Gstreamer udpsrce using Gopro H10 livestream - invalid RTP payload

[heythere]

Trying to decode a live stream from a gopro hero 10 using gstreamer but whilst it opens fine using openCV or vlc, I can’t seem to get gstreamer to decode the feed:

“WARNING: from element /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0: Could not decode stream.
Additional debug info:
gstrtpbasedepayload.c(466): gst_rtp_base_depayload_handle_buffer (): /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0:
Received invalid RTP payload, dropping
0:00:04.469022853 10663 0x55917a2770 WARN rtpbasedepayload gstrtpbasedepayload.c:466:gst_rtp_base_depayload_handle_buffer: warning: Received invalid RTP payload, dropping”

I got the above using:

gst-launch-1.0 -v udpsrc port=8554 ! “application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96” ! rtph264depay ! h264parse ! decodebin ! videoconvert ! autovideosink sync=false

Any pointers in the right direction would be appreciated.

Hi,
Please make sure the protocol is UDP. If it is valid source, this command should work:

$ gst-launch-1.0 -v udpsrc port=8554 ! "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! fakesink

The error shows it cannot get valid h264 stream. Another possibility is the source is encoded into h265 stream or other type.

Hey @DaneLLL thanks for the reply!

using the aformentioned, it hangs after the following:

gst-launch-1.0 -v udpsrc port=8554 ! “application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96” ! fakesink

Setting pipeline to PAUSED …
Pipeline is live and does not need PREROLL …
Setting pipeline to PLAYING …
New clock: GstSystemClock
/GstPipeline:pipeline0/GstCapsFilter:capsfilter0.GstPad:src: caps = application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96
/GstPipeline:pipeline0/GstFakeSink:fakesink0.GstPad:sink: caps = application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96

So then I checked the stream in vlc, and got the following codec information: Imgur: The magic of the Internet

"Codec: H264 - MPEG-4 AVC (part 10) (h264)"

which lead me to this post explaining that I need to demux a MPEG-TS stream using “tsdemux”.

After a bit more fiddling, landed on:

"gst-launch-1.0 -v udpsrc port=8554 ! tsdemux ! decodebin ! autovideosink fps-update-interval=1000 sync=false "

The video plays through pretty cleanly now.

I have to set sync=false otherwise it came through quite pixelated and in strange field orders.

Any reccomendations to improve please let me know, new to gstreamer so keen to learn better processes.
