How to use MediaOptions.DecoderOptions? (Question) #59

Closed marksugrue closed 3 years ago

marksugrue commented 3 years ago

MediaOptions.DecoderOptions is a dictionary of strings that get passed in on MediaFile.Open(filename, mediaOptions).

I can't seem to find documentation for this. Does it correspond to the ffmpeg commandline parameters? I've tried the following without success

mediaOptions.DecoderOptions.Add("f", "h264");

DecoderOptions does not match all command-line parameters, but only the codec options listed in the FFmpeg documentation: https://www.ffmpeg.org/ffmpeg-codecs.html#Codec-Options. The MediaFile class is designed for extracting frames from a video to process them or export as bitmap data. If you want to simply convert a video file, you should use other libraries that call FFmpeg via command-line.
