  • Summary changed from ffmpeg cannot recognize an wave file to ffmpeg cannot recognize an wave file PCM detected as mp1

comment:2 Changed 3 months ago by lesterkong

if I modify libavformat/wavdec.c line 157 st->probe_packets = FFMIN(st->probe_packets, 32); to st->probe_packets = FFMIN(st->probe_packets, 14); it's ok
