I try to transcode UDP stream to HLS (m3u8) file and put that file in a web server such as apache with this code:
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
At first of trascoding progress i see a error
[h264 @ 0x14c1c60] number of reference frames (0+4) exceeds max (3; probably corrupt input), discarding one
But m3u8 file created successfully and i can play it in client. but after 2 or 3 minute i see some error
[h264 @ 0x158d600] error while decoding MB 30 34, bytestream -10 dup=101 drop=0 [mpegts @ 0x149c660] PES packet size mismatch

udp://239.1.2.1:60001: Input/output error
And stream stop immediately .... anybody know how i can solve this problem?
Try increasing the buffer size in the URL itself. For example:
ffmpeg -i udp://239.1.2.1:60001?fifo_size=50000000
