When dumping packets, also dump the payload. @item -re (@emph{input}) Read input at native frame rate. Mainly used to simulate a grab device. +By default @command{ffmpeg} attempts to read the input(s) as fast as possible. +This option will slow down the reading of the input(s) to the native frame rate +of the input(s). It is useful for real-time output (e.g. live streaming). If +your input(s) is coming from some other live streaming source (through HTTP or +UDP for example) the server might already be in real-time, thus the option will +likely not be required. On the other hand, this is meaningful if your input(s) +is a file you are trying to push in real-time. @item -loop_input Loop over the input stream. Currently it works only for image streams. This option is used for automatic FFserver testing. |
