Using Accord.Video.FFMPEG, I get "parameter is not valid exception". How can I solve it ?
31 mai 2023, par Sheron BlumentalI want to extract all the frames from an MP4 video file and display them on a PictureBox.


The original code comes from this Q&A : How can I time the presentation and extraction of frames from a video file ?


The exception happens after clicking the start button on the line :


var frame = videoReader.ReadVideoFrame();


The message


System.ArgumentException

 Message=Parameter is not valid.

12 ffmpeg xfade transitions : "option not found"
17 juillet 2023, par nimdaI'm running into a strange error where each of these following 12 of the 56 xfade transitions are throwing errors :


- 

- hlwind
- hrwind
- vuwind
- vdwind
- coverleft
- coverright
- coverup
- coverdown
- revealleft
- revealright
- revealup
- revealdown


























I've tested all filter transitions with the following command, which is being generated by a nodeJS app with the fluent-ffmpeg library, and only the twelve listed above fail with the same error "option not found" :
