High memory usage on unix server

[nereikianieko]

I have a Centos server with 1Gb RAM, VLC is not specially compilled (maybe I should disable some modules), but VLC memory usage is huge - one idle instance with telnet interface takes about 100Mb, On unix simple streaming without transcoding takes about 230Mb of RAM
On windows the exact proccess without transcoding takes only ~40Mb of RAM .

I'm starting vlc with
vlc --extraintf telnet --telnet-port 5555 --telnet-password mypassword

Later I add command via telnet:
new MYSTREAM broadcast enabled setup MYSTREAM input "http://myip:8666" setup MYSTREAM output #std{access=http,mux=ts,dst=:8666}

And starting mystream with
control MYSTREAM play

I'm running each stream via separate process.

After running it, I receive these lines

Maybe it's n

[Rémi Denis-Courmont]

It sounds a lot like you are not comparing the same figure on both operating systems.

Transcoding takes a lot of memory. No surprises there. Something's got to store the raw decoded video frames.

[nereikianieko]

Sorry, maybe it was not clear: both machines, windows and unix,are not transcoding, are launched by exact parameters 1:1 (same job, same stream, same interfaces) but unix takes 5 times more RAM

[Rémi Denis-Courmont]

Because Unix does not measure memory the same way.
