Hi everybody,

I have a Sony HDR-SR11E Handycam with 10.2 Megapixel, 1080i FullHD, which is recording files in HD AVCHD m2ts file format.
When trying to play this files using VLC 1.0.5 the output is very juddering.

While the the Havdycam Utility AVHCD players and MS Media Player are fine.
Assuming that my system is fast enough to show this files due to the 2 players above that played the content well.

Any setting that needs to be adjusted in VLC to have this files played well?

Kind regards Agent

One addition to my problem.

In the meantime I´ve tried the vlc 1.1.0 git version mentioned here viewtopic.php?f=14&t=70424#p233585
and enabled GPU acceleration.
In addition I've tried the Iron Man II trainer mentioned in the post above, which is playing fine on my system with and without GPU acceleration.

But my Handycam files are still the same........

My sytem is a AMD Athlon 64 X2 Dual Core Processor 4800+ 2.40Ghz
with 4GB Ram running Windows 7 - 32bit
GPU is a dual Nvidea GeForce 7800 GTX running in SLI mode.

So I assume that the hardware should not be the bottleneck, even if it is not the most current one

Really looking for some help here, cause I cant belief that VLC cant play that kind of files.

Codec info from vlc:
H264 - MPEG-4 AVC (part10) (h264)
1920x1080
50 Frames

btw. the Audio in playing fine while the video output sucks.

Kind regards Agent

Please share a short sample of a problematic file. Use Megaupload or Rapidshare or any other similar file sharing site.

Hi Lotesdelere,

any news?

Hi,
You speak of "juddering" which may be what I call "jerky" (see my question on the "problems with Windows thread - pseudo: Kookaburra.) Personally I'm beginning to think the problem is Windows 7. Maybe VLC doesn't work well with Windows 7? On another computer I have XP and there the HD video is perfect. It's only on my Windows 7 computer that I get this slight jerkyness.

Hi Kookaburra,

I had exactly the same problems (before I moved to Win7) on the same system with XP SP3.
So what I can say for sure is that it is not related to Win 7 cause the exact same file looks the same on the same system either with XP or Win7.
Have you tried my sample on your system, or are you talking about other HD content?


And just to mention again, the content is played fine with the Sony Havdycam Utility AVHCD player (and with Windows Media Player as well) so the performance to play this file is there,
and it is o.k with this two other utilities, just VLC makes it what you called jerky

Well no problems so far for me to play this video with VLC 1.0.5.

However your file has a quite high bitrate (14.9 Mbps avg for the video) of 16 Mbps with some peaks at 18 Mbps. That plus the high resolution of 1920*1080 and if you use a deinterlacer all of that is very very CPU demanding and I'm afraid your Athlon @ 2.4 GHz is a bit weak whilst I have no problems with my Core2 @ 3 GHz.

EDIT:
Looks like I'm having troubles when using Yadif 2x as the deinterlacer, the video freezes. But it's playing fine when using the BOB deinterlacer. I'll forward this issue to the devs.

Hi Lotesdelere,

no matter what deinterlacer I use I always get this freezes. I´ve tried all that are available today also with 1.0.5 version of VLC
During the file is played in VLC my CPU does not go higher than 60% of use. If the CPU is the root cause I expected to see it on 100%.....?!
I still do not belive in CPU recources being the isse. Also because the two other Utils are playing this file fine without any issue.

Are there any other tweaks I can try to do else than changing the deinterlacer. I see there are many but If I now start to play with them without even knowing
what they really cause (yes I´m a rookie) it may become frustrating for me
So any tuning advices for an expert would be appreciated
Also the feedback you will get from DEV would be interressting, cause it looks like you have the same issues when switching to BOB interlacer.

Regards Agent.

Hi there,
I too am having the same issues.
CPU never goes above 65% but video is VERY jerky. Unwatchable.
My PC is a 2.8G Pentium D with a Radeon 5570 pcie. So should be fast enough. I'm using VLC1.0.5

The same PC plays the file perfect using GOM player, but GOM does not recognise the audio codec, so no sound.

My laptop plays the same file perfect (both sound and video) using VLC 1.0.3, so it's not the file.

Please please help..........

The file's Video is:
Type: Video
Original ID: 271
Codec: h264
Resolution: 1280x720
Display Resolution: 1280x720
Frame Rate:100

Type: Audio
Original ID: 321
Codec: mp4a
Language: English
Channels: Stereo
Sample Rate: 48000 Hz
AAC extension: SBR

1280x720 at 100 Hz is quite big actually. Please try with VLC 1.1, as the newer FFmpeg/avcodec got much improved h264 decoding optimizations

You are correct, that is quite large.
I did not know there was a version 1.1 out. I have downloaded it and it does seem to have mostly fixed the problem. Still not as smooth as my laptop but now watchable.

Many thanks.

Hi again.
I'm sorry, but I have to take it back, the picture has not been "smoothed" out enough to make it watchable. When fast moving scenes occur, it gets too pixelated. Too annoying...

Anyone watching this thread......?
In case there is: I should have also added the missing a lot of frames. CPU still only at 60%

As the one who started this thread, I´m also still having the same issues.
Keep my fingers crossed that a new version will fix it, cause this is the only reason why
I still have the MS Media Player installed on my system.
If VLC get this to play fine sometime it will be kicked off my system.
But so far it is still an issue for me as well.

After two hours with Sony tech support (which didn't help)
I found that VLC player has a "deinterlace" option in Menu->Video->Deinterlacing
This solved my Sony MTS format problems...

This worked.

Deinterlace, I used mode Bob and all my .m2ts files are playing without that 3 second glitchy annoyance.

Just wanted to say thanks! This has been affecting me for some time.
