Subtitles - Stream - "On the fly"
Locked

This post was updated on .
My will is to send subtitles "live" from my "server" to "client".
Among with my video. (My Pipeline is at the end of this message). 1. I would like to generate subtitles on my "server". The context of the subtitles will be in a file called, MY_FILE.TXT with data (GPS and accelerometer info). That will refresh every few seconds. 2. send the subtitles sync ( if possible) with my video, and display/ save them on my "client". Any kind of help, solution, idea, will be great. My goal is to sand data (GPS) from my server --> client, synced with the video. So later I can read this data. So I don't want to "burn" that data on the video, just send it as a separate file. My current video pipeline is: "Server" gst-launch v4l2src always-copy=false ! 'video/x-raw-yuv,format=(fourcc)UYVY,width=640,height=480,framerate=25/1' ! TIVidenc1 codecName=h264enc engineName=codecServer ! rtph264pay pt=96 ! udpsink host=192.168.1.100 port=4000 "Client" gst-launch-0.10 -v udpsrc port=4000 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)\"Z0KAHukBQHpCAAAH0AAB1MAIAA\\=\\=\\,aM48gAA\\=\"' ! \ rtph264depay ! ffdec_h264 ! xvimagesink sync=false Thanks ! |

You will need to send the subtitle as an extra rtp stream, but we don't have payloaders/depayloader for it. Seem there is something called RTP payload format for Timed Text (TTXT). Maybe you can do some research and file a bug.My will is to send subtitles "live" from my "server" to "clinet". among with my video.
