[Mp4-tech] About the error resilience

[Sam Lerouge]

Hello Jefferson,
The MPEG-4 Visual standard offers a number of tools for error resilience.
Some of them, in particular resynchronization markers, can be useful in
packet-based transmission. These markers can help limiting the damage caused
by loss of data to only a part of the frame. Any decoder that complies to
the Simple Profile or Advanced Simple Profile should be able to deal with
resynchronization markers. However, not all encoders are capable of
inserting them in the encoded stream (it is not mandatory for an MPEG-4
compliant encoder), so you will have to find an appropriate encoder.
Still, a loss rate of 4% might be just too much for transmitting an MPEG-4
video in a visually acceptable way. Therefore, you might want to consider
other solutions, as mentioned by Vinay in another mail.
