Stream cannot be transcoded but can be played with ffmpeg

Hi, all. I've encountered a stream that cannot be transcoded by ffmpeg with cmd:
Code: [Select]
ffmpeg -i "http://stream.ksntv.com.cn/live/pc2?fmt=H264_450K_FLV" -acodec pcm_s16le -f wav any.wav

but i can play it with ffplay:
Code: [Select]
ffplay "http://stream.ksntv.com.cn/live/pc2?fmt=H264_450K_FLV"


Please help and thanks in advance!

I'd use mplayer like;
Code: [Select]
mplayer "http://stream.ksntv.com.cn/live/pc2?fmt=H264_450K_FLV" -cache 10000 -vo null -vc dummy -ao pcm:fast:file=filename.wav
PANIC: CPU 1: Cache Error (unrecoverable - dcache data) Eframe = 0x90000000208cf3b8
NOTICE - cpu 0 didn't dump TLB, may be hung

If you want to avoid the command line and use a Windows front-end, try SUPER (FREE).  It uses FFMPEG and MEncoder.  It can transcode between many formats and/or extract/convert audio, etc.


(If you download SUPER, beware of adds for other conversion software on their website...  Follow the confusing links and make sure you are downloading SUPERsetup.exe.)
