• ffmpeg : Cannot open libx265 encoder. Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0

  16 mai 2018, par bnge

  Sorry for my bad English. I am trying to use ffmpeg to convert some image to heic format. Most of them were succeeded, but some large jpeg (seems only jpeg, png will be okay) files not.

  How can I improve my command to compatible all my images, so I can convert them automatically ?

• How to add a comment into a mp3, in a specific language, using ffmpeg [duplicate]

  20 août 2021, par Valery Letroye

  I am fighting with ffmpeg to add a comment in french into a mp3. I want that comment to be displayed within the tab "Details" of the "Properties" window that I can open from Windows Explorer (which is using French as "Display Language").

  


  Ie. : I want this view :

  


  

  


  Unfortunately, I can't find how to do it.

  


  In the illustration above, I did edit the comment directly from the "Details" tag of the "Properties" window. If I look at the Exif info of the file with "exiftool test.mp3", I see

  


  Comment (fra)                   : Test Comment FR


  


  Next, if I open the file test.mp3 with mp3tag (where fra is defined as my language via the Options > Advanced), I see correctly the comment :

  


  

  


  Then, if I replace that comment into "Test Comment FR - Edit", within mp3tag, and save it, here is what I get with exiftool :

  


  Comment (fra)                   : Test Comment FR - Edit
Comment                         : Test Comment FR - Edit


  


  mp3tag has updated the Exif info "Comment (fra)" and added the ID3 tag "Comment".

  


  Now, if I try to add the comment with ffmpeg with the following commands (to clean first all metadata of my previous tests) :

  


  ffmpeg -i test.mp3 -map 0 -map_metadata -1 -c copy test-blank.mp3
ffmpeg -y -i test-blank.mp3 -metadata comment="Test Comment FR - ffmpeg" -c copy test.mp3


  


  Here are the Exif info I get :

  


  User Defined Text               : (comment) Test Comment FR - ffmpeg


  


  This info is not displayed in the "Details" tab of the "Properties" window.
Notice that it is however properly displayed by mp3tag.

  


  I did try to specify the language to ffmpeg with -metadata language="fra", or to use the metadata "Comment" or "Comment (fra)" instead of "comment", but nothing helped.

  


  I am totally lost as not an expert in ID3 and ffmpeg... And I didn't find any trick on Google.
NB. : I am using ffmpeg and exiftool in a Shell console on my Synology, to convert mp4 to mp3 (
ffmpeg version 2.7.7 built with gcc 4.9.3).

  


  Is there anyone experienced with ffmpeg who could guide me ?
PS. : I am even not sure that the comment added by ffmpeg would be displayed by a "English" version of Windows...

  


  A big thx in advance !
