One reason could be that your input mpg file

You can use ffmpeg debugging to learn more about your video stream.
ffmpeg -i C:\1adapt.264 -
OMG, when i check the I-Frames by JM software, that software shows only 3
I-Frames. how this is possible? please help me to understand where is my
problem?

I am confusing guys, i encountered a new problem in regard with adaptive
and fixed rate I-Frames by ffmpeg under windows. it is as below:
first i convert the original video (mpeg1) to the pure h.264 format by
below command for adaptive I-Frame rate:
ffmpeg -i C:\1.mpg -r 25 -an -vcodec libx264 -th
I usually use SMPlayer, but even ffplay shows the same behavior (the speed
is twice so the time length is half).
my version of VLC can not play .264 files, may be i need to install a patch
or upgrade it.

Just cast the buffer.
uint16_t* planes[3] = {(uint16_t*)
Hi,
I would like to decode 10bit videos into PIX_FMT_YUV422P10LE pixel format,
using:
struct SwsContext* swContext = sws_getContext(width, height,
originalpixfmt,
width, height, PIX_FMT_YUV422P10LE,
SWS_FAST_BILI

Knowing that what is tbr exactly, can not solve the problem. the frame
rate are same technically, when you compare the information by ffmpeg. The
fact is that the transformed video, after using vcodec libx264, is twice
faster as the original video. when i compare the information of bot video i

Then your answer was clearly more helpful than mine!

But tbr is not the framerate.

Hi
I convert a mpeg1 video mpeg4/ AVC by the below command but i dont know why
the visual frame rate become double after conversion (fps in both are same
but tbr will be twice as the original video)
ffmpeg -i C:\Video\TrecVid-Video\2\1.mpg -r 25 -an -vcodec libx264 -threads
0 -f h264 -r 25 -g 0 C
