- Added support for limiting concurrent transcoding operations in the media API to prevent resource exhaustion. - Implemented functions to retrieve video duration and bitrate using ffprobe for improved streaming performance. - Enhanced the generate_transcoded_stream function to handle HTTP range requests, allowing for more efficient video playback. - Updated VideoModal component to disable fluid and responsive modes, ensuring proper container boundaries during video playback. - Improved logging throughout the transcoding process for better error tracking and debugging.
