If you are having perfomance issues playing back these files, most likely due to a slower CPU, and are running windows then I would suggest using CoreAVC. www.coreavc.com
Please note this is a commercial product ($10.00 for standard edition). It is far superior in efficiency to other h264 codec/filters. I myself use it. (No this is not an advertisement). You can read a lot about CoreAVCs early developement at the doom9 forums.
If you have a slower system, CoreAVC is by far the best (And cheapest) way to enable h264 playback.
i am having some problem with playing the first episode of nanoha.
The video can be played just fine, but for some reasons, the sound is all screwed up as in all the characters voice, the music have weird tones etc.. =(
My come is quite decent 1.8 ghz duo core, and i am using k-lite codec to play the file. All other files works just fine.. anyone has this problem ??? and how can i fix it.
Thanks in advance
on the subject of video issues, has anyone who had problems with episodes 1-4 tried 5 and later and found it better? since episode 5, the encoder was limited to main profile h264 which should be a bit easier on the cpu. if so, i'll make v2's of those first ones for the batch which will be out after the season is finished.
the poor fella: k-lite isn't a codec, it is a codec pack, which is a very bad idea. You should only install codecs as needed, or use something like CCCP, which is well tested, installs/uninstalls cleanly and provides easy control over the filters used.
try using a different AAC decoder, but be sure to disable/uninstall your current one first.
@jss: As i don't have those files myself i can't try it but if you want to compare the performace of different encodes you could either watch the "Cpu Time" meter in the taskmanager, or underclock your cpu to simulate a slower system =). Either by using some standart slowdown-software, hardunderclocking via bios oder rctools if you have a cpu that supports on-the-fly reclocking ^_°. Even though i remember bitrate beeing the biggest factor with x264 playback speed.
@coreavc: For people who want to try it, PowerDVD7 installs CoreAVC =) which is the version i'm using atm. The pdvd i'm using is a 30DayTrial tho (which isn't over for me yet), which is why i don't know what happens to coreavc once the trial is over even if you don't deinstall pdvd.
I've used it myself and indeed it does use alot less cpu (compared to ffdshow/libavoc in mpc), but it still doesn't solve a strange issue that drops frames even at ~30% cpu utilysation. Causes the actual average fps to drop to 22 on a 23.9fps file =/, i can't see a difference tho ^.^.
