Hi,
Sorry for the insufficient information.
I was running version 0.8.6.e on Windows XP. At the very beginning,
vlc.exe took up around 8MB memory space. It suddenly increased to 20MB after
I started playing. I was simply open a network stream from menu bar
File->Open network stream and assigned the port number to 3400 for UDP/RTP.
As time goes by, the memory took up by vlc.exe was increased to 38MB in 5
minutes. The video source was MPEG4 encoded stream encapsulated by MPEG2-TS
format and its bitrate was 1Mb.
And, I thought the memory was going to be freed up after the player
was stopped. However, it's not. It still took up 18MB. How come?
See below for more detail information.

Hi!
Thanks for your report.
You'll need to be a bit more specific though.
What interface are you using? what kind of stream do you read? Can you
run VLC in verbose mode (-vvv) and report the output here?
Pierre.
