 I am using ffmpeg for live stream processing. Basically, I compiled ffmpeg
 myself. Unfortunately, I notice that when the bitrate gets a bit high (>
 15mbps H264), the decoding can not keep up with the incoming rate. I
 wonder the rate is not still very high.

 I wonder, is there any flags to set, or maybe some tips to make ffmpeg
 decode faster or more efficient with live decoding? Or is there any flags
 that I can turn on? Like multi-threading? It's running/should run on CPU.
 But CPU usage is still not maximum.

 We are running ffmpeg from C API as the base for the processing. Here is
 the sample .ts file that stalls the processing.
