[Ekiga-devel-list] video decoding debug

[André Abrantes <andreadps gmail com>]

Hello there.

I have been working with Ekiga for quite some time and now I am
testing how it handles video calls coming from different environments
via Asterisk. But let's not focus on that right now.

Using wireshark I can see a nice H.264 flow coming from Ekiga to
Asterisk. The opposite flow seems somewhat awkward...
Anyways, I have checked Ekiga debug level 5 and have found some clues
like these:

2, final statistics:
    packetsSent       = 699
    octetsSent        = 475271
    averageSendTime   = 38
    maximumSendTime   = 115
    minimumSendTime   = 0
    packetsReceived   = 107
    octetsReceived    = 12614
    packetsLost       = 0
    packetsTooLate    = 0
    packetOverruns    = 0
    packetsOutOfOrder = 0
    averageReceiveTime= 194
    maximumReceiveTime= 238
    minimumReceiveTime= 146
    averageJitter     = 26
    maximumJitter     = 32

Somehow, we are receiving media packages but, at the end of the call,
the decoder says it has not decoded any frame.

So, does anyone know a way for me to debug ekiga/opal/x264 to find why
H.264 frames are not getting decoded?
