Q: Is it possible to loop a video?

[rodolfoap]

I need to loop small video files continuously. How can I do that (for what I've read, pipelines would not allow looping)? Thanks in advance...

[Ullaakut]

🤔 Looping videos forever is actually the default behavior when using a file input.

EDIT: I misunderstood this as a bug report and not a question, my bad. Just in case it's actually a bug report (if not, disregard these instructions):

Some RTSPATT streams have been running 24/7 since 2017 so I find it strange it would be an issue in the software, but just in case, could you add the following information to this ticket:

• Command line you ran to launch RTSPATT
• Logs of RTSPATT
• Information on the video you are streaming (encoding, length, size, framerate and resolution if possible)
• Re-run RTSPATT but add the following argument -e GST_DEBUG=3, paste those logs into a pastebin and add a link to the pastebin in the issue

If you do all that, I should be able to understand better what the issue is, and if it's a bug in RTSPATT, to reproduce it and fix it 🙏🏽

I encounter this too.here's my info.sorry, it's a bit mess.

1. docker run --rm -e GST_DEBUG=3 -e INPUT="/tmp/video.mp4" -e RTSP_PORT=18554 -e GST_PIPELINE="filesrc location=/tmp/video.mp4 ! qtdemux ! video/x-h264 ! rtph264pay pt=96 name=pay0" -v "$PWD/test.mp4:/tmp/video.mp4" -p 18554:18554 ullaakut/rtspatt

@Ullaakut thanks for your great work!

Is it possible to not loop? You said looping was the default behaviour but I'm not sure where to override this.

The desired behaviour would be to play one iteration of the input video file and then terminate at the end of the video. Is there an option for this?

[Ullaakut]

Hi @lukeweston !

With the current pipeline, no there isn't. At the moment my only suggestion would be to use a custom pipeline to achieve this, but it requires knowledge of gstreamer unfortunately.

I'm currently planning on making a version 2.0 of rtspatt in go, so that might be one of the features I add in this next version. I'll make sure to update this issue if that's the case, in order to let you know about it.
