7a9e11ae1b v4l2codecs: vp9: Fix duplicating a duplicated picture
Duplicating a picture what was already a dup was leading to a crash. Rename
the custom picture flags as HOLDS_BUFFER to make its meaning clear. Then save
then ref and store the picture as userdata, so it can be obtained when
duplicating. Finally, mark the doplicated as HOLDS_BUFFER to avoid thinking it
holds a request.

13944cf3ee v4l2codecs: vp9: Make compressed hdr control optional
This is to supported by Mediatek VP9 driver. Mediatek handles
the forward probabilities in hardware hence does not need and
does not implement support for
V4L2_CID_STATELESS_VP9_COMPRESSED_HDR.

6434d69f8c codecs: Stop claiming constness for refcounted object
It's almost pointless and makes little sense as subclass might
want to modify refcount of the object or so. And all subclasses
are already casting them to non-const version as well.
In a general sense, we need to avoid passing refcounted object
with const qualifier.

47bfa71530 v4l2codecs: h264: Improve ABI check
This moves the ABI check to the registration, so we don't expose
decoders with the wrong ABI or that are just broken somehow. It
also makes few enhancement:

- Handle missing, but required controls
- Prints the controls macro name instead of id

This should fix RK3399 support with a currently release minor
regression in the Hantro driver that cause errors.

d7363bd838 v4l2codecs: Fix debug assertion in register functions
As now, we warn if the decoder have no support src pixel format, but that
warning is called before the type (hence the debug category) is initialized.
Fix this by moving the debug category init out of the type initialization,
into the register funcitons.

This will fix an assertion that occures in the register function and allow
relevant log to be seen by the users.

107088a658 v4l2codecs: Unify the src template caps format
Notably NV12_4L4 ended up being applied to only VP9 decoder. This fixes the
situation by using a central define for all static src pad templated formats.

7e875ddb2c v4l2codecs: mpeg2: Fix selected sizeimage
Due to a copy paste bug, the bitdepth was never set and that was leading
to requesting sizeimage of 0. Previously that worked since the driver
would in that case pick a size for us. But now the we bumped the minimum
to 4KB, the driver happily allocate 4KB of bitstream which lead to
decoding error.

As MPEG2 have a fixed bitdeph of 8, use a define instead of the run-time
variable.

d04fba93f8 v4l2codecs: vp9: Remove uneeded picture data
The GstV4l2Request now holds a reference on the picture buffer and is
recounted already. This effectively removes usage of GRefCount which is only
available in GLib 2.58, while we support 2.56.

Fixes #910

83933b7772 v4l2codecs: h264: Properly set pic_num/frame_num
The V4L2 uAPI uses pic_num for both PicNum and ShortTermPicNum. It also
doe the same for both FrameNum and LongTermFrameIdx. This change does
not change the fluster score, but fixed a visual corruption noticed
with some third party streams.

3846b0563a v4l2codecs: Fix segfault when destroying non-detached allocator
The GstV4l2CodecAllocator dispose function clears `self->decoder` but
the finalize function then tries to use it if the allocator has no been
detached yet.

Fix by detaching in the dispose function before we clear
`self->decoder`.

e322745763 codecs: h264decoder: Use GstFlowReturn everywhere
boolean return value is not sufficient for representing the reason
of error in most cases. For instance, any errors around new_sequence()
would mean negotiation error, not just *ERROR*.
And some subclasses will allocate buffer/memory/surface on new_picture()
but it could be failed because of expected error, likely flushing
