[gst-devel] Problems when using osssink in ARM

Thu Sep 20 05:19:11 CEST 2007

 Hi,
Now I'am considering use that mad plugin, but i do not think it's the problem of the decoder.
As I mentioned before, I can convert mp3 files to wav files use this decoder (using the board)and can hear the converted wav in my pc(for my board does not play any media files).At the same time i can not hear the wav file in my arm board either using the wavparse decoder.
Anyway, i'll try the mad later, any more suggestion ?
Many thanks

hi,
can u try playing your mp3 file with mad plugin , i think there is some problem with flump3dec plugin on arm11 . it never worked on my arm board also
mad works fine on arm11.(freescale)
u can also try ffdec_mp3 plugin from gst-ffmpeg on arm11

 Hi Jianjun,
Here is the correct output,the previous one is copied from terminal, and there is someything shows wrong:
/pipeline0/flump3dec0.src: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100, channels=(int)2
/pipeline0/audioconvert0.src: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100, channels=(int)2
/pipeline0/audioconvert0.sink: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100, channels=(int)2
/pipeline0/audioresample0.src: caps = audio/x-raw-int, width=(int)16, depth=(int)16, signed=(boolean)true, endianness=(int)1234, channels=(int)2, rate=(int)48000
/pipeline0/audioresample0.sink: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)44100, channels=(int)2
/pipeline0/osssink0.sink: caps = audio/x-raw-int, width=(int)16, depth=(int)16, signed=(boolean)true, endianness=(int)1234, channels=(int)2, rate=(int)48000
New clock: GstAudioSinkClock
 so here the audio resample src seems to be accord to my osssink, but still the same, no sound came out.what should i do next ?
??2007-09-19??"jianjun.yang.cn"Hi Joyious,
I think the problem lies in that audioresample fails to convert from 44100 hz to 48000 hz. Your oss driver does not support 44100, but the rate of 1.mp3 is 44100. So the audioresample should resample.
But according to your output, rate of audioresample's source pad is different with the one of osssink's sink pad. The former is 0, while the latter is 48000.
I test the pipleline on my PC using osssink. It can work well.
my command line:
gst-launch-0.10 -v filesrc location= /home/jianjun/206851.mp3 ! mad ! audioconvert ! audioresample ! osssink
And its output:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
/pipeline0/mad0.src: caps = audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)32, depth=(int)32, rate=(int)44100, channels=(int)2

?÷???? [gst-devel] Problems when using osssink in ARM
 Hi all,
Now I have ported the gstreamer to ARM 11, and there is a OSS driver for this ARM board. So I am trying to make this sound workI have installed the plugin for ossaudio.But when i trying to play some media file, no sound came out, and the screen just show the PLAYING message ..
some addtional messages:
the osssink does play the audiotestsrc,and sounds a single tone;
the audioconvert works fine when "gst-launch -v filesrc location="/usr/local/bin/1.mp3" ! flump3dec ! audioconvert ! wavenc ! filesink location="/usr/local/bin/1.wav" ",I can hear the wav file on my PC,so the decodec is fine;
even no sound comes out when playing, but there are some noises when pipeline is just prerolling just before PLAYING.
Here are the command and output:
***********************************************************************************************************
mx31# gst-launch -v filesrc location="/usr/local/bin/1.mp3" ! flump3dec ! audioconvert ! audioresample ! osssink

So I'm studying the code of osssink although I am a totally newcomer to this gstreamer and Linux things.
Many Thanks,
Joyious
