@subsection Options
|
||||||
|
|
||||||
|
It accepts the following options:
|
||||||
|
|
||||||
|
@table @option
|
||||||
|
@item reserve_index_space
|
||||||
|
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
|
||||||
|
index and are linked together as a chain of indexes. This index structure can
|
||||||
|
cause problems for some use cases, e.g. third-party software strictly relying
|
||||||
|
on the OpenDML index specification or when file seeking is slow. Reserving
|
||||||
|
enough index space in the file header avoids these problems.
|
||||||
|
|
||||||
|
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
|
||||||
|
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}).
