+Example: use @command{ffmpeg} to encode the input, and send the output |
|
890 |
+to three different destinations. The @code{dump_extra} bitstream |
|
891 |
+filter is used to add extradata information to all the output video |
|
892 |
+keyframes packets, as requested by the MPEG-TS format. The select |
|
893 |
+option is applied to @file{out.aac} in order to make it contain only |
|
894 |
+audio packets. |
|

+ffmpeg -i ... -map 0 -flags +global_header -c:v libx264 -c:a aac -strict experimental |

Note: some codecs may need different options depending on the output format; |
890 | 901 |
the auto-detection of this can not work with the tee muxer. The main example |

is the @option{global_header} flag. |
