Streaming Video

Ok cool, I'll read through this stuff. Thanks for the info! Feel free to post whatever else you come across :P.

Those documents have a LOT of information that I don't really understand. The authors are writing down structs and commands that I have never seen or heard of. I simply need to get the video data, decode it if necessary, and display it in a widget. If this information is being shown to me and I am just too ignorant to find it, I apologize. If there are some more clear examples with more fleshed out code you (muisei) or anyone are aware of, they would be greatly appreciated. Thanks again!

Ok, so I found some code from the same project a few years ago. The person who wrote it is attemping to use UDP sockets to read in video data and then decode it with ffmpeg. I have been informed that the video I will be receiving and putting into my Qt program will be Mpeg4, but I don't know how it is supposed to be encapsulated. All of that is moot at this point anyway, because I am using VLC to stream video to the loopback address (127.0.0.1) and the Qt program is reading that in.

When I use the MPEG4 Codec with certain encapsulations, it will throw the following errors at me.

[mpeg4 @ 0x83ec350]looks like this file was encoded with (divx4/(old)xvid/opendivx) -> forcing low_delay flag

[mpeg4 @ 0x83ec350]warning: first frame is no keyframe

[mpeg4 @ 0x83ec350]ac-tex damaged at 18 3

[mpeg4 @ 0x83ec350]Error at MB: 141

[mpeg4 @ 0x83ec350]concealing 1116 DC, 1116 AC, 1116 MV errors.

I have attached the .cpp file where the decoding of the video is "supposed" to happen. Thanks for your help!
