FLV::Body - Flash video file data structure
See FLV::Info
This is a subclass of FLV::Base.
Takes a FLV::File instance and extracts the FLV body from the file stream. This method throws exceptions if the stream is not a valid FLV v1.0 or v1.1 file.
There is no return value.
Create an independent copy of this instance.
Serializes the in-memory FLV body. If that representation is not complete, this throws an exception via croak(). Returns a boolean indicating whether writing to the file handle was successful.
Returns a hash of FLV metadata. See File::Info for more details.
Returns an array of tag instances.
Replace all of the existing tags with new ones. For example, you can remove all audio from a movie like so:
$body->set_tags(grep {!$_->isa('FLV::AudioTag')} $body->get_tags);
Returns the video tags (FLV::VideoTag instances) in the FLV stream.
Returns just the video tags which contain keyframe data.
Returns the audio tags (FLV::AudioTag instances) in the FLV stream.
Returns the meta tags (FLV::MetaTag instances) in the FLV stream.
Returns the start timestamp of the last tag, in milliseconds.
These are convenience functions for interacting with an onMetadata tag at time 0, which is a common convention in FLV files. If the zeroth tag is not an FLV::MetaTag instance, one is created and prepended to the tag list.
onMetadata
See also get_value and set_value in FLV::MetaTag.
get_value
set_value
Consolidate zero or more meta tags into a single tag. If there are more than one tags and there are any duplicate keys, the first key takes precedence.
Create a new header from the body data.
