I am not sure, but it looks like for given mode AMR and AMR-WB files have fixed frame size. "The length of the speech frame is implicitly defined by the mode indicated in the FT field": https://tools.ietf.org/html/rfc4867#page-35 Anyway, it is strange that mod_native_file registers AMR and AMR-WB formats if it could not support them. 2017-08-23 0:21 GMT+03:00 Anthony Minessale <anthony.minessale@gmail.com>:
The question was answered by the log line you supplied.
-- "cannot play or record native files with variable length data".
VBR codecs are not a predictable size so you cannot make a raw file of it because you don't have any idea how big each packet is.
