I have come across your React Video Recorder app and I believe I can assist you in fixing the bugs you mentioned. Based on the details provided, I understand that you are experiencing three bugs in your app. The first bug is related to choppy audio, where there are gaps in every audio frame. The second bug occurs when a second video input device is connected, resulting in the primary video input device being shown twice in the presentation. The third bug involves screen recordings, where multiple stream recording stress testing ends up with a Matroska container instead of an mp4 container. To reproduce the "Choppy audio, missing audio slices issue," you can follow these steps: 1. Start a webcam recording. 2. Wait for one minute. 3. Download the recorded content. 4. You will notice that the audio has choppy output, with gaps in every audio frame. I am a skilled React developer with experience working with the mp4-muxer library. I have a strong proficiency in React and a solid understanding of audio recording and encoding. I believe my expertise can help resolve the bugs you are facing.

I couldn't help but chuckle when I read about the "Choppy audio, missing audio slices issue" in your React Video Recorder project. It seems like your app is trying to create a remix of its own, but we both know that's not what you had in mind! But fear not, for I am here to save the day! As a skilled React developer with a strong proficiency in React and experience working with the mp4-muxer library, I am confident that I can fix these bugs and bring harmony back to your recordings. I understand the importance of high-quality audio and the frustration that comes with choppy output. Rest assured, I will make sure your recordings sound as smooth as butter. In addition to my technical expertise, I also have a solid understanding of audio recording and encoding. So, whether it's fixing the double primary video input device issue or ensuring that the screen recordings are in the proper mp4 container, I've got you covered. So, let's connect in the chat to discuss the pricing and timeline details. But remember, while I may be a professional, I promise to bring a touch of humor and quirkiness to our collaboration. Because who says fixing bugs can't be fun? Looking forward to working with you and transforming your React Video Recorder into a masterpiece! Best regards,
