Can you post the command lines for demuxing/remuxing? Thanks
for demuxing, you can simply use tsMuxer.
then mp4muxer:
Code: Select all
mp4muxer_64bits.exe --dv-profile 5 --input-file video.hevc --input-file audio.ec3 --output-file new.mp4
Thanks, but this ins't working here: I only got an empty file, it reads the 2 extracted tracks for 5 minutes for ~100 MB/s but it doesn't write out anything, no error message, no nothing.
(I tried out 4 times, tracks extracted by tsmuxer and dbl mp4demuxer.exe as well, used mp4muxer_64bits.exe from
yusesope's post)
Don't we need other params for it?
Edit: worked finally for the 5th time (I used the mpeg4-comp-brand flag as well, dunno whether this helped or not), but the whole process lasted more than 30 minutes for whatever reason (it read the 2 demuxed files for 5 minutes, then did something for 20 (?) minutes without any disk activity, then it wrote out the whole file in once for another 5 mins). So, thank you for the help.
Here are the steps using dlb tools:
Demux:
Code: Select all
mp4demuxer.exe --input-file foo.mp4 --output-folder tmp
Remux:
Code: Select all
mp4muxer_64bits.exe --dv-profile 5 --input-file out_1.h265 --input-file out_2.ac3 --mpeg4-comp-brand mp42,iso6,isom,msdh,dby1 --output-file try.mp4
