• ffmpeg : Decoding error : Invalid data found when processing input (.CR2 file)

  16 septembre 2023, par PZL

  I am writing a script to process .CR2 images taken with my Canon EOS M5 camera, but am running into this error (using ffmpeg on Windows) :

Conversion failed!


  


  The .CR2 file can be opened normally in Photoshop and Windows Photo Viewer (with the raw image extension).

  


  I can get around this issue by converting the image to JPEG using another program, but I would to work with the original file if possible.

  


• avformat/ffrtmpcrypt : Fix int-conversion warning

  avformat/ffrtmpcrypt : Fix int-conversion warning
  The gcrypt definition of `bn_new` used to use the return statement
  
  on errors, with an AVERROR return value, regardless of the signature
  
  of the function where the macro is used - it is called in
  
  `dh_generate_key` and `ff_dh_init` which return pointers. As a result,
  
  compiling with gcrypt and the ffrtmpcrypt protocol resulted in an
  
  int-conversion warning. GCC 14 may upgrade these to errors [1].
  This patch fixes the problem by changing the macro to remove `AVERROR`
  
  and instead set `bn` to null if the allocation fails. This is the
  
  behaviour of all the other `bn_new` implementations and so the result is
  
  already checked at all the callsites. AFAICT, this should be the only
  
  change needed to get ffmpeg off Fedora's naughty list of projects with
  
  warnings which may be upgraded to errors in GCC 14 [2].

• File conversion to mp3 returning failure everytime using flutter package ffmpeg_kit_flutter

  6 novembre 2024, par Sanath balthar

  I am trying to convert a .wav audio file generated from a flutter's text to speech package - "flutter_tts" to mp3 file but it is failing everytime.
I have written the below code for file conversion. I have imported the package ffmpeg_kit_flutter. It doesnt even show why the conversion is failing.
I have looked up in stackoverflow and other sites but could not find any relevant solutions. I am using vscode as editor. I have attached flutter doctor output below as well. Could anyone please guide me ? Let me know if you need more information.
