• Reformat an output in Bash

  5 février 2017, par Kenneth

  I’m using this ffmpeg argument to get the black frame in a file :

  ffmpeg -i ${arrayDesFichiers[$i]} -vf "blackdetect=d=3:pix_th=0.00" -an -f null - 2>&1 | grep black_duration >> log.txt

  Now I’m getting this in my log.txt :

  [blackdetect @ 0x7fd9add06bc0] black_start:0 black_end:3.2 black_duration:3.2

  And I would like to reformat it to something like this :

  black duration : 3.2 seconds

  I’m pretty sure it’s possible in Bash but how ?

• Android video unplayable at iOS

  21 février 2017, par Atif Imran

  I’ve found that videos with codec H.264, MPEG-4 HE AAC V2 have no problem with my code here. But when I use a video of codec H.264, AAC (Sent from Android device) the videos are again black. Now my question is how do I convert a video to iOS playable codec.

• PHP and FFMPEG Remove Code in Video [on hold]

  6 janvier 2015, par user580950

  I have set of videos where i need to remove the code ( check below screen grab as an example ), you can see the code in RED .NOt sure if its possible to do it using PHP & ffmpeg or similar to detect a black box or hash key or serial no and blur out.

  It must be able to use mpeg-ts file input and output with mpeg-ts.

  Detection must be done and blurring must start 5 (configurable) seconds before the black box appears, this means we have to buffer the video and blur out the position where it will appear before it does.
