[Rohc] rohc performance on lossy media

2018-01-26 Thread mehmet sulak
Hi to all, I am using Rohc comressor/decomressor pair on a lossy media(sometimes at receiver side some packets are lost) and the orderings of the UDP packets are not guaranteed.(packets are not coming in right order all the time). I am using Unidirectional mode and observe some decomression

Thanks for your detailed response first; First I tried method rohc_comp_set_wlsb_window_width(comp,8) by giving 8bits window width but I still observe the following in the log files; rohc_decomp_rfc3095.c:1463 parse_uo0() 4 SN bits = 0xe So I think it still uses 4 bit window length? If yes did

to very small values which stems from loss of initial context packages. The drawback is that 28 byte UDP headers were compressed to 4 bytes previously but with the solution that I tried they are now compressed to 7 bytes. Is this normal behavior? Best Regards.. 2018-01-30 17:26 GMT+03:00 mehmet

[Rohc] use of "Bidirectional Optimistic mode (O-mode)"

2018-03-13 Thread mehmet sulak
Hi to all, I want to use "Bidirectional Optimistic mode (O-mode)" of the rohc library but I could not find enough documentation about how to use. Actually the thing that I wonder is how feedback channel works. How feedback data that is produced in decompressor, is send back to compressor. Do I

to decompressor which is done once? Are there any other differences between O-mode and R-mode? As read from documentation r-mode is still not implemented. Is that true? Is there any plan to implement in the future? Best Regards... 2018-03-13 10:54 GMT+03:00 mehmet sulak <mehmet.su...@gmail.
