<div dir="ltr">Hi All<br><br>I am experiencing the same problem in a similar situation. On this case the MJPEG source is at 25 fps. Here is the example:<br><br>gnomevfssrc location=$CAMERA ! typefind ! multipartdemux ! image/jpeg, framerate=25/1 ! jpegdec ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink = location=test0.ogg<br>
<br>The first problem here is that past the jpegdec element, the framerate is ignored and falls back to 0/1. <br>The second problem is that If I try to force the framerate, say, right before ffmpegcolorspace, then the pipeline will not construct.<br>
The third problem occurs if I use the videorate element. The video accumulates frames, but totem only displays a still picture instead of a video.<br><br>Can anyone advice?<br><br>Regards.<br><br>Noe Nieto.<br><br><br><div class="gmail_quote">

With the help from Edward and quite a bit of searching on my own I was<br>
able to solve my problem. The frame rates seemed to be ignored and 1/1<br>
was always assumed until I used the multipartdemux element. Here is the<br>
pipeline that finally worked:<br>
<div class="Ih2E3d"><br>
gnomevfssrc location=<a href="http://url?resolution=320x240%5C&fps=2" target="_blank">http://url?resolution=320x240\&fps=2</a> !<br>
</div>multipartdemux ! image/jpeg,framerate=2/1 ! jpegdec ! theoraenc ! oggmux<br>
! filesink location=test.ogg<br>
<br>
After looking at the docs for multipartdemux, I'm not sure why I got any<br>
video at all before. I guess jpegdec was figuring out some way to parse<br>
the multipart stream into jpegs with the side effect that the frame rate<br>
from the caps filter was ignored....or something. Haven't dug deep enough<br>
into gstreamer to really know. Can anyone shed some light?<br>
