Gstreamer dshowvideosrc

[info at mbsoft.biz]

Hi all,

 

can someone help me on this?

 

I want to capture a windows directshow device into an h264 matroska file.

 

But this pipeline produce an empty file: (stall)

 

gst-launch-1.0.exe -v dshowvideosrc device-name="Full HD 1080P PC Camera" !
queue ! videoconvert ! nvh264enc preset=3 bitrate=1024 ! h264parse !
matroskamux ! filesink location="e:\test.mkv

 

if I replace dshowvideosrc with videotestsrc everything is ok.

 

At this point we can think dshowvideosrc is broken..but if I put an
autovideosink I see my webcam without any problem

 

gst-launch-1.0.exe -v dshowvideosrc device-name="Full HD 1080P PC Camera" !
queue ! videoconvert ! autovideosink

so, dshowvideosrc works with an autovideosink but it do not work when
encoding nvh264 or x264enc . 

 

this is the log .. It simply stalls

 

Use Windows high-resolution clock, precision: 1 ms
