This file specifies the encoding configuration parameters for each asset. The name of this
XML file is specified via the –a command line parameter. The configurable parameters for
asset.xml are described in
Table 23 , followed by an example file.

Table 23 asset.xml File Parameters
Parameters Tags and Descriptions
<asset_parameters> <videoname> – Video name with full path, if not in the current directory of
the script
<profile_cnt> – Number of multi bitrate files that need to be generated
(default is 3)
<profile_info> — Information regarding the output profiles with following
attributes. The 3 default profiles that will be generated will be at a video
bitrate of 250kbps,500kbps, 800kbps and audio bitrate 64kbps (constant for
all profiles)
•
p – profile number
•
ab – audio bitrate for profile
•
vb – video bitrate for profile
•
width – pixel width for profile
•
height – pixel height for profile
•
deinterlace – option to convert interlaced video, like common analog
television signals, into a non-interlaced form (for example, field to frame
conversion)
<fps> – Frames per second of the video
<format> – Container format for the encoded media (either flv, mp4)
<keyframe_interval> – Key frame positions
The recommended keyframe interval is two seconds; however, this file
specifies the keyframe interval in numbers of frames, not seconds. To have
a two second frame interval, make this value double the value entered for
<fps> (frames per second).
