That error message is definitely not coming from our software. However, if you are referring specifically to the “profile-level-id” value that the “LIVE555 Proxy Server” (or our non-proxying RTSP server) puts in the SDP descriptor that it gives to ‘front-end’ clients, then that is generated, by “H264VideoRTPSink”, by analyzing the SPS NAL unit that it was given. (By definition, the H.264 “profile-level-id” is defined by bytes 1,2,3 of the SPS NAL unit (after removing any ‘emulation’ bytes).) So, the “profile-level-id” that our software generates is correct; it comes from the input stream. If, however, your web browser can’t handle that, then that’s a problem for your web browser, or (perhaps) whatever gateway you are using between our RTSP server and your web browser. Again, this has nothing to do with our software, or this mailing list.
