Hi, Micael Silva.
I tried the command you sugested. The command was:
ffmpeg -analyzeduration 500M -probesize 500M -fflags +genpts -i
"concat:../vob/vts_01_0.vob|../vob/vts_01_1.vob|../vob/vts_01_2.vob|../vob/vts_0
Thank you very much for your help.

-vsync should be listed after the input, if you are looking for a constant
25fps try this:
ffmpeg -threads 1 -framerate 25 -i -vsync 1 -f

The input video is encoded with hevc at 25 fps.
I tries this command:
ffmpeg -threads 1 -vsync drop -i -f null /dev/null
I got this message in yellow:
Encoder did not produce proper pts, making some up
Unfortunately, I can not reach 25 fps while decoding, even with dropp

Maybe quotes within quotes
I am trying to run a batch conversion using ffmpeg and for files. It does work
except when i include the volume filter. Works fine with the quality filter on
it's own.
