Hi Alan,
In reply to your earlier email, I did try to run the example 'playvideo'
program again on my IMX27 ADS board with your suggested change. Please
note that I am using LTIB rel 3.0 from freescale. I am still unable to
get the display on the panel. I see the following output though:

Decoder maximal reserved 4 buffers.
Actually buffer status:
hardware buffer : 6
software buffer : 0
Set max lateness = 20000000.
-----------------------------------------------------------------------------------------------
I tried to set codec type to "std_mpeg4" and still get same
result/output as above.
Any clue on what am I missing in this setup ??

Rajesh Marathe.

Hi,
I have a setup comprising latest LTIB from CVS and IMX27ADS board. I use
Redhat Linux as OS on my host PC. I took the example "playvideo.c" file
from
"http://www.imxdev.org/wiki/index.php?title=All_Board_Creating_App_Video".
I included alsa-utils, gstreamer plugins and libmad packages as recommended.
The application compiled fine and when I run the same on my ADS board
with the command -
"./playvideo
Kaleidoscope_mp4v_mp3_320x240_30fps_1200kbps_a_48khz_128kbps.mp4"
I get the following output:
-------------------------------------------------------------------
(playvideo:1707): GLib-GObject-CRITICAL **: g_object_set: assertion
`G_IS_OBJECT (ob
ject)' failed
decvd = (nil)
decvd = (nil)
One element could not be created. Exiting.
mx27#
-------------------------------------------------------------------
When I look into the code of playvideo the failure point was the line
g_object_set (decvd, "codec-type", "std_avc", NULL);
The above call fails. My questions are:
1. What should be the codec-type set to ? Am I trying out a wrong file
here ? I changed the codec-type to "std_mpeg4" and still getting same
problem.
?
2. Do I need any other codecs from Freescale to play this video out ? I
have not included any from Freescale ?
I am a newbie to streaming and any help guiding me in right direction
will help a great deal.
Did you comment out line 134?:
gst_element_link (decad, adqueue);
Also check if all FSL plugins are installed:
mx27# gst-inspect | grep mfw
mfw_vpudecoder: mfw_vpudecoder: Freescale: Hardware (VPU) Decoder
mfw_v4lsrc: mfw_v4lsrc: Freescale Video Source plug-in

mfw_avidemuxer: mfw_avidemuxer: FSL Avi Demuxer
mfw_mp4demuxer: mfw_mp4demuxer: freescale-mp4 demuxer plugin
Here on my iMX27ADS it works fine:
