Instead of track IDs you can also provide ISO 639-2 language codes. This will only work for source files that provide language tags for their tracks. They're not simply the track numbers. Default: copy all audio tracks. If the IDs are prefixed with `!` then the meaning is reversed: copy all tracks of this kind but the ones listed after the `!`. |

# MPV
mpv is a based media player. It supports a wide variety of video [file formats](../../files/MIME.md), audio and video [codecs](../../files/media/Codecs.md), and subtitle types. Special input [URL](../../internet/URL.md) types are available to read input from a variety of sources other than disk files. Depending on platform, a variety of different video and audio output methods are supported.

| `-i [input]` | Input a file |
| `-map [input]:[stream]` | Map input streams |
| `-c:[stream]:[input], -codec:[stream]:[input] [codec]` | Specify codec. If `codec` is `copy` stream will not be reencoded. |
| `-t duration (input/output)` | When used as an input option (before `-i`), limit the duration of data read from the input file. |
| `-to position (input/output)` | Stop writing the output or reading the input at position. |
| `-ss position (input/output)` | When used as an input option (before `-i`), seeks in this input file to position. Note that in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. |
| `-sseof position (input)` | Like the `-ss` option but relative to the "end of file". That is negative values are earlier in the file, 0 is at EOF. |
| `-itsoffset offset (input)` | Set the input time offset.<br>offset must be a time duration specification.<br>The offset is added to the timestamps of the input files. Specifying a positive offset means that the corresponding streams are delayed by the time duration specified in offset. |
| `-itsscale scale (input,per-stream)` | Rescale input timestamps. scale should be a floating point number. |
| `-timestamp date (output)` | Set the recording timestamp in the container.<br>date must be a date specification. |
| `-metadata[:metadata_specifier] key=value (output,per-metadata)` | Set a metadata key/value pair.<br>An optional metadata_specifier may be given to set metadata on streams, chapters or programs.<br>This option overrides metadata set with `-map_metadata`.

| `-q[:stream_specifier] q (output,per-stream), -qscale[:stream_specifier] q (output,per-stream)` | Use fixed quality scale (VBR). The meaning of q/qscale is codec-dependent. If qscale is used without a stream_specifier then it applies only to the video stream, this is to maintain compatibility with previous behavior and as specifying the same codec specific value to 2 different [codecs](../../files/media/Codecs.md) that is audio and video generally is not what is intended when no stream_specifier is used. |

| `-attach filename (output)` | Add an attachment to the output file. This is supported by a few formats like [Matroska](../../files/media/Matroska.md) for e.g. fonts used in rendering subtitles. Attachments are implemented as a specific type of stream, so this option will add a new stream to the file. It is then possible to use per-stream options on this stream in the usual way. Attachment streams created with this option will be created after all the other streams (i.e. those created with `-map`or automatic mappings). <br>Note that for Matroska you also have to set the mimetype metadata tag: `ffmpeg -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv` |
| `-dump_attachment[:stream_specifier] filename (input,per-stream)` | Extract the matching attachment stream into a file named filename. If filename is empty, then the value of the filename metadata tag will be used. <br>E.g. to extract the first attachment to a file named ’out.ttf’: `ffmpeg -dump_attachment:t:0 out.ttf -i INPUT`<br>To extract all attachments to files determined by the filename tag: `ffmpeg -dump_attachment:t "" -i INPUT` |
| `-dump_attachment[:stream_specifier] filename (input,per-stream)` | Extract the matching attachment stream into a file named filename.

| `-aspect[:stream_specifier] aspect (output,per-stream)` | Set the video display aspect ratio specified by aspect.<br>aspect can be a floating point number string, or a string of the form num:den, where num and den are the numerator and denominator of the aspect ratio. For example "4:3", "16:9", "1.3333", and "1.7777" are valid argument values.<br>If used together with -vcodec copy, it will affect the aspect ratio stored at container level, but not the aspect ratio stored in encoded frames, if it exists. |
| `-pix_fmt[:stream_specifier] format (input/output,per-stream)` | Set pixel format. Use -pix_fmts to show all the supported pixel formats. If the selected pixel format can not be selected, ffmpeg will print a warning and select the best pixel format supported by the encoder. If pix_fmt is prefixed by a +, ffmpeg will exit with an error if the requested pixel format can not be selected, and automatic conversions inside filtergraphs are disabled. If pix_fmt is a single +, ffmpeg selects the same pixel format as the input (or graph output) and automatic conversions are disabled. |
