Harald Welte 495c694781 print meaningful error messages if something goes wrong in main/pq 2017-05-28 14:30:05 +02:00
Harald Welte 8b01f0ca05 Add AMR codec support 
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

Harald Welte 5912848d2e prepare gapk for dealing with variable-length frames 
The existing architecture was modelled around fixed-length codec frame
sizes, which of course fails with multi-rate codecs such as AMR.

Harald Welte 07d691314c RTP: give meaningful error messages if something fails 
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...

Sylvain Munaut c0f0342596 libgsmhr: Make it safe to decode/encode different streams at once 
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.

Sylvain Munaut 59a6c2dc62 libgsmhr: Use patch instead of 'sed' 
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.

Harald Welte e7e12cc9aa gapk: make sure the output file is closed/flushed on ctrl+c 
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.

Harald Welte ce94d971e1 gapk: Add support for RTP input/output streams 
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.
