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:
- o tovid_version
- o final_name
- o length
- o format
- o tvsys
- o final_size
- o tgt_bitrate
- o avg_bitrate
- o peak_bitrate
- o gop_minsize
- o gop_maxsize
- o encoding_time
- o cpu_model
- o cpu_speed
- o in_vcodec
- o in_acodec
- o encoding_mode
- o in_md5
- o in_width
- o in_height
- o quant
- o kbpm
- o enc_time_ratio
- o 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.]
