    how to remove duplicated frame from 00:00:00,00 to 00:00:00,25 (00frame 25frames)section not overall with mpdecimate filter ??
    normally H264 video have some duplicated frames on video start section ..

        i have tried like this , 
    

    
1)  ./ffmpeg -i cated_2-3.UMMJI.MTS -map 0:0 -c:v prores_ks -profile:v 1 -qscale:v 8  -s 1920x1080  -r 29.97  -top 1  -c:a pcm_s16le    -map 0:1 -filter:a:0 "pan=mono|c0=c0" -map 0:1 -filter:a:1 "pan=mono|c0=c1"   -metadata:s encoder="Apple ProRes 422 LT"  -filter_complex "[0]split=2[a][b];[a]trim=end_frame=26,mpdecimate[a];[b]trim=start_frame=25,setpts=PTS-STARTPTS[b];[a][b]concat=n=2:v=1:a=0" -vsync vfr -vf blackdetect=d=0.1:pix_th=.1  cated_2-3.UMMJI_MTS_mpdecimate26_section.mov
    

    
and  tried to check black_frame on out prores mov file 
    
2)./ffmpeg  -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov  -vf blackdetect=d=0.1:pix_th=.1  test.mov
    

    
then , will be shown like below

  • Evolution #4203 (En cours) : Utiliser le type email sur les champs concernés en HTML5

    25 octobre 2018, par b b

    Comme indiqué dans cet article https://www.smashingmagazine.com/2018/10/form-design-patterns-excerpt-a-registration-form/ :

    The input’s type attribute is set to email, which triggers an email-specific onscreen keyboard on mobile devices. This gives users easy access to the @ and . (dot) symbols which every email address must contain.

    On devrait donc, si la config HTML5 est active (voir ce que je dis à ce sujet dans #4202), utiliser ce type sur les inputs des emails (comme c’est déjà le cas dans saisies).

  • Why this shell command doesn't work ? ('command' works but 'command|cat' doesn't work)

    16 octobre 2018, par yabee

    Problem

    The following code outputs like...

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1
    
key_frame=1
    
pkt_pts=0
    
pkt_pts_time=0:00:00.000000
    
--
    
key_frame=1
    
pkt_pts=41041
    
pkt_pts_time=0:00:01.710042
    
--
    
key_frame=1
    
pkt_pts=64064
    
pkt_pts_time=0:00:02.669333
    
--
    
key_frame=1
    
pkt_pts=87087
    
pkt_pts_time=0:00:03.628625
    
--
    
...

    But the folowing one outputs nothing.

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1|cat

    And...

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1
    
key_frame=1
    
key_frame=1
    
key_frame=1
    
key_frame=1
    
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1|cat
    
# Nothing outputted.

    Why ?

    Expected result

    What actually I want to do is

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time
    
pkt_pts_time=0:00:00.000000
    
pkt_pts_time=0:00:01.710042
    
pkt_pts_time=0:00:02.669333
    
pkt_pts_time=0:00:03.628625
    
...

    But its result is

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time
    
# Nothing outputted.

    Grep works correctory exept it’s after ffprobe.

    $ seq 30|grep 1|grep 2

Simple multimedia streams analyzer
    
usage: ffprobe [OPTIONS] [INPUT_FILE]
    

    
You have to specify one input file.
    
Use -h to get full help or, even better, run 'man ffprobe'.

    What is problem ?

    Does grep or ffprobe change its behavior by existence of pipe in this case ?
    Thanks.
