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.]
