python上的Opencv错误 [英] Opencv error on python

问题描述

无论如何CV_FOURCC我使用我得到这个：

no matter what "CV_FOURCC" I use I get this:

OpenCV错误：不支持的格式组合格式（Gstreamer
Opencv backend不支持这种编解码器。）in
CvVideoWriter_GStreamer :: open，file
/usr/src/packages/BUILD/OpenCV-2.2.0/ modules / highgui / src / cap_gstreamer.cpp，
line 489

OpenCV Error: Unsupported format or combination of formats (Gstreamer Opencv backend doesn't support this codec acutally.) in CvVideoWriter_GStreamer::open, file /usr/src/packages/BUILD/OpenCV-2.2.0/modules/highgui/src/cap_gstreamer.cpp, line 489

writer = cv.CreateVideoWriter(
         filename=file,
         fourcc=cv.CV_FOURCC('F', 'M', 'P', '4') ,
         fps=iFps,
         frame_size=(800,600),
         is_color=1)
cv.WriteFrame(writer, cv.LoadImage(frames[i]))

还有/usr/src/packages/BUILD/OpenCV-2.2.0/modules/highgui/src/cap_gstreamer.cpp，不存在。

Also /usr/src/packages/BUILD/OpenCV-2.2.0/modules/highgui/src/cap_gstreamer.cpp, does not exist.

还有 CV_FOURCC（'H'，'F'，'Y'，'U'）会创建空文件。

输入为 *。png ，输出为 *。avi

详情：Opensuse 10.4，OpenCv 2.2.0

编辑：如果我这样做，它会创建一个工作的AVI文件： strong>

If I do this this it creates a working AVI file:

writer = cv.CreateVideoWriter(
         filename=file,
         fourcc=cv.CV_FOURCC('F', 'M', 'P', '4') ,
         fps=iFps,
         frame_size=(800,600),
         is_color=1)
cv.WriteFrame(writer, cv.LoadImage(frames[i]))
del writer # this makes a working AVI

推荐答案

如果我这样做，它会创建一个工作的AVI文件：

writer = cv.CreateVideoWriter(
         filename=file,
         fourcc=cv.CV_FOURCC('F', 'M', 'P', '4') ,
         fps=iFps,
         frame_size=(800,600),
         is_color=1)
cv.WriteFrame(writer, cv.LoadImage(frames[i]))
del writer # this makes a working AVI
