On some DVDs, title number is not necessarily the same as the (first)
PGC number. (Most often they are equal, since there's usually exactly
one PGC per title, which is likely why this issue wasn't noticed
before.) When searching for audio/subtitle metadata, we want to look
at the actual PGC we're about to play. See discussion in issue #4235.

This reverts commit df91e492fd.
Multiple issues such as weird code with undefined behavior (like
(like conf_file*). The PR wasn't properly reviewed anyway (my error),
so this commit should be reviewed and then merged again.

This fixes a crash when changing channels; previously stream->priv would not
be initialized when dvb_get_state reused the existing state.

Because it's kind of dumb. (But not sure if it was worth the trouble.)
For stream_file.c, we add new explicit fields. The rest are rather
special uses and can be killed by comparing the stream impl. name.
The changes to DVD/BD/CD/TV are entirely untested.
"uncached_stream" is a pretty bad name. It could be mistaken for a
boolean, and then its meaning would be inverted. Rename it.
Also add a "caching" field, which signals that the stream is a cache or
reads from a cache. This is easier to understand and more flexible.
This is almost cosmetic, but removes the duplicated EOF-setting.
Somewhat oddly, this will enter the reconnect path and exit it
immediately again - should be fine.
Commit 7be495b3 added the cancellation test, but forgot to set the eof
flag. This could lead to demux_mkv.c not terminating if the stream was
cancelled in some code paths.
This function is what is supposed to set the EOF flag in the first
place, so just add the missing code.
Benefits demux_mkv.c, or demux_lavf.c during probing. In particular
demux_lavf.c can sometimes get "stuck" when reading from a slow/blocking
source, and if probing needs more than a few iterations.
Since this is a read of an atomic variable with relaxed semantics, this
should have no impact on reading speed at all, not even theoretically.
This was excessively useless, and I want my time back that was needed to
explain users why they don't want to use it.
It captured the byte stream only, and even for types of streams it was
designed for (like transport streams), it was rather questionable.
As part of the removal, un-inline demux_run_on_thread() (which has only
1 call-site now), and sort of reimplement --stream-dump to write the
data directly instead of using the removed capture code.
(--stream-dump is also very useless, and I struggled coming up with an
explanation for it in the manpage.)
Even though the title list code was copied from FFmpeg/libbluray,
I didn't check that mpv used 0-based title indexing.
$ mpv bd://1 --bluray-device=. --msg-level=bd=v
[bd] Opening bd://
[bd] List of available titles:
[bd] idx: 1 duration: 00:00:36 (playlist: 00000.mpls)
[bd] idx: 2 duration: 01:31:30 (playlist: 00001.mpls)
[bd] idx: 3 duration: 00:00:50 (playlist: 00003.mpls)
bd://1 actually opens idx 2 from the list, not 1.
bd://mpls/1 opens playlist 00001.mpls as expected.
With this commit:
$ mpv bd://1 --bluray-device=. --msg-level=bd=v
[bd] Opening bd://
[bd] List of available titles:
[bd] idx: 0 duration: 00:00:36 (playlist: 00000.mpls)
[bd] idx: 1 duration: 01:31:30 (playlist: 00001.mpls)
[bd] idx: 2 duration: 00:00:50 (playlist: 00003.mpls)
should play the expected idx 1.
This code used to check/free multiple things, so the argument to free()
was not always NULL. After the code was simplified, the free() became
redundant.
POSIX leaves poll() behavior on directories unspecified. While on
Linux, it seems to behave the same way as regular files (always
return immediately), this is not guaranteed. At least with OSX
10.12, it seems to wait, which essentially means that opening
directories will "hang".
Fixes#3530 and #3649.
AVIOContext.seekable is actually a bitfield. Currently, it has only
AVIO_SEEKABLE_NORMAL defined, but it might be extended with a hint for
non-byte seekability. Thus we should check it correctly.
demux_lavf.c forces seek to being determined as supported if
STREAM_CTRL_HAS_AVSEEK is returned as success. But it always succeeds
with current FFmpeg versions. (Seems like Libav commit cae448cf broke
this in early 2016.)
Now we can't determine via private API whether the underlying protocol
supports read_seek anymore. The affected protocols (mostly rtmp) also
set seekable=0, meaning they signal they're not seekable, even though
read_seek would work. (My guess is that this can't be fixed because even
though seekable is in theory a combination of elaborate flags [of which
only 1 is defined, AVIO_SEEKABLE_NORMAL], a seekable!=0 always means
it's byte-seekable in some way.)
So the FFmpeg API is being garbage _again_, and all what we can do is
determining this via protocol name and a whitelist.
Should fix the behavior reported in #1701.
There was both user-agent and user_agent options, the former is deprecated in FFmpeg/FFmpeg@27714b462 master.
Libav uses both forms.
This avoids constant `[ffmpeg] http: the user-agent option is deprecated, please use user_agent option` warnings using ytdl_hook.
--list-protocol was printing a *:// entry, which looked strange at best.
The "*" protocol was used to always match everything, so stream_cb.c
could hook in custom protocols with a prefix chosen by the API user.
Change it instead so that an empty protocol list means "match all",
which also gets rid of the special-cased "*" entry.
This has all been made unnecessary recently. The change not to copy the
global option struct in particular can be made because now nothing
accesses the global options anymore in the demux and stream layers.
Some code that was accidentally added/changed in commit 5e30e7a0 is also
removed, because it was simply committed accidentally, and was never
used.
Mostly untested.
This is not compatible. It removes the URL fields for track range and
cdrom speed (what did this even do). The device is not not to be
prefixed with an additional "/" if it's put into the URL. I can't be
bothered to keep these things compatible, just rip your damn CDs
instead.
Instead, parse manually. This is to get rid of the option API usages,
which seem unnecessary and shoehorned. (Just look at the URL pseudo
parsing and the dumb url_options map. They were pretty much artifacts
from refactoring old mplayer code.)
Don't access MPOpts directly, and always use the new m_config.h
functions for accessing them in a thread-safe way.
The goal is eventually removing the mpv_global.opts field, and the
demuxer/stream-layer specific hack that copies MPOpts to deal with
thread-safety issues.
This moves around a lot of options. For one, we often change the
physical storage location of options to make them more localized,
but these changes are not user-visible (or should not be). For
shared options on the other hand it's better to do messy direct
access, which is worrying as in that somehow renaming an option
or changing its type would break code reading them manually,
without causing a compilation error.
seek_fn is supposed to return the new file offset, or a negative error
code. Our code doesn't use the offset, and only wants to know if any
errors happened. The int cast is completely broken and might treat a
successful seek as failed depending on whether the sign bit will be set.
It's just wasted memory.
One corner case is when a file grows during playback, but this is rare
and usually happens on-disk only. The cache size was generally limited
before this change already, so no reason to care.
As an unrelated change, move the cache size info to the resize_cache()
function. There's really no reason not to do this, and it's slightly
more informative if the user changes the cache size at runtime.
If the normal stream cache init fails, and a file cache was initialized
before, we free the file cache as well. But since the file cache is
chained to the real stream, the real stream will also be freed. This has
to be prevented by clearing the pointer to the original stream in the
uncached_stream field.
This could in particular be triggered by using --cache-initial=1000 and
aborting playback during loading. (Without that option, stream cache
init failure is far less likely.)
Some client API users simply don't like such filenames. For their sake,
don't return them, but return a dummy filename instead. (Returning a
latin1-ized version would work too, but is slightly more work.)
Also remove the "\n" from the replacement dummy filename. This was
accidental.
The cache reader thread actually unlocks the mutex protecting the
underlying stream while reading from it. That's why other code goes out
of its way to run certain stream operations on the cache thread. Do the
same.
We could have this simpler by creating a mechanism that would "park" the
cache thread and make it wait for the lock (while we have it) in order
to gain exclusive access. This could be done in the future.
Eagerly execute seeks to the underlying stream in the cache seek
entrypoint itself. While asynchronous execution is a goal of the cache,
it doesn't matter too much for seeks. They always were executed within
the lock, so the reader was blocked anyway. It's not necessary to ensure
async. execution here either, because seeks are relatively rare, and the
demuxer can just stay blocked for a while.

For clang, it's enough to just put (void) around usages we are
intentionally ignoring the result of.
Since GCC does not seem to want to respect this decision, we are forced
to disable the warning globally.
