使用gstreamer通過RTP流式傳輸mpeg2-ts視頻

Question

我想通過RTP使用gstreamer傳輸mpeg2-ts視頻。我使用下面的管道服務器：

gst-launch-0.10 -v filesrc location=/home/…/miracast_sample.mpeg ! rtpmp2tpay ! udpsink host=localhost port=5000 sync=false 

，我現在面臨的問題是，我得到直接EOS事件類似如下：

Setting pipeline to PAUSED ... 
Pipeline is PREROLLING ... 
/GstPipeline:pipeline0/GstRTPMP2TPay:rtpmp2tpay0: timestamp = 3878456990 
/GstPipeline:pipeline0/GstRTPMP2TPay:rtpmp2tpay0: seqnum = 50764 
Pipeline is PREROLLED ... 
Setting pipeline to PLAYING ... 
New clock: GstSystemClock 
Got EOS from element "pipeline0". 
Execution ended after 126835285 ns. 
Setting pipeline to PAUSED ... 
Setting pipeline to READY ... 
Setting pipeline to NULL ... 
Freeing pipeline ... 

我能理解，這是很運行快，但如何解決它？

Answer 1

您已將sync = FALSE設置爲「不同步時間戳，但儘可能快地處理緩衝區」。試着將其更改爲TRUE，如下所示：

gst-launch-0.10 -v filesrc location=/home/…/miracast_sample.mpeg ! rtpmp2tpay ! udpsink host=localhost port=5000 sync=1 

Answer 2

您是否嘗試過解複用器，然後混流它...

如：

服務器：

gst-launch-0.10 -v filesrc location=file_to_stream.ts ! tsdemux program-number=811 ! mpegtsmux ! rtpmp2tpay ! udpsink host=localhost port=5000 sync=1 

客戶：

gst-launch-0.10 udpsrc port=5000 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)MP2T-ES" ! gstrtpbin ! rtpmp2tdepay ! tsdemux ! mpeg2dec ! ffmpegcolorspace ! autovideosink

我有同樣的問題，因爲你和我的同事建議我在filesrc和rtpmp2tpay之間插入一個tsparse set-timestamps=true。它爲我工作，所以嘗試改變你的管道

gst-launch-0.10 -v filesrc location=/home/…/miracast_sample.mpeg ! \ 
    tsparse set-timestamps=true ! rtpmp2tpay ! udpsink host=localhost port=5000 sync=false
