  • ffmpeg fails to load lensfun database

    5 février 2024, par filibis

    I'm trying to correct lens distortion of a video.

    


    I use below code that I took from here : https://ffmpeg.org/ffmpeg-all.html#Examples-132
(I just change the input and output file paths).

    


    ffmpeg -i input.mov -vf lensfun=make=Canon:model="Canon EOS 100D":lens_model="Canon EF-S 18-55mm f/3.5-5.6 IS STM":focal_length=18:aperture=8 -c:v h264 -b:v 8000k output.mov


    


    But I get this error :

    


    [Parsed_lensfun_0 @ 000002a85a0f7ac0] Failed to load lensfun database from default path
[AVFilterGraph @ 000002a8638fa880] Error initializing filters
Error reinitializing filters!
Failed to inject frame into filter network: Invalid data found when processing input
Error while processing the decoded data for stream #0:0
Conversion failed!


    


    How can I resolve this issue ?

    


    I tried to give full path with db_path command as seen below :

    


    ffmpeg -i input.mov -vf lensfun=make=Canon:model="Canon EOS 100D":lens_model="Canon EF-S 18-55mm f/3.5-5.6 IS STM":focal_length=18:aperture=8:db_path=E:\lensfun-master\data\db\slr-canon.xml -c:v h264 -b:v 8000k output.mov


    


    And I get this similar error :

    


    [Parsed_lensfun_0 @ 0000020b955cb7c0] Failed to load lensfun database from E path
[AVFilterGraph @ 0000020b94e2e9c0] Error initializing filters
Error reinitializing filters!
Failed to inject frame into filter network: Invalid data found when processing input
Error while processing the decoded data for stream #0:0

    Am I doing something wrong ?

    


  • Create a video from JPG without have all pictures at begining with ffmpeg

    30 mars, par Chklang

    I have a game which can create some screenshots, and I want to transform them to mp4 video. So I've the next command :

    


    ffmpeg -framerate 15 -i %06d.png -s hd1080 -vcodec libx264 -r 30 timelapse.mp4


    


    But my game lasts 8h, so, after have auto-compress pictures, I've more than 9To of pictures. So I want to start the ffmpeg process before the end of pictures generation, so I want that ffmpeg wait the next picture to digest it.

    


    How can I do it ?

    Why is the I-frame interval in some cases inconsistent despite of defyning it as a fixed value ?
