Cutting Sections from an Input
|
|
Problem
Given an input media file, the object is to cut pieces from the
file and generate an output file from that.
Solution
A sample application is written. It accepts an input URL
and a list of start and end points specifying the parts to be kept
from the input. A Processor is created for the input URL. A custom
DataSource is then created from the output of the Processor. This
custom DataSource reads from the Processor's output and cuts out
the pieces that are not needed according to the list of start and
end points specified. This DataSources is then used to create a
second Processor to generate the final edited bits. The output from
this Processor is then fed to a file DataSink to generate the final
output file.
Limitations
For MPEG-1 input, the data will be transcoded to JPEG video and
Linear audio before cutting takes place.
As much as possible, the program attempts to maintain A/V synchronization
in the final output file. There are some cases that it may fail.
Specifying the start and end points in video frames unit will only
work for files with frame positioning accuracy.
