sdpmessage: fix mapping single char fmtp params
This fixes mapping of single character parameters from SDP to caps as discussed here: gst-plugins-rs!626 (comment 1218849)
E.g. for following a=fmtp:110 raptor-scheme-id=1; Kmax=8192; T=128; P=A; repair-window=200000 the caps will miss T and P
- Before patch:
caps: application/x-rtp, media=(string)application, payload=(int)110, clock-rate=(int)90000, encoding-name=(string)RAPTORFEC, raptor-scheme-id=(string)1, kmax=(string)8192, repair-window=(string)200000- After patch:
caps: application/x-rtp, media=(string)application, payload=(int)110, clock-rate=(int)90000, encoding-name=(string)RAPTORFEC, raptor-scheme-id=(string)1, kmax=(string)8192, t=(string)128, p=(string)A, repair-window=(string)200000To reproduce try following launch line (sdp file attatched below):
