Hi,

I have a lot of problems configuring Web Access. I have set maximum size video size to 4K and bitrate to 80Mbps, and default Web Access profile, and most files are transcoding, even if they should be supported by the browser (MP4 with H264 and AAC for instance). Some files with these specs are playing without transcoding, some not. Also, I have MKV files with H264 and AAC, and they are still fully transcoded, why Mezzmo doesn't change container only, why it has to transcode them? I have attached the logs from attempts to play one file that works fine and one that transcodes with seamingly the same format.

Is there an updated Web Access profile that works better with new Chrome browser?

The container for mp4 has the max level set to 42, so if you have mp4 files with level 50 or higher they will be transcoded. The file being transcoded in the logs may be due to this, can you please post the ffmpeg information of the file by right-clicking on the file in Mezzmo and selecting 'Get FFmpeg Information...' then copy and paste it here.

Yes, it was level 50. But, what is the best way to avoid transcoding? Is there a plugin to install for the browser to handle MKV or MP4 that is a higher level file? Most of the files I have are not with proper level or they are H264/AAV in MKV container, and for HD for some files transcoding works under 25 FPS (I have Ryzen 3 with Vega 8 CPU, but FFMPG you use only have nVidia based encoding enhancements).

We can update the device profile so that level 50 files are passed to the browser without transcoding, send an email to support [at] conceiva [dot] com and we will send you the updated profile. You can also update the profile yourself, open the WebAccess.prf profile in a text editor (see this thread for its location: http://forum.conceiva.com/showthread.php/467-FAQ-Where-are-device-profiles-located) and look for level="42" and replace this with level="51" then save the file and restart your Mezzmo media server.
