C#根据视频url地址获取视频信息，播放时间，宽度，高度

Sure, I think it's stable enough now. Atleast it's good enough for the use I intended I haven't tested this in anything but WinForms as that is what i need if for. Here's a download link for the source: www.mediafire.com/.../VideoEncoderAsync.rar Changelog: -Fixed filename with spaces bug -Fixed deadlock issue with process execution -Added delegates, events and methods for progress and finish -Added extra fields in VideoFile for video and audio bitrate, framerate, totalframes -Added extraction methods for the above -Added RunProcessAsync -Added EncodeVideoAsync and EncodeVideoAsyncAutoCommand -Added encoder threads *read below* Threads: Threads in ffmpeg is not straight forward. Some codecs dont support multiple threads. The maximum thread count is not the same for codecs. Auto thread count can be used passing 0 as parameter, not all codecs support auto thead count. To disable threads, pass 1 as parameter. Example usage in WinForms: Add methods Progress and Finish Encoder enc = new Encoder(); enc.FFmpegPath = "ffmpeg.exe"; VideoFile videoFile = new VideoFile("C:\\some file.avi"); string outputFile = "C:\\output file.wmv"; enc.OnEncodeProgress += new EncodeProgressEventHandler(Progress); enc.OnEncodeFinished += new EncodeFinishedEventHandler(Finished); enc.EncodeVideoAsync(videoFile, QuickVideoEncodingCommands.WMVVeryHighQualityKeepOriginalSize, outputFile, this, 1); Enjoy Best regards, Anders Tornes
