Haha that's exactly what I'm thinking, I downloaded the handbrake source last night, I wanted to poke around it today, but quite simply learning C , the different types of open source video decoders, the muxers, and then the intricacies of the program itself mean by the time I'm done, they'll have it done much quicker.
Got a tip for us?

Of course there is, it is used by Handbrake...I know it *can* be done, but there is no mp4 muxer right now that will do it properly, so in practice it can't be.
And it would take a major rewrite of how Handbrake is structured. Quite simply, it was made with MPEG2 sources in mind.Haha that's exactly what I'm thinking, I downloaded the handbrake source last night, I wanted to poke around it today, but quite simply learning C , the different types of open source video decoders, the muxers, and then the intricacies of the program itself mean by the time I'm done, they'll have it done much quicker.

Getting AAC into an MP4 container isn't a problem though, is it? Everyone wants AC3 because no cheap receivers can decode 5.1 AAC, also my understanding was converting AC3 to 5.1 AAC messed up the channel order.Bingo.
Managed to get AutoMKV (google it) to give me a nice .aac track that I can throw into yamb and then remux with my h.264 to give me an .mp4. REMEMBER, you need to manually set the fps in yamb to 23.967.
But, I'm still not quite there yet. I need to the "Level" to 3.1 to have Apple TV play it back. It's getting late though...More tomorrow.

The two problems with MKVs I know right now are that you can't mux 5.1 AC3 right now and 99% of the time the video track is using some h.264 encoding feature that is unsupported by Apple's H.264 implementation/Apple TV horsepower.
I could be mistaken, but I believe he (dynaflash) is referring to this post:See the above post.
I wish VisualHub would make .m4v and I wish Handbrake would accept more input types. If I knew how to program I would be working hard on it.... maybe I need to learn!
No, MP4 and AAC go together very nicely. As far as I know, there are no home receivers on the market that can currently decode 5.1 AAC (I recall hearing about one a couple months ago, but don't know if/when it will make it to market and it definitely wasn't cheap). I don't know about the channel order issue as I never encoded to 5.1 AAC.Getting AAC into an MP4 container isn't a problem though, is it?
