using FFMPEG commands , can i get the default values of any media file, like resolution, audio codec, video codec..etc.

Question

like for eg. if i enter the output extension '.avi' , i should get the default audio codec used , default video codec used , etc... Is there a command for this ?

Answer 1

Just take a stab here; you would need to declare a codec context and retrieve it from the video stream.

Answer 2

I presume you mean the libavcodec API that the ffmpeg project make available?

void avcodec_get_context_defaults(AVCodecContext *s); is probably the function you want. If you mean the ffmpeg binary, that would be a better question for superuser.
