@item use_absolute_path |
|
|
|
|
Allows loading of external tracks via absolute paths, disabled by default. |

@item seek_streams_individually |
|
|
|
|
When seeking, identify the closest point in each stream individually and demux packets in |
|
|
|
|
that stream from identified point. This can lead to a different sequence of packets compared |
|
|
|
|
to demuxing linearly from the beginning. Default is true. |
|
|
|
|
|
|
|
|
|
@item ignore_editlist |
|
|
|
|
Ignore any edit list atoms. The demuxer, by default, modifies the stream index to reflect the |
|
|
|
|
timeline described by the edit list. Default is false. |
|
|
|
|
|
|
|
|
|
@item advanced_editlist |
|
|
|
|
Modify the stream index to reflect the timeline described by the edit list. @code{ignore_editlist} |
|
|
|
|
must be set to false for this option to be effective. |
|
|
|
|
If both @code{ignore_editlist} and this option are set to false, then only the |
|
|
|
|
start of the stream index is modified to reflect initial dwell time or starting timestamp |
|
|
|
|
described by the edit list. Default is true. |
|
|
|
|
|
|
|
|
|
@item ignore_chapters |
|
|
|
|
Don't parse chapters. This includes GoPro 'HiLight' tags/moments. Note that chapters are |
|
|
|
|
only parsed when input is seekable. Default is false. |
|
|
|
|
|
|
|
|
|
@item use_mfra_for |
|
|
|
|
For seekable fragmented input, set fragment's starting timestamp from media fragment random access box, if present. |

|
|
|
|
@item export_xmp |
|
|
|

Export entire contents of @var{XMP_} box and @var{uuid} box as a string with key @code{xmp}. Note that |
