Add --demuxer-max-packets and --demuxer-max-bytes, which control the maximum size of the packet queue. These can be helpful to avoid excessive memory usage. Memory usage is the reason why there's a limit in the first place. If a file is more or less broken, and audio and video don't line up, the decoders will fill up the packet queue trying to read more audio or video, and the maximum sizes are required to avoid unbounded memory allocation. Being able to override the maximum sizes is useful; either for restricting memory usage further, or enlarging the sizes when attempting to play various broken files.

Introduction

|
============
|
|
|
|
mpv provides access to its internal via the following means:
|
|
|
|
- options
|
|
- commands
|
|
- properties
|
|
- events
|
|
|
|
All of these are important for interfacing both with end users and API users
|
|
(which include Lua scripts, libmpv, and the JSON IPC). As such, they constitute
|
|
a large part of the user interface and APIs.
|
|
|
|
This document lists changes to them. New changes are added to the top.

|
|
- remove --demuxer-readahead-packets and --demuxer-readahead-bytes
|
|
add --demuxer-max-packets and --demuxer-max-bytes
|
|
(the new options are not replacement and have very different semantics)
|
|
- change "video-aspect" property: always settable, even if no video is
|
|
running; always return the override - if no override is set, return
|
|
the video's aspect ratio
|
|
- remove disc-nav (DVD, BD) related properties and commands
|
|
- add "option-info/<name>/set-locally" property
|
|

|
the new total cache size is the sum of backbuffer and the cache size
|
|
specified by --cache-default or --cache
|
|
- add ``track-list/N/audio-channels`` property
|
|
- change --screenshot-tag-colorspace default value
|

|
|
- add --force-seekable, and change default seekability in some cases
|
|
- add vf yadif/vavpp/vdpaupp interlaced-only suboptions
|
|
Also, the option is enabled by default (Except vf_yadif, which has
|
|
it enabled only if it's inserted by the deinterlace property.)
|
|
- add --hwdec-preload
|
|
- add ao coreaudio exclusive suboption
|
|
- add ``track-list/N/forced`` property

|
(and also, "detected-hwdec" is removed)
|
|
- "hwdec-active" is added
