HD videos buffering question

discuss4u · 2013-06-10 13:02:43

I found that it takes something like 13s for the HD mp4 to start to play. Is there any way to shorten the duration?

When it is a normal flv, it can start player in no time. And it can be player smoothly. I have checked two videos. One flv and one mp4, both are of similar length but the flv file is around 40% bigger in size. Yet, the flv can still play very smoothly without the need to wait for buffer. So, I suppose the mp4 can also be played very smoothly with a very short buffering time.

I have tried to put a smaller number for buffer length in player but it seems that there is no change.

You can fine tune that in lighttpd/nginx/apache configuration for the h264 streaming module.

Thanks symtab. I use nignx. Do you mean the setting of mp4_buffer_size and mp4_max_buffer_size. I have tried to play around with them but there is not much difference for the mp4 to be buffered and start on front end.

Is it related to the metadata of the mp4 file?

Hmmm...did you restart nginx after you changed these settings? Yes, its related to the metadata (however if the metadata is not correct, then the file wont play unless its loaded completly...so not the metadata is the problem).
