3GP audio support in Eclair

[Uander]

Hi ALL ,

I have observe issue while playing with Android Music app :

 The "Music" application in Android 2.0 {eclair} and 2.1 does not recognize an AMR-NB 
 formatted audio file with the ".3gp" extension although it is listed in the
 Android Supported Media Formats in Android Developer's Guide:-
 
 <http://developer.android.com/intl/ja/guide/appendix/media-formats.html>

 It does recognize the same file with ".amr" extension.

While Music in Android 1.5 {cupcake}  recognizes both AMR-NB formatted audio file with 
 ".3gp" and ".amr" extensions.

I also want to know if it is the current behavior of Music in Android 2.0 and 2.1
or a issue existing ??

If it is discussed earlier in at any thread before please  place the link here .

Thanks :
Uander

Hi,

.3GP files were usually scanned and listed under gallery application
(com.android.gallery or com.android.camera)..
can you check in menu->gallery?

PS.
i've seen the files are listed solely based on file-extension or
container, rather than the encoded data format in it..
just rename .mp3 to .mp4 -> it will appear only in gallery..

My concern is that 3GP extension file (audio AMR-NB format)were detected in Music (cupcake) but not in Eclair neither in Gallery nor in Music application .

Hi,

- have ever seen a file inside gallery or music app? after booting
eclair for first time, i always have to wait like 5 minutes for
mediascanner to finish loading files.. manually you can trigger like
menu -> Dev Tools -> Mediascanner, and wait for /sdcard scan to
complete..

- rename .3gp as like .mp4 and see if it gets played under gallery
app.. i've tried this on a broken setup, where Music app will crash on
opening..

- regarding command line testing, alsa_aplay can test raw and selected formats..
u can use mediaframework tests to test audio/video record/playback
via command line (adb/shell)

source location: ./frameworks/base/media/tests/MediaFrameworkTest
build command: ./make mediaframeworktest

sample test command to play amr
./adb shell am instrument -e class
com.android.mediaframeworktest.functional.MediaPlayerApiTest#testAMRGetDuration
-w com.android.mediaframeworktest/.MediaFrameworkTestRunner

Tried this MediaScanner to scan sdcard  . .3gp not scanned though .
 

- rename .3gp as like .mp4 and see if it gets played under gallery

renamed .3gp to .mp4 .  test_n_3gp.mp4 also not detected in Music and Gallery app .

- regarding command line testing, alsa_aplay can test raw and selected formats..

 alsa_aplay sdcard/test_n_3gp.3gp  gives
Playing raw data 'sdcard/test_n_3gp.3gp' : Unsigned 8 bit, Rate 8000 Hz, Mono
for 2 minutes and then exited . no sound yet .

nothing looks positive yet., can you make sure 'ls /sdcard' is showing
valid conent??

>junit.framework.AssertionFailedError: AMR getDuration

Assertionn is probably due to missing files., and i guess these MTS
test file paths are hardcoded.,
can you place attached file in sdcard in below path and play??
/sdcard/mts_tests/media_api/music/test_amr_ietf.amr

I have placed your test_amr_ietf.amr in  /sdcard/mts_tests/media_api/music . now running command : am instrument -e class com.android.mediaframeworktest.functional.MediaPlayerApiTest#testAMRGetDuration -w com.android.m... says  :

com.android.mediaframeworktest.functional.MediaPlayerApiTest:NOHZ: local_softirq_pending 02

NOHZ: local_softirq_pending 02

NOHZ: local_softirq_pending 02

and it is not exiting .

can you enable logcat before the test? 'logcat &'

Hi ALL  ,

I am still in trouble . My 3gp file (Amr-nb encoded , 3Gp extension audio file ) not getting detected in Eclair .

I tried with this attached FileManager.apk , with this apk , my 3gp file is detected  but agian on trying to play it says "Application not  available".

Is it like only 3gp - video file will be detected that too in Gallery application . And I have only Music in eclair not Gallery ?

Is the problem with my file being audio - 3Gp  not video one ?

Does result should vary from hardware to emulator since emulator doesn't have hardware codecs ?

Anyone else have faced this issue ?


Thanks :
Uander

Why you want to rename and AMR file to 3GP? 3GP files are usually
video and that get listed in Gallery Application. AMR file will get
displayed in Music application. Android documentation does not say
which format/extension will get displayed in which application
(Gallery or Music).

BTW i have list of all valid extension as well as format which are not
getting displayed in either apps so it's all matter of documentation
what exactly is supported in Android Applications.

>>Why you want to rename and AMR file to 3GP? 3GP files are usually
>>video and that get listed in Gallery Application.

3GP is only container, it can contain encoded audio/video data.,
files are listed under gallery or music app based on content type in MIME header. (i was wrong about file extension earlier).
Eclair 2.1 Music app indeed lists .3gp file w amr-nb encoded audio data.

have a check at formats, filetypes supported at
http://developer.android.com/intl/fr/guide/appendix/media-formats.html
