Hi all,
I am using FFMPEG library to mux H.264 and AAC frames to Matroska (.mkv)
file. I can do that both using command line and C program.
Now, instead of writing the muxed matroska data into file I want to
write these muxed data directly on to socket or pipe. My actual goal is
to write a C program that send muxed data to socket and server will
receive this muxed data.
I tried using protocol tcp. They are working with the matroska format.
So, My C program is able to send muxed data successfully over socket and
server is able to receive this muxed data.
But when I apply ffprobe command over the received file, I am getting
duration and bitrate field N/A. and when I tried to play this file with
vlc i am unable to seek the file and getting garbage duration.
Below the output of the ffprobe.

As You can see Duration and Bitrate field shows N/A. However I am
getting correct startTime.
Any help or advice? Thank you in advance.
