Does SRS ingest support streams other than RTSP?

[fwang-umd]

Hello, I'm learning how to use SRS Ingest, it seems that RTSP stream worked, e.g.:
input {
type stream;
url rtsp://807e9439d5ca.entrypoint.cloud.wowza.com:1935/app-rC94792j/068b9c9a_stream2;
}

But if I replaced url with a valid RTMP or HTTP-FLV stream, it didn't work, I got lots of errors similar with this one:
drop unknown header video, size=1054, bytes[0]=0x22

Any advice?

Thank you,
Frank
