Vincent Penquerc'h ca2f96caac vc1parser: do not overwrite buffer 
I do not know the bitstream format, but this seems likely
to be what was intended. Also add a check on the number of
items to read.

Thiago Santos d4105d4b56 camerabin2: On capture error, skip previews 
When the camera source fails to do some capture, skip the next
preview and decrement processing counter.

Lasse Laukkanen 37aa6a9c71 camerabin2: track also preview images with processing counter 
Makes camerabin2 only signal that it is idle after all previews have
been generated, images are captured and saved, and videos have
been finished properly.

René Stadler fd4eb2e220 h264parser: fix access to uninitialized memory 
When vui->timing_info_present is 0, vui->fixed_frame_rate_flag and others
cannot be accessed since they have not been set.

It was also possible that sps->fps_{num,den} end up initialized here.

Brad Smith 8f1a67896b configure: hack around broken mplex 2.0.0 headers in mplex check 
Due to the addition of an unconditional inclusion of config.h in
mjpegtool 2.0.0's stream_params.h header the autoconf test for the
mplex module failed. Hack around this in the same way we did for
mpeg2enc.

Robert Swain e3b7cb8899 fieldanalysis: Don't reset the context on DISCONT 
On discont, the queue of frames was being cleared, but also the
context reset. We only need to clear the queue.

Alessandro Decina 16ce440e7f basevideoencoder: handle failures in start() and stop() 2011-10-31 11:38:58 +01:00
Tommi Myöhänen de138dbc57 basecamerasrc: optimize state changing speed 
Create preview pipeline already in initialization phase. This speeds
up NULL_TO_READY state change. Also implement a separate function for
setting the preview filter element.

This also restricts the preview filter property to work only on
NULL state.

Reynaldo H. Verdejo Pinochet 8eda5fc5dc Disable ext/faad for the android ndk build 
It currently makes the build fail. Idea is to enable
it back again once its building problems get sorted
out.

Thibault Saunier fc09e45108 codecparsers: VC1: Implement Sequence Layer Data Structures 
Instead of having a single VC1SequenceHeader structure, use the 3 structs
from the "Table 265: Sequence Layer Data Structure" of the specification
for the library to be more flexible.

Implement the functions to parse them

Thiago Santos 61a7e6bf38 camerabin2: Check before acessing preview location list 
Only access the preview location if it exists, to avoid acessing
a NULL variable. If the preview location list doesn't exist, it is
likely because the source has posted a preview message after camerabin2
has been put to READY.

Sjoerd Simons 94d9327e2a shm: Add buffer-time property

Thiago Santos acdd2c20f7 basecamerasrc: Set preview pipeline to ready when going to ready 
The preview pipeline should go to ready when the camerasrc goes
to ready, as in ready elements shouldn't be processing data.

Thiago Santos e90e041e52 camerabin2: Add a mutex to avoid concurrent access of preview filename lists 
The preview filename list is acessed whenever a new capture is started, when
camera-source posts a new preview message or on state changes. All of those can
occur simultaneously, so add a mutex to prevent concurrent access.

Thiago Santos 17a00123a4 camerabin: Reset audiosrc timestamping

it to NULL to reset the ringbuffer and then re-seting
the clock that camerabin might not redistribute
