Just for learning purposes, may i know why is the mp4 video playable (when setting sink to be file sink) only after sending the eos signal event? is it ok to explain what is the use of this end of stream signal?

Hi,
Please check structure of mp4 file:
MP4 File Format

While recording, it puts bitstream into mdat atom. After receiving end of stream, it completes mdat and puts moov atom. Without moov the file is not playable.

For packet-based file formats such as ts or mkv, it can keep most stream without end of stream. Plesase refer to structure of mkv file:
MKV File Format
