Playback of Hikvision H.265+ video?

[T-Halen]

I've got a Hikvision security camera that is recording video using H.265+ technology. When I download that video and try to view it using VLC (v3.0.7.1) I get a still image from that video, but the video itself isn't playing, even though the time stamp and progress bar at the bottom of the VLC window shows that it is.

H.265+ info from Hikvision: https://content.hikvision.com/en/core-technology/h.265-plus

Question, should VLC be able to play this video? If not, is this something the team is working on?

Thanks.

I applied all the latest Windows10Pro updates, uninstalled, and re-installed VLC (with a reset of prefs/settings/etc..)
Still no luck. Just a still image from the video while the VLC player thinks it's playing (time stamp counts up, progress bar moves)

Here is what the codec info screen looks like.



Any ideas?

Uninstalled the current version of VLC, and installed the 32bit v2.2.4, and found that it plays the H.265+ video just fine. So it's obviously a bug in the most recent version(s).

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com if it's too long.

Also upload a short sample of a problematic file to Zippyshare.com (200 MB max) or to WeTransfer.com and then post the link to the file here.

If needed cut it with DGsplit and read here about how to do it:

100 MB max should be enough.

Code: Select all

Frame rate : 10.350 FPS

VLC has troubles for playing low FPS videos, it's a known issue for a long time and still awaiting for a fix.
I've read it should be fixed later in VLC 4.

VLC 32bit v2.2.4 doesn't have any trouble playing that video, and the current version doesn't have trouble playing H.264 or H.265(no plus) videos of the same frame rate.

Actually, this is fixed in VLC 3.0.8 which will be released soon : https://git.videolan.org/?p=vlc/vlc-3.0.git;a=commit;h=7c351860333b60b3db08daea4afad0e8384425de

I have upgraded to the 3.0.8 release, and these videos still do not play in VLC.

Unfornately, this is problem with Threading changes in FFmpeg/avcodec decoder.
This provides high performance for HD+ content, but breaks with low frame rate because it adds way too much delay.

You can workaround for a single media:
- Disable audio --noaudio
- Increase --file-caching to add and extra 500ms (1000ms for example)
- Disable frame threading --avcodec-threads=1
you can also
- Use --low-delay if you use 4.0 master branch

Try and provide feedback on one of these

- Disable audio --noaudio [no change, still doesn't play]
- Increase --file-caching=500 [video plays fine]
- Disable frame threading --avcodec-threads=1 [video plays fine]
