tovid-stats: Display summarized statistics of tovid encodings
11
tovid-stats reads encoding statistics from **~/.tovid/stats.tovid**
12
and can display filtered, averaged, correlated or summarized information
13
about all the videos you've encoded with **tovid**. It can also display
14
a 2D graphical scatterplot of data from any two statistic fields.
19
**tovid-stats** //COMMANDS//
21
Where //COMMANDS// is a list of data-filtering commands that operate on
22
specific //FIELD// names (see below for //FIELD// names). Available //COMMANDS//:
24
: **-count** //FIELD//
25
Count total occurrences of unique values in the given field.
26
: **-average** //FIELD_1// {by //FIELD_2//}.
27
Print average values from //FIELD_1// (must be a numerical field). If the
28
**by** clause is included, group averages by distinct values in //FIELD_2//.
29
: **-list** //FIELD_1// by //FIELD_2//
30
List all values of //FIELD_1//, grouped by distinct values in //FIELD_2//.
31
: **-plot** //FIELD_1// by //FIELD_2//
32
Like **-list**, but display a graphical scatterplot of the results.
33
//FIELD_1// must be a numerical field.
34
: **-match** //FIELD// //VALUE//
35
Only display records where //FIELD// has the given //VALUE//. This option may
36
be used to filter the results of subsequent commands.
37
: **-show** '//FIELD// [//FIELD//]...'
38
Display the given fields for all records.
43
The **~/.tovid/stats.tovid** file has accumulated a lot of fields containing data
44
originally intended only for developers. Some fields aren't very useful, or are
45
cryptically named, but here's the complete list anyway:
75
See how many times you've used each version of tovid:
78
tovid-stats -count tovid_version
81
To see a scatterplot of bitrates needed by each format:
84
tovid-stats -plot avg_bitrate by format
87
To filter results, use the -match option. For example, to show the filename
88
and output size of all SVCD-format encodings, do:
91
tovid-stats -match format svcd -show 'final_name final_size'
94
Use multiple -match options to filter further, i.e.:
97
tovid-stats -match format dvd -match tvsys pal [-show etc.]
