h.264 encoding using x264 and file writing to local disk

[Jonathan]

Hello,

 

I have the same problem.

I try what is in the x264enc documentation :

gst-launch -v videotestsrc num-buffers=1000 ! x264enc qp-min=18 ! \
  avimux ! filesink location=videotestsrc.avi

 

and I get the following :

 

Setting pipeline to PAUSED ...
/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0.GstPad:src: caps = video/x-raw-yuv, format=(fourcc)I420, width=(int)320, height=(int)240, framerate=(fraction)30/1, color-matrix=(string)sdtv, chroma-site=(string)mpeg2

Can someone tell me what am I doing wrong ?

 

I'm using Ubuntu oneiric with the latest package in the standard repository

 

(More info attached)

 

Thanks,

 

Jonathan

Hi,

have you tried to set x264enc property "byte-stream" to "true" ?

regards,
Jan Spurny
