couldn't attach the aac_decoder?
Hi all!
I play the mp4 file,but it can not be attatched by the aac decoder which was compiled from the mme source code .I
have included this decoder in the path of lib\media\. The log is as follow.thanks!

Re: couldn't attach the aac_decoder?
> io-media-generic/trackplayer: Couldn't load the libqaacd filter (based on the
> decoder tag)
It seems that your configuration file is wrong. "libqaacd" is not even a filter -- it's a codec library. The filter
that uses that library is "qnx_raac_decoder", and that's what the default configuration file specifies as the decoder
for *.mp4 files. You need both on the target, but the config file must specify the filter, not the codec.
The "Couldn't create a linking filter" message can be caused by all sorts of problems -- not only a missing filter or
librariy, but also a corrupted file or an unsupported format. To verify that you're not missing a filter or a library
that that filter needs, temporarily add a "keepdll" element to your config file that specifies the filter as non-
optional, such as
keepdll {
name = "qnx_raac_decoder"
optional = no
}
This will make io-media fail to start up if some libraries are missing -- if io-media starts up successfully, you'll
know that missing libraries are not the problem. (The keepdll element will make io-media keep the filter and any
associated libraries in memory instead of loading them and unloading as necessary. If that's not what you want, remove
it from your config file after you have fixed your problem.)

The main difference between a codec LIBRARY and a decoder FILTER is that the first is a library with its own API
consisting of some functions and types specific to that library, whereas the second is a DLL that follows the rules of
the QNX multimedia framerork (MMF) about how an MMF filter is expected to connnect to other filters, allocate data
buffers and exchange them with other filters, and so on. A decoder filter typically does not perform the actual
decoding itself -- more often it uses a codec library to do that part of its job. This kind of a filter can be seen as
a wrapper for a codec library that encapsulates the codec's specific API in an MMF-compatible filter DLL.

Re: couldn't attach the aac_decoder?
Hi Wojtek !
thanks for your reply.Your mean is that:
the codec lib provide the decoding function and complete the decoding job. the decoder filter is used to perform
data exchange among the filters. is it right?but what is the relation of them?
otherwise, playing ogg file only need parser filter and oggcodec.Sometimes ,it only need decoder filter and codec
,such as playing mp4v files.but playing mp3 file need both the parser filter and decoer filter .I want to known the
relation of them.The parser filter provide the API interface as follow.does the decoder filter provide the similar API.
thanks very much!

Yes. The relation is that the decoder filter is linked with the codec library and makes calls into its functions. The
decoder receives data, one buffer at a time, from the previous filter (usually a parser), calls the codec's functions to
decode the data into a new buffer, and sends that buffer to the next filter (usually a writer that passes the decoded
data on to a speaker or a screen).
> otherwise, playing ogg file only need parser filter and oggcodec.
Well no, because a parser doesn't usually talk to a codec. A parser's job is to recognize the file format, extract
metadata and other information such as the duration, sampling rate and so on, direct the reader filter to the right
spots in the file when asked to seek to a time position or to fast-forward or rewind, and finally split the raw file
data received from the reader into frames or packets or whatever units of encoded data the decoder expects to receive.
(A decoder usually relies on the parser to find frame boundaries and flag when a frame has been split into two buffers.)
> Sometimes ,it only need decoder filter and codec ,such as playing mp4v files.
I am not aware of an MMF decoder filter capable of playing mp4v files without the help of a parser filter.

About half of those interfaces must be provided by pretty much any MMF filter, including a decoder. Most of the rest
are specific to parsers, because in general only parsers need to worry about extracting metadata from files, convert
time positions to file positions, or generate read requests appropriate for the current set trick-play speed. A decoder
doesn't need to care about most of those things -- it just receives complete encoded frames from the parser and decodes
them one at a time.

Re: couldn't attach the aac_decoder?
Hi Wojtek !
thanks for your particular reply.
I konw the mp4 parser interface as follow.but in genererly,which interface is needed in the decoder filter.
AOInterface_t mp4_parser_interfaces[] =
{
{ "Name", 1, "mp4_parser" },
{ "Version", MM_VERSION, NULL },
{ "MimeInfo", AOMIMEINFO_VERSION, &mime_info },
{ "AODeConstructor", AODECONSTRUCTOR_VERSION, &media_filter },

{ "MediaSetInputPosition",MM_SETINPUT_POSITION_VERSION,&media_setinput_position },
{ "MediaMetadataParser", MM_METADATA_PARSER_VERSION, &md_parser },
{ 0,0,0 }
};
Otherwise,How should I call the coder API in the decoder filter?such as the codec API function:inite_decoder()
,decoder_frame(),end_decoder().How can I add them to the AOInterface_t,is there a rule.thanks very much!

Re: couldn't attach the aac_decoder?
Hi Wojtek !
I have learned some about the media_input and media_output .and known some of the Aoiterface_t of parser filter
and decoder filter from the doc.but I want to known where does the decoder() function is called in the media_input API
or media_output API. In a word ,which API function of the Aointerface_t called the decoder function and complete the
decoding job,such as the API (setmediaoutput ,NextBuffer and so on).
thanks very much!

Re: couldn't attach the aac_decoder?
In a nutshell, a decoder filter's NextBuffer function (in its mediaOutput interface) will typically get some encoded
data from the filter's input channel (by calling the NextBuffer function of the filter connected to the channel), and
then acquire a new buffer, decode the the input data into that buffer by calling the appropriate function in the codec
library, and finally return the decoded buffer (or, more accurately, an MRA containing references to the decoded data in
the buffer). Handling partial frames complicates this general idea a little, but that's a bigger topic.

Re: couldn't attach the aac_decoder?
The "Couldn't load the libmp4_parser filter" message is a little inaccurate -- what it really means that io-media
couldn't attach an instance of the filter to the graph. This can be caused by many possible things. A few suggestions
on how you can narrow it down:
* Is io-media able to load your DLL? If you add it to a "keepdll" element in your io-media config file (without the "
optional=yes" line), io-media will want to load it at startup. It the attempt fails, io-media will log a message to the
system log and exit.
* If the DLL is loaded, are any of your interface functions being called? You can add AO_LOG calls or simply printf to
verify which functions get called. In a parser, the first function that gets called is RateStream() (in the
AOStreamInspector interface). In a decoder it's RateFormat() (in the AOFormatInspector). After either of those
functions returns a positive rating, your Create() call should be called, and then the framework will try to acquire an
input channel and connect it to the previous filter's outpit, by calling the various functions in your MediaInput
interface.

Re: couldn't attach the aac_decoder?
Hi Kailen,
The trick with AO_LOG is that when you compile with NDEBUG defined, the <aoi_errlog.h> header defines AO_LOGLVL to be
AO_LOG_INFO, which causes any DEBUG1 and DEBUG2 messages to be completely #ifdefed out from the binary. Running io-
media with two -D's does not bring them back. If you want DEBUG messages even when you compile with no debug, #define
AO_LOGLVL yourself before including <aoi.h>:
#define AO_LOGLVL AO_LOG_DEBUG2
#include <aoi.h>
What are you using to cause a message when the lib is loaded? Does it actually get loaded successfully? Have you by
any chance tried the keepdll trick I recommended?

Re: couldn't attach the aac_decoder?
Hi Wojtek!
thanks for your reply.
I use io-media-generic -DD -S,as a result ,it come into a loop printing ,please see my log.
In the mp4_parser source code ,I include <aoi_errlog.h> ,and I use
AO_LOG(AO_LOG_INFO,"enter the FormRate API") to get the printing info.as a result ,nothing is printed.
Otherwise,the libh264_decoder.so can not be loaded when I use your recommand method by delete option=yes in the
keepdll.
thanks.

Well if it cannot be loaded than that explains why you're not seeing any of your messages.
If you export an environment variable named DL_DEBUG before starting io-media, the dynamic loader will print out a lot
of information about every shared library that it attempts to load. Hopefully this will tell you why it cannot be
loaded. (Do it with the keepdll option that causes it to exit -- otherwise it'll carry on and flood you with lots and
lots of irrelevant debug info.)

Re: couldn't attach the aac_decoder?
Hi wojtek!
First, I compile mp4_parser project with NDEBUG defined in the project ,then I
add the log in the sniffStream() function as follow(because this function is called firstly).
static int32_t SniffStream(AOIStream_t *sobj)
{
AO_LOG( AO_LOG_DEBUG1, "I entered the function SniffStream ");
---------
}
as a result ,noting is printed,I have no idea.the log is as follow,thanks!

Could that be because you were playing an MP3 file and io-media knew that the correct parser was mpega_parser and not
mp4_parser?

Re: couldn't attach the aac_decoder?
Hi wojtek!
I am sorry ,I mistake the log .The playing file should be mp4.
I use NDEBUG defined to complie the mp4_parser .and in the aoi_errlog.h,I can see the #define AO_LOGLVL AO_LOG_INFO
is available.but the libmp4_parser.so can not be loaded,there are not any info printed which I add by AO_LOG(); the
log is as follow.please give me direction, thanks!

RE: couldn't attach the aac_decoder?
Libmp4_parser is not a filter. The filter for the mp4 parser is
mp4_parser.so

Re: RE: couldn't attach the aac_decoder?
Hi Adrian!
I build a dynamic lib project named mp4_parser ,the result of compiling is libmp4_parser.so.I have modify the io-
media-generic.cfg.(parse=libmp4_parser)
Otherwise,I build the mp4_parser project by the mme source code.thanks!

Re: couldn't attach the aac_decoder?
Hi wojtek!
Secondly, I add the DL_DEBUG=1 before the io-media,but there are noting about the libmp4_parser loaded info.
Otherwise , the aac ,wav and so on can be loaded.the log as follow,thanks very much!

The interesting part would be at the very beginning, while io-media was still doing its initialization (and before and
open() calls had a chance to be received, let alone succed). Also, first I'd try the keepdll option I mentioned eariler
, to verify that the DLL is indeed failing to load. If it loads and the problem is elsewhere, sifting through the
DL_DEBUG output is a waste of time.

I compare my mp4_parser.so binary with the standard mp4_parser.so.I find that the standard mp4_parser.so contain
many tag,but my mp4_parser have no one.the tag is as follow:

can you tell me the function of Tag.Does my mp4_parser lost something to
compile? thanks!
