General Options

p will be created

P boundaries

 file

SWF Importer Options

SWF Importer Options

MP4Box can import simple Macromedia Flash files (".SWF")
You can specify a SWF input file with '-bt', 'xmt' and '-mp4' options

 -global              all SWF defines are placed in first scene replace
                       * Note: By default SWF defines are sent when needed
 -no-ctrl             uses a single stream for movie control and dictionary
                       * Note: this will disable ActionScript
 -no-text             removes all SWF text
 -no-font             removes all embedded SWF Fonts (terminal fonts used)
 -no-line             removes all lines from SWF shapes
 -no-grad             removes all gradients from swf shapes
 -quad                uses quadratic bezier curves instead of cubic ones

 -flatten ang         complementary angle below which 2 lines are merged
                       * Note: angle '0' means no flattening

ISMA Encryption/Decryption Options

ISMA Encryption/Decryption Options
 -crypt drm_file      crypts a specific track using ISMA AES CTR 128
 -decrypt [drm_file]  decrypts a specific track using ISMA AES CTR 128
                       * Note: drm_file can be omitted if keys are in file
 -set-kms kms_uri     changes KMS location for all tracks or a given one.
                       * to adress a track, use 'tkID=kms_uri'

DRM file syntax for GPAC ISMACryp:
                      File is XML and shall start with xml header
                      File root is an "ISMACryp" element
                      File is a list of "ISMACrypTrack" elements

ISMACrypTrack attributes are
 TrackID              ID of track to en/decrypt
 key                  AES-128 key formatted (hex string '0x'+32 chars)
 salt                 CTR IV salt key (64 bits) (hex string '0x'+16 chars)

Encryption only attributes:
 Scheme_URI           URI of scheme used
 KMS_URI              URI of key management system
                       * Note: 'self' writes key and salt in the file
 selectiveType        selective encryption type - understood values are:
   "None"             all samples encrypted (default)
   "RAP"              only encrypts random access units
   "Non-RAP"          only encrypts non-random access units
   "Rand"             random selection is performed
   "X"                Encrypts every first sample out of X (uint)
   "RandX"            Encrypts one random sample out of X (uint)

 ipmpType             IPMP Signaling Type: None, IPMP, IPMPX
 ipmpDescriptorID     IPMP_Descriptor ID to use if IPMP(X) is used
                       * If not set MP4Box will generate one for you

File Streamer Options

File Streamer Options

MP4Box can stream ISO files to RTP. The streamer currently doesn't support
data carrouselling and will therefore not handle BIFS and OD streams properly.

-rtp         enables streamer
-noloop      disables looping when streaming
-mpeg4       forces MPEG-4 ES Generic for all RTP streams
-dst=IP      IP destination (uni/multi-cast). Default: 127.0.0.1
-port=PORT   output port of the first stream. Default: 7000
-mtu=MTU     path MTU for RTP packets. Default is 1450 bytes
-ifce=IFCE   IP address of the physical interface to use. Default: NULL (ANY)
-ttl=TTL     time to live for multicast packets. Default: 1
-sdp=Name    file name of the generated SDP. Default: "session.sdp"
