i have pcap file which contains EVS codec data. I want to extract it from pcap file and make wav file with it.

i can find the voice data in pcap file, (it was norally 61,6 bytes) but i am not sure, if these data are the EVS codec data. I tried to write them to file and convert it with EVS codec https://github.com/ToughmanL/EVS_CODEC but it seems the structure is not same with EVS codec.

please help me to get wav file from pcap file.

The pcap can contain multiple concurrent streams and/or codecs, the command line can specify multiple pcaps, each stream can create child channels (per RFC8108). Output wav files are generated for each stream and optionally for "merged audio" of all streams.

.sdp files can be used to override codec auto-detection and/or select only specific streams

this tool has a Docker container and example pcaps
