#2415 closed enhancement (fixed)

RTSP (and SDP) client timeout is hard-coded to 10 seconds

Summary of the bug:

The timeout while waiting for UDP packets in response to opening an RTSP url or SDP file is hard-coded to 10 seconds (the MAX_TIMEOUTS define in rtsp.c). This makes it impossible to decode RTP streams that are intermittently active. It would be good if the hard-coded time out was replaced either by a ?timeout=NNNNN construct, as for UDP reception, or by an AVOption.

The current behaviour is great for TCP-failover in case there is no UDP connectivity, but not good for receiving intermittent streams.

How to reproduce:

open any SDP file for which there are currently no incoming packets.

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.
