| 00:22.11 | DocScrutinizer05 | SIP presence is a non-satndard SIP extension. Video: I never seen it working but that's mainly been for lack of support by my service provider, anyway I never seen maemo SIP UI quit on trying video |
| 00:23.15 | DocScrutinizer05 | possibly the service provider sends a BYE to you when you announce you want to initiate/chnage-to a *video* session |
| 00:25.20 | DocScrutinizer05 | again ethereal is your friend, check the Session Description and which codecs are offered/requested and what's the response |
| 00:25.54 | DocScrutinizer05 | ethereal even has very nice dissectors for all that stuff |
| 00:26.13 | DocScrutinizer05 | almost self explanatory |
| 00:28.17 | Juest | Linphone does video, tested already. |
| 00:28.42 | Juest | Just with her, Jingle and SIP video /does not work *at all* / |
| 00:30.23 | DocScrutinizer05 | you *might* be interestef in this little cmdline hack: http://talk.maemo.org/showthread.php?p=1022444 - take care to apply a filter for the ethereal traffic when you use this (modified for WLAN instead ISI) to monitor the VoIP traffic. Otherwise you get an avalanche of self referential logging |
| 00:31.14 | DocScrutinizer05 | again, this is no help channel for linphone |
| 00:31.25 | Juest | Not asking linphone help :| |
| 00:31.31 | Juest | but video call help |
| 00:31.37 | DocScrutinizer05 | neither jingle |
| 00:33.14 | DocScrutinizer05 | all relevant data for maemo SIP video can get gathered by using ethereal on device as suggested above |
| 00:33.58 | Juest | wireshark-like ? |
| 00:34.18 | DocScrutinizer05 | ethereal/wireshark, I forget which is the recent name |
| 00:35.01 | DocScrutinizer05 | prolly wireshark, yes |
| 00:35.23 | Juest | aka you're telling us to capture the "event" |
| 00:35.40 | DocScrutinizer05 | if you want to put it that way, yes |
| 00:36.32 | DocScrutinizer05 | the only effective way to debug SIP issues is to look what's going on on SIP protocol level |
| 00:38.19 | Juest | Voice calls work great, the issue is when any video is attempted it just stops responding |
| 00:38.39 | DocScrutinizer05 | when your client receives a session description that's not compliant with its capabilities, or when other end sends an error because of similar problem there, then the session will abort. That's normal |
| 00:39.05 | DocScrutinizer05 | yes, understood. Sesion Descriptions differ between voice calls and video calls |
| 00:40.30 | DocScrutinizer05 | when you switch on video, the client tries to negotiate a new session (description) with far end |
| 00:40.52 | DocScrutinizer05 | since a new RTP channel and a associated video codec is needed |
| 00:41.03 | Juest | i do not even receive video calls |
| 00:41.21 | DocScrutinizer05 | en passant a new audio channel description mightt get negotiated too |
| 00:41.56 | DocScrutinizer05 | sorry, I don't understand what you meant by >>i do not even receive video calls<< |
| 00:43.44 | Juest | Anything that involves video calls = doesnt work properly |
| 00:45.04 | DocScrutinizer05 | and I explained above WHY that might be the case |
| 00:45.37 | Juest | Jingle barely worked, Skype on maemo crashes when video is attempted and i never receive a sip video call and if its attempted mid-call the call dies |
| 00:45.43 | DocScrutinizer05 | so either you want to check if we can find the reason and possibly fix it, or you contine to state "video doesn't work" and I'm out |
| 00:47.20 | DocScrutinizer05 | please understand that it's worth nothing in this context to list what works or doesn't work |
| 00:48.09 | DocScrutinizer05 | the only way to takle this is looking at either error logs or traffic dump |
| 00:48.12 | Juest | didnt you just said you didnt understand? |
| 00:48.16 | Juest | Okay |
| 00:48.24 | Juest | i'll do that |
| 00:49.01 | DocScrutinizer05 | alas maemo telepathy logs are pathetic at best, rather non-existent at all |
| 00:49.16 | DocScrutinizer05 | so your best chance is wireshark |
| 00:51.46 | DocScrutinizer05 | suspects that maemo only offers h.263 video codec and that might not be very popular and commonly supported anymore |
| 00:52.08 | Juest | umm, Jingle and Skype are on H264.... |
| 00:52.42 | DocScrutinizer05 | so unless far end offers same h.263 codec, a video call will fail (if the assumption is corect) |
| 00:53.35 | DocScrutinizer05 | N900 only can do 'low profile' video on the h.26x codecs |
| 00:55.38 | DocScrutinizer05 | err maybe it's called baseline profile |
| 00:56.20 | DocScrutinizer05 | H.254 Baseline Profile (BP): Primarily for lower-cost applications with limited computing resources, this profile is used widely in videoconferencing and mobile applications. |
| 00:56.32 | DocScrutinizer05 | H.264 even |
| 00:57.15 | Juest | And Skype shouldnt crash on video then -_- |
| 00:57.42 | DocScrutinizer05 | aha |
| 00:58.01 | DocScrutinizer05 | Skype crashes too? |
| 00:59.11 | Juest | As soon she taps Camera = "boom" literally |
| 01:00.03 | DocScrutinizer05 | when SIP and Skype both crash, odds are it's either both 'protocols' switched from H.263 / H.254 base line to more CPU power demanding codecs during the last 6 years, or your device's DSP is defect on a hw level |
| 01:00.49 | DocScrutinizer05 | dang, s H.254 H.264 |
| 01:02.34 | DocScrutinizer05 | though the user agents /clients should handle a "codec not supported" gracefully, falling back to audio-only and possibly even telling in plaintext why video isn't possible. a crash would suggest sth is odd on hw level. maybe a peek into syslog could help reveal the root cause |
| 01:03.38 | DocScrutinizer05 | I wonder if video recording still works on same device where video calls crash |
| 01:04.17 | DocScrutinizer05 | ooh ugh! is the device overclocked? |
| 01:05.01 | Juest | in summary: Jingle barely works, SIP video calls do not function at all (call ghosts on my side and ends on her side if video activated mid-call and i never receive a call if she tries to video call from the start) and Skype crashes on her side on any attempt to send video |
| 01:05.21 | DocScrutinizer05 | or rather: has it been used in overclocked mode for extended periods of time? |
| 01:07.57 | DocScrutinizer05 | reportedly the DSP which does the H.26x encoding is particularly prone to wearing out permanently and then crashing when operated in overclocked mode |
