RE: How to integrate another decoder to my existing decoder?
Hey,
As I understand, you have a single video decoder, and you want two
instances running for two channels of the same decoder.
In this case you are okay with having a single folder inside the
/codecs/ folder for myVidDecoder.
I didn't useit yet, but the way you should do it is to declare a single
codec in the server .cfg file (let's say myVidDec), build the server
package.
Afterwards, in the app config file you should declare this codec with
the same name.
In the source files, in the ceapp_init() function, you should call
VIDDEC_create twice with THE SAME codec name, which is the name you
defined in the .cfg files, but each time with a different decHandle.
From here on you have two decoder handles, each of them represents a
different decoder instance with its own state (persistent memory).
In order to understand how exactly to define the decoder name in the cfg
files, the best way is to see in the video_copy example.
Hope I helped,
Erez

There is a good manual here, named Codec Engine Server Integrator
User's Guide: http://focus.ti.com/lit/ug/sprued5b/sprued5b.pdf.
It describes what you need to do to put multiple codecs in an
application. You will need to create a Codec Server that contains both
your algorithms (codecs), since you can load only one server at a time
on the DSP.
You say you tried but didn't state details about what you tried, nor
details about it failing. You will get better support if you provide
more detail, but hopefully the guide I pointed to will be enough to get
you going in the right direction.

Subject: How to integrate another decoder to my existing
decoder?
Hi all,
i am using DM6446. i used the video_copy example to implement my
codec, and i do it. now i do another one based also on the video_copy
example but i want now to integrate both of them.
note:- currently i have 2 seperate folder structures each one
contains the folders named (apps, buildutils, codecs, and
servers)
i want to have only one folder structure for the 2 codecs.
Is there any document/URL/HELP/Suggestions to do this? or this
is not possible to do this at all?
I tryed below but it failed
i modified ceapp_init(), that open, (Engine_open()), the codec
engine and create, (VIDDEC_create()), two video decoders that attached
to it.
as below
--
// reset, load, and start DSP Engine
if ((ceHandle = Engine_open(engineName, NULL, NULL)) ==
NULL)
{
printf(CEapp- ERROR: can't open engine %s\n,
engineName);
goto init_end;
}
else
printf(CEapp- Engine opened %s\n, engineName);
// activate DSP trace collection thread
TraceUtil_start(engineName);
// allocate and initialize video decoder on the engine
decHandle1 = VIDDEC_create(ceHandle, decoderName1, NULL);
if (decHandle == NULL)
{
printf(CEapp- ERROR: can't open codec %s\n,
decoderName);
goto init_end;
}
decHandle2 = VIDDEC_create(ceHandle, decoderName2, NULL);
if (decHandle == NULL)
{
printf(CEapp- ERROR: can't open codec %s\n,
decoderName);
goto init_end;
}
// success
status = 0;
--
also i created two functions named ceapp_decodeBuf1() and
ceapp_decodeBuf2() each one call the corresponding decoder.
that is all i do, am i right or this is totally wrong or there
is still other modifications that should be done and i missed!!

your help is highly appreciated
thanks
