u Matches streams with usable configuration, the codec must be defined and If value is not given, matches streams that contain the m: key Matches streams with the metadata tag key having the specified # stream_id or i: stream_id Match the stream by stream id (e.g. Ifīoth are part of the program and match theĪdditional_stream_specifier. p: program_id Matches streams which are in the program with the id program_id. Otherwise, it matches all streams of the specified type. IfĪdditional_stream_specifier is used, then it matches streams whichīoth have this type and match the additional_stream_specifier. Matches all video streams, 'V' only matches video streams which are notĪttached pictures, video thumbnails or cover arts. stream_type stream_type is one of following: 'v' or 'V' for video, 'a' forĪudio, 's' for subtitle, 'd' for data, and 't' for attachments. Is based on the ordering of the streams in the program. Stream numbering is based on the order of the streams as detectedīy libavformat except when a program ID is also specified. Then it selects stream number stream_index from the matching Stream_index is used as an additional stream specifier (see below), "-threads:1Ĥ" would set the thread count for the second stream to 4. Possible forms of stream specifiers are: stream_index Matches the stream with this index. "-codec: copy" would copy all the streams the stream specifier inĪn empty stream specifier matches all streams. Therefore, it would select the ac3 codec for the secondĪ stream specifier can match several streams, so that the option "a:1" stream specifier, which matches the Specifiers are used to precisely specify which stream(s) a given optionĪ stream specifier is a string generally appended to the option Some options are applied per-stream, e.g. Set the boolean option with name "foo" to false. They can be set to false by prefixing the Options which do not take arguments are boolean options, and set Powers of 1024 instead of powers of 1000. If 'i' is appended to the SI unit prefix, the complete prefix willīe interpreted as a unit prefix for binary multiples, which are based on SI unit prefixes, for example: 'K', 'M', or 'G'.
