I am transforming a DX50 file into h265 file

Here is the video info
Duration: 01:13:20.80, start: 0.000000, bitrate: 658 kb/s
Stream #0:0: Video: mpeg4 (DX50 / 0x30355844), yuv420p, 480x360 [SAR 1:1 DAR 4:3], 595 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn
Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 24000 Hz, stereo, fltp, 56 kb/s

when i transfer it into libx265 using
ffmpeg -i input.avi -c:v libx265 output.mp4
[Attachment 61489 - Click to enlarge]
the mp3float error never stops prompting
what's the error?

iirc this happens if ffmpeg is estimating the duration from bitrate (since the input lags proper headers, or has damaged headers) and durind the audio decoding often read too far ahead, this can but might not cause problems.

a. You could add 'loglevel fatal' to hide the output.
b. Does the input video play without errors when using ffplay?

I hope you are aware that this will cause additional quality loss. Also with your command line you are also reencoding the audio (to aac probably).

That's a good question.
The voice does break a lot.
What can i do for it?

That sounds like the audio stream is damaged.
If remuxing using mkvtoolnix and/or ffmpeg doesn't help and there is no repair software for it, you can't do anything about it,.. (aside from writing your own repair software or similar)
