how to deal with multi audio tracks ?

[toto-2]

Hi guys,
I'm trying to play movies which has multi audio tracks. What i would like to do is to handle these audio tracks: switch to one audio track or mix them together during playback.

I tried to use adder element, it' seems work when mixing. but i don't know how to switch audio when playback. I just unlinked one audio decoder and the adder to disable the audio track. but then all audios are gone:(

Help please~


Regards,
ToTo

Hi ToTo:

I was trying to make a input-selector but it was failed

You may have a try to make it and it has some functions like "switch" and "blocked", it is supposed to useful to complete your goal.

By the way, please give some reply about it.

There are multi track applications using Gonlin. Will that help you?

Thanks for reply.

But I really need some base element/functions to do with that.

I tried to unlink one track source from adder and then release the
request pad. it does works. this track was removed, while the other
tracks play normally. But now i got another problem: i don't know how to
adder it to adder dynamically again...get request pad and link again
seems not work.

Is there any clues?

I you are using playbin2 you can already switch them using the "current-audio"
property. Mixing is not supported there. Could you elaborate the use case for
mixing here? The multiple audio-tracker usually refer to different languages or
encodings (e.g. mp3 stereo, ac3 5.1).
