How to get better performance when playing HD H.264

[Jean-Baptiste Kempf]

I think I have some problem with the video. I was using media player and the screen size was ok but when I am using VLC, the screen size become small and tried several time to enlarge it but failed. Can anyone tell me what to do? Oh, for your kind information, I have just started using VLC and it is only 15 days.

Sorry, this is totally unrelated to the current subject.

Reset your preferences.

I have latest vlc. can't loop clips as I could with avi files. All other picture quality is excellent. Totallt computer illiterate so apologies for that. Help would be much appreciate. File type is 720p mkv I think on Windows 7 Home Premium.

So if your computer is dying when decoding 1080p samples from H264, do the following.

• [...]
• Go to "FFmpeg"
• Put the "skip-filter for H264" to all

Didn't have a noticeable effect on my 720p H.264 videos.
Anything else I can do?
Thank you.

You could try GPU acceleration (providing your GPU is supported):
http://wiki.videolan.org/WindowsFAQ#H.2 ... s_too_slow

^ Note the option described is using the "Simple" preferences.

If that doesn't work/doesn't help you could try increasing the file caching value. To do this go to:
Tools >> Preferences... >> (Select "All" for "Show settings") >> Input / Codecs >> Access modules >> File

And raise the "Caching value (ms)". Press "Save" and try a video.

Cheers, Arite.

many thanks Arite, I'll give it a try

When I play H.264 files, I find that VLC freezes after around half a second.

I think my likely problem is down to using the onboard graphics from my motherboard (I'm using an ASUS P5KPL AM SE which uses Intel GMA3100 for graphics), but I wanted to check.

If it's not that, I've seen the suggestions being down to the size of each core on the processor, but I'm using a 3.47GHz SIngle core processor.

I've also tried changing the "Skip the loop filter for H.264 decoding" and "Use GPU acceleration" setting, and they make no difference either way.

Any ideas?

(PS thanks for developing VLC, it's such a fantastic piece of software)

I have a i7 4 cores processor at 3GHz with DDR3 memory and SATA drives. But I have a decent graphic card (Gigabyte GV R455D3-512I). With all this, I can't play a Blu Ray media without using PowerDVD 10. Maybe you will need some code review and optimization

Have you tried changing the video output module? What do the logs say (might be hard to see if as you said VLC crahes, but open the Messages window set verbosity to 2).

Arite.

[robeff1]

I wouldn't know how or what to change the video output module to, to be honest.

The first time I created the log it crashed my PC with a huge number of messages, then wouldn't let me reload VLC without reinstalling it. I cleared preferences and cache, so that I'm now running a clean default version of vlc 1.1.11 - h264 files still stop anything between a second and a frame after starting and the log is as follows:

avcodec error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

As I said above, I'm using a 3.47GHz SIngle core processor and onboard Intel GMA3100 graphics.

Use VLC 2.0-rc1, it will solve it.

[vampelle]

okay it seems to work with your change setting to ffmpeg to All, but than i notice the quality of the video goes down by minor but its play the movie smoothly for my 1080p movies.

As i dont want to lose the quality provide me other solution and cant you fix this error, as other player i had no problem and the quality is the same

[Arite]

The quality will go down as less filtering is going on in order to allow the video to play smoother.

You could try enabling GPU acceleration:

[vampelle]

the gpu acceleration is unavailable for me to click.

Hey hey

Follow instructions and now my HD videos are running smoothly - but there's no sound.

Thoughts? (in simpleton, please. not too tech savvy.)

(worth pointing out that originally, VLC wasn't playing sound and the videos were lagging badly. these instructions have fixed the video, but not the audio).

thanks guys

Use VLC 2.0-rc1, it will solve it.

that worked for me too, thx

[_fred_berg_]

I followed the instruction you gave,

Open the preferences
Tick advanced in the lower right corner
Go to "Input/Codec"
Go to "other codecs" subcategory
Go to "FFmpeg"
Put the "skip-filter for H264" to all
Restart VLC

But it seems not to work? am I doing something wrong perhaps miss something?

[_fred_berg_]

Go to "other codecs" subcategory
Cant "FFmpeg"?? Is it connected to the version? what version should be using?
