The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
ffmpeg-formats – FFmpeg formats DescriptionThis document describes the supported formats (muxers and demuxers) provided by the libavformat library. Format OptionsThe libavformat library provides some generic global options, which can be set on all the muxers and demuxers. In addition each muxer or demuxer may support so-called private options, which are specific for that component. Options…
ffmpeg-filters – FFmpeg filters DescriptionThis document describes filters, sources, and sinks provided by the libavfilter library. Filtering IntroductionFiltering in FFmpeg is enabled through the libavfilter library. In libavfilter, a filter can have multiple inputs and multiple outputs. To illustrate the sorts of things that are possible, we consider the following filtergraph. [main] input –> split…
ffmpeg-devices – FFmpeg devices DescriptionThis document describes the input and output devices provided by the libavdevice library. Device OptionsThe libavdevice library provides the same interface as libavformat. Namely, an input device is considered like a demuxer, and an output device like a muxer, and the interface and generic device options are the same provided by…
ffmpeg-codecs – FFmpeg codecs DescriptionThis document describes the codecs (decoders and encoders) provided by the libavcodec library. Codec Optionslibavcodec provides some generic global options, which can be set on all the encoders and decoders. In addition each codec may support so-called private options, which are specific for a given codec. Sometimes, a global option may…
ffmpeg-bitstream-filters – FFmpeg bitstream filters DescriptionThis document describes the bitstream filters provided by the libavcodec library. A bitstream filter operates on the encoded stream data, and performs bitstream level modifications without performing decoding. Bitstream FiltersWhen you configure your FFmpeg build, all the supported bitstream filters are enabled by default. You can list all available ones…

The some verbose…
ffado-diag – print system diagnostic information related to FFADO. Synopsisffado-diag Descriptionffado-diag prints out an extensive collection of diagnostic information about the computer it is run on. Information included is the FFADO version number, the version number of libraries which FFADO depends on, the firewire interface card, interrupt usage, and so on. This is useful for…
dbus – expose the mixer features of connected FFADO devices through DBus Synopsisffado-dbus-server [OPTION…] Descriptionffado-dbus-server exposes the mixer and control features of connected FFADO devices though a DBUS interface. The extent of support for controls on a given device depends entirely on the status of that device’s FFADO driver. By using DBus it is possible…
ffado-bridgeco-downloader – firmware download application for BridgeCo devices Synopsisffado-bridgeco-downloader [OPTION…] OPERATION Descriptionffado-bridgeco-downloader permits firmware updates to be made to BridgeCo (aka BeBoB) devices under Linux. OPERATION describes the action to be carried out. An OPERATION is introduced with the GUID of the device to operate on. This is followed by one of the following keywords…
