Memory leak in HLS server #207

Closed tachang closed 3 years ago

tachang commented 3 years ago

I see things growing slowly eating more memory until it cannot allocate anymore memory. Is this a known issue?

Hi tachang,

This was introduced adapting to remove in live555 of TCPStreamSink, in commit https://github.com/mpromonet/v4l2rtspserver/commit/be67798772d00929c4af6b0b31f2bbea6d49c3b4. I will look at that.

Best Regards, Michel.

Thank you so much! This commit definitely solved the issue and memory is no longer growing unbounded.
