  • Could a compression algorithm be lossless and lossy at the same time ?

    4 avril 2019, par Pasta Fresca

    I 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 [...]

    DEV.LS stands for Decoder, Encoder, Video, Not only intraframe compression, Lossy compression, Lossless compression.

  • Unable to get current time in TCL. can i use flush here ?

    30 novembre 2017, par M. D. P

    unable 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
    
        } 
    
}
    
a

    the output is :

    enter image description here

    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 &
