MP4 file courruption power is cut down

[Waziri]

Hi, I want you to ask that if I use segmented mpeg2ts to record rtp stream
safely against power cut. If I use mp4mux when the power cut down, the last
file is not playable. Can you offer me any solution how can I fix that mp4
to a playable video, I am waiting for your help thank you...

You could play with the reserved-* properties on mp4mux to enable a
mode that regularly re-writes the mp4 headers. That way only the last
few seconds/minutes get lost, not the entire file.

Hi, sir thank you for your advice but I have these problems. Please can you
help me?

When I use Mp4mux, I set these properties;
reservered_moov_update_period or
moov_recovery_file  
It gives buffer has no pts error and record is stopped.
How can I fix that mp4 file. It shows 0 MB until the record is stopeed. If
the power is cut down while recording the mp4 file is not being able to
whatch. Thank you...

Hi, I use the option mux-overhead. This reserves space at the start of the file for the moov block. It then gets updated regularly so that if the system crashes or someone removes the usb-stick or similar, only the last few seconds are missing.
