Hey there! I've had a reoccurring issue for quite some time now on a few different Linux distributions (Ubuntu, Solus, Manjaro etc.) and I'd like to ask if I'm doing something wrong, if this is a bug or some misconfiguration issue.

I'm trying to record from OBS (https://obsproject.com/) into H.264 .MP4 and edit the footage in DaVinci Resolve Beta 15.0b4. I've also had the same issue with versions <15. Using Nvidia GTX 960 w/ 4 GB VRAM and official Nvidia 390.59 drivers

My installation goes fine, DaVinci Resolve opens and everything seems perfect. I import my media and it shows up with "No Video". It cannot seem to import the video correctly and trying to edit the footage just shows a black, blank preview.

Recording of issue: (~1:30)

Image of issue:

I would love any help and I'd be happy with providing more debugging information on request. (A crash report was sent in the recording too)

Run log: https://pastebin.com/9bkw6Xci (I couldn't find a --debug flag or anything. Adding any flag seemed to cause a segmentation fault but it runs fine without any flag. https://pastebin.com/SQqhJBHR)

Thank you!

I'm having a similar issue on Ubuntu 18.04LTS. I have some Sony footage that was trimmed up in DaVinci Resolve on Windows 10 and output to H.264/mp4 video with audio. When imported to DaVinci Resolve Beta 15.0b4 on Ubuntu the audio is the only thing DaVinci Resolve sees. The audio play as expected but no video. VLC see the video and and audio so I'm assuming there is a lib missing for DaVinci Resolve. I used Daniel Tufvesson Debian package creator(Release 2018-04-27) to do the install of DaVinci Resolve 15.0b4.

Video files in an mp4 container using the H.264 codec are not supported in DaVinci Resolve on Linux. You need DaVinci Resolve Studio in order to playback those files. AAC audio is also unsupported. You need to use ffmpeg or other transcoder to convert the clips into a different container/codec in order to be usable.

Please review the supported codecs list PDF found here:

If you are using a format that appears to be supported but doesn't, then it is Studio only. This post also belongs in the DaVinci Resolve Beta forums, not in the Software Developers forum.
