If you save the video file into “.m4v” format and the file is closed, you can use

this function to decode the video file and retrieve the video image with a

callback function. The video images can then be displayed in the Windows

environment.

AngeloMPEG4_Decode_Get_FlowRate(channel, Byte_Second):

If the connection between encoder and decoder is established, use this

function to query the current data flow rate between encoder and decoder.

AngeloMPEG4_Decode_ReInitialEx(channel, Bitrate, frame_rate,

Angelo_Video_Format)

Because the bit rate and frame rate are initialized at the encode site, the

decoder uses this function to reset the image quality, if there is a connection

established.

Note: if one decoder changes the image quality, all the other decoders will

also receive the new image quality.

AngeloMPEG4_Decode_ReInitial(channel, Quality , Angelo_Video_Format):

Because the Quality is initialized at the encode site, the decoder uses this

function to reset the image quality, if there is a connection established.

Note: if one decoder changes the image quality, all the other decoders will

also receive the new image quality.

AngeloMPEG4_Decode_Get_Config:

User must define a callback function, than call

“AngeloMPEG4_Decode_Set_Callback”. Use “AngeloMPEG4_Decode_

Connect” to establish the connection, if the connection is made, the callback

function will receive a notification event. Then you can use

“AngeloMPEG4_Decode_Get_Config” to get the image configuration (e.g.

width, height, Bitrate, and frame_rate) from the encode site.
