| 215 | | If you run into packet loss (since UDP is not guaranteed delivery, this might occur) first make sure your FFmpeg is compiled with pthreads support enabled (if it is, then it uses a separate thread to receive from the UDP port, which can cause less packet loss). You can tell that it is by specifying a url like udp://host:post?fifo_size=10000 (if it accepts fifo_size, then you're good to go). Similarly, for mplayer, you can use mplayer ffmpeg://udp://host:port?fifo_size=XXX for possibly better results on the receiving end. Alternatively, increase your buffer size, like mplayer ffmpeg://udp://host:port?buffer_size=10000000 (the default is 65K which is far too low for any reasonable transmission. |

Alternatively, increase your buffer size, like mplayer ffmpeg://udp://host:port?buffer_size=10000000 (the default is system dependent and typically far too low for any reasonable buffering. On linux though you can only set it to like 200K max anyway, so make sure this works: ffmpeg://udp://host:port?buffer_size=10000000?fifo_size=100000 (the fifo_size should not emit a warning, and implies that you have a secondary thread that collects incoming packets for you if there is no warning). |
