I have now completely de-installed and removed the ISPY package (also
known as ‘AgentDVR’), according to the process explained on their site.
Next, I have checked the install log file that had been generated by
this previous install process :
/var/log/agentdvr_setup.log (1156 lines)
which shows that this ‘ispy’ or ‘agentDVR’ install...
HAD TRIGGERED AN UNEXPECTED UPDATE of my system… ! (automatic updates
were de-activated in my Debian 11)
Now, googling the web, I found several posts from other debian 11 users
who complained that their VLC ceased to play mp4 and other H264 files,
right after an update of their system !
One of these complainers got a reply, advising to install/re-install
libavcodec58… which seems to have solved his problem. I tested the same
thing here, to no avail. There may be some other codecs that I should
install/re-install… but I don’t know which ones…
Thanks in advance for your help solving my VLC / H264 problem after that
unexpected update of my Debian 11

Hi to Everyone !
vlc 3.0.21 (Vetinari) – Debian 11
⇒ vlc no longer reckognises nor plays mp4 files ; it now only plays
their audio part :
« Codec non pris en charge:VLC ne peut pas décoder le format « h264 »
(H264 - MPEG-4 AVC (part 10)) »
needless to say that it did work before !
