How to add Resolution and dynamic bitrare option in Pipeline

[parthjenex]

Hello Everyone,

I have compiled and built the code for my Jetson Orin device.
Per my current requirement, I want to add resolution and dynamic bitrate in the pipeline.

for that I have changed the pipeline of this https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/blob/main/samples/kvsWebrtcClientMasterGstSample.c file in the case RTSP source of PVOID sendGstreamerAudioVideo(PVOID args) function
and added resolution parameter. after changing the final pipeline, it looks like this.

case RTSP_SOURCE: {
UINT16 stringOutcome = snprintf(rtspPipeLineBuffer, RTSP_PIPELINE_MAX_CHAR_COUNT,
"uridecodebin source::latency=0 uri=%s ! "
"nvvidconv ! "
"videoconvert ! "
"videoscale ! video/x-raw,width=256,height=144 ! "
"x264enc bframes=0 speed-preset=veryfast bitrate=100 byte-stream=TRUE tune=zerolatency ! "
"video/x-h264,stream-format=byte-stream,alignment=au,profile=baseline ! queue ! "
"appsink sync=TRUE "
"src. ! audioconvert ! "
"audioresample ! opusenc ! audio/x-opus,rate=48000,channels=2 ! queue ! "
"appsink sync=TRUE ",
pSampleConfiguration->rtspUri);
if (stringOutcome > RTSP_PIPELINE_MAX_CHAR_COUNT) {
printf("[KVS GStreamer Master] ERROR: rtsp uri entered exceeds maximum allowed length set by RTSP_PIPELINE_MAX_CHAR_COUNT\n");
goto CleanUp;
}
pipeline = gst_parse_launch(rtspPipeLineBuffer, &error);
break;
}

after building and compiling the SDK when I ran the executable I got this error
Opening in BLOCKING MODE NvMMLiteOpen : Block : BlockType = 279 NvMMLiteBlockCreate : Block : BlockType = 279
attaching a log file for better reference
log.txt

so my question is how can I change the pipeline to get my desired resolution and allow dynamic bitrate ?
