Errr,I heard of such a setting,CloudStalker,but,cough,cough,where is it and which values should I choose ?
Alright it's in: Preferences > (tab) Input / Codecs > (tab) Other codecs > FFmpeg > (check the "Advanced options" box at the bottom-right corner) and set the "Skip the loop filter for H.264 decoding" to "All" from the drop-list.
This is also what I am using and which works very effeciently. There are two further options: "hurry up" and "lowres" (values 0, 1 and 2 with 2 = strongest). They seem less effective but may also be useful since the full loop-filter skiping may considerably reduce qualite in some cases.
For those who are interested NOT to put these options permanently in the preferences: it is also possible to provide them in the command line such as:
vlc --ffmpeg-hurry-up --ffmpeg-lowres 2 --ffmpeg-skiploopfilter 4 rtsp://mafreebox.freebox.fr/freeboxtv/stream?id=617
(for NRJ12 HD for french unbundled customers of Free). I use in Linux a shell script "vlc_ecocpu.sh" containing:
vlc --ffmpeg-hurry-up --ffmpeg-lowres 2 --ffmpeg-skiploopfilter 4 $@
which may be called instead of vlc. I think this should also work with bat-scripts in Windows.
