Member Function Documentation
◆ getData()
|
pure virtual |
Get any underlying raw data available for this object.
- Returns
- The raw data, or null if not accessible.
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
Referenced by com::avpkit::core::IPixelFormat::getYUV420PPixel(), and com::avpkit::core::IPixelFormat::setYUV420PPixel().
◆ getSize()
|
pure virtual |
Get the size in bytes of the raw data available for this object.
- Returns
- the size in bytes, or -1 if it cannot be computed.
Implemented in com::avpkit::core::IVideoPicture, com::avpkit::core::IPacket, com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
◆ getTimeBase()
|
pure virtual |
Get the time base that time stamps of this object are represented in.
Caller must release the returned value.
- Returns
- the time base.
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
Referenced by com::avpkit::core::Stream::stampOutputPacket(), and com::avpkit::core::MediaDataWrapper::wrap().
◆ getTimeStamp()
|
pure virtual |
Get the time stamp of this object in getTimeBase() units.
- Returns
- the time stamp
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
Referenced by com::avpkit::core::MediaDataWrapper::wrap().
◆ isKey()
|
pure virtual |
Is this object a key object? i.e.
it can be interpreted without needing any other media objects
- Returns
- true if it's a key, false if not
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
Referenced by com::avpkit::core::MediaDataWrapper::wrap().
◆ setData()
|
pure virtual |
Sets the underlying buffer used by this object.
This is an advanced method and is not recommended for use by those who don't fully understand how IBuffers work. Implementations of IMediaData may behave in undefined ways if the buffer you pass in is not big enough for what you ask them to do (e.g. they may discard your buffer and allocate a larger one if they need more space). It is up to the caller to ensure the buffer passed in is large enough, and is not simultaneously in use by another part of the system.
- Parameters
-
buffer The buffer to set. If null, this method is ignored.
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::AudioSamples, and com::avpkit::core::MediaDataWrapper.
◆ setTimeBase()
|
pure virtual |
Set the time base that time stamps of this object are represented in.
- Parameters
-
aBase the new time base. If null an exception is thrown.
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
Referenced by com::avpkit::core::Stream::stampOutputPacket().
◆ setTimeStamp()
|
pure virtual |
Set the time stamp for this object in getTimeBase() units.
- Parameters
-
aTimeStamp The time stamp
Implemented in com::avpkit::core::VideoPicture, com::avpkit::core::Packet, com::avpkit::core::MediaDataWrapper, and com::avpkit::core::AudioSamples.
