I can trasfer the file recorded by recoder by following the parameter RDK fomulate like http://10.118.202.162:8081/vldms/dvr?rec_id=2017092917&segmentId=0
But I don't know how to transfer the file in same way,I see MediaUrl.cpp under rmfstreamer directory,this function bool MediaUrl::is_file_media() is not implemented yet
Can anyone answer it

    Hi Pierce Wang,

    From your query it seems you are looking to play any content from gateway (attached via a USB device) in a client device. Please elaborate more on this if this assumption is not correct.

    Thanks

      Your assumption is correct,I am looking to play content from gateway via USB device to any client device like VLC,Windows Media Player.In RMF_MediaStream.cpp::createSource this function,It define QAM ,TUNE,

      DVB,DVR_Locator,etc,but I can't see it defines File_locator inside it.

      Hi,get any update?

    File locators can't be directly streamed, however in test environments we can map a file to Source ID and stream using HN Source. Let's take following scenario in a Raspberry Pi Hybrid platform where a MPEG2 transport stream is streamed.

    • Keep a MPEG2 TS file in /opt/www/example_stream.ts (or in the USB mounted path).
    • Open /usr/bin/tune.config and edit following line to point to desired file. (we can map multiple files in similar manner)

          modulation:8 frequency:252 /opt/www/received_spts1.ts 2007

    • The above dummy frequency is mapped to a source id in /usr/bin/sidb.xml (4701 or Hex 0x125D)
      <program sourceid="4701" carrier_frequency="252" modulation_mode="8" program_number="-1" virtual_channel_number="3"></program>
    • Using above source ID we can stream the content and playback in another client such as VLC
    • For playing the streamed content in VLC use following URL:
      http://<IP_OF_RASPBERRYPI_GATEWAY>:8080/hnStreamStart?live=ocap://0x125d

    Note: We need to have a MPEG2 licence for playing the content in Raspberry Pi.

    How should we create similar codes basing on your instructions and our environment? and only ts format can be used as streaming??

    Open /usr/bin/tune.config and edit following line to point to desired file. (we can map multiple files in similar manner)

        modulation:8 frequency:252 /opt/www/received_spts1.ts 2007
