Even though only 1 seek range is supported at the time.
Other than preparation for possibly future features, the main gain is
actually that we finally separate the reporting for the buffering, and
the seek ranges. These can be subtly different, so it's good to have a
clear separation.
This commit also fixes that the ts_reader wasn't rebased to the start
time, which could make the player show "???" for buffered cache amount
in some .ts files and others (especially at the end, when ts_reader
could become higher than ts_max). It also fixes writing the cache-end
field in the demuxer-cache-state property: it checked ts_start against
NOPTS, which makes no sense.
ts_start was never used (except for the bug mentioned above), so get rid
of it completely. This also makes it convenient to move the segment
check for last_ts to the demux_add_packet() function.
Even if the demuxer cache does not multiple ranges yet. This is to
reduce the pain should caching of multiple ranges ever be implemented.
Also change it from the sub properties stuff to return a mpv_node
directly, which is less roundabout. Sub-property access won't work
anymore, though.
Remove the seekable-start/-end fields as well, as they're redundant with
the ranges.
All this would normally be considered an API change, but since it's been
only a few days with no known users, change it immediately.
This adds some node.c helpers as well, as the code would be too damn
fugly otherwise.
Seems like most code dealing with this was for setting it in redundant
cases. Now SEEK_BACKWARD is redundant, and SEEK_FORWARD is the odd one
out.
Also fix that SEEK_FORWARD was not correctly unset in try_seek_cache().
In demux_mkv_seek(), make the arbitrary decision that a video stream is
not required for the subtitle prefetch logic to be active. We might want
subtitles with long duration even with audio only playback, or if the
file is used as external subtitle.
This improves upon the previous commit, and partially rewrites it (and
other code). It does:
- disable the seeking within cache by default, and add an option to
control it
- mess with the buffer estimation reporting code, which will most likely
lead to funny regressions even if the new features are not enabled
- add a back buffer to the packet cache
- enhance the seek code so you can seek into the back buffer
- unnecessarily change a bunch of other stuff for no reason
- fuck up everything and vomit ponies and rainbows
This should actually be pretty usable. One thing we should add are some
properties to report the proper buffer state. Then the OSC could show a
nice buffer range. Also configuration of the buffers could be made
simpler. Once this has been tested enough, it can be enabled by default,
and might replace the stream cache's byte ringbuffer.
In addition it may or may not be possible to keep other buffer ranges
when seeking outside of the current range, but that would be much more
complex.
This was phased out, and was used only by vdpau by now. Drop the
mechanism and the vdpau special code, which means screenshots won't
include the vf_vdpaupp processing anymore. (I don't care enough about
vdpau, it's on its way out.)

Rename --stats to --load-stats-overlay and add an entry to options.rst
over the original commit.

Previously multiple timers were used to realize oneshot, toggling
(redrawing) and page keybindings. The oneshot case in particular also
relied on mp.osd_message to display text only for a given duration.
This was changed to only use one timer in total now. Because now each
case has a defined "start" and "end" point (including oneshot)
mp.set_osd_ass() can be used to print stats as well. This is currently
optional and has to be activated using the config option
persistent_overlay=true.
One shortcoming: oneshot and toggling are mutual exclusive right now.
Previously you could enter toggling while oneshot stats were shown,
this is not possible anymore to reduce the number of cases to be
considered. This can be added later on if desired.
It used a bad heuristic that got even worse/less reliable with recent
changes in mpv. In fact, it's not reliable at all.
Watch out for dropped frames instead. That's a useful indicator.
Previously I could trigger a bug with intense button mashing, however,
was unable to reproduce it and therefore debug it.
This change now seems to be resilient against button mashing, let's hope
it really is.
Please note that the latest version of this script needs a very recent
version of mpv (from yesterday, to be precise, see the readme).
For older versions, please go to "releases".
HOW IT WORKS:
While the stats are visible (i.e. text is printed to the OSD) a
subsequent click on a numeric key (1, 2, ...) will display the
corresponding "page".
This works no matter if the stats are toggled or just shown as a single
invocation. In case of a single invocation, the newly displayed page
will be shown for the full duration again.
The selected page will be remembered (not persistantly though).
So far, only 3 pages are available.
1: the default page, stats as they used to be
2: extensive VO performance stats (to be redesigned/changed soon)
3: dummy
In the future, many more pages are possible.
Implementation is likely to change again (functionality will stay
the same). A new timer had to be introduced to remove the forced
keybindings in the oneshot case. The toggle case can remove them without
a timer. Ensuring that each mode won't remove timers of the other mode
didn't really turn out neat.
Therefore, I intend to change this again, maybe by merging the
oneshot case into the toggle case.
Due to the large amount of per-pass data, the function takes a parameter
indicating whether or not to print a simplified view instead.
The overall intent is to print the simplified view for now, but supposed
printing the full view on a dedicated "tab" (or extra view type), and as
such, `o.print_perfdata_passes` will go away again. I've only introduced
it for now so users can play around with this functionality if they want
to, until Argon- gets around to implementing stats "tabs".
Previously, we used a property and when it was unavailable we assumed it
doesn't exist before assuming it really is just unavailable. This lead
to unnecessarily falling back to deprecated properties which made mpv
print deprecation warnings.
Now we can really check if a property is not known to mpv.
The alternative would've been to check the error part of mp.get_property
and perform string comparisons on the returned error message.
Not sure if supporting old mpv versions is actually worth it though.
