[gst-devel] Problems when using osssink in ARM

Fri Sep 21 08:01:31 CEST 2007

 Hi all,
I just find even the testaudiosrc is not work either. I said i just heard a short single tone for this testsrc before,but i use the fakesink dump=true, I realize it's a continues sound. Even no matter what kind of media file i played,mp3,wav, it gives the same sound, a noise like tone.
so is there something wrong in my OSS driver or the osssink ?
Thanks,
Joyious

Hi, maybe you can first try replacing the osssink by a fakesink and setting it's property dump=true : gst-launch-0.10 -v filesrc location=~/Media/test.mp3 ! mad ! audioconvert ! audioresample ! fakesink dump=true then try the GST_DEBUG : GST_DEBUG="baseaudiosink:4, audiosink:4" gst-launch-0.10 filesrc location=~/Media/test.mp3 ! mad ! audioconvert ! audioresample ! osssink Cheers, -- Ali On Thu, 2007-09-20 at 09:50 +0800, Joyious He wrote: > 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 ? > > > > > 在2007-09-19，"jianjun.yang.cn" <jianjun.yang.cn at gmail.com> 写道： > Hi Joyious, > > I think the problem lies in that audioresample fails to > convert from 44100 hz to 48000 hz.
