Questionable change from user perspective, but internally needed to
implement the next commit. Also useful for testing timeline stuff.

The problem with DVD/BD and playback resume is that most often, the
filename is just "dvd://", while the actual path to the DVD disk image
is given with --dvd-device. But playback resume works on the filename
only.
Add a pretty bad hack that includes the path to the disk image if the
filename starts with dvd://, and the same for BD respectively. (It's a
bad hack, but I want to go to bed, so here we go. I might revert or
improve it later, depending on user feedback.)
We have to cleanup the global variable mess around the dvd_device.
Ideally, this should go into MPOpts, but it isn't yet. Make the code
paths in mplayer.c take MPOpts anyway.

Apparently, it is popular to store large files in uncompressed rar
archives. Extracting files is not practical, and some media players
suport playing directly from uncompressed rar (at least VLC and some
DirectShow components).
Storing or accessing files this way is completely idiotic, but it is
a common practice, and the ones subjected to this practice can't do
much to change this (at least that's what I assume/hope). Also, it's
a feature request, so we say yes.
This code is mostly taken from VLC (commit f6e7240 from their git tree).
We also copy the way this is done: opening a rar file by itself yields
a playlist, which contains URLs to the actual entries in the rar file.
Compressed entries are simply skipped.

Add a stream filter concept, in which streams can be opened on top of
an underlying "source" stream. Change the open code to make this
easier, and also to account for some mechanisms that will be needed
for this.
The following commit will add stream_rar, which contains such a stream
filter.

The way the url_options field was handled was not entirely sane: it's
actually a flexible array member, so it points to garbage for streams
which do not initialize this member (it just points to the data right
after the struct, which is garbage in theory and practice). This was
not actually a problem, since the field is only used if priv_size is
set (due to how this stuff is used). But it doesn't allow setting
priv_size only, which might be useful in some cases.
Also, make the protocols array not a fixed size array. Most stream
implementations have only 1 protocol prefix, but stream_lavf.c has
over 10 (whitelists ffmpeg protocols). The high size of the fixed
size protocol array wastes space, and it is _still_ annoying to
add new prefixes to stream_lavf (have to bump the maximum length),
so make it arbitrary length.
The two changes (plus some more cosmetic changes) arte conflated into
one, because it was annoying going over all the stream implementations.

Modeled after the old playlist_parser.c, but actually new code, and it
works a bit differently.
Demuxers (and sometimes streams) are the component that should be used
to open files and to determine the file format. This was already done
for subtitles, but playlists still use a separate code path.

stream_file.c contains some code meant for forward seeking with pipes.
This simply reads data until the seek position is reached. Move this
code to stream.c. This stops stream_file from doing strange things
(messing with stream internals), and removes the code duplication too.
We also make stream_seek_long() use the new skip code. This is shorter
and much easier to follow than the old code, which basically did strange
things.

So for example "file:///file%20name.mkv" will open "file name.mkv".
I'm not sure whether we want/need this. The old code didn't do it.
Also, it's not really clear whether this is handled correctly. It
seems the corresponding freedesktop.org "standard" allows a (useless)
hostname part, which we should skip in theory. The number of slashes
is not really clear either. We can open relative filenames (by removing
one of the slashes from the example above), which is perhaps an
unneeded feature. How does this even work with Windows paths?
This issues can probably be corrected later.
The URL unescape code is based on code from m_option.c removed with
a recent commit.

Move the URL parsing code from m_option.c to stream.c, and simplify it
dramatically. This code originates from times when http code used this,
but now it's just relict from other stream implementations reusing this
code. Remove the unused bits and simplify the rest.
stream_vcd is insane, and the priv struct is different on every
platform, so drop the URL parsing. This means you can't specify a track
anymore, only the device. (Does anyone use stream_vcd? Not like this
couldn't be fixed, but it doesn't seem worth the effort, especially
because it'd require potentially touching platform specific code.)

These were printed only with -v. Most streams had them set to useless
or redundant values, so it's just badly maintained bloat.
Since we remove the "author" field too, and since this may have
copyright implications, we add the contents of the author fields to
the file headers, except if the name is already part of the file header.

Stream implementations could set this to a unix file descriptor. The
generic stream code could use it as fallback for a few things. This
was confusing and insane. In most cases, the stream implementations
defined all callbacks, so setting the fd member didn't have any
advantages, other than avoiding defining a private struct to store it.
It appears that even if the stream implementation used close() on the
fd (or something equivalent), stream.c would close() it a second time
(and on windows, even would call closesocket()), which should be proof
for the insanity of this code.
For stream_file.c, additionally make sure we don't close stdin or
stdout if "-" is used as filename.
For stream_vcd.c, remove the control() code. This code most likely
didn't make the slightest sense, because it used a different type
for stream->priv. It also leaked memory. Maybe it worked, but it's
incorrect and insignificant anyway, so kill it. This code was added
with commit 9521c19 (svn commit 31019).
Untested for all protocols other than stream_file.c.

This removes the dependency on DEMUXER_TYPE_* and the file_format
parameter from the stream open functions.
Remove some of the playlist handling code. It looks like this was
needed only for loading linked mov files with demux_mov (which was
removed long ago).
Delete a minor bit of dead network-related code from stream.c as well.

Add this option, which lets users set the cache size without forcing it
even when playing from the local filesystem.
Also document the default value explicitly.
The Matroska linked segments case is slightly simplified: they can
never come from network (mostly because it'd be insane, and we can't
even list files from network sources), so the cache will never be
enabled automatically.

This was an old leftover from an earlier cleanup (which happened in
2003), and which used "special" stuff for streams that could be only
forward-seeked.
Also, don't add mode flags to s->flags; they're supposed to be in
s->mode instead.

This commit removes the "old" networking code in favor of libavformat's
code.
The code was still used for mp_http, udp, ftp, cddb. http has been
mapped to libavformat's http support since approximately 6 months ago.
udp and ftp have support in ffmpeg (though ftp was added only last
month). cddb support is removed with this commit - it's probably not
important and rarely used if at all, so we don't care about it.

STREAM_CTRL_GET_METADATA will be used to poll for streamcast metadata.
Also add DEMUXER_CTRL_UPDATE_INFO, which could in theory be used by
demux_lavf.c. (Unfortunately, libavformat is too crappy to read metadata
mid-stream for mp3 or ogg, so we don't implement it.)

Seems like a completely unnecessary complication. Instead, always add a

Also add some documentation. There was some, but it was outdated and
incomplete.

This function was called in various places. Most time, it was used
before a seek. In other cases, the purpose was apparently resetting
the EOF flag. As far as I can see, this makes no sense anymore. At
least the stream_reset() calls paired with stream_seek() are completely
pointless. A seek will either seek inside the buffer (and reset the
EOF flag), or do an actual seek and reset all state.

Basically rewrite all the code supporting the cache (i.e. anything other
than the ringbuffer logic). The underlying design is untouched.
Note that the old cache2.c (on which this code is based) already had a
threading implementation. This was mostly unused on Linux, and had some
problems, such as using shared volatile variables for communication and
uninterruptible timeouts, instead of using locks for synchronization.
This commit does use proper locking, while still retaining the way the
old cache worked. It's basically a big refactor.
Simplify the code too. Since we don't need to copy stream ctrl args
anymore (we're always guaranteed a shared address space now), lots of
annoying code just goes away. Likewise, we don't need to care about
sector sizes. The cache uses the high-level stream API to read from
other streams, and sector sizes are handled transparently.

This is a nice way to avoid an additional copy of the data when reading
with stream_read().

demux_lavf probes up to 2 MB of data in the worst case. When the ffmpeg
demuxer is actually opened, the stream is seeked back to 0, and the
previously read data is thrown away.
This wasn't a problem for playback of local files, but it's less than
ideal for playing from slow media (like web streams), and breaks
completely if the media is not seekable (pipes, some web streams).
This new function is intended to allow fixing this. demux_lavf will use
it to put the read probe data back into the buffer.
The simplest way of implementing this function is by making it
transparently extend the normal stream buffer. This makes sure no
existing code is broken by new weird special cases. For simplicity
and to avoid possible performance loss due to extra dereferencing
when accessing the buffer, we just extend the static buffer from
8 KB to 2 MB. Normally, most of these 2 MB will stay uncommitted, so
there's no associated waste of memory. If demux_lavf really reads all
2 MB, the memory will be committed and stay unused, though.

Before this commit, the cache was franken-hacked on top of the stream
API. You had to use special functions (like cache_stream_fill_buffer()
instead of stream_fill_buffer()), which would access the stream in a
cached manner.
The whole idea about the previous design was that the cache runs in a
thread or in a forked process, while the cache awa functions made sure
the stream instance looked consistent to the user. If you used the
normal functions instead of the special ones while the cache was
running, you were out of luck.
Make it a bit more reasonable by turning the cache into a stream on its
own. This makes it behave exactly like a normal stream. The stream
callbacks call into the original (uncached) stream to do work. No
special cache functions or redirections are needed. The only different
thing about cache streams is that they are created by special functions,
instead of being part of the auto_open_streams[] array.
To make things simpler, remove the threading implementation, which was
messed into the code. The threading code could perhaps be kept, but I
don't really want to have to worry about this special case. A proper
threaded implementation will be added later.
Remove the cache enabling code from stream_radio.c. Since enabling the
cache involves replacing the old stream with a new one, the code as-is
can't be kept. It would be easily possible to enable the cache by
requesting a cache size (which is also much simpler). But nobody uses
stream_radio.c and I can't even test this thing, and the cache is
probably not really important for it either.

Some code in mplayer.c did stuff like accessing (dvd_priv_t *)st->priv.
Do this indirectly by introducing STREAM_CTRL_GET_DVD_INFO. This is
extremely specific to DVD, so it's not worth abstracting this further.
This is a preparation for turning the cache into an actual stream, which
simply wraps the cached stream. There are other streams which are
accessed in the way DVD was, at least TV/radio/DVB. We assume these
can't be used with the cache. The code doesn't look thread-safe or fork
aware.

Tests with demux_mkv show that the speed doesn't change (or actually,
it seems to be faster after this change). In any case, there is not
the slightest reason why these should be inline. Functions for which
this will (probably) actually matter, like stream_read_char, are
still left inline.
This was tested with demux_mkv's indexing. For broken files without
index, demux_mkv creates an on-the-fly index. If you seek to a later
part of the file, all data has to be read and parsed until the wanted
position is found. This means demux_mkv will do mostly I/O, calling
stream_read_char() and stream_read(). This should be the most I/O
intensive non-deprecated part of mpv that uses the stream interface.
(demux_lavf has its own buffering.)

Allow the stream layer to report chapter times. Extend stream_dvd to do
this. I'm not 100% sure whether the re-used code is bug-free (because it
was used for slave-mode and/or debugging only).
MAke the frontend do time-based seeks when switching DVD chapters. I'm
not sure if there's a real reason STREAM_CTRL_SEEK_TO_CHAPTER exists
(maybe/hopefully not), but we will see.
Note that querying chapter times in demuxer_chapter_time() with the new
STREAM_CTRL_GET_CHAPTER_TIME could be excessively slow, especially with
the cache enabled. The frontend likes to query chapter times very often.
Additionally, stream_dvd uses some sort of quadratic algorithm to list
times for all chapters. For this reason, we try to query all chapters on
start (after the demuxer is opened), and add the chapters to the demuxer
chapter list. demuxer_chapter_time() will get the time from that list,
instead of asking the stream layer over and over again.
This assumes stream_dvd knows the list of chapters at the start, and
also that the list of chapters never changes during playback. This
seems to be true, and the only exception, switching DVD titles, is not
supported at runtime (and doesn't need to be supported).
|
| |
|
|
|
|
| |
Will be needed to override the demuxer's start time reporting. We could
be lazy and special-case it since the result is always 0 for the streams
that care, but doing it properly is better.

DVD playback uses a demuxer that signals to the frontend that timestamp
resets are possible. This made the frontend calculate the OSD playback
position based on the byte position and the total size of the stream.
This actually broke DVD playback position display. Since DVD reports a
a linear playback position, we don't have to rely on the demuxer
reported position, so disable this functionality in case of DVD
playback. This reverts the OSD behavior with DVD to the old behavior.

This didn't work properly for HTTP with libavformat. The builtin HTTP
implementation reconnects automatically on its own, while libavformat
doesn't. Fix this by adding explicit reconnection support to
stream_lavf.c, which simply destroys and recreates the AVIO context.
It mostly works, though sometimes it mysteriously fails, spamming crap
all over the terminal and feeding broken data to the decoders. This is
probably due to itneractions with the cache. Also, reconnecting to
unseekable HTTP streams will make it read the entire stream until the
previous playback position is reached again.
It's not known whether this change makes behavior with "strange"
protocols like RTP better or worse.

This is a fix for web radio streams that send raw AAC [1]. libavformat's
AAC demuxer probe is picky enough to request hundreds of KBs data, which
makes for a slow startup. To speed up stream startup, try use the HTTP
MIME type to identify the format. The webstream in question sends an AAC
specific MIME type, for which demux_lavf will force the AAC demuxer,
without probing anything.
ffmpeg/ffplay do the same thing. Note that as of ffmpeg commit 76d851b,
av_probe_input_buffer() does the mapping from MIME type to demuxer. The
actual mapping is not publicly accessible, and can only be used by
calling that function. This will hopefully be rectified, and ideally
ffmpeg would provide a function like find_demuxer_from_mime_type().

Use ffmpeg (stream_lavf) instead of internal mms support (asf_streaming.c)
for mms://, mmsh://, mmst:// URLs.
The old implementation is available under mp_mms:// etc.
There are some caveats with this:
- mms:// now always maps to mmsh://. It won't try mmst://. (I'm not sure
if mms:// URLs really can use the mmst protocol, though.)
- MMS streams under the http:// prefix are not handled. (ffmpeg ticket
#2001.) (Was already broken in mpv since c02f25.)
- It downloads all video streams now. MMS streams often have redundant
video streams, which encode the main stream at different quality. The
client is supposed to select one according to its bandwidth
requirements. (Explicit MMS stream selection has been broken in mpv
for a while, because MPOpts.vid maps to the stream number, not the
demuxer's stream ID - but the old logic doesn't work anyway when
using demuxer_lavf as opposed to demux_asf.)
