Disc streams are only seekable through the higher-level stream
controls, a byte seek on the slave can only fail and log errors.
avformat_flush() below already resets the demuxer state.
Keep DVD SPU streams always enabled at the slave level and retain the
last subpicture per substream. Re-deliver the retained copy when a sub
track is (re)selected and when the player resets playback state.
demux_disc replaces the chapter list at runtime. Parent each chapter's
tags to the list that contains them, so a replaced list keeps owning
its metadata instead of accumulating it on the demuxer.
A full slave reopen makes libavformat re-probe the stream, which eats
packets around the jump (losing the one-shot menu SPU) and re-bases the
timestamps. DVD cannot change codecs across a jump, so flushing the
slave and refreshing duration/chapters/edition is enough. BD keeps the
full reopen because codecs can change across titles.
Menu activations, HOP_CHANNEL and VTS changes jump the source position.
On this strictly forward stream the demuxer cannot tell where the old
content ends, so buffered pre-jump data would mix with post-jump data.
Return a single EOF at the boundary so the demuxer drains and resets
before any new content flows.
A stream can report a one-shot EOF and then continue producing data
(disc-nav jump boundaries). Also clear a sticky read error, the
underlying source is being reused.
Menu support added bd_read_ext for events but kept the old bd_read
path, leaving two read loops. Use bd_read_ext everywhere and handle
all events in one place.
Track BD_EVENT_STILL/STILL_TIME. Hold playback on indefinite stills and
skip timed stills only. Activations on a held still bump the
discontinuity counter, the disc VM will jump.
DVDNAV_STILL_FRAME means the VM is holding a frame indefinitely (menu
pages, some logos) or for a timed duration. Report the indefinite case
via nav state so the player holds playback at EOF instead of ending
the file, and skip timed stills, which would otherwise stall playback.
We cache some state like title properties, in some cases during deinit
player thread may actually try to read it during demuxer thead read.
Just add a lock, it shouldn't be called frequently to cause too much
synchronization.
Internally the angle stays 0-based (matching the libbluray API), only
the user-visible option/property values are 1-based. BD_EVENT_ANGLE
delivers a 1-based value and is converted on arrival.
The disc VM advances when the stream is read, so in nav mode the cache
must not run ahead of what the user is seeing. Never read ahead (a
looping menu is endless). Never satisfy seeks from the cache either.
This applies to the whole disc session, not only while a menu is on
screen. The VM can jump at any time (BD-J timers, end of title), so
the cache must never run ahead of playback.
Activations still must be able to drive the VM while nothing is
consumed. demux_drive_nav() forces a single read for them.
Adds support for the ARGB overlay callback from libbluray. libbluray
does not convert between its overlay formats, BD-J planes arrive as
ARGB while HDMV planes arrive RLE-encoded, so both callbacks have to
be supported.
When the Java VM is not available, fall back to non-menu playback.
Also bump libbluray requirement to 1.0.2, it was released in 2017.
The disc VM selects audio and subpicture streams itself (menu SPU
highlights, title-authored stream changes on jumps). Follow the VM's
selection on every hop, and turn subtitles on/off with the disc's
sub_visible flag.
The sync only applies while the corresponding track selection is on
auto. An explicitly chosen track (--aid/--sid or runtime cycling) is
never overridden.
This suppresses refresh seeks (e.g. on track switches). A refresh seek
would reposition the disc VM, which breaks menus and can hop to a
different position entirely. Track switching relies on the always-on
readahead of the disc demuxer instead.
User-facing entry point for in-disc menu navigation. The command
forwards an action (up/down/left/right/select/menu/title-menu/popup/
prev/mouse-move/mouse-click) to the current disc stream handler.
The new discnav input section allows binding controls that are only
active while a disc menu is on screen.
Setting the edition property on a disc jumps to the title through the
stream directly, so selecting the currently-playing edition can still
return to it from a menu.
On DEMUX_EVENT_LISTS, re-copy the chapter list and notify the
chapter/edition properties, so a disc title change is reflected in
observed properties and the OSC.
play_current_file picks default tracks once, then leaves them alone.
That leaves later-surfacing streams without a default selection. This
applies to all demuxers with late-added streams, not only discs.
The new player/discnav.c owns the player-side state for the in-disc
menu UI, shared between stream_bluray and stream_dvdnav. Once per
playloop iteration it pulls the stream's nav state and
- pushes the BD menu plane to the OSD (OSDTYPE_DISC_MENU) and the DVD
highlight state to the dvd_subtitle decoders,
- resyncs playback when the disc VM jumped on its own, detected
through the stream's discontinuity counter,
- mirrors the disc's current title into demuxer->edition,
- force-selects a dvd_subtitle track while a DVD menu is up, so the
menu graphics decoded by sd_lavc reach the OSD, and
- enables the {discnav} input section while a menu is interactive.
The per-file state is reset on every new playlist entry.
Playing a disc through the menu means crossing playlist boundaries at
runtime: menu -> title (and back), sub-menu -> sub-menu, title -> title.
Each new playlist can have a different stream count and/or a different
codec mix. The previous slave demuxer was probed once at open and never
refreshed, so after a hop the player either kept decoding stale streams
or saw nothing at all. Tear down and re-open the slave on every nav
discontinuity.
Add HDMV menu support to stream_bluray, activated by opening with
"bd://menu/..." or the global --disc-menu option.
The IG overlay plane arrives through the libbluray YUV overlay
callback. Decode the palettized RLE into a BGRA plane (premultiplied
alpha) and hand it to the player via STREAM_CTRL_GET_NAV_OVERLAY.
STREAM_CTRL_NAV_CMD maps arrow/select/menu/popup/mouse actions onto
bd_user_input() and bd_mouse_select(). Events relevant to the menu
state (title, playlist, menu on/off) are tracked so
STREAM_CTRL_GET_NAV_STATE can report an active menu, and playlist
changes bump discontinuity_id so the player flushes stale packets.
Drive libdvdnav's menu state through the new disc-nav protocol so the
player can show and interact with VMGM and VTSM menus.
STREAM_CTRL_NAV_CMD maps the nav actions onto libdvdnav.
STREAM_CTRL_GET_NAV_STATE reports whether a menu with buttons is on
screen, the highlight rectangle and palette of the focused button, and
the ids of the disc-selected audio/SPU streams.
Menu mode is entered by opening with dvd://menu or --disc-menu, which
starts at the disc's root menu instead of a title.
Define three new stream controls so disc backends (libdvdnav, libbluray)
can expose their in-disc menu/highlight state to the player.
Not used yet, the next commits add the backends and the player side.
Disc demuxers switch titles and playlists at runtime, which changes the
duration and replaces the chapter/edition lists. Add
demux_set_duration() and demux_lists_changed() for demuxers to publish
such updates, and DEMUX_EVENT_LISTS for the player to react.
While here, drop the message to MP_VERBOSE and fix its wording.
"switched to title" is misleading because this is a VTS-change event,
not a title change.
Let the caller pick the OSD object instead of hardcoding EXTERNAL2, so
other bitmap overlay sources can reuse the same path. No functional
change, EXTERNAL2 is still the only user.
Add primaries, transfer, max_luma and video_colorspace arguments.
Allows tagging the colorspace of the overlay bitmap instead of assuming
sRGB. video_colorspace interprets the bitmap in the video's colorspace,
so it is tone mapped exactly like the video. max_luma overrides the
luminance peak of the bitmap. Currently only vo_gpu_next honors these
parameters. vo_gpu keeps its sRGB assumption regardless of the tag.
Fixes#10678
The union member is only valid for SUBBITMAP_LIBASS. The resulting data
is only read for PL_OVERLAY_MONOCHROME, so there was no risk of using
garbage data, but we can make it explicit.
`false` value in the `value or mp.get_property_native(property)`
expression will trigger `mp.get_property_native`, but some
sub-properties cannot be accessed directly, the obtained value is nil.
The queue-full fallback could fire during startup (and after seeks),
before the enhancement-layer decoder produced its first frame.
Gate the fallback on the EL pipeline having delivered at least one
frame since the last reset. Until then a full queue only means the EL
decoder is still spinning up.
The run input is deprecated. Split the monolithic scripts into the same
step layout as the other jobs. Sync the sources once at VM start and
skip the per-step file synchronization, since everything runs inside the
VM anyway.
This will make reading logs easier.
Terminate the block of environment variables with NUL. Previously the block was left unterminated which could cause subprocess spawn failures depending on the array contents after the last item.
The per-stream variant_bitrate is not a reliable selection key. FFmpeg
attributes the whole variant's bandwidth to individual streams, and for
streams shared by multiple variants the value was bogus or missing
depending on the number of variants sharing the stream. The program
metadata always carries the exact HLS variant BANDWIDTH, so use it as
the only key and drop the per-stream fallback.
Note that with `--flatten-editions` tracks are selected by their own
tags, so they may still use bogus values.
For context, there is currently a bug in lavf where, depending on the
number of variants sharing a stream, the stream may or may not get
`variant_bitrate`. This will be fixed in a future FFmpeg release.
