Wim Taymans dd3e2b557e collectpads: use the right flushing flag. 
We need to use the pad private flag because the other pad flag is protected with
the pad lock instead.
 2009-06-18 16:50:42 +02:00
Edward Hervey a295d22575 collectpads: Properly handle flushing pads. 
If a pad is flushing, it should not be considered as either eos or
containing data.

Wim Taymans 25067558dc stepping: more stepping improvements 
Update design doc with step-start docs.
Add eos field to step done message
when stepping in reverse, update the segment time field.
Flush out the current step when we are flushing.
 2009-06-12 13:20:36 +02:00
Wim Taymans 23b772664b basesink: post step-start 
when we clip, also stop the stepping.
Don't do QoS when stepping

 2009-06-12 13:16:29 +02:00
Wim Taymans 6e633cbe33 basesink: update segment start/stop for clipping 
When we start stepping, store the start/stop values of the segment before we
install new start/stop values for clipping in non-flushing steps.

for non-flushing steps, update the element start time. For flushing steps, it
does not change because running_time does not advance

Make sure we always perform the stop_stepping operations even when we drop
frames.
 2009-06-09 12:06:35 +02:00
Wim Taymans 72e8d9909c basesink: do proper clipping in stepping 
Update the stop position of the segment so that we clip correctly.
After clipping in non-flushing mode, rerender the remainder of the buffer.
 2009-06-09 10:25:34 +02:00
Wim Taymans 89c42f8506 stepping: do flushing steps correctly 
Note in the docs that a flushing step in PLAYING brings the pipeline to the lost
state and skips the data before prerolling again.

Implement the flushing step correctly by invalidating the current step
operation, which would activate the new step operation.

 2009-06-03 15:39:13 +02:00
Wim Taymans c811d51471 basesink: forget previous times when stepping 
When we start a flushing step operation, forget about the previous stream time
so that the position reporting works correctly.
 2009-06-03 10:39:53 +02:00
Wim Taymans 71a5ebe638 basesink: fix regression in unit tests 
Store the timestamp of the buffer after prerolling. While we are prerolled we

 2009-06-01 13:37:29 +02:00
Wim Taymans 8c54c70d9c basesink: use start_time as the step start 
Use the start_time of the element as the point from where the step operation
starts. This fixes stepping in all paused states.
 2009-06-01 13:37:29 +02:00
Wim Taymans 642bb32196 basesink: catch step cases in _wait_preroll() 
When a subclass is blocking in _wait_preroll() in the _render method, make sure
we can unlock the subclass and detect this return value from the render method.

message.

Pass running_time around so that the stepping code can calculate the elapsed
time correctly.
 2009-06-01 13:37:27 +02:00
Wim Taymans f07b86f18b basesink: move stuff around, more stepping 
Make start and stop_stepping methods and move their invocation in the right
places.

Perform the atual stepping operation where we have full context about the
timestamps.
 2009-06-01 13:37:27 +02:00
Wim Taymans 546c959f26 basesink: first stab at frame stepping in PAUSED 
Unlock the prerolled frame and recheck if we need to step.
Keep a simple counter for the frames we're about to skip while stepping and
preroll/post step_done when stepping finished.

Arnout Vandecappelle c74c3bf1b3 adapter: fix _masked_scan_uint32() at boundaries 
gst_adapter_masked_scan_uint32 could return values smaller than offset
if the first byte(s) of the mask are 0 and the pattern matches the
beginning of the adapter.
Added examples to documentation of gst_adapter_masked_scan_uint32().
Also added some more masked boundary tests.
Fixes #584118
