Do the ffmpeg libraries expose hardware encoding capabilities? (I'm
mainly looking for NVENC). I've been looking at the ffmpeg source code
for a bit now, but I cannot find where it is implemented, although I
could encode directly with the executable (I compiled), hope I get
some kind of response this time, I'm sorry if my mails are too
newbie/dumb for this mail list but I want to learn to use the ffmpeg
api libraries and I'm going at a snail's pace :).

Yes, you need to have the NVidia Video SDK when you build.
./configure --prefix=/usr --bindir=/usr/bin --datadir=/usr/share/ffmpeg
--incdir=/usr/include/ffmpeg --libdir=/usr/lib64 --mandir=/usr/share/man
--extra-cflags=-I../Video_Codec_SDK_7.0.1/Samples/common/inc [...]
--enable-nvenc [...] blah blah blah
The path --extra-cflags=-I is to the nvEncodeAPI.h file needed and
--enable-nvenc adds the h.264 encoder
See ./libavcodec/nvenc.c
Thanks

Charles thanks for your answer. I've already compiled using the Nvidia
SDK, the thing is that SDK example code is.. uhm.. so I was trying to
lol ... yes the Nvidia Sample code is uhm...
You can verify you ffmpeg is build with nvenc
linux2 8:28am avlib >> ffmpeg -encoders |& grep h264_nvenc
V..... h264_nvenc NVIDIA NVENC H.264 encoder (codec h264)
I am not following what you trying to do? Use ffmpeg or direct to nvidia
nvenc...
Thanks
cco
read FFmpeg's source code instead looking how were you using it.
Reading the nvenc.c code and correct me If I'm wrong but setting up an
AVCodecContext, calling ff_nvenc_encode_frame with a frame and receive
a packet to write would do it?
