squeezeplay rtmp module does not support "Extended timestamp" in type 0 messages. When the timestamp has value 0x00ffffff (16777215 ) there is an extra 4 bytes. When the "processRTMP (1004) don't support channels > 63" error message occurs showing invalid window size and chunksize it is because these are messages using extended timestamp and the extended timestamp field has been interpreted as the chunksize or window size.
