Same here… I tried every possible codec on earth for mp4 but no video whatsoever is showing up, I can only hear audio. (flv videos play like a charm)

Hello Alberto,
if you are a Mac user, you can try following guide:
http://foliovision.com/2010/12/07/convert-videos-for-ipad-on-macOtherwise I would suggest to you the h264 codec, and maybe alter the properties, be sure to not use some strange video resolution, also alter/remove streaming options, and try other features your video encoding application supports.
For us, the above link on how to encode always worked on mac, which is if you have quicktime pro the easiest solution. On Windows it’s more complicated as you have probably installed some custom application for video encoding so we can really help here. We’ve been successfully using also the online service http://www.encoding.com/, but this is not entirely free.

Anonymous 13 years agoThank you Zdenka, I did manage to view mp4 movies correctly (it was a codec related issue) although I dind’t quite understand if FV flowplayer can handle streaming with mp4 or users will have to fully load the clip before viewing anything (I’ll run a test with a bigger movie). That would definately be a problem because I’m building a site where HD mp4 movies sit in a special performing host with extremely wide bandwidth in order to provide simultaneus view to a lot of users. I know someone has added a sort of script to achieve that, but do not recall where I read about it.
Best regards
Alberto
Anonymous 13 years agoThanx Zdenka, one more thing (this is really a minor issue). For some reason I do not know, when assigning a splash img to a movie I end up with a stripe of missing pixels on the right side just like if the picture wasn’t wide enough (but it is). In fact as the video finishes playing and the splash img comes back, it is displayed with the correct width.

thx AlbertoAnonymous 13 years agoYes I noticed it.. (found with firebug) but that is a default string in twentyeleven theme… not my editing. I tried to overwrite it with a img.splash {max-width:100%important!;} but it doesn’t work (I don’t want to touch the style of content in other pages). No problem…also this is a different thread and I rather not overdub a different subject.
thx anyway
Alberto
