Android gstreamer overflow "warning: received more decoded frames 1 than provided 0"

[Yil]

Hi everyone,

I'm new to gstreamer and don't know much about audio streaming, so sorry if this question is too simple. Sorry also if it's already asked (I searched in this forum and stackoverflow but i don't find anything to resolve the problem).

I'm using gstreamer-android1_12_1 in my android application, the pipeline is built like this :

gst_bin_add_many(GST_BIN(mPipeline),
                        uridecodebin, audioconvert1, audioresample, audioconvert2, scaletempo, volume, autoAudioSink, NULL);

The gstreamer library is used in some cpp code and then compiled into static library to be used by android.

The android part of application send a mp3 file uri, begin time and end time to the pipeline sequentially. The problem is, after displaying audio for about 2 minutes (not fixed, sometime it can be longer), I get these errors and the lecture is stopped :

However, when I test the compiled library under linux, I don't get those errors.

I've read https://github.com/jojva/gst-plugins-base/blob/master/gst-libs/gst/audio/audio.c, it seems that it's the "received more decoded frames 1 than provided 0" that cause the stream to stop, but I have no idea about why this happens

Can anyone help me? It'll be also great if some one has some "tips" for debug this kind of problems under android studio. Thanks a lot, and have a nice day.

Regards,
Yilin

Hello,

I get some more information about the issue,  this occurs every time when I send a new file to the pipeline bus. In my folder,  I have about 500 mp3 file, and i'm displaying them one after another.

Thanks for your help.

Regards,
Yilin
