapping fails.Roundtrip performance difference :
ffmpeg -init_hw_device "vulkan=vk:0,debug=0,disable_multiplane=1" -f lavfi \i color=red:s=3840x2160 -vf hwupload,hwdownload,format=yuv420p -f null -

sdp : Add an option for sending RTCP packets to the source of the last packets
13 août 2013, par Martin Storsjösdp : Add an option for sending RTCP packets to the source of the last packets
An SDP description normally only contains the target IP address
and port for the packets. This means that we don’t really have
any clue where to send the RTCP RR packets - previously they’re
sent to the destination IP written in the SDP (at the same port),
which rarely is the actual peer. And if the source for the packets
is on a different port than the destination, it’s never correct.With a new option, we can choose to send the packets to the
address that the latest packet on each socket arrived from.

Some may even argue that this should be the default - perhaps,
but I’d rather keep it optional at first. Additionally, I’m not
sure if sending RTCP RR directly back to the source is
desireable for e.g. multicast.Signed-off-by : Martin Storsjö <martin@martin.st>

Stream mp4 file to multicast using ffmpeg ?
17 décembre 2018, par StuartI have a mp4 video with no sound that I want to stream to a multicast address on a loop, I can connect to the stream group to play but it’s just empty when I play in VLC but the timer in VLC changes as if something is playing.
ffmpeg -re -stream_loop -1 -i testvideo.mp4 -s 640x480 -vcodec copy -f mpegts udp://238.100.100.1:1234
I’ve also noticed that the size doesn’t seem to work either ?
Any help would be great. Thanks
