Until recently, ao_lavc and vo_lavc started encoding whenever the core
happened to send them data. Since audio and video are not initialized at
the same time, and the muxer was not necessarily opened when the first
encoder started to produce data, the resulting packets were put into a
queue. As soon as the muxer was opened, the queue was flushed.
Change this to make the core wait with sending data until all encoders
are initialized. This has the advantage that we don't need to queue up
the packets.
The user won't want to have those in the video (I think). The core can
sporadically issue redraws, which is what you want for actual playback,
but not in encode mode. vo_lavc can explicitly detect those and skip
them. It only requires switching to a more advanced internal VO API.
The comments in vo.h are because vo_lavc draws to one of the images in
order to render OSD. This is OK, but might come as a surprise to whoever
calls draw_frame, so document it. (Current callers are OK with it.)
The video timing code could just decide that EOF was reached before it
was displayed. This is not really a problem for normal playback (if you
use something like --keep-open it'd show the last frame anyway,
otherwise it'd at best flash it on screen before destroying the window).
But in encode mode, it really matters, and makes the difference between
having one frame more or less in the output file.
Fix this by waiting for the VO before starting the real EOF.
vo_is_ready_for_frame() is normally used to determine when the VO frame
queue has enough space to send a new frame. Since the VO frame queue is
currently at most 1 frame, it being signaled means the remaining frame
was consumed and thus sent to the VO driver. If it returns false, it
will wake up the playloop as soon as the state changes.
I also considered using vo_still_displaying(), but it's not reliable,
because it checks the realtime of the frame end display time.
While I'm not sure whether it really works, at least it writes the pass1
log correctly now.
How 2-pass stat output is supposed to interact with the new decode API
is rather fishy. ffmpeg.c does the same, and before this change, the
log was not written on EOF (when at least libvpx actually outputs its
stats).
With the internal change from stringlist to keyvaluelist, these
sub-options stop working. I don't really care enough to bring them
back. (Order doesn't matter, -del always seemed annoying.)
Inspired by kmscube, first try to pick the Encoder and CRTC already
associated with the selected Connector, if any. Otherwise try to find
the first matching encoder & CRTC like before.
The previous behavior had problems when using atomic
modesetting (crtc_setup_atomic) when we picked an Encoder & CRTC that
was currently being used by the fbcon together with another Encoder.
drmModeSetCrtc was able to "steal" the CRTC in this case, but using
atomic modesetting we do not seem to get this behavior automatically.
This should also improve behavior somewhat when run on a multi screen
setup with regards to deinit and VT switching (still sometimes you end
up with a blank screen where you previously had a cloned display of
your fbcon)
Add some properties which where forgotten in crtc_setup_atomic.
In both change to not use DRM_MODE_PAGE_FLIP_EVENT | DRM_MODE_ATOMIC_NONBLOCK
flags. This should make it more similar to the drmSetCrtc which it aims to
replace (take effect directly, and blocking call). This also saves us the
trouble of having to set up a poll to wait for pageflip, which would've been
neccesary with DRM_MODE_PAGE_FLIP_EVENT, in both crtc_setup_atomic and
crtc_release_atomic.
This patch will make sure that the video plane is hidden when unused.
When using high resolution modes, typically UHD, and embedding mpv,
having the video plane sitting in the back when you don't play any video
is eating a lot of memory bandwidth for compositing.
That patch makes sure that the video layer is just disabled before and
after playback.
This commit allows to add atomic modesetting when using the atomic renderer.
This is actually needed when using and osd with a smaller size than screen resolution.
It will also make the drm atomic path more consistent
We are currently using primary / overlay planes drm objects, assuming that primary plane is osd and overlay plane is video.
This commit is doing two things :
- replace the primary / overlay planes members with osd and video planes member without the assumption
- Add two more options to determine which one of the primary / overlay is associated to osd / video.
- It will default osd to overlay and video to primary if unspecified
This patch adds
- DRM connector object to atomic context.
- fd property to the drm atomic object as well as a method to read blob type properties.
This allows to ensure that the proper connector is picked up, especially when specifying it
from the commandline, and also allows to make sure we're using the right one when embedding
with interop into an application.
That new API was introduced and allows to have several native resources.
Thisuses that mechanisma for drm resources rather than the deprecated
opengl-cb structs.
This patch therefore add two structs that can be used with the drm atomic interop.
- mpv_opengl_drm_params : which will hold all the drm handles
- mpv_opengl_drm_osd_size : which will hold osd layer size
This commit adds a drm-osd-size=WxH parameter to commandline which
allows to define the OSD plane dimension. OSD can be upscaled to
screen resolution when having OSD at video resolution is too heavy.
This is especially useful for UHD modes on embedded devices where
the GPU cannot handle UHD modes at a decent framerate.
It was documented for --screenshot-template, but apparently never
implemented.
This value is not explicitly rounded, other than for printf() %f default
formatting (which rounds to 6 digits).
This means that a time of 4.5678 is displayed as "00:00:04.568" when the
format string is "%H:%M:%S.%T". Likewise, 59.99999 will be displayed as
"00:01:00.000". Before this change, the sub-ms times were just
truncated.
Requested by TheAMM.
Define a hard-coded value for gl_NumWorkGroups if it is not available.
This adds an additional requirement of needing a shader recompile for
all window size changes.
This was considered a worthwhile compromise as currently f.ex. d3d11
completely lacked any peak computation - this is a major quality of
life upgrade.
Instead of using an internal counter to keep track of the value that was
set last, attempt to find the current value of the property/option in
the value list, and then set the next value in the list.
There are some potential problems. If a property refuses to accept a
specific value, the cycle-values command will fail, and start from the
same position again. It can't know that it's supposed to skip the next
value. The same can happen to properties which behave "strangely", such
as the "aspect" property, which will return the current aspect if you
write "-1" to it. As a consequence, cycle-values can appear to get
"stuck".
I still think the new behavior is what users expect more, and which is
generally more useful. We won't restore the ability to get the old
behavior, unless we decide to revert this commit entirely.
Fixes#5772, and hopefully other complaints.
If playback has not been initialized yet (decoders not initialized
etc.), or if in idle mode, let the track properties cycle through "no"
and "auto". This should be slightly more helpful than making it simply
exit.
Depending on the stage of loading, more could be done. For example, if
youtube-dl loads additional subtitle files, it can happen that these get
added before the main file, and this could be cycled through to an
extent. This is probably too clever, and also sort of dangerous
(unintended interactions with messy in-loading state), so don't do it.
AVFilterContext instances support some additional AVOptions over the
actual filter. This includes useful options like "threads". We didn't
support setting those for the "direct" wrapper (--vf=yadif:threads=1
failed). Change this. It requires setting options on the AVFilterContext
directly, except the code for positional parameters still needs to
access the actual filter's AVOptions.
Strictly speaking redundant, but probably helpful.
In particular I want to push MPV_RENDER_PARAM_ADVANCED_CONTROL. Not
enabling this parameter is actually not very sane.
This is for working around bugs in certain Android devices. At least one
device fails to sort EGLConfigs by size, so eglChooseConfig() ends up
choosing a config with 5/6/5 bits per r/g/b component. The other
attributes in the affected EGLConfigs did not look like they should
affect the sorting process as specified by the EGL 1.4 standard.
The device was reported as:
Sony Xperia Z3 Tablet Compact
Firmware 6.0.1 build number 23.5.A.1.291
GL_VERSION='OpenGL ES 3.0 V@140.0 AU@ (GIT@I741a3d36ca)'
GL_VENDOR='Qualcomm'
GL_RENDERER='Adreno (TM) 330'
Other Qualcom/Adreno devices have been reported as unaffected by this
(including some with same GL_RENDERER string).
"Fix" this by always requiring at least 8 bit. This means it would fail
on devices which cannot provide this. We're fine with this.
mpv-android/mpv-android#112
This was supposed to be a replacement for encode_lavc_discontinuity()
(so we don't need to store last_video_in_pts in a way which requires
synchronization). Unfortunately, VOCTRL_RESET is also called before
termination, and even though it shouldn't matter as far as the VO API is
concerned, it does. It's because vo_lavc.c buffers a frame to compute
the frame duration.
Drop this code. The consequence is that it appears to encode 2 frames
with the same PTS if multiple files are encoded into one. Before this,
it merely dropped a frame (maybe the first of every subsequent file, not
sure).
With -v -v ("debug" level), which is the default for --log-file, this
would log every damn Matroska EBML element and some other uninteresting
things, which was very noisy.
Adjust the log levels to make them less noisy. Also, change some log
calls to MP_ERR for things which are actually errors.
Sometimes this hints that there's a bug, but sometimes it's normal.
Since the code for --end/--frames puts frames that should not be shown
anymore back into the pin, using those options will show this warning
when playback ends. This is a minor annoyance. We could change how it's
done (e.g. set an explicit flag somewhere), but that seems bothersome,
so just change the message from warning to verbose.
The main change is that we wait with opening the muxer ("writing
headers") until we have data from all streams. This fixes race
conditions at init due to broken assumptions in the old code.
This also changes a lot of other stuff. I found and fixed a few API
violations (often things for which better mechanisms were invented, and
the old ones are not valid anymore). I try to get away from the public
mutex and shared fields in encode_lavc_context. For now it's still
needed for some timestamp-related fields, but most are gone. It also
removes some bad code duplication between audio and video paths.
1. I want to get away from mp_image_params (maybe).
2. For encoding mode, it's convenient to get the nominal_fps, which is
a mp_image field, and not in mp_image_params.
Removes a good hunk of weird code.
This loses qscale "emulation", some logging, and the fact that duplicate
keys for values starting with +/- were added with AV_DICT_APPEND. I
don't assign those any importance, even if they are user-visible
changes.
The new M_OPT_ flag is just so that nothing weird happens for other
key-value options, which do not interpret a "help" key specially.
