@section avi
Audio Video Interleaved muxer.
AVI is a proprietary format developed by Microsoft, and later formally specified
through the Open DML specification.
Because of differences in players implementations, it might be required to set
some options to make sure that the generated output can be correctly played by
the target player.
@subsection Options
It accepts the following options:
@table @option
@item reserve_index_space
@item flipped_raw_rgb @var{bool}
If set to @code{true}, store positive height for raw RGB bitmaps, which
indicates bitmap is stored bottom-up. Note that this option does not flip the
bitmap which has to be done manually beforehand, e.g. by using the @samp{vflip}
filter. Default is @code{false} and indicates bitmap is stored top down.
@item reserve_index_space @var{size}
Reserve the specified amount of bytes for the OpenDML master index of each
stream within the file header. By default additional master indexes are
embedded within the data packets if there is no space left in the first master
@ -815,20 +824,15 @@ The required index space depends on the output file size and should be about 16
bytes per gigabyte. When this option is omitted or set to zero the necessary
index space is guessed.
@item write_channel_mask
Default value is @code{0}.
@item write_channel_mask @var{bool}
Write the channel layout mask into the audio stream header.
This option is enabled by default. Disabling the channel mask can be useful in
specific scenarios, e.g. when merging multiple audio streams into one for
compatibility with software that only supports a single audio stream in AVI
(see @ref{amerge,,the "amerge" section in the ffmpeg-filters manual,ffmpeg-filters}).
@item flipped_raw_rgb
If set to true, store positive height for raw RGB bitmaps, which indicates
bitmap is stored bottom-up. Note that this option does not flip the bitmap
which has to be done manually beforehand, e.g. by using the vflip filter.
Default is @var{false} and indicates bitmap is stored top down.
