i would like to implement a visualization stuff in emotion. Basically, I
do the following :
1) I put in a pipeline a filesrc and a decodebin
2) I pause the pipeline
3) when a new decoded pad is found:
a) if it's a video stream, I add a queue, a ffmpegcolorspace and a
b) if it's an audio stream, I add a tee and, on the tee, :
i) a queue, an audioconvert, an audioresample and a sink (alsa or
ii) a queue, an audioconvert, a goom, a ffmpegcolorspace and a
In the attached example, I have put an ximagesink for the video and
If I play an audio file, there is no problem, the visualization is
If I play a video file, with one stream, the video is displayed, no
problem. But the audio, even if it starts, stops (~ 6 s) the the
visualization is displayed and the sound is restarting after several
If I play a video file with 2 audio steams, there is no sound at all
(well, in fact, during the first second, that's all)
I think that my pipeline is wrong, but I don't see the problem.
The attached file shows the problem.
For an example of video file with 2 audio streams :
the blood.mkv file
Does soeone see the problem in my pipeline ?
thank you very much
