test case to reproduce freeze (3.55 KB, text/x-csrc)

test case to reproduce freeze

With recent changes to input-selector (cf. #676739) playback freezes some seconds   after a finished seek if ...
... pads are always-ok=TRUE
... input-selector has sync-streams=TRUE
... a multiqueue with buffer is involved (use-buffering=TRUE)

The attached test-prog can be used to reproduce the issue with e.g.:

./is "input-selector sync-streams=true name=sel ! audioconvert ! audio/x-raw-int,width=16 ! audioresample ! alsasink uridecodebin uri=file:/mnt/ltmp/vid/sintel_cropped_multilingual.webm use-buffering=true name=bin ! xvimagesink bin. bin.src1 ! sel. bin.src2 ! sel. bin.src3 ! sel."

No problems though without "use-buffering=true"

Problems disappears when reverting following commit:

    inputselector: Properly sync when changing streams
    
    This adds properties to use the clock time for deciding when
    to drop buffers for inactive pads and a property to buffer all
    not rendered buffers for the active pad to allow pad switching
    without losing any buffers at all.

And no problems with always-ok=FALSE too.

    Fixes bug #677263.
Comment 3 Holger Kaelberer 2012-06-01 18:14:45 UTC 
I tested all, that got stuck before: play well now under same conditions with this commit!

Thanks!
