#!/usr/bin/python##I have taken the concept of this script from http://s91928265.onlinehome.us/hfamily/mythtv/myth_ubuntu.html##The script has not been updated in awhile and since Ubuntu Feisty came out, it no longer works##I asked in #bash and everyone agreed that the original writer did not do a very good job. So I am going##to take over and convert it to python and hopefully keep it up to date and working. I hope to add some extra ##features to it##like an option to burn the dvd after creating the iso file!##James Middendorff a.k.a riddlebox##06/09/07####USAGE: python makedvd.py ProjectName filename.mpg/nuv##Depends on dvdauthor##############################################################################################################Notes to myself while writing this!## 1. Use sys.argv to pass arguments at the commandline!## 2. Use sys.argv to create a -h to show the description and how to properly use the script## 3. Create Functions to do the actual work!## 4. use os to run the commands instead of popen3## 5. add error detection features, and possibly a gui to go along with it## 6. have a gui or even commandline option to burn the dvd directly instead of creating the isoimport osimport sys#create the variables for python to create the project name and take the file name#will eventually have more than one filenameprojName = sys.argv[1]file1 = sys.argv[2]#file2 = sys.argv[3]#file3 = sys.argv[4]###These lines will setup our commands to actually do the work!def cleanUp(): os.remove('aud0') os.remove('vid0') os.remove('dvdmpg') os.system('rm -rf dvdproj') print 'finished cleaning up files' print 'Successfully completed the project, now you must burn the iso and enjoy!'def sub_mkiso(): print 'Starting the mkisofs process.....' sub_mkisofs = os.system('mkisofs -dvd-video -udf -V MythDVD -r dvdproj/ > MythDVD.iso') if sub_mkisofs == 0: print 'Success creating the iso file' cleanUp() else: print 'An error occured'def sub_dvdAuth2(): print 'Starting the second round of dvdauthor.....' sub_dvdauth2 = os.system('dvdauthor -o dvdproj -T') print 'Success with dvdauthor -o dvdproj -T' sub_mkiso()def sub_dvdAuth1(): print 'Starting the first round of dvdauthor' sub_dvdauthor = os.system('dvdauthor -o dvdproj -f dvdmpg') if sub_dvdauthor == 0: print 'Success with dvdauthor -o dvdproj -f titlename' sub_dvdAuth2() else: print 'An error occured'def sub_mplex(): print 'Starting the mplex' sub_mplexAll = os.system('mplex -f 8 -V -o dvdmpg aud0 vid0 &') if sub_mplexAll ==0: print 'Success with mplex -f 8 -V -o dvdmpg aud0 vid0' os.popen3('mkdir dvdproj') str = "dvdmpg" sub_dvdAuth1() else: print 'Returned an error'def sub_mv(): print 'Starting to mpeg2desc the video' sub_mpeg_video = os.system('mpeg2desc -v0 < %s > vid0 &'%file1) if sub_mpeg_video == 0: print 'Success with mpeg2desc -v0 <%s> vid0 '%file1 sub_mplex() else: print 'Returned an error'def sub_ma(): print 'Starting to mpeg2desc the audio' sub_mpeg_audio = os.system('mpeg2desc -a0 <%s> aud0 &'%file1) if sub_mpeg_audio == 0: print 'Success with mpeg2desc -a0 <%s> aud0'%file1 sub_mv() else: print 'Returned an error'##Here is the main app##First we will show the description and how to properly use the script, which I will hope to make this part a help file of some sortprint ""print "makedvd: From a set of MythTV recordings, create an ISO"print " file suitable for burning directly to"print " a DVD.
