[FFmpeg-user] Is there any reason that MAX_PES_PAYLOAD value is defined 200K

[KimWoon-Kyong]

In libavformat/mpegts.c#define MAX_PES_PAYLOAD 200*1024
Is there any reason that MAX_PES_PAYLOAD value is defined 200K?In mpegts, the picture is split when picture size is over 200k.But my H/W decoder can't decode split picture.After setting MAX_PES_PAYLOAD as 400k, there's no split picture.
Please tell me why MAX_PES_PAYLOAD value is 200K
