Description

I'm using javacv-platform 1.5.8 to record rtmp stream of ip camera.(multi thread)

I set timeout param: grabber.setOption("rw_timeout", 5 * 1000_000 + ""); grabber.setOption("stimeout", 10 * 1000_000 + "");

problem: when rtmp stream is lost or not stable, grabFrame() get stuck for a long time (1 or 2 hours), and i don't know why.

Contributor guide

Research direction
Inspect the FFmpegFrameGrabber source code to understand how timeouts are applied. Trace the grabFrame() method to see where it blocks. Check if the timeout options are correctly forwarded to FFmpeg.
