Unsupported audio formats: MP4A-LATM, Opus, G.726, fragmented AAC #14
Description
Since #6 the app plays L16, G.711 (PCMU/PCMA) and AAC (RFC 3640 mpeg4-generic, ADTS, raw AU). Still not supported, and dropped silently with one log line:
MP4A-LATM(RFC 6416)- Opus
- G.726
- AAC access units fragmented across several RTP packets (RFC 3640)

Done in #52: Opus, MP4A-LATM (out-of-band config,
cpresent=0) and AAC access units fragmented across RTP packets. Device-tested with Majestic: Opus, AAC and L16, with codec switching on the fly. Still unsupported: G.726 (not offered by Majestic Lite, so no test source yet) and LATM with in-band config (cpresent=1).compot-dev commentedon Oct 12, 2026
Closing.
Done in #52: Opus, MP4A-LATM with out-of-band config (
cpresent=0), and AAC access units fragmented across RTP packets. Device-tested with OpenIPC Majestic.Not supported, by decision:
.audio.codecset toopus,aacor PCM, the camera sendsopus,mpeg4-genericorL16. Third-party cameras that offer G.726 can almost always send G.711 (PCMA/PCMU) or AAC instead, and the app already plays those.cpresent=1). Majestic does not send LATM at all (its AAC ismpeg4-generic), and the out-of-band LATM variant is supported. Such streams are detected and played without sound, as before.If a camera turns up that can only send one of these, please open a new issue using the Device report template.
