2017-05-28print_help(): Fix formatting of help textHarald Welte1-4/+2
2017-05-28Add support for RTP with GSM-HR payload according to RFC5993Harald Welte4-1/+85
This is incompatible with the ETSI TS 101 318 format!
2017-05-28Add support for RTP with GSM-HR payload according to ETSI TS 101 318Harald Welte4-1/+68
2017-05-28Add "rtp-efr" format support for RTP payload according to RFC3551 4.5.9Harald Welte4-1/+78
The RTP EFR payload is a bit like the FR payload: one nibble magic marker, then followed by the actual codec bits. So we need to add/remove that magic marker and shift the remainder by one nibble.
2017-05-28Fix HR codec block sizesHarald Welte3-5/+4
The ETSI reference codec actually uses an array of 20/22 16bit values rather than a "canonical" format. The conversion is what fmt_hr_ref.c is doing. However, codec_hr.c must then subsequently not check for the canonical input/output sizes, but those specific to it.
2017-05-28Print some useful information while putting together the procqueueHarald Welte5-0/+13
2017-05-28print meaningful error messages if something goes wrong in main/pqHarald Welte3-10/+34
2017-05-28Add AMR codec supportHarald Welte8-2/+245
After merging this change, there is support for the AMR codec (by means of libopencore-amr, which is already used for EFR). In terms of gapk formats, we introdude * the "amr-opencore" format, which serves both as the canonical format, and as the input format to opencore-amrnb itself. * the "rtp-amr" format, which is the payload of RFC4867 octet-aligned mode You can use the following command for a real-time RTP playback for AMR frames: ./gapk -I 0.0.0.0/30000 -f rtp-amr -A default -g rawpcm-s16le
2017-05-28more API documentationHarald Welte3-0/+26
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...

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: 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>

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.
