我如何获取任何视频文件的帧率，比特率（wmv，mov，H.264，mp4）

Question

i need to fetch the informations like frame per second, Bitrate for video file (wmv,mov,H.264,mp4) im using IMediaDet for getting informations, it working fine for wmv, avi but not for mov and H264, and i am using ffddow codec for playing the mov and other file.

Is there any other way to find these information using DirectShow or any other api.

Answer 1

I guess it will be hard to find one API or something in DirectShow which can tackle various different formats. I would suggest to call

ffmpeg -i filename

and parse the output in order to get the desired informations.
