Hello i need a some istructions to use ffmpeg, I would like a code to get media file info
16 juillet 2014, par user3547175I want to start by saying that i don’t know how to use FFMPEG in C#. I have a program that reads the information of a media file, I use this code about resolution, bitrate
var player = new WindowsMediaPlayer();
var clip = player.newMedia(file.FullName);
lblLenght_.Text = (TimeSpan.FromSeconds(clip.duration)).ToString();
ShellFile shellFile = ShellFile.FromFilePath(file.FullName);
lblFPS_.Text = (shellFile.Properties.System.Video.FrameRate.Value / 1000).ToString();
lblHeight_.Text = shellFile.Properties.System.Video.FrameHeight.Value.ToString() + " px";
lblWidth_.Text = shellFile.Properties.System.Video.FrameWidth.Value.ToString() + " px";
lblResolution_.Text = shellFile.Properties.System.Video.FrameWidth.Value.ToString() + "x" + shellFile.Properties.System.Video.FrameHeight.Value.ToString() + " px";
blBitrate_.Text = (shellFile.Properties.System.Video.TotalBitrate.Value / 1000).ToString() + " kb/s";but the problem is that
ShellFile
supports only a few formats, so I found some FFMPEG uses but I don’t know how to work with it. Can someone post the solution or some link to learn how to use it about my problem ? -

Revision cdffeaaae0 : Add mode info arrays and mode info index. In non frame-parallel decoding, this
10 juin 2014, par hkuangChanged Paths :
Modify /vp9/common/vp9_alloccommon.c
Modify /vp9/common/vp9_onyxc_int.h
Add mode info arrays and mode info index.In non frame-parallel decoding, this works the same way as
current decoding scheme. Every time after decoder finish
decoding a frame, it will swap the current mode info pointer
and previous mode info pointer if the decoded frame needs
to be shown. Both mode info pointer and previous mode info
pointer are from mode info arrays.In frame-parallel decoding, this will become more complicated
as current frame’s mode info pointer will be shared with next
frame as previous mode info pointer. But when one decoder
thread finishes decoding one frame and starts to work on next
available frame, it needs to retain the decoded frame’s mode
info pointers until next frame finishes decoding. The mode info
index will serve this purpose. The decoder will use different
buffer in the mode info arrays and use the other buffer to save
previous decoded frame’s mode info.Change-Id : If11d57d8eb0ee38c8876158e5482177fcb229428
