Useful for playback from CD-ROM images or VOB files with junk at the beginning. See also ``--ss``. +--screenshot-filetype=<type> + Set the image file type used for saving screenshots. + + Available choices: + + :png: PNG (default) + :jpg: JPEG + :jpeg: JPEG (same as jpg, but with .jpeg file ending) + +--screenshot-jpeg-quality=<0-100> + Set the JPEG quality level. Higher means better quality. The default is 85. + +--screenshot-png-compression=<0-9> + Set the PNG compression level. Higher means better compression. This will + affect the file size of the written screenshot file, and the time it takes + to write a screenshot. Too high compression might occupy enough CPU time to + interrupt playback. The default is 7. + +--screenshot-template=<template> + Specify the filename template used to save screenshots. The template + specifies the filename without file extension, and can contain format + specifiers, which will be substituted when taking a screeshot. + By default the template is ``shot%n``, which results in filenames like + ``shot0012.png`` for example. + + The template can start with a relative or absolute path, in order to + specify a directory location where screenshots should be saved. + + If the final screenshot filename points to an already existing file, the + file won't be overwritten. The screenshot will either not be saved, or if + the template contains ``%n``, saved using different, newly generated + filename. + + Allowed format specifiers: + + ``%nX`` + A sequence number, padded with zeros to length X. E.g. passing the + format ``%n4`` will yield ``0012`` on the 12th screenshot. The number is + incremented every time a screenshot is taken, or if the file already + exists. The length ``X`` must be in the range 0-9. + ``%f`` + Filename of the currently played video. + ``%F`` + Same as ``%f``, but strip the file extension, including the dot. + ``%p`` + Current playback time, in the same format as used in the OSD. The + result is a string of the form "HH:MM:SS". For example, if the video is + at the time position 5 minutes and 34 seconds, ``%p`` will be replaced + with "00:05:34". + ``%P`` + Similar to ``%p``, but extended with the playback time in milliseconds. + It is formatted as "HH:MM:SS.mmm", with "mmm" being the millisecond + part of the playback time. (Note that this is a simple way for getting + unique per-frame timestamps. Frame numbers would be more intuitive, but + are not easily implementable, because container formats usually use + time stamps for identifying frames.) + ``%tX`` + Specify the current local date/time using he format ``X``. This format + specifier uses the UNIX ``strftime()`` function internally, and inserts + the result of passing "%X" to ``strftime``. For example, ``%tm`` will + insert the number of the current month as number. You have to use + multiple ``%tX`` specifiers to build a full date/time string. + ``%%`` + Replaced with the ``%`` character itself. + --screenh=<pixels> Specify the screen height for video output drivers which do not know the screen resolution like fbdev, x11 and TV-out. |
