I need to extract some informations abour a ts file containing h264 video.
I want to know where the I frames are.
I can't find somethong on the net which explain the ts h264 structure. So if someone have a link ...
I have already done it with a stream containing a mpeg2 video (I found this page : http://dvd.sourceforge.net/dvdinfo/mpeghdrs.html)
Thank you for your help.

A question really for superuser.com.
If you want just location of I pictures and some other details use ffprobe [comes with ffmpeg]
ffprobe -show_frames inputfile
will give details of picture type, size etc.

I have a 3.5mm to IR sensor to connect to my headphone jack. I want to know if there's a way to create a basic app for my TV that will control it's Volume, Power On/Off, input, and number pad. I've kept researching for about a week now on how to do this, but haven't found an answer. Can someone help me?
Yes is it possible, you only need an application what play wav files.
Or jsut a file browser.
But you can find a plenty of applications and tutorials and details all over the internet.

I am downloading an MP4 from a server by writing the file data directly to the app's documents folder. My question is - is there a way to start playing this file before it is fully downloaded?
According to https://trac.mplayerhq.hu/ticket/748 this is not possible because important information is missing from the file. I haven't studied the container format myself to confirm that.

I saw that this company Mitek made an app that could read receipts through the iPhone's camera and record the information from them. (http://www.miteksystems.com/OOMPH_MobileReceipt.asp). My assumption would be that they run the images through some kind of image/text recognition software. Any ideas what what they might be using? If theres an API that can interpret text from pictures that would be great to.
cheers,
Mike
They are probably using some type of OCR software. It is hard to tell exactly which.
You can look at ocropus, for example

Just by messing around a little it seems that the video stream is not ascii. i tested by downloading the stream. It would be insane if it was. Theres so many videos. So that couldnt be it. Youtube seems to not work with javascript disable (not counting mobile if true).
How is it being done? is it javascript magic? is the SWF running the video through a filter in realtime? (I doubt its a native filter so how is the filter compiled) its really cool. I cant imagine how this is running realtime yet it is!
MPlayer uses AALib for this type of effect. YouTube have probably ported it to ActionScript.
