Hi, Please try with the following setting first: - frm_per_pkt = 1 - VAD disabled make sure everything ok with this setting, then move on with frm_per_pkt = 2, if everything ok then deal with VAD enabled. Some notes about the code: - in encode(), it seems you ignore the first byte output of VoiceAge G729 encoder. If that first byte contains frame type info, it shouldn't be ignored, especially when VAD is enabled, since the encoder may return SID (silence frame) or DTX (discontinuous transmission) or speech frame. If you treat SID and DTX frame as speech frame, decoder may fail or produce noise. - silence detector is unnecessary since G729 already has built-in VAD. - in encode(), the pcm_in += 2*SAMPLES_PER_FRAME, shouldn't it be just pcm_in += SAMPLES_PER_FRAME? - in decode(), it doesn't seem that SID frame is handled very well: if (input->size < L_PACKED_G729A) return PJMEDIA_CODEC_EFRMTOOSHORT; Again, if the first byte actually specifies the frame type, instead of returning non-PJ_SUCCESS it should be decoded normally (e.g: with first byte/frame type = SID) Regards, nanang On Fri, Sep 5, 2008 at 7:30 PM, Sebastian Groosman < Sebastian.Groosman at indicia.nl> wrote: > Hi, > > I've had the problem that no sound was heard at all with the VoiceAge > G729 libs. > It appeared that for the decoding part I needed a local buffer and > prepend it with a "2". > For the encoding the output buffer and size were the problem. > Both these problems are mostly solved now.
