Wim Taymans 9e08343d5c video-frame: add macros to get frame flags 2012-07-23 13:58:07 +02:00
Wim Taymans f9de2f499b video-frame: use interlacing buffer flags 
Also use the buffer flags to enhance the GstVideoInfo flags in the case where
there was metadata on the buffers.

Sebastian Dröge df08e333d2 video: Correct usage of the base class stream lock 
And also renegotiate if the srcpad requires reconfiguration

Wim Taymans 4b56b731d2 video-frame: add interlace flag 
Add an interlace flag so that we can see if a frame is interlaced or progressive
in the mixed interlace-mode.

Tim-Philipp Müller ed8504e590 video-overlay-composition: fix GSlice alloc/free size mismatch 
Fix copy'n'paste bug which made us allocate a slice of the
size of a rectangle for the overlay composition, but then
free it passing the size of an overlay composition, which
is not something GSlice takes to kindly, resulting in scary
aborts like:

***MEMORY-ERROR***: GSlice: assertion failed: sinfo->n_allocated > 0

Also, g_slice_new already includes a cast, so remove our
own casts, without which the compiler would probably have
told us about this ages ago.

Edward Hervey 8feaebb6eb videodecoder: Expose _negotiate function 
This is to be called by decoders once they have set the output format
in order for (re)negotiation to be triggered as early as possible.

Mark Nauwelaerts f89c7b605f videooverlaycomposition: replace API parameters with required video meta on pixel data 2012-07-17 18:08:11 +02:00
Mark Nauwelaerts d8a9c18e81 videooverlaycomposition: use GstVideoInfo internally and streamline stride handling 2012-07-17 18:08:11 +02:00
Mark Nauwelaerts d03f926162 videoblend: use correct stride when scaling 2012-07-17 18:08:11 +02:00
Wim Taymans eacb9ee554 video: add method to get offset and scale for a format 
Add a method to get the offset and scale values to transform the color values of
a format to their normalized [0.0 .. 1.0] range. This is usually required as
the first step of a colorspace conversion.
 2012-07-13 17:13:10 +02:00
Wim Taymans a18c098f82 video: add option to unpack and truncate the range 
Add an unpack option to specify what to do with the least significant bits of
the destination when the source format has less bits than the destination. By
default we will now copy the most significant bits of the source into the least
significant bits of the destination so that the full color range is represented.
Add an option to leave the extra destination bits 0, which may be faster and
could be compensated for in the element algorithm.

Wim Taymans 866bf89dfe video: fix endianness of the pack formats 2012-07-13 15:35:27 +02:00
Wim Taymans bc78df5d2d video: fix r210 format 
It is an RGB format.

Mark Nauwelaerts db3ce93c51 Revert "videooverlaycomposition: ensure proper buffer copy" 
This reverts commit 1d413ace64.

Plain gst_buffer_copy() is now doing the expected ...

Sebastian Dröge 9002471c93 video: Document buffer ownership of the GstVideoCodecFrame more explicit 
And also the implications of calling the finish() functions.
 2012-07-05 14:29:42 +02:00
Sebastian Dröge 7803ae97e9 videodecoder: Make sure the buffer is writable before changing fields in finish_frame() too 
We can't be sure that we have the one and only reference here either.
 2012-07-05 13:38:48 +02:00
Sebastian Dröge 8e15a2c28d videodecoder: Create a complete subbuffer before pushing 
Otherwise we can't be sure that we are allowed to change the
buffer fields later for clipping.

Wim Taymans 136a3fd37f videoencoder: make PTS and DTS handling more explicit 2012-06-27 16:56:22 +02:00
Wim Taymans c68683c15f videodecoder: avoid crash when getting duration 
Check that we have a valid output_state before attempting to use it to calculate
the duration of a buffer. It is possible that we don't have a state yet, for
example when we are dropping the first buffers.

Wim Taymans 9f591a0bd1 videodecoder: improve PTS and DTS handling 
Also keep track of the DTS and use it to set PTS on keyframes.
Set DTS on outgoing buffers.

Wim Taymans fcc1e1f457 update for bus api changes 2012-06-20 12:34:01 +02:00
Jan Schmidt b7759a4d42 videodecoder: Don't give out bogus frame deadlines 
Make sure the frame deadline was set before calculating the
max_decode_time. Fixes problems with ffmpeg skipping frames when
it doesn't need to, when the input doesn't have full timestamping
(divx in avi)
 2012-06-20 03:45:14 +10:00
Jan Schmidt 9a79a145b1 videodecoder: Remove gst_video_decoder_get_timestamp function 
Interpolating the timestamps from the picture numbers
does more harm than good, getting it wrong in a lot of
cases (especially reverse playback). Removing it in favour
of simply incrementing the timestamps until there's
something better
 2012-06-20 03:40:29 +10:00
Jan Schmidt 45cf9f651b videodecoder: EOS handling for reverse mode. 
Handle EOS correctly in reverse mode by treating it
as a final discont and flushing out whatever we can.
 2012-06-20 01:43:36 +10:00
Jan Schmidt 6718f0cfff videodecoder: misc improvements/changes 
Use g_list_free_full instead of walking lists twice when freeing
them.

Remove pointless clause in gst_video_decoder_chain that doesn't
actually have any effect.

Other changes to make the code slightly more like the 0.11
version.
 2012-06-20 01:43:31 +10:00
Jan Schmidt ffd0f28460 videodecoder: Improve timestamp handling. 
Fix problems with timestamp calculations when the incoming
buffers have sparse timestamps (as for theora) and reverse
playback. Fixes #675773
