Audio recorder, cannot find saved file on emulator and internal error (-38)

Hello!

I am trying to write a simple application to record audio on my galaxy watch using native app development in C.

So far I got to the stage when i start the recorder, and after 5 seconds i do a `recorder_commit`.

Apparently the file is saved under

/opt/usr/home/owner/apps_rw/org.example.audiorecorder/data/AUDIO-2019-11-23_19:29:47.3gp

However when I go there using either device manager or shell, there is nothing there at all, all the functions return codes are 0, so everything was a success.

Can you help me find the reason I cannot find the file? What am I missing?

attached the logs. The tag is audiorecorder.

 

BR,

Adam

To add to that, For some reason I cannot get the recorder to work, it returns rerror -38, which is Internal error, in the logs i can see

this:mm_camcorder_audiorec.c: _mmcamcorder_audio_command(530) > file delete(/opt/usr/home/owner/apps_rw/org.example.audiorecorder/data/AUDIO-2019-11-24_01:15:51.3gp)

 

But i have no idea why it's deleted on recorder_commit... :S

 

Any help will be appreciated

do you test this app on emulator or real device?

Adam Kramarczyk

Emulator, havent tried with real device yet. Not even sure how to, or then how to check logs etc. 
It should work on the emulator, right? I mean, thats what the emulator is there for I would have thought, so one can be sure that if it works on emulator, it will work on real devide without breaking it. :P

Paul L

some sample rates/codecs do not work on emulator - change 44100 to 16 kHz and try to use other audio codes.

Adam Kramarczyk

Hi, 

I've tried them all together with 16000, and only MP3, AAC and AMR work for prepare_recorder. The rest wont even do prepare successfully

However the result is the same, commit gives same -38 result.

 

BR,

Adam

Paul L

Try to remove this:

error_code = recorder_attr_set_audio_encoder_bitrate(g_recorder, 28800);

error_code = recorder_set_video_encoder(g_recorder, RECORDER_VIDEO_CODEC_MPEG4);
 
I'm using this API in my app on emulator and device without problems.
 
check what -38 means using:
get_error_message(err);
Adam Kramarczyk

Hi Paul,

I've removed what you suggested, didn't help. And checked the error message, and it's:

Failure, error code = Function not implemented

 

What would that mean?

Hey Paul, 

Thanks for that, I've incorporated your start and stop functions into my app, all the return codes are successful. However I cannot seem to find the file on the device anywhere, to see if anything was actually recorded, is that normal/expected? 

While we're at it, do you know how, or can give some hints on how would I make it so that after stopping the recorder, the file would be sent over bluetooth imidietely to the phone?

 

BR,

Adam

Hey again Paul,

 

I must have looked at something wrong yesterday was very tired, today when I took a second look at the logs, I can still see the "function not implemented" in the logs. So same scenario - probably thats why I cannot find the file.

 

Also, when i just copy paste your code, it wont see the basicui.h header file

Im running tizen studio 3.5 with tizen 5.5 installed

I found the files under a different folder, however they seem to be corrupted, cannot play them, even tho the path given is to /opt/usr/media/Documents/

the files were found under /opt/usr/home/owner/media/Documents/

Yet the application still gives errors:

commit- Funciton not implemented

unprepare- invalid state

destroy - invalid state

 

BR,

Adam

I'm using my own file browser.

Go to Tizen IDE -> Device manager -> click right mouse button on any folder -> open shell and navigate (in shell) to the audio file.

While we're at it, do you know how, or can give some hints on how would I make it so that after stopping the recorder, the file would be sent over bluetooth imidietely to the phone?

You can use SAP (Samsung Accessory Protocol) to exchange data with the phone:

https://developer.samsung.com/galaxy-watch/develop/creating-your-first-app/native-companion/use-sap

 or  "share API" which will launch other app providing share option.

Hey Paul!

Eureka, I've tried to actually install the application on my real watch, and it works flawlessly there! 

Why wont it work on the emulator tho? Any ideas?

 

BR,

Adam

Paul L

Congratulations:) What do you mean? What doesnt work?

Adam Kramarczyk

The recording, As I've mentioned before, I get the "Function not implemented" when running recorder_commit using the emulator, both Tizen 5.5 and Tizen 4.0, Like the emulator is lackluster, but I don't know what the real problem is.
