  10 janvier 2017, par user3292775

  After a lot of trial and error I managed to make all the program work except when coming to load a library. The library is located in the JNI folder. Can someone help me with this error ?

• Fixing a corrupted .MP4 file. which might be a 3gp file

  2 juin 2020, par Tendekai Muchenje

  I have a file called input.MP4 and it is corrupted. It's from a CCTV camera. I tried everything, ffmpeg, VLC convert, no luck. However, I used mediainfo and exiftool and extracted the following info. I am wondering if someone can figure out if I can use any of this info to fix it or convert it to a usable format. I have a copy of it here on my Google Drive

  



  mediainfo gave me this :

File size                           : 5.77 MiB
IsTruncated                         : Yes

• I want to change the file name with exiftool. To “Result of adding time zone (+9) to CreateDate”

  7 décembre 2019, par user3474300

  I shot a video with a sony camera.
  A file with the extension .mp4 was created.
  I want to change the shooting date and time to a file name.
  The environment is Windows10.

  ---

  What I tried

  I first dragged and dropped the .mp4 video file to exiftool (-k) .exe.

  ExifTool Version Number         : 11.76
  
  File Name                       : C0001.MP4
  
  File Modification Date/Time     : 2019:10:23 13:10:49+09:00
  
  File Access Date/Time           : 2019:11:17 21:50:24+09:00
  
  File Creation Date/Time         : 2019:11:17 21:50:21+09:00
  
  MIME Type                       : video/mp4
  
  Major Brand                     : Sony XAVC
  
  Create Date                     : 2019:10:23 04:10:32
  
  Modify Date                     : 2019:10:23 04:10:32
  
  Track Create Date               : 2019:10:23 04:10:32
  
  Track Modify Date               : 2019:10:23 04:10:32
  
  Media Create Date               : 2019:10:23 04:10:32
  
  Media Modify Date               : 2019:10:23 04:10:32
  
  Time Zone                       : +09:00
  
  Last Update                     : 2019:10:23 13:10:32+09:00
  
  Creation Date Value             : 2019:10:23 13:10:32+09:00

  I then typed the following command at a Windows 10 command prompt :

  C:\hoge>"exiftool(-k).exe" -r "-FileNamehoge/C0001.MP4
  
  Warning: Error removing old file - C:/hoge/C0001.MP4
  
      1 directories scanned
  
      1 image files updated
  
  -- press RETURN --

  The following file was created.

  2019-10-23_04-10-32 - C0001.MP4

  ---

  How can I output the following file ?

  I don’t know how to add time zone (+9) to CreateDate.

  2019_1023_131032.MP4
