Move most code from demux_mkv_fill_buffer() to read_next_block(). The
former is supposed to read raw blocks, while ..fill_buffer() reads
blocks and turns them into packets.
Somehow this was setup such that a BlockGroup can be incrementally
read (at least in theory). This makes no sense, as BlockGroup can
contain only one Block (despite its name). There's no need to read
this incrementally, and makes the code confusing for no gain.
Read all the BlockGroup sub-elements with a single function call,
without keeping global state for BlockGroup parsing.
The code for reading block data was duplicated. Move it into a function.
Instead of returning on error (possibly due to corrupt data) and
signalling EOF, continue by trying to find the next block. This makes
error handling slightly simpler too, because you don't have to care
about freeing the current block. We could still signal EOF in this case,
but trying to resync sounds better for dealing with corrupted files.
Matroska files prepared for streaming have clusters with unknown size.
These files are pretty rare, see e.g. test4.mkv from the official
Matroska test file collection.
The end positions of the current cluster and block were managed by
tracking their size and how much of them were read, instead of just
using the absolute end positions.
I'm not sure about the reasons why this code was originally written
this way. One obvious concern is reading from pipes and such, but the
stream layers hides this. stream_tell(s) works even when reading from
pipes. It's also a fast call, and doesn't involve the stream
implementation or syscalls. Keeping track of the cluster/block end is
simpler and there's no reason why this wouldn't work.
Incomplete files don't have a valid index, because the index is usually
located near the end of a file. In this case, an index is created on the
fly during demuxing, or when seeks are done.
This used a completely different code path, which leads to unnecessary
complications and code duplication. Use the normal index data structure
instead. The seeking code at the end of seek_creating_index() (in this
commit renamed to create_index_until()) is removed. The normal seek code
does the same thing instead.
This refactor makes the code easier to understand. Also corrects a bug that
caused the window to move to the left when the new size was bigger than the
visible frame.
I am aware this detection may occur too late, depending on other
settings, but at least it usually works and is portable.
Where the output fd can be changed, though, it'd be better to force a
similar behaviour via file descriptor use: use pipe:3 as output to FD 3,
and change the calling program to expect the stream on FD 3.
These require bleeding edge libass (latest git version), and will be
ignored otherwise.
I'm not sure about the blur factor and scaling. The ASS/VSFilter
semantics for blur scaling are a bad mess. Might require further
investigation.
The condition that checked whether the chapters are out of order and
should be sorted was inverted. This likely wasn't noticed in testing,
because even if the chapters are unsorted, if the last two chapters
were sorted, the rest got sorted too.
Instead of doing this silly check, always sort the chapters after
demuxer initialization. Also make sure the sort order is stable in case
chapter start times are the same (original_index check).
This option can be used to selectively reset settings when playing the
next file in the playlist (i.e. restore mplayer and mplayer2 behavior).
Might remove this option again should it turn out that nobody uses it.
Consider:
mpv --volume 10 file1.mkv file2.mkv
Before this commit, the volume was reset to 10 when playing file2.mkv.
This was inconsistent to most other options. E.g. --brightness is a
rather similar case.
In general, settings should never be reset when playing the next file,
unless the option was explicitly marked file-local. This commit
corrects the behavior of the --volume and --mute options.
File local --volume still works as expected:
mpv --{ --volume 10 file1.mkv file2.mkv --}
This sets the volume always to 10 on playback start.
Move the m_config_leave_file_local() call down so that the mixer code
in uninit_player() can set the option volume and mute variables without
overwriting the global option values.
Another subtle issue is that we don't want to set volume if there's no
need to, which is why the user_set_volume/mute fields are introduced.
This is important because setting the volume might change the system
volume depending on other options.
At least libsdl adds -mwindows to the cflags, which marks the .exe
binary as GUI application. This means the program detaches from the
console when started in cmd.exe, instead of showing the playback
status, receiving console input, and so on.
Append -mconsole to the linker command line to disable -mwindows.

Commit bc20f2c moved the variable default_max_pts_correction (which
backs the --mc option) to the MPOpts struct. The initializer was
forgotten when doing this, so it was left at 0. This disabled part of
the A/V sync mechanism. This was apparent when using ad_spdif (this
decoder has other A/V sync related problems, and thus triggers this
issue easily).
Closes#59.
ntddcdrm.h is no longer under the 'ddk' directory in MinGW-w64,
and since MPV focuses on it instead of the old MinGW32, there's no
reason to keep that dir prefix, as it stops VCD support from being
built at all for Windows.
No subtitle selected was supposed to disable the preroll logic
completely. However, the packet skipping logic was not properly enabled,
so the demuxer would still return subtitle packets from before the seek
target timecode. This shouldn't matter at all in practice, but fixing
this makes the code clearer.
Makes sure that seeking to a given time position shows the subtitle at
that position. This can fail if the subtitle packet is not close enough
to the seek target. Always enabled for hr-seeks, and can be manually
enabled for normal seeks with --mkv-subtitle-preroll.
This helps displaying subtitles correctly with ordered chapters. When
switching ordered chapter segments, a seek is performed. If the subtitle
is timed slightly before the start of the segment, it normally won't be
demuxed. This is a problem with all seeks, but in this case normal
playback is affected. Since switching segments always uses hr-seeks,
the code added by this commit is always active in this situation.
If no subtitles are selected or the subtitles come from an external
file, the demuxer should behave exactly as before this commit.
In the last cleanup round, this was accidentally changed from a store
option to int, and the option value was passed as flag value.
(Not that anyone needs/uses/cares about this option...)
Handle the severely broken headers QuickTime Streaming Server sends.
Instead of ending the header with \r\n\r\n it ends with
\r\n<4 byte MP3 header>\r\n.
And programs like wget just silently accept this without even
printing a warning!!

Note: see previous commit.
Support broken icy-metaint response from QuickTime Streaming Server.
The full version string is "QuickTime Streaming Server 6.1.0/532".
It sends a HTTP response header that contains an MP3 header!
Fixes bug #2133.

Note that in mpv, "http://" is mapped to ffmpeg currently, and this
code is unused by default.
Clean up ifdefs so they make sense even if none or multiple are defined.
Also choose Linux as fallback case instead of failing, this
allows the code to compile e.g. on Android.

Commit 546ae23 fixed aspect ratio if the DisplayWidth or DisplayHeight
elements were missing. However, some bogus files [1] can have these
elements present in the file, but set to 0. Use 1:1 pixel aspect for
such files.
