Thanks for this. Had to add ‘no8x8dct’ to the x264encopt in order to make the H.264 stream baseline compatible. Also, it doesn’t hurt to add ‘level_idc=30′ to force the H.264 level to 3.0. I think the latest builds of x264 figure out the required level and profile, which is why video stream was initially High profile (8×8 DCT on by default=High profile).

Yes, im aware of that, interestingly enough, it looks like something changed when it comes to video playing in the latest iPhone/Ipod’s… im investigating whats the issue.

Hi, I tried your apple ad page for iPhone (with latest fw) and the iPhone can’t play your videos.
I tried with an iTouch as weel (older fw) and it can only play the sound.
I’m searching a solution to use encoded video in my website like you

I have discovered that I can encode 720X480 24 fps video for the iphone 3G and it works great. I’m using MPEG Streamclip. I then use YAMB to set the widescreen flag and mux the video and audio. You must use a custom 32/27 aspect ratio setting to get perfect 853X480 output. I tried this because I noticed that “digital copy” movies are encoded at 720X480 and play perfectly in the iphone 3G.

Hi Diego,

After some more encoding I’ve come across another issue which I’ve not yet found the fix…

It seems when encoding some videos I’m getting dropped frames, I tried to fix this by adding -vf harddup but it still happens. As mencoder processes the video with no audio it unfortunately results in sync issues.

Do you (or anyone else) have any ideas which may solve this?

Many thanks,

Tristan.

Found the issue…

In the above scripts you’re missing “level_idc=30″ in the mencoder passes for the iPhone/iPod, this seems to resolve the issue of “This movie format is not supported” for me.

Hope this helps others, loving the scripts!!

Hey Diego,

Just tried “iPhone Teaser: Hello” and that worked perfectly, strangely the m4v I made using the script still shows the “This movie format is not supported” error which is a shame but at least its my problem, not the scripts.

Thanks for some great tips!

Tris.

Hey Tristan, thanks for the comments. Regarding your problem with the videos on this site, i had not the time to re-encode all of them yet, only the “iPhone” and “Get a Mac” sections are “iPhone/iPod Compatible”, try any of those sections and report back if you have the time.
Thanks.

Hey Diego,

Fantastic script, I’ve just been using the x264 one which is brilliant!

I’ve got an iPhone 3g with 2.1 firmware and thought this would be a great way to convert files to play on my iPhone.

However I tried some clips from your apple video archive and when trying to play I get”This movie format is not supported” on my iPhone.

Its not jailbroken so I find it strange I get that error

Eudo:

Your ffh264 and ffodivx both play fine on my iPhone (for reference) which is extremely interesting.

Tristan.
