[MMUSIC] RTSP: Range response when PLAY request fails
Hi,
This is for discussing the following RTSP 2.0 issue raised by Christian
Haas:
https://sourceforge.net/tracker2/?func=detail&aid=2038457&group_id=23194&atid=377744
The issue is the following text in Section 13.4.1:
Server MUST include a "Range" header in any PLAY response.
So what is returned when the response becomes "457 Invalid range" when
playing? Please clarify this.
My suggestion for a fix is the following.
The first pargraph is already exist, the second is added:
Server MUST include a "Range" header in any PLAY response. The response
MUST use the same format as the request's range header contained. If no
Range header was in the request, the format used in any previous PLAY
request within the session SHOULD be used. If no format has been
indicated in a previous request the server MAY use any time format
supported by the media and indicated in the Accept-Ranges header in the
SETUP respone. It is RECOMMENDED that NPT is used if supported by the
media.
For any error response to a PLAY request, the server's response depends
on the current session state. If the session is in ready state, the
current pause-point is returned. For time-progressing content where the
pause-point moves with real-time due to limited retention, the current
resume point is returned. For sessions in playing state, the current
playout point and the remaining parts of the range request is returned.
Cheers
