I'm making a H.264 Decoder on a board of NXP but I have some trouble in looking a OpenSource H.264 decoder and choose one to port to my board.
I see that FFMPEG project that includes H.264 Decoder.
Can I ask you a question that if I can use FFMPEG project as a reference for my H.264 Decoder on board NXP Trimedia ?
I've studied JM project, another H.264 Decoder OpenSource.But it seem very hard with me(its code).

Thank all.
Best regard,

PS. I'm sorry because my English is not good :)

I am also doing same project.
According to my view. JM is very much easy to understand compared to ffmpeg.

According to me, source code of JM project is more complicated than FFMPEG.
There are many files and many structures are declared in JM project and it takes me a lot of time to
undenstand :( .
Can you give me some experiences to understand JM more easily?
The problem that I am facing is how to choose a better and easily understand H.264 decoder between JM and
FFMPEG for a reference for my project.
And porting it to my board (NXP Trimedia). The most trouble in my project is how to optimize and port it (JM or FFMPEG) to my board.

Can you help me ?

Best regard,

While developing decoder JM is good to refer. Why because it follows stadard (h264). FFMPEG contains some extra features ans optimization also. So While optimizing u r code refer the ffmpeg. But to check u r code errors and quality better to compare with JM.
