我現在用Linux上面的ffmpeg轉檔
想把網路上抓到的avi轉成flv
指令為
ffmpeg -i source.avi -vcodec flv output442.flv
可是它給我的錯誤

[NULL @ 0xa58c540]Invalid and inefficient vfw-avi packed B frames detected
Seems stream 0 codec frame rate differs from container frame rate: 24.01
(65535/2730) -> 24.00 (24/1)
Input #0, avi, from 'source.avi':
Duration: 00:02:32.70, start: 0.000000, bitrate: 1133 kb/s
Stream #0.0: Video: mpeg4, yuv420p, 640x360 [PAR 1:1 DAR 16:9], 24 tbr, 24

Output #0, flv, to 'output442.flv':

Stream mapping:
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
[adpcm_swf @ 0xa5a48c0]Sample rate must be 11025, 22050 or 44100
Error while opening codec for output stream #0.1 - maybe incorrect parameters
such as bit_rate, rate, width or height
我看官網的說明，並沒有關於640 x 360這個解析度的說明
請問我的參數要怎麼改，才能順利轉檔
謝謝
