recording with ffmpeg not working [Solved]

[savage007]

Hi, this script is not working, i get zero results, but when i put the command ls instead of ffmpeg.... i get the directory listing in domoticz log.

The ffmpeg command works at the commandline. I had to put in an escape \\ for the ! In my password.

I also tried another command, “rm ~/abc.avi” , this also didnt work.


Does anybody now how i can fix this?

This is the log with command "ls"

Can you try this ? Explanation in script comments.
[EDIT] removed left behind echo command

Code: Select all

return {
    on = {
        devices = {
            'Alarm signaal'
        }
    },
    execute = function(dz, item )
        
        local scriptLog  = (_G.scriptsFolderPath):gsub('/scripts/dzVents/scripts','') .. '/scripts/dzVents/data/' .. 'ffmpeg.log' 
        
        local function popen(cmd)
            local f = assert(io.popen(cmd, 'r'))
            local s = assert(f:read('*a'))
            f:close()
            return s
        end
        
        -- original => potential problems:  other user, will block eventsystem for 10 seconds, \\ not escaped  
        -- cmd="ffmpeg -i rtsp://user:abc000\\[email protected]:88/videoMain -t 10 -acodec copy -vcodec copy abc.avi"  
           
        -- modified => use sudo to execute command, add a & to execute in background, escape \\ 
        ffmpeg_cmd=[[ sudo ffmpeg -i rtsp://user:abc000\\\\[email protected]:88/videoMain -t 10 -acodec copy -vcodec copy abc.avi & ]] 
        
        -- extra command to show in ffmpeg.log what the command will look like 
        echo_cmd=[[ sudo echo ffmpeg -i rtsp://user:abc000\\\\[email protected]:88/videoMain -t 10 -acodec copy -vcodec copy abc.avi > ]] .. scriptLog .. '&'

        dz.log('return from echo command: ' .. popen(echo_cmd) .. '\tCheck content of ' .. scriptLog, dz.LOG_FORCE)

As you can see the output is empty( i highlighted the time stamp ).

The escaping is alright now, i have checked this.

Can you please try again ? I removed a left behind echo command in my previous post.

Kind of hard to trouble shoot as I don't use ffmpeq myself and it does not seem to produce any error log, so it is a kind of point ans shoot..

Does the same command work if you try it as the same user that is the owner of the domoticz process ?
Did you try with and without sudo ?
can you put the command in an executable bash file and try to execute that from domoticz ?

[savage007]

I have tried it with a bash file it works!

Thank you for your time !!
