Remove the attempted cleverness; keep it dumb.
This strictly calculates the average speed over an at least 1 second
window (longer if I/O blocks it).
Since this doesn't reset the speed anymore when reading stops by going
idle, the results might actually be more accurate now.

Tuning it in a way to be actually useful is too much effort.
As alternative, there's the "buffering" detection, which operates on a
much higher level. The only disadvantage is that it's harder to guess
for the user whether this is a network problem, or if e.g. libavformat
is probing too much data when opening a stream. Maybe the cache-speed
property is helpful here.
For now, do not remove the associated code, but just silence the
warning.
Fixes #3019.

I got a report that the build on a recent aarch64 Linux kernel failed.
DVB support was detected, but errored on compilation:
In file included from ../stream/stream_dvb.c:57:0:
../stream/dvbin.h:72:5: error: unknown type name 'fe_bandwidth_t'
fe_bandwidth_t bw;
Make the test stricter, which should take care of this. (I couldn't find
out what exactly triggered the failure, nor could I attempt to reproduce
it.)
The change in stream/dvbin.h is to make sure that this isn't caused by
incorrect header inclusion. It now includes the same files as the
configure test.

Don't assume EOF if we didn't try to read anything in the first place.
Fixes regressions in particular with low cache sizes, which triggered
the other code paths more often.

Instead of having a separate for each, which also requires separate
additional caching in the demuxer. (The demuxer adds an indirection,
since STREAM_CTRLs are not thread-safe.)
Since this includes the cache speed, this should fix #3003.

Should reflect I/O speed.
This could go into the terminal status line. But I'm not sure how to put
it there, since it already uses too much space, so it's not there yet.

Ever since a change in mplayer2 or so, relative seeks were translated to
absolute seeks before sending them to the demuxer in most cases. The
only exception in current mpv is DVD seeking.
Remove the SEEK_ABSOLUTE flag; it's not the implied default. SEEK_FACTOR
is kept, because it's sometimes slightly useful for seeking in things
like transport streams. (And maybe mkv files without duration set?)
DVD seeking is terrible because DVD and libdvdnav are terrible, but
mostly because libdvdnav is terrible. libdvdnav does not expose seeking
with seek tables. (Although I know xbmc/kodi use an undocumented API
that is not declared in the headers by dladdr()ing it - I think the
function is dvdnav_jump_to_sector_by_time().) With the current mpv
policy if not giving a shit about DVD, just revert our half-working seek
hacks and always use dvdnav_time_search(). Relative seeking might get
stuck sometimes; in this case --hr-seek=always is recommended.

At least DTV_ENUM_DELSYS is not available in older versions.
It's hard to tell when this identifier was introduced, but it appears it
was probably API version 5.5.

May help in future debugging in case of old kernels
with modern / obscure devices.
|
| |
|
|
|
|
|
|
|
|
|
| |
Using the new API is a necessity for multiple-delivery-system
devices, since the old API does not offer a way to switch
the delivery system of the card.
This should in principle also be done for DVB-T / ATSC,
especially since most DVB-T devices also support DVB-C,
but I can not test such an implementation due to lack of hardware
(currently) so it seems better to leave the existing, tested code-path
in place for now.
|
| |
|
|
|
|
|
|
| |
No need use use all capital letters, and don't warn
if DVB-S2 is supported in addition since we handle that
in DVB-S case already.
Also, print the delivery system number for still unhandled
delivery systems to simplify debugging.
|
| |
|
|
|
|
|
|
|
| |
Saves one unnecessary additional ioctl per tuning
by just reusing existing information.
Should also fix the case of multiple supported delivery types
since we now rely on the initial query from the chosen
configuration after channel list parsing
instead of requerying the device.
|
| |
|
|
|
|
|
|
|
| |
Most common case would be DVB-C / DVB-T combination cards.
Cards with multiple delivery systems are only supported
starting from DVBv5 API (Kernel 2.6.38).
In this case, we loop over all delivery systems and
just treat them as different cards would be treated:
They all get their own TUNER-type, channel-list parsing etc.

This covers source files which were added in mplayer2 and mpv times
only, and where all code is covered by LGPL relicensing agreements.
There are probably more files to which this applies, but I'm being
conservative here.
A file named ao_sdl.c exists in MPlayer too, but the mpv one is a
complete rewrite, and was added some time after the original ao_sdl.c
was removed. The same applies to vo_sdl.c, for which the SDL2 API is
radically different in addition (MPlayer supports SDL 1.2 only).
common.c contains only code written by me. But common.h is a strange
case: although it originally was named mp_common.h and exists in MPlayer
too, by now it contains only definitions written by uau and me. The
exceptions are the CONTROL_ defines - thus not changing the license of
common.h yet.
codec_tags.c contained once large tables generated from MPlayer's
codecs.conf, but all of these tables were removed.
From demux_playlist.c I'm removing a code fragment from someone who was
not asked; this probably could be done later (see commit 15dccc37).
misc.c is a bit complicated to reason about (it was split off mplayer.c
and thus contains random functions out of this file), but actually all
functions have been added post-MPlayer. Except get_relative_time(),
which was written by uau, but looks similar to 3 different versions of
something similar in each of the Unix/win32/OSX timer source files. I'm
not sure what that means in regards to copyright, so I've just moved it
into another still-GPL source file for now.
screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but
they're all gone.

On read, it returns the name of the current DVB program,
on write, it triggers a channel-switch to the program
if it is found in the channel list of the currently active card.
Compared to the dvb-channel property which already exists
and is a pair of integers (card + channel number) this has the limitation
of not switching the card, but is probably of much more common use.

The mutex is used in dvbin_open and dvbin_close only since these are
the only entry / exit points to the stream.
When opening, it is first checked (mutexed) whether the state already exists
and is in use, then a STREAM_ERROR is returned,
since there may be only one stream_dvb active at a time.
State-creation itself is also protected by mutex.
In dvbin_close, the usage-bit is set to false (mutexed) in case
of channel switch.
In case of stream-teardown, the state is destructed
(also protected by mutex).
|
| |
|
|
| |
Now title will be the current channel name also after channel switch.
|
| |
|
|
|
|
|
|
|
| |
The state-structure is kept in a static pointer and reused on
recreation of the stream.
To not leak the state and the FDs within upon mpv shutdown,
the state-structure is still destructed gracefully in dvbin_close(),
unless a channel switch has been initiated directly before.
This fixes channel-switching for DVB which was broken since a609877.
|
| |
|
|
|
|
|
|
|
| |
The state-struct now contains everything which can be kept after initial initialization.
This includes the channel-lists, configuration, device-fds and also information like
current channel and current card.
The dvb_priv_t is kept containing the mp-options, a pointer to the state and to the logger.
After this restructuring, the state-struct contains all information which can be persisted
across channel switching.

Windows definitely supports Unix-style fd inheritance. This mostly
worked when launched from mpv.exe, though mpv should change the file
mode to O_BINARY. When launched from mpv.com, the wrapper must pass the
list of handles (stored in the undocumented lpReserved2 and cbReserved2
fields) to the mpv process.

This is only for specific Hauppage cards. According to the comments in
who is actively using this feature. Get it out of the way.
Anyone who still wants to use this should complain. Keeping this code
would not cause terribly much additional work, and it could be restored
again. (But not if the request comes months later.)

This commit introduces logic to read other volumes from the same source
as the primary archive. Both .rar formats as well as 7z are supported for now.
It also changes the libarchive callback structure to be per-volume
consistent with the libarchive intenal client data array constructed
with archive_read_append_callback_data.
Added open, close and switch callbacks. Only the latter is strictly
required to make sure that the streams always start at position 0, but
leaving all volumes open can eat a lot of memory for archives with many
parts.
|

"libarchive:" is already added by the logging system

See #2435. It's literally a waste of time trying to fix minor memory
leaks in this old, unused, and crappy code.

Don't print the URL that is opened twice. stream.c and stream_lavf.c
each printed it once. Remove the logging from stream_lavf.c, and move
the log call to a more interesting point.

This causes weirdness with the "cache-size" property and option. Only
the read handler of the property included the backbuffer, while all
others did not. Make it consistent, and subtract the backbuffer size
from the cache size.
Fixes #2305.

As expected, probing with libarchive is a disaster. Both libavformat and
libarchive are too eager to misdetect file formats just because files
"might" be of a specific type. In this case, it's mp3 vs. tar. To be
fair, neither file format has an actual header. I'm not sure why we'd
need tar support, but since libarchive provides it, and idiots on the
internet apparently pack media files in tar sometimes (really, idiots),
keep it for now, and probe tar last.
|
| |

Too many false positives (it accepts things like unspecific text files),
and also relatively useless.
|
| |
|
|
|
|
|
|
|
|
|

libarchive uses a quite confusing ifdeffery mess for some of the types
used in callbacks. Currently, archive_read_set_seek_callback() causes a
warning at least on Windows due to mismatching return type. The header
file uses __LA_INT64_T as return type, so I think the user is intended
to use int64_t.
(The ssize_t return type for the read_cb seems correct, on the other
hand.)
|
| |
|
|
|
| |
Most of what is not in this list is extremely obscure, or increases the
file format misdetection rate.
|
| |
|
|
|
| |
And use it everywhere, instead of retrieving the size manually. Slight
simplification.
|
| |
|
|
|
|
|
|
| |
Things like .gz etc., which have no real file header. A mixed bag,
because it e.g. tends to misdetect mp3 files as compressed files or
something (of course it has no mp3 support - I don't know as what it
detects them). But requested by someone (or maybe not, I'm not sure
how to interpret that).

This works similar to the existing .rar support, but uses libarchive.
libarchive supports a number of formats, including zip and (most of)
rar.
Unfortunately, seeking does not work too well. Most libarchive readers
do not support seeking, so it's emulated by skipping data until the
target position. On backwards seek, the file is reopened. This works
fine on a local machine (and if the file is not too large), but will
perform not so well over network connection.
This is disabled by default for now. One reason is that we try
libarchive on every file we open, before trying libavformat, and I'm not
sure if I trust libarchive that much yet. Another reason is that this
breaks multivolume rar support. While libarchive supports seeking in
rar, and (probably) supports multivolume archive, our support of
libarchive (probably) does not. I don't care about multivolume rar, but
vocal users do.
