This can be a comma separated - list of possible formats to try. See ``--of=help`` for a full list of - supported formats. - -``--ofopts=<options>`` - Specifies the output format options for libavformat. - See ``--ofopts=help`` for a full list of supported options. - - Options are managed in lists.

Index numbers start at 0, - negative numbers address the end of the list (-1 is the last). - - ``--ofopts-clr`` - Completely empties the options list. - -``--ofps=<float value>`` - Specifies the output format time base (default: 24000). Low values like 25 - limit video fps by dropping frames. - -``--oautofps`` - Sets the output format time base to the guessed frame rate of the input - video (simulates mencoder behavior, useful for AVI; may cause frame drops). - Note that not all codecs and not all formats support VFR encoding, and some - which do have bugs when a target bitrate is specified - use ``--ofps`` or - ``--oautofps`` to force CFR encoding in these cases. - -``--omaxfps=<float value>`` - Specifies the minimum distance of adjacent frames (default: 0, which means - unset). Content of lower frame rate is not readjusted to this frame rate; - content of higher frame rate is decimated to this frame rate. - -``--oharddup`` - If set, the frame rate given by ``--ofps`` is attained not by skipping time - codes, but by duplicating frames (constant frame rate mode). - -``--oneverdrop`` - If set, frames are never dropped. Instead, time codes of video are - readjusted to always increase. This may cause AV desync, though; to work - around this, use a high-fps time base using ``--ofps`` and absolutely - avoid ``--oautofps``. - -``--oac=<codec>`` - Specifies the output audio codec. This can be a comma separated list of - possible codecs to try. See ``--oac=help`` for a full list of supported - codecs. - -``--oaoffset=<value>`` - Shifts audio data by the given time (in seconds) by adding/removing - samples at the start. - -``--oacopts=<options>`` - Specifies the output audio codec options for libavcodec. - See ``--oacopts=help`` for a full list of supported options. - - .. admonition:: Example - - "``--oac=libmp3lame --oacopts=b=128000``" - selects 128kbps MP3 encoding. - - Options are managed in lists.

By default - the order is unspecified. - -``--ocopyts`` - Copies input pts to the output video (not supported by some output - container formats, e.g. AVI). Discontinuities are still fixed. - By default, audio pts are set to playback time and video pts are - synchronized to match audio pts, as some output formats do not support - anything else. - -``--orawts`` - Copies input pts to the output video (not supported by some output - container formats, e.g. AVI). In this mode, discontinuities are not fixed - and all pts are passed through as-is. Never seek backwards or use multiple - input files in this mode! - -``--no-ometadata`` - Turns off copying of metadata from input files to output files when - encoding (which is enabled by default). |
