3.08 version, unfortunatelly didn"'t play my CCTV h264 files In your case that might be true. It is important to differentiate between problems here. What initially looks like a problem playing H264 files actually turned out, in my case, to be a problem playing W264 and Q264 files. My camera r...

Just to confirm that the latest version of VLC for Mac 3.0.8 DOES play H264 files which have been corrputed to the W264 and Q264 'format'. My godforsaken Qnap camera files are now playable - thank you VLC!

This thread has gone dead. I dont blame them, after all this is the fault of the camera manufacturer not VLC. However, it's disappointing that VLC for windows can view these files - I dont quite get why its so hard to apply this fix to the MAC .

Sorry John Baptiste - you may be correct but it is possible that that is not the correct bug track. According to bug #22208 the problem only exists when hardware decoding is turned on - and is fixed when hardware decoding is turned off. This is NOT the case with me. My VLC is unable to play Q264 fil...

thanks

Hi folks, I asked about this in January but the thread sort of died out: Why does VLC for windows play Q264 files but VLC for Mac will not? Q264 files are just H264 files (or so I read elsewhere on this forum). QNAP, the company who make my surveillance software save the files in this format, I assu...

Hi there,
The MAC version of VLC is still unable to play these H264 files. The PC version can play them.
Does anyone know what the status of this is and whether there is a plan to fix this for the Mac version at some point?

thanks, John

It's possible that this is due to limitations of the hardware decoder for specific files and does not affect all H264 content - this is the majority of all content played with VLC these days! To fix those special cases, we need sample files, which you can upload to https://streams.videolan.org/uplo...

Bearing in mind that this already seems to be what happens with VLC on PC. So, I guess Im wondering if you can implement this feature for MAC too?

Hi Ive just read that QNAP, the company who make the surveillance software I use, have messed around with the h264 header labels on the video saved from attached cameras. People there are saying that they have changed the label h.264 to q264 I don't know how this ties in with VLC (in my case) thinki...

Update:

Installed the 3.0.6 update to VLC
This update hasn't fixed the problem.

Also to confirm that InTheWings suggestion:
>> --demux=avformat
does not help me on High Sierra or Mojave.

thanks

>> --demux=avformat

thanks inthewings,
I have just tested this on mojave but it doesn't work for me. I will test on high sierra tomorrow.

Thanks for your help felix paul kuehne Ive uploade the following file: 2019-01-21 14-45-00~14-45-33.avi It's from a Sony SNC VB642D camera. I disabled hardware decoding as you advised and VLC can now play the files from my HIKVision camera but not from the Sony SNC (which is a much higher-end camera...

Hi Guys,
Really? Has nobody else noticed that VLC 3 for OSX (fails on both 10.13 high sierra and 10.14.2 mojave) doesn't play H264 video?
I didn't think my usage was so niche...

Bump. I have this problem too on OSX High Sierra 10.13.6 VLC 3.0.4 The videos are from 2 different CCTV cameras. They are H264 format saved with an .avi file extension. Changing the extension has no effect. Ive tried the suggestions elsewhere about setting the demuxer to H264 but VLC still doesn't w...
