Fix: In gstreamer x264enc dynamic parameter change
In GStreamer, you can change parameters dynamically in the x264enc element to control the encoding process for H.264 video. To change parameters during runtime, you need to use GStreamer's capabilities for dynamic pipeline modification. Here's how you can do it: 1. **Create Your GStreamer Pipeline**: First, set up your GStreamer pipeline with the x264enc element and other necessary components. For example: ```shell gst-launch-1.0 videotestsrc ! x264enc ! autovideosink ``` 2. **Access the x264enc Element**: To dynamically change x264enc parameters, you need to access the x264enc element within your GStreamer application code. You can do this using GStreamer's APIs in C or another language that supports GStreamer bindings. 3. **Modify Parameters**: You can change various parameters on the x264enc element dynamically. For instance, you can adjust parameters like the video bitrate, keyframe interval, profile, preset, and tuning during runtime. You need to set
