nvh264enc - Requested stream size is larger than the maximum configured size

[Sid Sethupathi]

I'm trying to transcode a 4K RTP MPEG-TS and keep running into this issue.

> INFO  videodecoder gstvideodecoder.c:1330:gst_video_decoder_sink_event_default:<video_decoder> upstream tags: taglist, video-codec=(string)"H.264\ \(Main\ Profile\)", minimum-bitrate=(uint)418000, maximum-bitrate=(uint)70234400, bitrate=(uint)28947228;

I tracked the error down down these lines but I'm not sure how to resolve: https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/blob/ac690978f29c7addb90908fe2d597e8f8e0ba2b8/sys/nvenc/gstnvh264enc.c#L506-512

Using gst-launch-1.0 and videotestsrc, I'm able to encode a 3840x2160 stream so I don't understand why the encoder complains about a maximum size in my dynamic pipeline.

"gst-launch-1.0 -v videotestsrc ! "video/x-raw,framerate=(fraction)50/1,width=(int)3840,height=(int)2160,format=(string)I420" ! nvh264enc ! filesink location=testsrc.mp4"

Thanks,

Sid
