On this page I will try and pull together a number of recipies for encoding video into different formats.<\/p>\n
This method requires three steps. Now assume we have a file called This will extract the video, scale it and reduce the frame rate. Now we need to extract the sound.<\/p>\n An output file called I have been told that this can be done in one command as follows<\/p>\n For this to work, faac and xvid need to be configured in ffmpeg. For 16:9 video, use:<\/p>\n This one comes from the Hampshire Linux User Group mailing list. This is used to rotate a video by 90 degrees.<\/p>\n That will create a bunch of VOB’s in a sudirectory called DVD. However, I am currently having a few problems with this on damaged mpeg files where the audio goes out of sync with the video. I am currently playing with ffmpeg to see if I can come up with a set of options to replace this command, and fix the audio. The following has worked best so far.<\/p>\n That will do some stuff to create the title<\/p>\n Actually create the title VOB and prepare the xml file for dvdauthor.<\/p>\n That will bunch the whole lot up ready to burn to a disk.<\/p>\n Burn baby, burn!<\/p>\n This process still needs some tweaking as the menus are not working properly yet. I expected that I would have a still picture for each button, but all I have is blank squares with a play button above. <\/p>\n The above are recipies that I have actually used, and recorded here for future reference. Here is a link to some more that may be usefull, but I have not actually tried myself.<\/p>\n http:\/\/streaming411.com\/wiki\/index.php?title=Encoding_prerecorded_video<\/a><\/p>\n I have decided to have a go at archiving some of my MythTV recordings. This has proven to be a little more problematical than first expected, as the OOTB solutions just did not quite do the job.<\/p>\n First use the edit function in MythTV and set up the cut points to remove adverts etc., then log into Mysql, and select the This will list all the recorded programs, and the other information that is needed for the next step. Now run Note that the start time required by mythtranscode is in a slightly different format to that stored in the Mysql database.<\/p>\n Once I have done this, I then use the recipe mentioned further up the page to record this file as a DVD.<\/p>\n Another way<\/a> On this page I will try and pull together a number of recipies for encoding video into different formats. 3GP for Mobile Phones This method requires three steps.
