Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Could a compression algorithm be lossless and lossy at the same time ?
4 avril 2019, par Pasta FrescaI have seen ffmpeg has some codecs (e.g. H.264) which are defined as lossless and lossy at the same time, and from my understanding, lossless and lossy are mutually exclusive : a compression algorithm either losses information or doesn’t.
How is it possible to be lossless and lossy at the same time ?
Running
ffmpeg -codecs 2>/dev/null| grep h264
, I get :DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [...]

Unable to get current time in TCL. can i use flush here ?
30 novembre 2017, par M. D. Punable to get current time for the bellow code :
proc a {} {
for {set i 0} {$i < 3} {incr i} {
puts " $i "
set imagetime [clock format [clock seconds] -format %Y%m%d_%H%M%S]
set videotime [clock format [clock seconds] -format %Y%m%d_%H%M%S]
exec ffmpeg -f dshow -i "video=Integrated Webcam" -s 1280x720 -benchmark c:/test/Image_$imagetime.jpg >& c:/test/image_$imagetime.txt &
after 15000
exec ffmpeg -f dshow -t 00:00:10 -i "video=Integrated Webcam" -s 1280x720 -benchmark c:/test/video_$videotime.avi >& c:/test/video_$videotime.txt &
after 15000
}
}
athe output is :
the problem here is, even though the variable for taking video time and image time is different, it is tacking same time for video and image.
any reason or solution for this ????
can i use flush command ???
can i work with following code :
proc a {} {
for {set i 0} {$i < 3} {incr i} {
puts " $i "
set time [clock format [clock seconds] -format %Y%m%d_%H%M%S]
exec ffmpeg -f dshow -i "video=Integrated Webcam" -s 1280x720 -benchmark c:/test/Image_$time.jpg >& c:/test/image_$time.txt &
after 15000
exec ffmpeg -f dshow -t 00:00:10 -i "video=Integrated Webcam" -s 1280x720 -benchmark c:/test/video_$time.avi >& c:/test/video_$time.txt &
after 15000
}
}
