ffmpeg的UDP來HLS錯誤

我嘗試轉碼UDP流HLS（M3U8）文件，並把在Web服務器的文件，如使用此代碼的Apache：ffmpeg的UDP來HLS錯誤

ffmpeg -i udp://239.1.2.1:60001 -acodec aac -strict -2 -vcodec libx264 -hls_wrap 100 -f hls /var/www/html/ts/1.m3u8

起初trascoding的進度我看到一個錯誤

[h264 @ 0x14c1c60] number of reference frames (0+4) exceeds max (3; probably corrupt input), discarding one

但m3u8文件創建成功，我可以在客戶端播放它。但2或3分鐘後，我看到一些錯誤

[h264 @ 0x158d600] error while decoding MB 30 34, bytestream -10 dup=101 drop=0 [mpegts @ 0x149c660] PES packet size mismatch 
[aac_latm @ 0x158daa0] Reserved SBR extensions is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. 
[aac_latm @ 0x158daa0] If you want to help, upload a sample of this file to ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing list. ([email protected]) 
[aac_latm @ 0x158daa0] Expected to read 18 SBR bytes actually read 21. 
[aac_latm @ 0x158daa0] channel element 3.4 is not allocated 
Error while decoding stream #0:1: Invalid data found when processing input 
Last message repeated 1 times 
[udp @ 0x148c0c0] Circular buffer overrun. To avoid, increase fifo_size URL option. To survive in such case, use overrun_nonfatal option 
[h264 @ 0x158d600] error while decoding MB 41 20, bytestream -14 dup=102 drop=0  
udp://239.1.2.1:60001: Input/output error

並立即停止流....任何人都知道我可以如何解決這個問題？

嘗試增加URL本身的緩衝區大小。例如：

的ffmpeg -i UDP：//239.1.2.1：60001 FIFO_SIZE = 5000

TNX很多......你知道如何解決這個問題？ [h264 @ 0x14c1c60]參考幀數（0 + 4）超過最大值（3;可能是損壞的輸入），丟棄一個 –

嘗試將幀速率設置爲固定值，看看是否可以解決它。 –

我看到sombosy使用'udp：//239.232.209.112：50000？fifo_size = 2000000'代碼爲-i選項，你知道爲什麼要使用fifo_size兩次嗎？ –
