[..]</pre> <pre> d. ! video/x-raw ! queue ! x264enc ! [..]</pre> On a separate note, on a jetson xavier you should be able to use nvidia's hardware encoders, eg nvv4l2h264enc, not sure where the source for those elements lives but their existence is documented in <a class="moz-txt-link-rfc2396E" href="https://developer.download.nvidia.com/embedded/L4T/r32-2_Release_v1.0/Accelerated_GStreamer_User_Guide.pdf"><https://developer.download.nvidia.com/embedded/L4T/r32-2_Release_v1.0/Accelerated_GStreamer_User_Guide.pdf></a> <div class="moz-cite-prefix">On 12/23/20 2:54 AM, KN wrote: </div> <blockquote type="cite" cite="mid:1608688453141-0.post@n4.nabble.com"> <pre class="moz-quote-pre" wrap="">I am learning about GStreamer, and I have trouble putting together a basic MPEG-TS to MP4 code.

I think I am close but something is off. I suspect I should not have theoradec and oggdemux ... but confused what it needs to be) (note: I am running on Jetson Xavier thus need to stay away from omxh264enc, etc).
