NAME

tovid-stats - Display summarized statistics of tovid encodings

DESCRIPTION

tovid-stats reads encoding statistics from ~/.tovid/stats.tovid and can display filtered, averaged, correlated or summarized information about all the videos you've encoded with tovid. It can also display a 2D graphical scatterplot of data from any two statistic fields.

USAGE

tovid-stats COMMANDS

Where COMMANDS is a list of data-filtering commands that operate on specific FIELD names (see below for FIELD names). Available COMMANDS:

-count FIELD
Count total occurrences of unique values in the given field.
-average FIELD_1 {by FIELD_2}.
Print average values from FIELD_1 (must be a numerical field). If the by clause is included, group averages by distinct values in FIELD_2.
-list FIELD_1 by FIELD_2
List all values of FIELD_1, grouped by distinct values in FIELD_2.
-plot FIELD_1 by FIELD_2
Like -list, but display a graphical scatterplot of the results. FIELD_1 must be a numerical field.
-match FIELD VALUE
Only display records where FIELD has the given VALUE. This option may be used to filter the results of subsequent commands.
-show 'FIELD [FIELD]...'
Display the given fields for all records.

FIELDS

The ~/.tovid/stats.tovid file has accumulated a lot of fields containing data originally intended only for developers. Some fields aren't very useful, or are cryptically named, but here's the complete list anyway:

•
tovid_version
•
final_name
•
length
•
format
•
tvsys
•
final_size
•
tgt_bitrate
•
avg_bitrate
•
peak_bitrate
•
gop_minsize
•
gop_maxsize
•
encoding_time
•
cpu_model
•
cpu_speed
•
in_vcodec
•
in_acodec
•
encoding_mode
•
in_md5
•
in_width
•
in_height
•
quant
•
kbpm
•
enc_time_ratio
•
backend

EXAMPLES

See how many times you've used each version of tovid:

   tovid-stats -count tovid_version

To see a scatterplot of bitrates needed by each format:

   tovid-stats -plot avg_bitrate by format

To filter results, use the -match option. For example, to show the filename and output size of all SVCD-format encodings, do:

   tovid-stats -match format svcd -show 'final_name final_size'

Use multiple -match options to filter further, i.e.:

   tovid-stats -match format dvd -match tvsys pal [-show etc.]
