Why don't you setup the capture/resizer hardware in continuous mode so
that the resizer and capture blocks are linked together? This way, the
resizer hardware gets the frame directly from the capture block (as
opposed to doing each as a
Hi
I have build application which is capturing frames from CMOS. But now I need
to get real frame rate, or average frame rate over some periode of time. Is
in davinci linux some kind of timer which could be use to measure time of
100 frames, or something similar.
Best regards:)

Hi,
I am using DM355 when I was capturing video I saw that it was encoding mpeg4-ts
format. When I want to watch it in my computer it does not work. What it is
problem I do not know. Need I mpeg4-ts decoder ?
Any body can show me some path ?

Hi,
Try this pipeline. I hope that camera you are using will support UYVY format of
raw YUV frame.
gst-launch-0.10 v4lsrc device=/dev/video0 ! capsfilter
caps=video/x-raw-yuv,format=(fourcc)UYVY,width=(int)[16,352],height=(int)[16,288],framerate=(fraction)30/1
! TIVidenc ! queue ! TIViddec !
You can play ts stream by VLC Player .

Hi,

You can do this using gettimeofday().The gettimeofday returns the time in
seconds and microseconds.
gettimeofday(T1, NULL);
// Process 100 frames
gettimeofday(T2, NULL);
The delta between T1 and T2 should give the time for processing 100 frames.

Hello,
I am getting an error message Remote node creation failure(0x80008008)
during algorithm create time for h264 decoder unit server on DVTB. What could
be the likely reason for this error ?
How to fix it?
Thanks,

Still I get the same error,
I have Zippys camera. Which generally work on desktop with v4lsrc.
Any other input

Hi,
Now the error message has gone, but it gets EOS immediately and pipeline
terminates. so no display.
(you can ignore the below invalid format messages, they appear on other
platform as well, but camera works)
gst-launch-0.10 v4lsrc device=/dev/video0 ! ffmpegcolorspace ! TIVidenc ! queue
Purush,
Can you try adding --gst-debug=TI*:4 to the gst-launch line and send the
results to the list?

Hi all,
I am studying JPEG encode/decode on dm355. I know there is an example for the
jpeg in the dvsdk, but its input is a file of *.yuv, if I want to encode it
dynamic,
namely I want to get a jpeg picture from a video capured by CMOS. what should I
change? Can anyone give me some advice?
Hi all,
There is another question:
We all know that we can encode and deode with G.711 on DM355, but its bandwidth
is wide(64KBPS), if I want to run G.729 for save bandwidth, can anyone give me
some advice?
Dose TI give any solutions?
I will appreciate for your applies!!

Well, if the banked interrupts can work, I think it's simpler to just
use banked interrupts or everything.
That was my thought. They basically work ...

This is most likely because you ran out of DSP-side resources (memory, DMA, HW
accelerators, etc).
If you're using Codec Engine 2.00 or later, you can turn on CE_DEBUG to get
more insight:

This patch seems to get me much more reliable performance using the
GPIO banked interrupts on dm355 for the dm9000 driver.
Changes include:
- init GPIO handling along with normal GPIO init
- mask the level-sensitive bank IRQ during handling
- use genirq edge_handler and mask/unmask hooks instead
Kevin, Dave,
We checked this with the hardware team -
The GPIO module does't seem to have the ability to enable/disable the
direct/banked GPIO[0:9] at the GPIO Level (it does via the SET register, but it
doesn't prevent triggering both Interrupts to the CPU). But the option to mask
