* Relicense some non-MPlayer source files to LGPL 2.1 or laterwm42016-01-191-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* stream: provide a stream_get_size() convenience functionwm42015-08-181-2/+1
| | | | | And use it everywhere, instead of retrieving the size manually. Slight simplification.
* cache_file: refuse to cache unseekable streamswm42014-09-291-0/+5
| | | | | | | | | This makes no sense to use with DVD/BD/DVB and some others, and these streams happen to be unseekable. Also, other kinds of unseekable streams (like reading from pipe) should work, but will exhibit sketchy behavior if they need to seek. So just disable it, and leave these problems to the memory cache (cache.c).
* cache_file: add a mode that creates a temporary filewm42014-08-301-1/+2
| | | | | | | Since we have to be portable, our options for creating temporary files are somewhat limited. tmpfile() happens to be available everywhere, so use that. This function doesn't allow having a "visible" filename or location, so we use the magic string "TMP" for this.
* cache_file: fix operation if stream size is unknownwm42014-07-121-2/+3
| | | | | | | | | | | | | Happens when playing from a pipe. Note that seeking forward doesn't work. It would be possible to create a workaround for that by reading and skipping data until the target position is reached (and writing the skipped data into the cache file), but I'm not sure about that. Fixes #928. CC: @mpv-player/stable
* cache_file: use unicode on windowswm42014-07-021-0/+2
| | | | This enables the MinGW Windows crap wrapper for fopen().
* stream: add a file cachewm42014-06-221-0/+149
For remarks, pretty much see the manpage additions. Could help with network streams that require too much seeking (maybe), or might be extended to help with the use case of watching and downloading a file at the same time. In general, it might be a useless feature and could be removed again.
