omx_aacenc hangs in DM8148 SZSDK_5.05.02.00

Hi,

I am trying to use the omx_aacenc element with the following pipeline and the pipeline just hangs (I have verified that the audio generated is OK as I can get the raw data to a file). In fact, when I try to just inpsect the element with gst-inspect, it hangs after the "input-buffers" line and never returns. Is there a fix for this?

gst-launch alsasrc ! 'audio/x-raw-int,width=16,rate=48000' ! omx_aacenc output-format=4 ! gstperf ! fakesink

We need to encode audio to add to a video encoded pipeline...

Hello,

I will check this and I will let you know.

Best Regards,

Well,

Part A of this answer appears to be that the AAC codec is not included by default in the EZSDK, according to this link I stumbled on:

http://processors.wiki.ti.com/index.php/OMX_AAC_LC_Encoder_Integration_in_EZSDK

So the question is, does the gstreamer plugin work with the encoder added or not? Has i been tested?

Thanks.

So I followed the instructions to test the aac encoder according to the webpage.

The DSP code loads successfully without issue, but the example program hangs:

Any change someone could give me a hint how to debug the issue?

Hello,

Here are the steps to run the audio_encode example:

firmware_loader 0 /usr/share/ti/ti-media-controller-utils/dm814x_c6xdsp.xe674 start
firmware_loader 1 /usr/share/ti/ti-media-controller-utils/dm814x_hdvicp.xem3 start
firmware_loader 2 /usr/share/ti/ti-media-controller-utils/dm814x_hdvpss.xem3 start

./audio_encode_a8host_debug.xv5T -i input.pcm -o output.aac -c aaclc -n 2 -b 192000 -s 44100 -f ADTS

Let me know the result.
Best Regards,
Margarita

Hello Margarita,

Yes, this was on the wiki page.

I have solved the issue. I needed to rebuild syslink and reinstall that. It's not clear why, exactly, but that seemed to solve the issue.

The same encode program now works, and it looks like the omx_aacenc gstreamer plugin is also working.

Thank you for responding. I appreciate the attention.

Margarita,

Is it possible that TI would make a minor changes to the two mentioned links above (MP3/AAC LC audio decoder) to change "Rules.mk" to "Rules.make" under 'Integration and Build steps" in in both sections Installing AACLC/MP3 Encoder?

Perhaps the file naming convention is different from the current release of EZSDK 5.05.02.00.

Hi Margarita,

I have done all the suggested things above. I get the error at

OMX_GetHandle(&pHandle, (OMX_STRING) "OMX.TI.DSP.AUDENC",pAppData, pAppData->pCb);

Can you please suggest me what to do.

Regards,

Baz

Hello Baz,

Could you attach me the debug log file?

Could you provide me details what you are executing?

Best Regards,

Margarita
