failed in asr task

I try to test asr task in cli, but failed, do I miss anything?

$m4t_predict --model seamlessM4T_medium 16k.wav asr eng

@kaiser-ok from the error description, looks like the waveform you feed to the model exceeds the maximum sequence length once converted to log-mel filterbanks. Could you please try to run it with a shorter audio file and see if that fixes the problem?

@cbalioglu I got same error as well. It looks due to long audio file. Is it possible to support long audio in the future?

so, how long audio is supported? I tested with 1-minute 16kHz wav, tgt_lang "cmn", the result was very poor.
