mismatch level in decoder

Hello,

If any decoder (not TI’s) support only 3.1 and below level, and receives ES with resolution,fps, bitrate parameters below 3.1, but indication in ES of ‘4.2’ how will that decoder behave ? Will it decode the ES properly ?

Best Regards,

Ran

    Ran,

     

    There is no sure answer for this, since it depends on the implementation.

    Some decoder implementations, check the level and discard the stream if it is above the supported level.

    Some decoder implementations (Like TI), check the actual parameters like resolution etc and then decide if the stream can be decoded or not. This is a better implementation since many encoders blindly put in a higher level number, though the parameters belong to lower level.
