15/12/17VoipSwitch Latest Updated Transcoding Module includes:. Route and connect calls with no common audio codecs.
Transcoding is a process of converting one voice codec to another. For example, transcoding iLBC-G.711 or iLBC-G.729. Note: In every transcoding operation, media flows through CUBE. LTI based Transcoding. Internal API is used to access Digital Signaling Processor (DSP) resources for transcoding.
Fully transparent process. Increased transcoding capacity.
Supported voice codecs: G711u, G711a, G729 and AMR The updated transcoding feature enables VoipSwitch users to route and connect calls even when the call origination and termination have no common audio codec. The transcoding process is fully transparent for calling clients. It is performed by the VoipBox module which can also be installed on multiple additional servers to increase the capacity of transcoding calls concurrently. A single transcoding module can handle up to 200 calls on one 4core Xeon CPU server and supports a cluster architecture. Clients without access to their server hardware (e.g. A hosted server) may find this solution of interest, to install a hardware codec converter.If the server has excess resources, the calls transcoding feature can be resold to other providers as an additional service. The final price includes configuration on the client server by VoipSwitch support.
VoipBox requirements:. CPU: Intel XEON E5430 @ 2.66 GHz (4 core). OS: Windows 2008 server 64-bit. Network: 100 Mbps. RAM: 4GB. Milroy`s Disease Diet.VoipSwitch Inc.

I am messing around with an transcoding tutorial (source: )I am using FFmpeg 4.0.5 and built it successfully as follows:$ sudo apt-get install libx264-dev$ cd ffmpeg-4.0.5$./configure -prefix=buildout -enable-shared -disable-static -disable-doc -enable-gpl -disable-opencl -enable-libx264$ make$ sudo make install$ sudo ldconfigI have been looking at an article as well for guidance. The transcoding.c source file does compile:$ gcc transcoding.c -o out -lavformat -lavcodec -lavutil -lavfilterCalling the executable is straight-forward:$./out $INPUTVIDEO $OUTPUTVIDEOwhere $INPUTVIDEO is an mp4 container (h264/aac)Up until this point everything appears to be working on my Debian 10 VM (if that is relevant). However, I get the following erroneous output:h264v4l2m2m @ 0x564f664eebc0 Could not find a valid deviceh264v4l2m2m @ 0x564f664eebc0 can't configure encoderCannot open video encoder for stream #0Error occurred: Invalid argumentThe article I attached says I need to add it when compiling FFmpeg, so I changed the./configure line to as above, but to no avail. Any help or guidance would be appreciated.
