[vlc-devel] rtsp : start-time fails in demuxer

[Sébastien Escudier]

Hi

I would like to report a problem in start-time option with rtsp.
I have a test file (created with mp4 muxer, the only one where seeking works)
where start-time option works well locally (cf 1- at end of this mail).
But with rtsp it fails (short output here, cf 2- at end of this mail for more
output) :
