2017-05-28prepare gapk for dealing with variable-length framesHarald Welte17-99/+191
The existing architecture was modelled around fixed-length codec frame sizes, which of course fails with multi-rate codecs such as AMR.
2017-05-28introduce #defines for canonical length + use themHarald Welte6-5/+10
2017-05-28Add ALSA input/output support to GAPKHarald Welte5-6/+214
The ALSA source/sink uses the pcm-s16le format.
2017-05-28RTP: give meaningful error messages if something failsHarald Welte1-8/+24
In fact, it should probably be better to silently ignore all those errors as opposed to aborting the entire processing queue? But that's for another patch...
2017-05-27add some more comments throughout the codeHarald Welte7-1/+53

2015-12-30libgsmhr: Make it safe to decode/encode different streams at onceSylvain Munaut2-0/+34
Basically the reference code has a bunch of global state. With some minimal patchihg (previous commit) we can ensure that all that state is within .bss So what we do it to save/restore the bss section between calls of the reference code so we can process several in // and we don't have to completely fix all reference to global state in the reference codec.

2015-12-30libgsmhr: Add some code cleanup / speedup patches for reference codecSylvain Munaut5-1/+388
Mostly this will help witht the upcoming bss switcheroo patch Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2015-12-30libgsmhr: Use patch instead of 'sed'Sylvain Munaut3-3/+552
Patches are without function-name and without context to minimize what we have to include. The current patchset does exactly what the previous 'sed' did, but this will make it easier to add more. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>

2014-05-08Add cycle benchmarking supportHarald Welte10-4/+310
This enables benchmarking of the codec. It will print the amount of CPU cycles needed for encoding/decoding a single 20ms frame on average.

2013-02-11gapk: make sure the output file is closed/flushed on ctrl+cHarald Welte1-1/+21
This is useful particularly in case you are reading from RTP and writing to a file, and don't want truncated codec frames in your file.
2013-02-11gapk: Add support for RTP input/output streamsHarald Welte5-13/+349
Instead of having only file-based I/O, this enables gapk to receive and send RTP streams, e.g. from live GSM network equipment like sysmoBTS/nanoBTS. Support is currently simplistic. On transmit, there is hard-coded codec type of full-rate GSM. On receive-side, we should auto-detect the format based on frame size and/or payload type, but we don't do that yet at all.
2013-02-11gapk main: move fh_in and fh_out to sub-structures in a unionHarald Welte1-16/+31
this is done in preparation to provide something else but file input/output.
