When I used MediaConvert to convert my MP4 to M3U8, I found that the original 43-second video was only 40 seconds after conversion, and part of the AAC audio was cut off

"Original video information":

Invalid return value 0 for stream protocol Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'java.io.ByteArrayInputStream@27429ed8': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.37.101 Duration: 00:00:43.44, start: 0.000000, bitrate: N/A Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 960x576, 1261 kb/s, 10 fps, 10 tbr, 10240 tbn, 20 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 16000 Hz, mono, fltp, 70 kb/s (default) Metadata: handler_name : SoundHandler
