This was once central, but now it's almost unused. Only vf_divtc still
uses it for extremely weird and incomprehensible reasons. The use in
stream.c is trivial. Replace these, and remove mpbswap.h.

stream_cdda's output format is linked to demux_raw's default audio
format, and at least we don't care enough to provide a separate
mechanism to let stream_cdda explicitly set the format, so they must
match.
Judging from the existing code, it looks like CDDA always outputs little
endian. stream_cdda.c changed this back to native endian (what demux_raw
expects). Just make them both little endian. This requires less code,
and also having a raw demuxer's behavior depend on the endianness of the
machine isn't very sane anyway.

See previous commits. This finally replaces directly reading the file
data into a struct with reading them manually. In theory this is more
portable (no alignment issues and other things). For the most part,
it's nice seeing this gone.

Same as with the previous commit. A bit more involved due to how the
code is written.

MPlayer traditionally did this because it made sense: the most important
formats (avi, asf/wmv) used Microsoft formats, and many important
decoders (win32 binary codecs) also did. But the world has changed, and
I've always wanted to get rid of this thing from the codebase.
demux_mkv.c internally still uses it, because, guess what, Matroska has
a VfW muxing mode, which uses these data structures natively.
|
| |
|
|
|
|
|
|
| |
Let codec_tags.c do the messy mapping.
In theory we could simplify further by makign demux_mkv.c directly use
codec names instead of the MPlayer-inherited "internal FourCC" business,
but I'd rather not touch this - it would just break things.

For a while, we used this to transfer PCM from demuxer to the filter
chain. We had a special "codec" that mapped what MPlayer used to do
(MPlayer passes the AF sample format over an extra field to ad_pcm,
which specially interprets it).
Do this by providing a mp_set_pcm_codec() function, which describes a
sample format in a generic way, and sets the appropriate demuxer header
fields so that libavcodec interprets it correctly. We use the fact that
libavcodec has separate PCM decoders for each format. These are
systematically named, so we can easily map them.
This has the advantage that we can change the audio filter chain as we
like, without losing features from the "rawaudio" demuxer. In fact, this
commit also gets rid of the audio filter chain formats completely.
Instead have an explicit list of PCM formats. (We could even just have
the user pass libavcodec PCM decoder names directly, but that would be
annoying in other ways.)

Digital pass-through was probably broken. Possibly fix it (no way to
test). This also should make the logic slightly saner.
Fortunately, it's unlikely that anyone who uses OSS has a spdif setup.

Commit 5b5a3d0c broke this. The really funny thing is that this code was
actually always under "#if BYTE_ORDER == BIG_ENDIAN". The breaking
commit just edited this code slightly, but it must have failed to
compile on big endian long before (since over 1 year ago, commit d3fb58).

Oops.

Should be able to pass-through AC3, DTS, and others.
It seems PulseAudio wants players to fallback to PCM on certain events
signaled by the server, but we don't implement that. There's not much
documentation available anyway.
|
| |
|
|
|
| |
This works similar to condition variables; for some reason this
apparently worked fine until now, but it breaks with passthrough mode.
|
| |
|
|

Needed for compressed audio pass-through later.

Before this commit, there was AF_FORMAT_AC3 (the original spdif format,
used for AC3 and DTS core), and AF_FORMAT_IEC61937 (used for AC3, DTS
and DTS-HD), which was handled as some sort of superset for
AF_FORMAT_AC3. There also was AF_FORMAT_MPEG2, which used
IEC61937-framing, but still was handled as something "separate".
Technically, all of them are pretty similar, but may use different
bitrates. Since digital passthrough pretends to be PCM (just with
special headers that wrap digital packets), this is easily detectable by
the higher samplerate or higher number of channels, so I don't know why
you'd need a separate "class" of sample formats (AF_FORMAT_AC3 vs.
AF_FORMAT_IEC61937) to distinguish them. Actually, this whole thing is
just a mess.
Simplify this by handling all these formats the same way.
AF_FORMAT_IS_IEC61937() now returns 1 for all spdif formats (even MP3).
All AOs just accept all spdif formats now - whether that works or not is
not really clear (seems inconsistent due to earlier attempts to make
DTS-HD work). But on the other hand, enabling spdif requires manual user
interaction, so it doesn't matter much if initialization fails in
slightly less graceful ways if it can't work at all.
At a later point, we will support passthrough with ao_pulse. It seems
the PulseAudio API wants to know the codec type (or maybe not - feeding
it DTS while telling it it's AC3 works), add separate formats for each
codecs. While this reminds of the earlier chaos, it's stricter, and most
code just uses AF_FORMAT_IS_IEC61937().
Also, modify AF_FORMAT_TYPE_MASK (renamed from AF_FORMAT_POINT_MASK) to
include special formats, so that it always describes the fundamental
sample format type. This also ensures valid AF formats are never 0 (this
was probably broken in one of the earlier commits from today).

This code tried to play with the format bits, and potentially could
create invalid formats, or reinterpret obscure formats in unexpected
ways.
Also there was an abort() call if the winapi or mpv used a format with
unexpected bit-width. This could probably easily happen; for example,
mpv supports at least one 64 bit format. And what would happen on 8 bit
formats anyway?
Untested.

Until now, the audio chain could handle both little endian and big
endian formats. This actually doesn't make much sense, since the audio
API and the HW will most likely prefer native formats. Or at the very
least, it should be trivial for audio drivers to do the byte swapping
themselves.
From now on, the audio chain contains native-endian formats only. All
AOs and some filters are adjusted. af_convertsignendian.c is now wrongly
named, but the filter name is adjusted. In some cases, the audio
infrastructure was reused on the demuxer side, but that is relatively
easy to rectify.
This is a quite intrusive and radical change. It's possible that it will
break some things (especially if they're obscure or not Linux), so watch
out for regressions. It's probably still better to do it the bulldozer
way, since slow transition and researching foreign platforms would take
a lot of time and effort.

IEC 61937 frames should always be little endian (little endian 16 bit
words). I don't see any apparent need why the audio chain should handle
swapped-endian formats.
It could be that some audio outputs might want them (especially on big
endian architectures). On the other hand, it's not clear how that works
on these architectures, and it's not even known whether the current code
works on big endian at all. If something should break, and it should
turn out that swapped-endian spdif is needed on any platform/AO,
swapping still could be done in-place within the affected AO, and
there's no need for the additional complexity in the rest of the player.
Note that af_lavcac3enc outputs big endian spdif frames for unknown
reasons. Normally, the resulting data is just pulled through an auto-
inserted conversion filter and turned into little endian. Maybe this was
done as a trick so that the code didn't have to byte-swap the actual
audio frame. In any case, just make it output little endian frames.
All of this is untested, because I have no receiver hardware.

Until now, we always required the playback core to decode a new frame to
get more output from the filter. That seems to be completely
unnecessary, because filtered results may arrive before that.
Add a filter_out callback, and restructure the code such that it can
return any filtered frames, or block if it hasn't read at least one
frame.
In the worst case, it still can happen that bursts of input requests and
output requests happen. (This commit tries to reduce burst-like
behavior, but it's not entirely possible due to the indeterministic
nature of VS threading.)
This is a similar change as with 95bb0bb6.

E.g. --loop-file=2 will play the file 3 times (one time normally, and 2
repeats).
Minor syntax issue: "--loop-file 5" won't work, you have to use
"--loop-file=5". This is because "--loop-file" still has to work for
compatibility, so the "old" syntax with a space between option name and
value can't work.

libavcodec/libavformat now handles gapless audio better. In theory, this
could be implemented with ad_mpg123 too, but since libavformat strips
metadata from mp3 files and passes pure mp3 packets to the decoders
only, this can't work by itself. Instead, the player must pass this
metadata separately. libav* do this relatively transparently over packet
"side data" (attached to AVPacket).
It might also be possible to let libmpg123 handles all this by
implementing it as demuxer that outputs PCM, but that would have other
problems, and I think it's better to make libavformat work correctly.
libmpg123 can still be used with '--ad=mpg123:mp3'.
Also see issue #1101.

More consistent with other output, such as the terminal status line.

We generally want 2 things:
1. minimal wakeups for decoding each frame
2. minimal number of frames decoded on continuous seeking
Commit 35810cb8 changed this a bit, and fixed 1. But it broke 2., and
now it decodes 2 frames instead of 1 when you keep seeking (arrow key
held down or such). This made seeking appear slower.
Fix this by making the logic more explicit. In particular, call the
filters only if we actually try to get a new frame.
When playing with --no-audio and all other distractions disabled (like
OSC), it still wakes up 2 times per frame - but the second time is
merely because the VO didn't accept the new frame yet.
|
| |
|
|
|

|

It didn't actually disable it.
I'm actually not sure what this option is useful for, but fixing it
can't harm.

Be less annoying, print the actual OSD level instead of something
meaningless, but still clear the OSD if OSD level 0 (no OSD) is set.
Remove the special handling for terminal OSD, that was just dumb.

This means that if a property not listed in property_osd_display[] is
changed, it will be shown on the OSD as "name: ${name}".
Properties that are listed in property_osd_display[] and have osd_name
not set stay invisible by default. This is used for "pause" and
"fullscreen", which (like before this commit) are not shown by default,
because it would be annoying.
The defaults still can be changed with command prefixes (osd-msg,
no-osd, others).

Probably not many user-visible changes. One notable change is that the
terminal OSD code for OSD bar fallback handling is removed with no
replacement. Instead, terminal OSD gets the same text message as normal
OSD. For volume, this is ok, because the text message is reasonable.
Other properties will look worse, but could be adjusted, and there are
in fact no other such properties that would be useful in audio-only
mode.
The fallback message for seeking falls away as well, but that message
was useless anyway - the terminal status line provides all information
anyway.
I believe the show_property_osd() code is now much easier to follow.
|

If no VO was open, these options couldn't be changed or even queried.
Although these properties are nearly useless if no VO exists, there's
actually no good reason to forbid querying or setting them. Also, even
if the VO is created, it doesn't mean the VO window was created.
|
| |
|
|
|
|
|
|
| |
Why bother?
Also, since now some properties could be mapped to non-existing options,
but mp_property_generic_option() is used, deal with this case and return
a not-found error code.

If there's a command that uses the OSD by default, then always print the
associated message (or a fallback made of name + value), even if the
command has an associated OSD bar.
This means volume, gamma, panscan, etc. all show both a message and a
OSD bar.
Also, add a '%' to the volume message. The extra_msg thing is not needed
anymore.
See issue #1103.

It's just confusing; users are encouraged to edit input.conf instead
(changing the argument to the "add" command).
Update input.conf to keep the old behavior.
|

|

|

Make the note about quoting more prominent.
Add a warning that this filter is useless for new files.

When pausing after a frame was just dropped, we're logically at the
dropped frame, and thus should redraw the dropped frame. This was
implemented, but didn't work after unpausing for the second time,
because of a minor logic bug.

For incomprehensible reasons, AV_PIX_FMT_GRAY8 (and some others) have a
palette. This literally makes no sense and this issue has bitten us
before, but it is how it is.
This also caused a crash with vo_direct3d: this mapped a texture as
IMGFMT_Y8 (i.e. AV_PIX_FMT_GRAY8), and when copying this, it tried to
copy the non-existent palette.
Fixes #1113.

vo_vdpau uses its own framedrop code, mostly for historic reasons. It
has some tricky heuristics, of which I'm not sure how they work, or if
they have any effect at all, but in any case, I want to keep this code
for now. One day it might get fully ported to the vo.c framedrop code,
or just removed.
But improve its interaction with the user-visible framedrop controls.
Make --framedrop actually enable and disable the vo_vdpau framedrop
code, and increment the number of dropped frames correctly.
The code path for other VOs should be equivalent. The vo_vdpau behavior
should, except for the improvements mentioned above, be mostly
equivalent as well. One minor change is that frames "shown" during
preemption are always count as dropped.
Remove the statement from the manpage that vo_vdpau is the default; this
hasn't been the case for a while.

vc->vsync_interval and vsync_interval should be the same value, but
actually vc->vsync_interval was updated after vsync_interval was
initialized. This was probably not intended. Fix this by removing the
duplicate local variable. There were probably no bad effects.
