On the Jetson you need 4 byte formats like BGRx. The problem I tried to solve is that GRAY8 was in your code before BGRx , so it always connected GRAY8 first, instead I want it to choose BGRx first, and actually I don’t care about GRAY8. So I need this change for my caps to work and if from your point of view it does not change your logic then I strongly suggest to keep my changes. By the way your standard pipelines are also not working on the Jetson ;-). Regards ***@***.*** [16054.png] HINWEIS: Diese Nachricht (inklusive aller Anhänge) ist vertraulich.

The order change in if-else-if-else chain does not change logic. I propose to revert it.

{ //do not emit signals: all calls will be synchronous and blocking gst_app_sink_set_emit_signals (GST_APP_SINK(sink.get()), FALSE); - caps.attach(gst_caps_from_string("video/x-raw, format=(string){BGR, GRAY8}; video/x-bayer,format=(string){rggb,bggr,grbg,gbrg}; image/jpeg")); It breaks grayscale streams. I propose to try: caps.attach(gst_caps_from_string("video/x-raw, format=(string){BGR, BGRx, GRAY8}; video/x-bayer,format=(string){rggb,bggr,grbg,gbrg}; image/jpeg")); — Reply to this email directly, view it on GitHub<#25557 (review)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/AB4YPEEW5V7N3UIGLD5CVNTZBD2AHAVCNFSM6AAAAABHLE2BKSVHI2DSMVQWIX3LMV43YUDVNRWFEZLROVSXG5CSMV3GSZLXHMZDANBTGU3TMMZXGA>.
