Hi, I use ffmpeg to receive a live input stream in real time, transcode it and then output it via various live protocols and as an archived mp4 locally. The input data is always received in real time.
Sometimes the live input stream stops sending data for a while but the input stream remains open. Currently when this happens, ffmpeg stops encoding until more data is received from the input stream. I would like a facility in ffmpeg that, when no data is received from the live input stream, it continues to send the last decoded packet of video from the input stream (plus silent audio) to the encoder (in this case for transmission via udp/rtmp/rtsp etc and for local storage as an mp4) with increasing pts/dts as required and with keyframes at the correct interval etc so the stream still decodes correctly for new clients who connect during a period where the input stream is not sending any data. In this case they would see the last frozen frame, then, when data is once again received from the live input stream, it would continue as normal until the next break in transmission and so on. (Sending just the last video keyframe to the client to trigger a frozen image is not acceptable as I need to record an exact copy of the stream in the archived mp4 as it appeared to viewers and that includes any breaks in transmission.) As a bonus it would be nice if there could be a max timeout option after which time the connection is closed if no more input is received from the stream after that time period. I am not capable or competent enough to implement this functionality in ffmpeg myself so I am requesting a time/money quotation from any of you good developers who could take this on.
