* demux, stream: remove old rar support in favor of libarchivewm42019-09-131-147/+0
| | | | | | The old rar code could do uncompressed rar, libarchive supports at least some rar compression algorithms. There is no need to keep the old rar code.
* stream_rar: update commentwm42015-03-291-4/+2
| | | | The stream filter non-sense was removed, which makes it much easier.
* player: refine rar:// playlist-safety handlingwm42015-03-021-4/+2
| | | | | | | | | | | | It was possible to make the player play local files by putting rar:// links into remote playlists, and some other potentially unsafe things. Redo the handling of it. Now the rar-redirector (the thing in demux_playlist.c) sets disable_safety, which makes the player open any playlist entries returned. This is fine, because it redirects to the same file anyway (just with different selection/interpretation of the contents). On the other hand, rar:// itself is now considered fully unsafe, which means that it is ignored if found in normal playlists.
* stream: remove stream filter conceptwm42015-02-271-2/+2
| | | | Unused since the previous commit. (Apparently it was a stupid idea.)
* stream_rar: treat rar files as playlistswm42015-02-271-73/+6
| | | | | | | | | | | | Refactors an older hack, which for some reason used a more complicated way. This generates the playlist representing the contents of the rar file in demux_playlist.c. The pseudo-demuxer could easily be separate from the the playlist parsers (and in fact there's almost no shared code), but I don't think this obscure feature deserves a separate file. Sample files created with: rar a -v20000k -m0 files.rar file1.mkv file1.mkv
* stream: get rid of remaining uses of the end_pos fieldwm42015-02-061-2/+10
| | | | | | | | Most things stopped using this field for better support of growing files. Go through the trouble to repalce the remaining uses, so it can be removed. Also move the "streaming" field; saves 4 bytes (wow!).
* stream: redo playback abort handlingwm42014-09-131-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mechanism originates from MPlayer's way of dealing with blocking network, but it's still useful. On opening and closing, mpv waits for network synchronously, and also some obscure commands and use-cases can lead to such blocking. In these situations, the stream is asynchronously forced to stop by "interrupting" it. The old design interrupting I/O was a bit broken: polling with a callback, instead of actively interrupting it. Change the direction of this. There is no callback anymore, and the player calls mp_cancel_trigger() to force the stream to return. libavformat (via stream_lavf.c) has the old broken design, and fixing it would require fixing libavformat, which won't happen so quickly. So we have to keep that part. But everything above the stream layer is prepared for a better design, and more sophisticated methods than mp_cancel_test() could be easily introduced. There's still one problem: commands are still run in the central playback loop, which we assume can block on I/O in the worst case. That's not a problem yet, because we simply mark some commands as being able to stop playback of the current file ("quit" etc.), so input.c could abort playback as soon as such a command is queued. But there are also commands abort playback only conditionally, and the logic for that is in the playback core and thus "unreachable". For example, "playlist_next" aborts playback only if there's a next file. We don't want it to always abort playback. As a quite ugly hack, abort playback only if at least 2 abort commands are queued - this pretty much happens only if the core is frozen and doesn't react to input.
* Add more constwm42014-06-111-1/+1
| | | | | | | While I'm not very fond of "const", it's important for declarations (it decides whether a symbol is emitted in a read-only or read/write section). Fix all these cases, so we have writeable global data only when we really need.
* stream: remove chaos related to writeable streamswm42014-05-241-5/+2
| | | | | | | | | | For some reason, we support writeable streams. (Only encoding uses that, and the use of it looks messy enough that I want to replace it with FILE or avio today.) It's a chaos: most streams do not actually check the mode parameter like they should. Simplify it, and let streams signal availability of write mode by setting a flag in the stream info struct.
* stream: don't use end_poswm42014-05-241-0/+2
| | | | | | | | | | | | | | | | | | | Stop using it in most places, and prefer STREAM_CTRL_GET_SIZE. The advantage is that always the correct size will be used. There can be no doubt anymore whether the end_pos value is outdated (as it happens often with files that are being downloaded). Some streams still use end_pos. They don't change size, and it's easier to emulate STREAM_CTRL_GET_SIZE using end_pos, instead of adding a STREAM_CTRL_GET_SIZE implementation to these streams. Make sure int64_t is always used for STREAM_CTRL_GET_SIZE (it was uint64_t before). Remove the seek flags mess, and replace them with a seekable flag. Every stream must set it consistently now, and an assertion in stream.c checks this. Don't distinguish between streams that can only be forward or backwards seeked, since we have no such stream types.
* stream: mp_msg conversionswm42013-12-211-2/+2
| | | | We also drop some slave mode stuff from stream_vcd.
* Split mpvcore/ into common/, misc/, bstr/wm42013-12-171-1/+1
* Move options/config related files from mpvcore/ to options/wm42013-12-171-1/+1
| | | | | | | | | Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.
* player: load external subs for uncompressed rar archiveswm42013-12-061-0/+12
| | | | | | | | | | | | Uncompressed rar archives can be transparently opened, but the filename the player doesn't have the direct filename (but something starting with rar://... instead). This will lead to external subtitles not being loaded. This doesn't handle multi-volume rar files, but in that cases just use the --autosub-match=fuzzy option. Fixes #397 on github.
* stream: add uncompressed rar supportwm42013-08-261-0/+198
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.
