transcoding(one input + two output)

Jump to solution

Hi Bjoern,

   Currently i am making the following transcoding scenario below: (one input , two output with different resolution)

                                                                                                    |-> VPP resize to D1 -> D1 encode -> RTP(or FILE)

     RTP(or File)  -> 720P decode -> YUV420 Frame (Video Memory) |

                                                                                                    |-> VPP resize to CIF -> CIF encode -> RTP(or FILE)

    as for upper block ,i have two issues to make sure:

   1.  one decode raw frame can be used by two VPP processor simultaneously , does it work? or any special usage to pay attention by application? 

   2.  i prepare to use three threads to handle upper scenario (except rtp handle), one for 720P decode, the other two for VPP resize and encode. is there any better or simple method to achieve this transcoding session?  any comments are well appreciated! 

Thanks,

Denny

Hi Denny,

Transcoding (one input +two outputs) can be achieved using the sample_multi_transcode in the sample package here (http://software.intel.com/en-us/intel-media-server-studio-support). Using a par file, sample_multi_transcode allows multiple concurrent (or joined) sessions (decoding, vpp, encoding) be executed at the same time. To learn more about sample_multi_transcode, please refer to readme-multi-transcode document included in the sample package. Thank you!

Thank you very much!!!

     rtp handle module (jitterbuffer) will integrated into my project ,do you have any suggestions for rtp integration , this issue perhaps is out of scope of media sdk , much appreciated if you have related experience for reference!
