Hi there,
I need this answered urgently,
so I do apologize if I have used an inapporiate tone.
I'm using a linux os (openSUSE 10.2) and the following:
libavutil version: 49.6.0
libavcodec version: 51.49.0
libavformat version: 52.2.0
I want to encode yuv into intraframe H264, but I have no idea how to go about
doing it: setting the parameters, using the correct codec, etc.
I can convert the yuv to other formats such as mjpeg
( ffmpeg -s 352x288 -i input.yuv -vcodec mjpeg output.avi ).
But I can't seem to make ffmpeg use the H264 codec. I saw the following
under 'ffmpeg -formats':
file formats:
DE h264 raw H264 video format
codecs
D V DT h264
I tried 'ffmpeg -s 352x288 -i input.yuv output.h264'
and 'ffmpeg -s 352x288 -i input.yuv -vcodec h264 output.h264'
but both do not work.
>From googling online, some sites mentioned that x264 was needed. If it is
>needed,
how do I install it into my existing ffmpeg?
On a related note, it would be greatly appreciated if someone can provide C++
code
on how to do the following:
-- read in a yuv file frame by frame
-- encode each frame into infraframe H264
-- write encoded frames into an output file.
Regards,
Lim Guorong
