Theora w/ farsight2
Locked
 
|
Hi,
I am using Theora codec w/ farsigh2 (no Telepathy) for video conferencing and I am facing distorted video on the receiving end when using camera with relatively high resolution on the sending end. Low resolution streams are decoded alright by the receiver. I ran receiver/sender on the same host so the bandwidth should not be a problem. CPU consumption was low too. The artifacts in the video I see most often are small squares(up to 16x16 or so pixels) with 2 white and 1 black stripes in it. Here is versions of the gstreamer/farsight2 I am using: set VER_GST=0.10.25 set VER_GST_PLUGINS_GL=0.10.1 set VER_GST_PLUGINS_BASE=0.10.25 set VER_GST_PLUGINS_GOOD=0.10.17 set VER_GST_PLUGINS_UGLY=0.10.13 set VER_GST_PLUGINS_BAD=0.10.17 Farsight2 0.0.16 I read on this list about incompatibilities between certain versions of the Fs and gstreamer. I wonder if I am running in it here or it is something else.

Hi, I updated to Farsight2, 0.0.20 set VER_GST=0.10.29 set VER_GST_PLUGINS_BASE=0.10.29 set VER_GST_PLUGINS_GOOD=0.10.22 But I am still getting distorted video when Theora codec is used. Looks like frames between I-frames are not properly decoded. Anything I can check?

Hi,
My problem seems to be related to Theora encoder. With the number of discontinued buffers increasing I am likely to get distorted image on the receiving end: 0:01:55.343750000 4492 00DF2698 DEBUG theoraenc gsttheoraenc.c:829:theora_enc_is_discontinuous:<theoraen c4> Incoming TS 0:01:50.345187500 exceeds expected value 0:01:48.955312500 by too much, marking discontinuity If I increase threshold for late/discontinued buffers - the receiving end shows video w/o artifacts. I am not sure yet how to interpret the observation because I see discontinued buffers in this pipeline which still produces the fine video: gst-launch --gst-debug="theoraenc:5" dshowvideosrc!ffmpegcolorspace!theoraenc!theoradec!ffmpegcolorspace!directdrawsink One more thing - on every discontinued packet, the theora codec is deallocated and reincarnated again by theora_enc_reset(). For performance sake it looks suspicious to me. Thanks, Miron > > Hi, > > I updated to Farsight2, 0.0.20 > set VER_GST=0.10.29 > set VER_GST_PLUGINS_BASE=0.10.29 > set VER_GST_PLUGINS_GOOD=0.10.22 > > > But I am still getting distorted video when Theora codec is used. > > Looks like frames between I-frames are not properly decoded. > > Anything I can check? > > Thanks, > Mironoz > > > > > Hi, > > > > I am using Theora codec w/ farsigh2 (no Telepathy) for video conferencing and I am facing distorted video on the receiving end when using camera with relatively high resolution on the sending end.

Hi ,
Use "sync=false" property with both the sinks at sending and receiving end , and then see the behaviour .

Hi, All my video/audio sinks on receiving end have sync=false. The sending part is handled by Farsight2 and it looks like sync=false is set there too.

Hi,
So I came to the conclusion that latency caused by encoder and network are destroying my Fs2/Theora video on the receiving end. With high (for ex 1/15) fps encoder drops many buffers and does not try to lower fps to adjust to CPU capabilities.

Hi,
can you monitor a session with wireshark on the receiving side and check the lost packets? When bandwidth usage increases you're more likely to loose packets or receive them too in late.
