How can I add / mux cover art (JPEG, PNG..) to an OGM file. I have a series of these files which contain audio and video streams, and I would like to attach thumbnail photos. I have tried: 1) Appending an ID-3 tag. 2) mkvtoolnix to append the photo - but this alters the file format from OGG to Matroska. 3) Using the 'tagging' feature of foobar2000 - but foobar2000 states that the operation is not supported for the file type. 4) VirtualDubMod - I can open and save the OGM file but I cannot append an image. 5) VLC Player - I can edit metadata but I cannot commit the changes or even a picture. I have also Googled extensively. Help!
Sorry, not much to offer:if it was avi, I would use an AviSynth script to open in VirtualDub. 1 is the main video. 2 creates a small video of 75 frames @ 25fps = three seconds 3 merges the small video to a silent audio that has the same settings as the main audio 4 splices the small video to the front of the main video. Problem is that I haven't worked with OGM and I have nothing to test. Instead of 'AviSource' it might work with 'DirectShowSource' The VideoHelp site might offer more insight into ogm. Code: x=avisource("clip.avi").assumefps(25) y=ImageSource("splash.jpg",end=75,fps=25).ConvertToYV12() z=audiodub(y, blankclip(x)) z++x
