| 15:18.38 | mjordan | the cause of the issue in ASTERISK-16804 was an inappropriate use of ast_safe_sleep. It is possible that's the cause here as well, but I don't see that in any of the information so far on that issue |

Right now, however, there aren't any developers actively looking at it. If you'd like to solicit the asterisk-dev list to see if someone would like to fix it that's fine - but barring a patch, there's nothing unfortunately available to test |

| 17:18.52 | mjordan | file: framehooks |
| 17:18.58 | file | YES! hi. |
| 17:19.23 | mjordan | file: without going crazy, it feels like we need to have some way for framehooks to be slightly more intelligent |
| 17:19.39 | file | we need to provide the types of frames a framehook can consume and produce |
| 17:19.42 | mjordan | I hadn't really thought about it with jitter buffers, but calling a jitter buffer twice scares me |
| 17:20.08 | mjordan | that for sure - but even in the case of the jitter buffer, if you ask it for multiple voice frames in a single time slot... eek? |
| 17:20.30 | file | aye |
| 17:21.04 | mjordan | in your case - the thing that prompted this - was that the T.38 gateway frame hook wasn't getting called when a frame was turned into something it needed? |
| 17:21.14 | file | yes |
| 17:21.24 | mjordan | so maybe framehooks should have to "opt in" to being called again |
| 17:21.27 | file | res_fax turns a voice frame into a T.38 control frame |
| 17:22.11 | file | aye, that's an option |
| 17:23.42 | file | hum hum hum |
| 17:37.55 | file | did anyone else hear that Macs now have only a quarter of a thread? the rest are in the cloud |
| 17:38.27 | mjordan | if you have a bad experience with that, it's not your Mac's fault: it's yours. |
| 17:38.55 | mjordan | troll on |
| 17:39.52 | mjordan | ew. |
| 17:42.54 | file | ACHOO! |
| 17:56.31 | putnopvut | So I have a framehook suggestion. Change framehook callbacks to return a value that says "I altered this frame, and therefore I should not be called again". That way, on a re-iteration, you would skip past frame hooks that had already affected the frame. |
| 17:58.37 | file | putnopvut, so a few comments - 1. "the frame" is relative... like at all? 2. keeping track of what has and has not been called is... complicated |
| 18:00.17 | putnopvut | 1) It's at the discretion of the framehook. For a jitter buffer, if it retrieves a frame from the jitter buffer, then it obviously doesn't want to do that again. 2) It's not that complicated. |
| 18:01.04 | file | so just a - once I'm called never call me again? |
| 18:01.40 | putnopvut | on this read/write operation, yes. |
| 18:01.49 | file | nods |
| 18:02.13 | file | how would you keep track? |
| 18:04.51 | putnopvut | In the function that iterates over the list of framehooks, create an array that is the same size as the framehook list. When iterating over the framehooks, keep a counter of what framehook you are on, and if the framehook gives the return stating that it shouldn't be called again, then set that spot in the array to true. |
| 18:05.30 | file | ah clever |
| 18:05.31 | putnopvut | in any iteration, the array at the counter's index is true, then just continue on to the next framehook immediately. |
| 18:06.34 | putnopvut | THe only tricky bit is sizing the array correctly. |
| 18:07.07 | file | either have to keep the count, or calc on entry |
| 18:07.32 | file | erm... grow it on the first iteration |
| 18:07.37 | file | or, rather |
| 18:07.46 | putnopvut | framehook_list struct could keep a count. |
| 18:08.23 | file | aye |
