Mystery DVR video file... need a player

[seabhcan]

(Not sure if this is the right place to post this...)

I have a DVR video file from an unknown recorder I need to play - and I'm hoping someone might recognise the format by the name and description, and suggest some player software that I could try.

The file is named like this: IMG0006505878.dvr

and its 20MB in size. I've downloaded and tried a bunch of different CCTV player software from various websites without success. (things like 'Divar backup player' and 'Cyberline DVR Reviewer')

ffplay can partly decode a blocky, garbled version, and possibly only the i-frames. Its some varient of a H264 codec, and its multi-channel (maybe 4?). Frame size is 720x288

All suggestions welcome.

Have you tried VLC?

All suggestions welcome.

If it's suitable for attaching here (it's a public forum) maybe some members could figure it out.
The filename isn't much to go on.

Can't share the file I'm afraid, but I get this is a long shot.

I asked CoPilot:

How to identify a propeirtery video file?
How can I play it?
He says:
Proprietary video files can be tricky since they often require specific software to play. Here’s how you can identify and play them:

### Identifying a Proprietary Video File
1. Check the File Extension – Some common proprietary formats include .XVC, .NVR, .TSK, .HK, .DW, .XME, .G46, .XVR, .264, and .57643dcd9a7-70db-4a1f-b0ae-981daa162054.
2. Use a File Identifier Tool – Websites like Kinesense Vid-ID can help identify the format and suggest compatible players.
3. Check Metadata – Tools like ffmpeg or MediaInfo can provide details about the codec and format.

### Playing a Proprietary Video File
1. Use Manufacturer-Specific Software – Many proprietary formats require software from the device manufacturer43dcd9a7-70db-4a1f-b0ae-981daa162054.
2. Try Universal Players – VLC Media Player or MPC-HC can sometimes play proprietary formats.
3. Convert the File – If playback fails, converting the file using ffmpeg or HandBrake may help.
4. Search for Codecs – Some formats need additional codec packs to be installed.

If you’re dealing with CCTV footage, you might need specialized forensic tools43dcd9a7-70db-4a1f-b0ae-981daa162054. Let me know if you need help with a specific format!

.dvr file​

A .dvr file is a video recording made with Media Center on a Windows computer.3 It can also refer to a proprietary video and audio file container format called DVR-MS (Microsoft Digital Video Recording), developed by Microsoft for storing TV content recorded by Windows Media Center Edition on Windows XP, Vista, and 7.25

For .dvr files created by Media Center, you can open them using various media players such as Windows Media Player, VLC Media Player, and CyberLink PowerDVD.54 However, if you encounter issues opening .dvr files, it might be due to the file being copy-protected or requiring specific software to interpret the file correctly.25

If you need to convert a .dvr file to a more widely supported format like MP4, you can use conversion tools such as CloudConvert or UniConverter.41 These tools allow you to adjust video resolution, quality, and file size during the conversion process.4

For .dvr files from DVR devices, you might need to use specific software provided by the manufacturer, such as the Lorex by FLIR video player application.8 Additionally, some DVR devices use .dav files, which can be played using the Lorex by FLIR video player application available for both PC and Mac.8

In summary, .dvr files can be opened with dedicated media players or converted to more accessible formats using conversion tools, depending on their origin and intended use.
