I want to use h.264 encoder in bf531, source Code is from latest ffmpeg version,

because the 531 have no data ram in L1, maybe the  encoder efficiency in very limited?

any one who has do this jos same as me?

Can run 15 fps in cif(352*288) resolution in bf531 platform( sdram run at 133mhz, cpu run at 400mhz)?

Merry christmas!

thanks!

tks, but the url only refer to mpeg4 / avi encoder in blackfin not h264 encoder!

 

And in looked the source code in ffmpeg, the libx264 depend on the X264 lib, so i sould compile x264 and then move the

 

libx264 to ffmpeg, and comple, I thank the process is not suitable for blackfin, especially on bfin531.

 

any suggestion ?

We have not optimized x264 lib for blackfin Linux distribution. You are on your own.
