• 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).

  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 
  
  
  
  macmini-master:1.  two_file_test khan$ ./ffmpeg  -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov  -vf blackdetect=d=0.1:pix_th=.1  test.mov

  as you can see duplicated frame just changed to black frame , not removed
  this MTS file have 19 duplicated frames !
  also i have checked in FCPX and count how many dupicated frame on out prores mov file ...

• ffmpeg posting to nginx hangs after 90 minutes

  22 octobre 2018, par Harnek Gulati

  I’m using a very simple program to push an ffmpeg stream from my raspberry pi camera to a nginx server. However, it fails after 90 minutes, with almost every single Raspberry Pi I use (I have this code on 12 Raspberry Pis).
  Here is my ffmpeg command :

  raspivid -o - -t 0 -w 640 -h 480 -fps 25 | ffmpeg -re -i - -vcodec copy -hls_time 4 -f hls -hls_list_size 5 -hls_wrap 5 -threads 0  -timeout 5000 -max_reload 20000 -method PUT http://{}:{}/live/{}

  And here is my configuration for nginx.conf :

  #user nobody;
  
  load_module /usr/lib/nginx/modules/ndk_http_module.so;
  
  load_module /usr/lib/nginx/modules/ngx_http_lua_module.so;

              include cors.conf;
  
    }
  
    }
  
  }
  
  
  
  daemon off;

  If anyone can help me, I would deeply appreciate it. I’ve been pulling my hair out trying to figure out this bug. On the raspberry pi, it hangs on this :

  And on the nginx logs, I get :

  I need to set up a way to either a) keep consistent connections longer than 90 minutes or b) detect when the 408 error happens and stop it from hanging.
