2c872ad913 baseparse: provide some more initial frame metadata in parse_frame 
... and document accordingly.
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts
6a45c4f65e baseparse: refactor passthrough into format flags 
Also add a format flag to signal baseparse that subclass/format can provide
(parsed) timestamp rather than an estimated one.  In particular, such "strong"
timestamp then allows to e.g. determine duration.

1c89488c50 baseparse: introduce a baseparse frame to serve as context

829507b650 baseparse: allow increasing min_size for current frame parsing only 
Also check that subclass actually either directs to skip bytes or
increases expected frame size to avoid going nowhere in bogus
indefinite looping.

6395b45908 camerabin2: Handle videosink states more carefully

9863feb328 camerabin2: Implement previewing 
Implement previewing functionality using 2 properties. A boolean
(post-previews) that indicates if previews should be posted, and a
GstCaps (preview-caps) to provide the desired preview caps.

image to a pipeline to adapt it to the required caps before posting.

0b4dfa685d mpegtsdemux: fix re-syncing on invalid data after seek 
Or possibly even at startup. If we couldn't find a sync within
the first few bytes, we'd just push more data into the adapter
but never discard any of the invalid data at the beginning, so
would never be able to re-sync.

This patch needs more work so it doesn't cause grave playback
regressions (multi-second freezes) with some files that have
slightly broken timestamps but play fine everywhere else.

07279bac7b camerabin: mode can be only image or video 
No need to check if camerabin is on video mode if it isn't on
image mode as those are the only 2 modes available.

Additionally, if mode gets corrupted somehow and would be neither
image or video it would cause a null pointer dereferencing some
lines of code below, so this is safer.

91b7f2d99e v4l2camerasrc: Implement video capture 
Implements video capture on v4l2camerasrc by using the mode property,
when mode is set to video, the pad probe pushes a new segment
and starts pushing buffers on the pad, when it the property is
sent back to preview, the pad probe pushes an EOS and stops
pushing buffers.

This is controlled by a Recording State variable, that is protected
by the GST_OBJECT_LOCK. I don't think locking for every buffer is
nice, so we could find an alternative lockless way here.

a203ad1aab dvbsuboverlay: Fix more of the blending, so it looks quite good now 
* libdvbsub gives us alpha channel already, not transparency level, so
don't do another "alpha = 255 - alpha", this is done by libdvbsub.
* Fix alpha channel handling in interpolation - assrender had an additional
1bpp alpha bitmap as a possible mask, we don't. So don't use the palette
index array as alpha values; bug from quick code porting long ago to
changing pixel colors (assrender has a single pixel color for whole
regions or something, unlike dvbsub, which has indexed colors).
* Don't forget to reassign our YUV and other local pixel color variables
after shifting to work on the bottom part of a 2x2 subsample block, or
it's obviously very blocky.

Remaining issues in blending:

* Should probably be interpolating or doing something else useful with the
resulting U and V channels, so that most of the source pixel UV values would
actually be actually cared about, except for just one out of possibly four.

* Don't convert AYUV to ARGB in libdvbsub, and then back from ARGB to AYUV in
dvbsuboverlay for no reason

* Re-factor the whole thing to something more like textoverlay blending
* Related to that, perhaps cache the current spu in a good format for quick
blending on each frame, after which the more often called blending parts
might become more straightforward

Push incoming subtitle pages in a FIFO queue (pending_subtitles)

Keep the subtitle page, that is supposed to be blended on top of video
currently, in a separate object variable (current_subtitle). As a
next step we can then pre-render current_subtitle to a better to blend
format.

aca7237878 dvbsuboverlay: Make the libdvbsub callback handler responsible for memory cleanup

the callback handler responsible for memory cleanup, if one is installed.

4a68decb52 dvbsuboverlay: Work with GstClockTime instead of PTS for subtitle timing 
Abuse libdvbsub PTS tracking to just store our running time in it, to get
it back in the callbacks. As GStreamer does its own PTS handling behind our
back (especially for video), we should just sync with video per running time,
not try to do it with PTS, which doesn't seem well accessible for video chain.
We can later relabel dvb-sub.c pts naming convention if wanted, it's just
passing along guint64 values, which GstClockTime fortunately is too.

The current idea is to collect the regions returned by the callback into
a FIFO buffer and pop and pre-render the top one into a separate
quick-to-blend cached format, which is then appropriately blended in the
video chain until the next one on top of the stack reaches the video chains
running time (or the fallback timer hits).

1db547f0b6 gstmpegtsdemux: add temporary **HACK** for dvb subs testing so dvbsuboverlay gets whole packets 
<tpm> leio, what's the mpegts demux hack about?
<leio> my libdvbsub code can't handle cut packets
<leio> so the hack instructs the demuxer to gather full packets before pushing down, but it applies that to more PES packet types than just dvbsub, but I'm not sure if that's a bad thing
<leio> either way, needs a cleaner solution, either in demuxer, or I need to handle cut packets
<tpm> ok, but really it should be fixed in the overlay, right?
<tpm> or a parser be inserted
<leio> the problem is that I don't know from the first packet beforehand if it is a cut one or no
<leio> not
<leio> err, first buffer
<leio> just when I receive the next one I see if it has a valid timestamp on it or not
<leio> so I can't very well queue it up in the chain either, I might be blocking the very last subtitle for no reason or something
<tpm> but you could just drop/ignore packets until you find one, right?
<leio> find what?
<tpm> a complete packet?
<leio> the problem isn't that they aren't complete
<leio> the problem is that they are cut across multiple GstBuffers by the demuxer without the hack
<tpm> sure, I understand that
<tpm> but you can't easily determine if a GstBuffer contains he start fragment of a packet or not?
<leio> I guess I could parse the packet and see if its length is enough, just like the libdvbsub code eventually does too
<leio> I can, it has a timestamp if it's the first chunk
<leio> I just never know if I need to wait for more, without some parsing
<tpm> ah ok
<leio> while the demuxer could just give me an uncut one in the first place
<leio> like it always does for program streams
<leio> that gather_pes is always set in gstmpegdemux, but not in gstmpegtsdemux

e96b8a7b5f camerabin: Avoid assertion on image finishing 
As imgbin_finished() is scheduled from g_idle_add, it might
be run a little later than expected, this can lead to the application
setting camerabin to ready before imgbin_finished() runs. In this case,
the processing counter goes to 0 and an assertion happens.

This patch relaxes the imgbin_finished() check on the processing
counter.

5c2f805199 camerabin: Create imagebin elements when image mode is set in camerabin NULL state 
This patch refactors imagebin element creation and linking into separate functions,
and adds re-using also for imagebin internally created elements.

So this refactoring allows creating imagebin elements already in NULL state when
application sets the image mode, and next state change from NULL to READY will be faster.
This reduces first capture latency.

Earlier the elements were both created and linked in NULL to READY state change.
