Hello,

I have an issue with remuxing BL + EL video streams into a single Dolby Vision stream, I have tried with both the Windows and Linux binaries, they read the whole source files but never writes into the output file, and the command never exits I have to kill it. Tried with different profiles also.

Command: ./mp4muxer_64bits.exe --overwrite --dv-profile 4 --input-file 00014.track_4113.hevc --input-file 00014.track_4117.hevc --output-file F:\Ready.Player.One.2018.2160p.UHD.BluRay.HDR.HEVC.mp4

Output file: output.zip

Could you have a try with some short clips? Usually the tool need take several minutes to handle the huge files, how long do you wait for?

Poilaucul commented 5 years ago

It worked, just took 42 minutes.

I would say approximately 35 minutes to get some output to the output file. Takes time because it's single threaded I guess.

ShaoWeiguo commented 5 years ago

Yes, it's single thread. The front-end provided is just a simple example. The purpose of this project is to help Dolby's partner or 3rd-party muxer/packager to support Dolby's codecs.
