omxh264 encode isuue

Mario García
Hi all, 
I'm doing test and I can't understand the diference between this two pipelines:

This first, works perfectly, notice the x264enc.
"gst-launch-1.0 multifilesrc location="/home//images/Image_%d.png" ! queue ! pngdec ! videoconvert ! 'video/x-raw, format=(string)I420, width=(int)640, height=(int)512, pixel-aspect-ratio=1/1, interlace-mode=(string)progressive' ! x264enc ! fakesink"

while this one dosn't, notice the omxh264enc:

"gst-launch-1.0 multifilesrc location="/home//images/Image_%d.png" ! queue !  pngdec ! videoconvert ! 'video/x-raw, format=(string)I420, width=(int)640, height=(int)512, pixel-aspect-ratio=1/1, interlace-mode=(string)progressive' ! omxh264enc ! fakesink"

That's the warning that appears in the second pipeline:

"0:00:00.083167916  4273   0x15bb60 WARN                     omx /dvs/git/dirty/git-master_linux/external/gstreamer/gst-omx/omx/gstomx.c:2814:plugin_init: Failed to load configuration file: Valid key file could not be found in search dirs (searched in: /home/ubuntu/.config:/etc/xdg/xdg-ubuntu:/usr/share/upstart/xdg:/etc/xdg as per GST_OMX_CONFIG_DIR environment variable, the xdg user config directory (or XDG_CONFIG_HOME) and the system config directory (or XDG_CONFIG_DIRS)

Can someone explain me where the floating point error might be coming from.? Because as far as I know, I have the omxh264enc hardware, I tested it.

Thanks in advance.
