* audio: drop "_NE"/"ne" suffix from audio formatswm42013-11-151-4/+4
| | | | | | You get the native format by not appending any suffix to the format. This change includes user-facing names, e.g. for the --format option.
* audio/filter: fix mul/delay scale and valueswm42013-11-121-1/+0
| | | | | | | | | | | | | Before this commit, the af_instance->mul/delay values were in bytes. Using bytes is confusing for non-interleaved audio, so switch mul to samples, and delay to seconds. For delay, seconds are more intuitive than bytes or samples, because it's used for the latency calculation. We also might want to replace the delay mechanism with real PTS tracking inside the filter chain some time in the future, and PTS will also require time-adjustments to be done in seconds. For most filters, we just remove the redundant mul=1 initialization. (Setting this used to be required, but not anymore.)
* af: don't require filters to allocate af_instance->data, redo bufferswm42013-11-121-3/+1
| | | | | | | | | | | | | Allocate af_instance->data in generic code before filter initialization. Every filter needs af->data (since it contains the output configuration), so there's no reason why every filter should allocate and free it. Remove RESIZE_LOCAL_BUFFER(), and replace it with mp_audio_realloc_min(). Interestingly, most code becomes simpler, because the new function takes the size in samples, and not in bytes. There are larger change in af_scaletempo.c and af_lavcac3enc.c, because these had copied and modified versions of the RESIZE_LOCAL_BUFFER macro/function.
* audio/filter: prepare filter chain for non-interleaved audiowm42013-11-121-8/+9
| | | | | | | | | | | | | | | | | | Based on earlier work by Stefano Pigozzi. There are 2 changes: 1. Instead of mp_audio.audio, mp_audio.planes[0] must be used. 2. mp_audio.len used to contain the size of the audio in bytes. Now mp_audio.samples must be used. (Where 1 sample is the smallest unit of audio that covers all channels.) Also, some filters need changes to reject non-interleaved formats properly. Nothing uses the non-interleaved features yet, but this is needed so that things don't just break when doing so.
* af: replace macros with too generic nameswm42013-10-261-6/+7
| | | | | | | | Defining names like min, max etc. in an often used header is not really a good idea. Somewhat similar to MPlayer svn commit 36491, but don't use libavutil, because that typically causes us sorrow.
* audio/filter: remove useless af_info fieldswm42013-10-231-6/+4
| | | | | | | Drop the author and comment fields. They were completely unused - not even printed in verbose mode, just dead weight. Also use designated initializers and drop redundant flags.
* audio: add some setters for mp_audio, and require filters to use themwm42013-05-121-9/+4
| | | | | | | | | | | | | | | | 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.
* Rename af_volnorm to af_drcMartin2013-02-121-0/+353
The previous name of this filter was misleading, because it doesn’t actually normalize volume levels. What it does is closer to performing low-quality dynamic range compression, hence it is now called af_drc.
