* audio: don't allow setting unknown formats from command linewm42013-08-261-17/+1
| | | | | | | af_str2fmt_short(), which is used by the command line option parser, allowed passing a hex number. The user could set arbitrary integers as internal audio formats, even formats which don't exist or make no sense. This is not very useful, so get rid of it.
* audio: make internal audio format 0 an invalid formatwm42013-08-261-1/+1
| | | | | | | | | | | | Having to use -1 for that is generally quite annoying. Audio formats are created from bitmasks, and it can't be excluded that 0 is not a valid format. Fix this by adjusting AF_FORMAT_I so that it is never 0. Along with AF_FORMAT_F and the special formats, all valid formats are covered and guaranteed to be non-0. It's possible that this commit will cause some regressions, as the check for invalid audio formats changes a bit.

* core: add a spsc ringbuffer implementationStefano Pigozzi2013-06-161-0/+10
| | | | | | | | | | | | | | | | | Currently every single AO was implementing it's own ringbuffer, many times with slightly different semantics. This is an attempt to fix the problem. I stole some good ideas from ao_portaudio's ringbuffer and went from there. The main difference is this one stores wpos and rpos which are absolute positions in an "infinite" buffer. To find the actual position for writing / reading just apply modulo size. The producer only modifies wpos while the consumer only modifies rpos. This makes it pretty easy to reason about and make the operations thread safe by using barriers (thread safety is guaranteed only in the Single-Producer/Single- Consumer case). Also adapted ao_coreaudio to use this ringbuffer.
* audio: add double sample formatwm42013-05-121-11/+5
| | | | | | To make this easier, get rid of the direct mapping of the AF_FORMAT_BITS_MASK bit field to number of bytes. This way we can throw away the unused AF_FORMAT_48BIT and don't have to add ..._56BIT.
* audio: add some setters for mp_audio, and require filters to use themwm42013-05-121-0/+2
| | | | | | | | | | | | | | | | mp_audio has some redundant fields. Setters like mp_audio_set_format() initialize these properly. Also move the mp_audio struct to a the file audio.c. We can remove a mysterious line of code from af.c: in.format |= af_bits2fmt(in.bps * 8); I'm not sure if this was ever actually needed, or if it was some kind of "make it work" quick-fix that works against the way things were supposed to work. All filters etc. now set the format correctly, so if there ever was a need for this code, it's definitely gone.
* audio: remove support for native alaw/mulaw/adpcm outputwm42012-12-111-3/+0
| | | | | | This is considered a worthless feature. Note that alaw/mulaw/adpcm input is unaffected: such data is handed to libavcodec and "decoded" to linear PCM.
* Rename directories, move files (step 2 of 2)wm42012-11-121-1/+1
| | | | | | | | | | | | Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)
* Rename directories, move files (step 1 of 2) (does not compile)wm42012-11-121-0/+134
Tis drops the silly lib prefixes, and attempts to organize the tree in a more logical way. Make the top-level directory less cluttered as well. Renames the following directories: libaf -> audio/filter libao2 -> audio/out libvo -> video/out libmpdemux -> demux Split libmpcodecs: vf* -> video/filter vd*, dec_video.* -> video/decode mp_image*, img_format*, ... -> video/ ad*, dec_audio.* -> audio/decode libaf/format.* is moved to audio/ - this is similar to how mp_image.* is located in video/. Move most top-level .c/.h files to core. (talloc.c/.h is left on top- level, because it's external.) Park some of the more annoying files in compat/. Some of these are relicts from the time mplayer used ffmpeg internals. sub/ is not split, because it's too much of a mess (subtitle code is mixed with OSD display and rendering). Maybe the organization of core is not ideal: it mixes playback core (like mplayer.c) and utility helpers (like bstr.c/h). Should the need arise, the playback core will be moved somewhere else, while core contains all helper and common code.
