roStorageHotplug not working expectedly

Hi!

I am trying to create a BrightScript that recognises automatically when a USB memory stick is attached or deattached from the player and then plays videos from the root folder of the USB stick.

I am using roStorageHotplug for this. It is connected to roMessagePort and I am waiting for the messages. However, the messages are never sent because the unmounting fails as the system is reading a video from the USB stick. Is there any way around this?

I managed to get it trigger one time randomly. After that when reattaching a usb stick, the program could not find the new files as in the mounting phase the new usb was assigned to storage/usb2 as according to it storage/usb1 was already existing. This is another problem I need to solve somehow?

Any ideas of either of these points? Or am I thinking about this in a too complicated way?

Best, Miro

  Sounds like you could add a delay between the hot plug event and video playback.

  Something like sleep(1000)?

  If that doens't work then you might need to start a roTimer.

  Thanks for the reply.

  Here is my code where I tried different methods for triggering actions based on usb stick presence. Basically just extending the readymade autorun example that plays all the files from sd card.

  Do you mean I should add the delay in the roStorageAttached event?

  debug=true
  
  VideoResolution$="1920x1080x30p"
  
  
  
  
  v=CreateObject("roVideoPlayer")
  
  p=createobject("roMessagePort")
  
  log=CreateObject("roSystemLog")
  
  hotplug = CreateObject("roStorageHotplug")
  
  hotplug.SetPort(p)
  
  v.SetPort(p)
  
  v.SetVolume(50)
  
  'v.SetLoopMode("AlwaysLoop")
  
  
  
  
  mode = CreateObject("roVideoMode")
  
  mode.SetMode(VideoResolution$)
  
  
  
  
  count=0
  
  playcount=0
  
  countfound=0
  
  countMax=100
  
  usbPlugged=false
  
  DIM mylist[countMax]
  
  
  
  
  
  
  
  read:
  
  list=ListDir("USB1:/")
  
  
  
  
  for each file in list
  
  if ucase(right(file,3)) = "MOV" or ucase(right(file,3)) = "MP4" or ucase(right(file,3)) = "MPG" or ucase(right(file,3)) = "VOB" or ucase(right(file,2)) = "TS" then 
  
  mylist[countFound]= "USB1:/" + file
  
  log.SendLine(file)
  
  countFound=countFound+1
  
  endif
  
  next
  
  
  
  
  
  
  
  play:
  
  if countfound=0 then goto read
  
  if debug print mylist[count]
  
  ok=v.PlayFile(mylist[count])
  
  playcount=playcount+1
  
  
  
  
  'advancing count
  
  if count = countFound-1 then
  
  count=0
  
  else
  
  count = count+1
  
  endif
  
  
  
  
  
  
  
  
  
  
  if ok=0 then
  
  if debug then print "Playback failed"
  
  goto play
  
  endif
  
  
  
  
  loop:
  
  
  
  
  if hotplug.GetStorageStatus("SSD:").present then
  
  if not usbPlugged then
  
  usbPlugged = true
  
  log.SendLine("USB REMOVED MANUALLY")
  
  endif
  
  endif
  
  
  
  
  if not hotplug.GetStorageStatus("SSD:").present then
  
  if usbPlugged then
  
  usbPlugged = false
  
  log.SendLine("USB ADDED MANUALLY")
  
  endif
  
  endif
  
  
  
  
  msg=wait(0, p)
  
  
  
  
  if type(msg) = "roStorageDetached" then
  
  log.SendLine("USB DEVICE DEATTACHED")
  
  countfound = 0
  
  mylist.Clear()
  
  v.StopClear()
  
  endif
  
  
  
  
  if type(msg) = "roStorageAttached"
  
  log.SendLine("ATTACHED USB")
  
  endif
  
  
  
  
  if type(msg) = "roVideoEvent" then
  
  log.SendLine("VIDEO FINISHED PLAYBACK")
  
  if msg.GetInt() = 8 then
  
  goto play
  
  endif
  
  endif
  
  
  
  
  goto loop
