[x264-devel] few quick questions

[Tom Jacobs]

a few quick questions so u can get a can get a good base to understand the
encoder.

 what actually is nal.  i have seen it on xvid to and never worked it out. i
think it is where the actual compressed data is stored but not sure exactly.

i am thinking that x264_encoder_encode is the main encoding function. the
whole frame and all its slices (am using Champ Yen parallel version,   very
much appreciated btw) are encoded from this point. but i am not sure exactly
how it works from there on. i am guessing somewhere it will have to be
broken down to a MB level.

if i have got this right in my head, for each MB the different number of sub
MB sizes are tested to see which gives the best approximation to the
original image. once all the test are done it is then compressed using that
size block.

from the parallel version of the encoder the main different i see is within
the slice_init start and write. is this where the programme flow goes
deeper into the encoding process?


for sayin i only had a few questions it has turned into a long post.  any
help would be much appreciated

Tom
