Real time livestreaming - RPI
24 avril 2022, par VictorI work at a telehealth company and we are using connected medical devices in order to provide the doctor with real time information from these equipements, the equipements are used by a trained health Professional.


Those devices work with video and audio. Right now, we are using them with peerjs (so peer to peer connection) but we are trying to move away from that and have a RPI with his only job to stream data (so streaming audio and video).


Because the equipements are supposed to be used with instructions from a doctor we need the doctor to receive the data in real time.


But we also need the trained health professional to see what he is doing (so we need a local feed from the equipement)


How do we capture audio and video


We are using ffmpeg with a go client that is in charge of managing the ffmpeg clients and stream them to a SRS server.
This works but we are having a 2-3 sec delay when streaming the data. (rtmp from ffmpeg and flv on the front end)


ffmpeg settings :


("ffmpeg", "-f", "v4l2", `-i`, "*/video0", "-f", "flv", "-vcodec", "libx264", "-x264opts", "keyint=15", "-preset", "ultrafast", "-tune", "zerolatency", "-fflags", "nobuffer", "-b:a", "160k", "-threads", "0", "-g", "0", "rtmp://srs-url")



My questions


- 

- Is there a way for this set up to achieve low latency (<1 sec) (for the nurse and for the doctor) ?
- Is the way I want to achieve this good ? Is there a batter way ?

Display formatted date and time over frames using ffmpeg
28 août 2020, par marcmanI've gone through a handful of questions on here (this, this, this, etc) concerning overlaying the date and time on videos using ffmpeg, but I haven't been able to figure out the solution.


I personally have found the ffmpeg documentation difficult to parse as well regarding drawing text that updates every (N) frame(s).


I have the exif data from a movie specifying when it was created. I'd like to be able to emblazen that over the movie (as though it were a home video from some old VHS tape). For example, let's say I have a video from January 2, 2012 at 10:33:53. I'd like to be able to show "Jan 2, 2012 10:33:53am" on the lower right in white text. The spatial positioning and color are clear to me, but just how to go from the timestamp information I have to the formatted expansion is proving to be quite difficult for me. I have succeeded in getting a clock starting from 00:00:00.00 and counting up (using
timecode
andtimecode_rate
), but unfortunately I can't get much more than that.

My question is : what is the proper
datetext
command that will allow me to both (a) provide the start time, and (b) format it with the proper expansion.


As a bonus, if you can also point me to how to do this using the wonderful ffmpeg-python library, it would be even better. That library is quite good, but it does not appear to be actively maintained anymore.

How can i add audio at specific time/Frame in FFmpeg ?
22 décembre 2023, par Mickey SI have audio that i am adding (without Re-encode) in mute video file, in starting i have intro which has no sound and i want to add audio file after that time/frame , after searching so hard i only found this command useful,

ffmpeg -y -i file.mp4 -itsoffset 00:00:05 - i file.wav -map 0:0 -map 1:0 -c:v copy -preset ultrafast -async 1 out.mp4


it does the job but the problem is , its not precise , it is kind of mismatch because audio is supposed to be starting at 4.840 seconds but its not possible with this command, please suggest me something to solve my problem :(


Thanks


I tried on Reddit, various command site etc.
