I am using mpegts.js to play an HTTP-FLV live stream. The stream has no audio, and when I set the video bitrate to 93000kbps, the playback becomes very choppy. I have tried lowering the bitrate to 60000kbps, and the playback is smoother but the quality is not satisfactory. I have also checked my network bandwidth, which seems to be sufficient. I am not sure if there are other parameters I should adjust or if there is a known issue with mpegts.js at this bitrate.
