The encoded data size if set to single NAL mode (default) should not exceed the maximum UDP packet size of 1.4Kb less RTP over head so 1.2Kb should be ok. There should be no fragmentation and only 1 frame per packet. Clearly there is a bug in the encoder. Perhaps it is sending in non-interleaved mode (fragmentation allowed) and not it single NAL. Mirial only supports Single NAL.

Hi All,

For the libx264, It directly fragment the encoded data if it larger than the maxpayloadsize (1.4KB by default).

If I had encoded data 5.6K. Then, it will fragment and sent out, 4 times.

Is it comply to H.323 standard?

Because currently other voip (polycom, Mirial...) can't display my encoded data size greater than 1.4K.

Thanks.
