vlc freezes at a fast forward speed of 16x

[T-buch]

I like to do many fast seeks of some of my video-files. The videoformat of those videofiles are in MPEG-TS, AVC 1280 x 720 pixels 50.000 FPS (and mpeg2 audio)

Everything is Fine with a speed of 8X - but when trying to increase the speed to 16X, the video freezes

I have done everything which is listed here https://windowsreport.com/vlc-media-pla ... indows-10/ - but the problem is still unsolved

Any ideas?

Do people understand the problem?

Hello,

at first glance this could be a device read bandwidth issue (storage device too slow ?).
Can you check:
- in VLC: error messages in message window (Ctrl-M shortcut, set verbosity to debug)
- in Task Manager -> Performance tab: check for the disk usage.

Hello and thanks for your reply

There are no problems with the disk Use - rather the the CPU speed of my I5 2500K - At a speed of 16X I got a CPU-usage og 55% and I got the following error message:
avcodec error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

Setting it to debug - I got:

Are you using VLC 2.2 ? If so please try VLC 3.0. With hardware decoding that might solve the issue.

[T-buch]

As I can see the newest official version is 2.x.x???
(anyhow thanks for the advice)

[T-buch]

Now I am using VLC 3.0
Unfortunately, I have to say that it only got worse
Things get unstable already at a speed of 4X - 8x
