Merge pull request #20978 from cudawarped:videocapture_read_raw_enchancement
Add capacity to Videocapture to return the extraData from FFmpeg when required

* Update rawMode to append any extra data recieved during the initial negotiation of an RTSP stream or during the parsing of an MPEG4 file header.
For h264[5] RTSP streams this ensures the parameter sets if available are always returned on the first call to grab()/read() and has two purposes:
1) To ensure the parameter sets are available even if they are not transmitted in band.  This is common for axis ip camera's.
2) To allow callers of VideoCapture::grab()[read()] to write to split the raw stream over multiple files by appending the parameter sets to the begining of any new files.
For (1) there is no alternative, for (2) if the parameter sets were provided in band it would be possible to parse the raw bit stream and search for the parameter sets however that would be a lot of work when that information is already provided by FFMPEG.
For MPEG4 files this information is only suplied in the header and is required for decoding.

Two properties are also required to enable the raw encoded bitstream to be written to multiple files, these are;
1) an indicator as to whether the last frame was a key frame or not - each new file needs to start at a key frame to avoid storing unusable frame diffs,
2) the length in bytes of the paramater sets contained in the last frame - required to split the paramater sets from the frame without having to parse the stream.  Any call to VideoCapture::get(CAP_PROP_LF_PARAM_SET_LEN) returning a number greater than zero indicates the presense of a parameter set at the begining of the raw bitstream.

* Adjust test data to account for extraData

* Address warning.

* Change added property names and remove paramater set start code check.

* Output extra data on calls to retrieve instead of appending to the first packet.

* Reverted old test case and added new one to evaluate new functionality.

* Add missing definition.

* Remove flag from legacy api.
Add property to determine if returning extra data is supported.
Always allow extra data to be returned on calls to cap.retrieve()
Update test case.

* Update condition which indicates CAP_PROP_CODEC_EXTRADATA_INDEX is not supported in test case.

* Include compatibility for windows dll if not updated.
Enforce existing return status convention.

* Fix return error and missing test constraints.

d2c1f1131b videoio: drop unnecessary offset for accessing video output buffer
Fix: #21021

NDK API AMediaCodec_getOutputBuffer() returns MediaCodecBuffer::data()
which is actually ABuffer::data(). The returned buffer address is already
adjusted by offset.

More info:
    ABuffer::base() returns base address without offset
    ABuffer::data() returns base + offset

Merge pull request #20591 from fortemSteve:ffmpeg_get_stream_open_time
Add CAP_PROP_STREAM_OPEN_TIME

* Added CAP_PROP_STREAM_OPEN_TIME to videoio module - can be used to query the time at which the stream was opened, in seconds since Jan 1 1970 (midnight, UTC). Useful for RTSP and other live video where absolute timestamps are needed. Only applicable to ffmpeg backends

* use nanoseconds instead of seconds to mark the stream open time, and change the cap prop name to CAP_PROP_STREAM_OPEN_TIME_NSEC

* use microseconds for CAP_PROP_STREAM_OPEN_TIME (nanoseconds rolls over too soon, and milliseconds/seconds requires a division)

* fix whitespace issue

* Reduce PSNR threshold 33->32 (other tests use 30)

* require FFMPEG 4.0+; PSNR 30 as in other tests

* GStreamer AVI-demux plugin not installed in Ubuntu test environment?

* fix build on very old ffmpeg

* fix build on very old ffmpeg

* fix build issues

* fix build issues (static_cast)

* FFMPEG built on Windows without H264 encoder?

* fix for write_nothing test on VAAPI

* fix warnings

* fix cv_writer_get_prop in plugins

* use avcodec_get_hw_frames_parameters; more robust fallback to SW codecs

* internal function hw_check_device() for device check/logging

* two separate tests for HW read and write

* image size 640x480 in encode test

* WITH_VA=ON (only .h headers used in OpenCV, no linkage dependency)

* exception on VP9 SW encoder?

* rebase master; refine info message

* videoio: fix FFmpeg standalone plugin build

* videoio(ffmpeg): eliminate MSVC build warnings

* address review comments

* videoio(hw): update videocapture_acceleration.read test

- remove parallel decoding by SW code path
- check PSNR against the original generated image

* videoio: minor fixes

* videoio(test): disable unsupported MSMF cases (SW and HW)

* videoio(test): update PSNR thresholds for HW acceleration read

* videoio(test): update debug messages

* "hw_acceleration" whitelisting parameter

* little optimization in test

* D3D11VA supports decoders, doesn't support encoders

* videoio(test): adjust PSNR threshold in write_read_position tests

* videoio(ffmpeg): fix rejecting on acceleration device name mismatch

* videoio(ffmpeg): fix compilation USE_AV_HW_CODECS=0, add more debug logging

* videoio: rework VideoAccelerationType behavior

- enum is not a bitset
- default value is backend specific
- only '_NONE' and '_ANY' may fallback on software processing
- specific H/W acceleration doesn't fallback on software processing. It fails if there is no support for specified H/W acceleration.

* videoio(test): fix for current FFmpeg wrapper
