Thanks for your response.
Calling GetFrame function will decode the entire video frame.
Instead we need only some information like frame type, resolution etc by parsing the header.
We need your inputs on how to identify the frame type and resolution, without decoding the entire frame. A code snippet will be very helpful for us to proceed.
our mpeg4 decoder expert suggest you checking the following code on read the resolution and frame type information:
In the file, mp4parse.c:
mp4_Parse_VideoObject() and mp4_Parse_VideoObjectPlane() functions (mp4parse.c) read the information in question from the stream.
