Comment (by polochon):
Thank you for your answer. What is the argument you are using with
mediainfo command? I didn't know this tool and the option --full don't
show the same output.
Several points:
- I see there is a "alignement byte"
Alignement: (1 bytes)
02D ...Continued - Unknown - 1 (0x1) (1875 bytes)
but I don't find it with hexdump. I'm surprised, the sequence I have is 53
07 00 00 7f 7f 7f 7f... but maybe it is normal, I confess I don't read
completely the RIFF specifications. Just in case: do you know exactly
where I can find the part of the spec describing the size and the
alignment?
But if you assume there is no issue, so maybe the real issue is on the
"player side" which is the robot's firmware.
I also add the -bitexact option to remove extra infos that I have without:
please see ffprobe output:
Metadata:
encoder : Lavf58.29.100
this cause another issue with the robot, so I added -bitexact. If you have
a better option please let me know!
thanks A LOT
Pol
