I'm getting a SIGSEGV at ast_slinear_saturated_multiply at the line:351 res = (int) *input * *value; It's called from ast_frame_adjust_volume. The frame looks like: (gdb) print *f $6 = {frametype = AST_FRAME_VOICE, subclass = {integer = 100021, format = { id = AST_FORMAT_SLINEAR16, fattr = {format_attr = { 0<repeats 64 times>}, rtp_marker_bit = 0 '\000'}}}, datalen = 0, samples = 320, mallocd = 1, mallocd_hdr_len = 1076, offset = 64, src = 0x51623b0 "func_jitterbuffer interpolation", data = {ptr = 0x0, uint32 = 0, pad = "\000\000\000\000\000\000\000"}, delivery = { tv_sec = 1436290187, tv_usec = 304285}, frame_list = {next = 0x0}, flags = 0, ts = 0, len = 0, seqno = 0} so datalen is 0 and samples nonzero. ast_frame_adjust_volume, however, iterates over samples, not datalen. Is that correct? What does it mean to have a packet with a zero datalen anyway?
This is an interpolated frame from func_jitterbuffer. It's part of packet loss concealment. What scenario exposed this?
