Hello
I am new in image processing. Sorry for stupid questions.
Currently, i am developing commercial application for recording video strea=
m from IP camera in real time.
Also i need to add information to some of the frames. It will be like image=
metadata. For example, time of capturing, location, comment,... And of cou=
rse i need to be able to read it later. As i understand, i need to use subt=
itles or it is another way exist? But in any way want to keep it inside of =
video file.
I already tried OpenCV. Not really happy with it because of codecs selectio=
n and no way to work with subtitles. You can find my questions here.
http://answers.opencv.org/question/100967/codecs-list/
http://answers.opencv.org/question/101044/add-subtitles-to-video/
Can you help me please to find a way to do it in matroska. Or it is a wrong=
tool for my task?
Thank you.
