ifile_get_packet()

int ifile_get_packet	(	InputFile *	f,

	)

Get next input packet from the demuxer.

Parameters

pkt	the packet is written here when this function returns 0

Returns

• 0 when a packet has been read successfully
• 1 when stream end was reached, but the stream is looped; caller should flush decoders and read from this demuxer again
• a negative error code on failure
