Add MediaSample to MediaSamplesBlock and back conversion
https://bugs.webkit.org/show_bug.cgi?id=299289
rdar://161095211
Reviewed by Youenn Fablet.
We add the ability to convert a video CMFormatDescription into a VideoTrack.
When converting a MediaSamplesBlock video to a CMSampleBuffer, add handling
of non-displaying sample.
Add {from/to}MediaSample in MediaSamplesBlock to convert respectively from
and to a MediaSampleAVFObjC in order to prepare for serialising the object
over IPC. This allows for C++-only conversion without having to interact
with CMUtilities.
No functional change yet. Tests will be added in a follow-up change which
makes use of those new features.
* Source/WebCore/PAL/pal/cf/CoreMediaSoftLink.cpp:
* Source/WebCore/PAL/pal/cf/CoreMediaSoftLink.h:
* Source/WebCore/platform/MediaSamplesBlock.cpp: Added.
(WebCore::MediaSamplesBlock::toMediaSample const):
(WebCore::MediaSamplesBlock::fromMediaSample):
* Source/WebCore/platform/MediaSamplesBlock.h:
* Source/WebCore/platform/TrackInfo.h: Add BlockType. When converting from a
MediaSample
we record the Box types contained in specific Sample Entries. This guarantees
that even if we encounter a codec not explictly handled (vp8/vp9/avc/hevc)
we will be able to serialise and decode it later without error.
