Description

I want to write .flv file from Opencv and spent so much time on it...
OpenCV 2.3 Documentation says we can create flv file with this codec

CV_FOURCC('F','L','V','1')
but I am always getting this error.

[flv @ 0x9bf5000] Tag FLV1/0x31564c46 incompatible with output codec id '22'
Please help.... Currently I am using OpenCV 2.3 on Ubuntu 10.10

Try Pastebin code ( http://pastebin.com/HQEvbDCh ) ....Keep one test.avi file in same folder...Please check whether your OpenCV create new.flv

I tried this to write avi file - THIS WORKS

1    CvVideoWriter *vdowriter = cvCreateVideoWriter(
2    "/path/converted.avi",
3    CV_FOURCC('M', 'J', 'P', 'G'),
4    20.0,
5    cvSize(640,480) );

Similarly I tried this to write flv file - THIS DOESNT WORKS
1    CvVideoWriter *vdowriter = cvCreateVideoWriter(
2    "/path/converted.flv",
3    CV_FOURCC('F', 'L', 'V', '1'),
4    25.0,
5    cvSize(640,480) );

I do not see where FLV is mentioned in the documentation. I would consider support for FLV as a feature request, not as a bug

  • Tracker changed from Bug to Feature

#8

It looks like some flv container writer problem. AVI container with flv1 codec works ok.
I add new reproducer with web camera.

flv_reproducer test_video.avi #ok
flv_reporducer test_video.flv #invalid file
