I apologize for the long email. I'm not very good at explaining details like this clearly in a quick way. Thank you for taking the time to read it and to reply. You saved me a lot of time by preventing me from continuing to try to figure out what I was doing wrong, and I was able to work around it fairly easily by saving the first access unit and first decoded frame, and continuing to pass the first Au to the library until it produced the first frame, in order to flush out whatever is internally buffered.

Your email is long but at least clear. The way the decoder is working is like a FIFO there is no way to get this picture back except by sending more pictures to the decoder to get this picture back. You need to get one to get one more picture. Sorry this is the current behaviour of the decoder.

Hello, OpenSVC is working well for me, but I have a question about one detail of the usage: Say my video is encoded with only one layer with the GOP structure IbBbPbBbPbBb I... and 32 frames. The access units will arrive from the encoder / be in the file in the encoding order of IPBbb... So I pass the first I frame (access unit) to the decoder, and the library returns that it has produced a picture, and I can write the first frame to a .YUV file, great. But then, 2nd frame in display order is a b frame. Of course that can't be decoded and written to file, first the P and B frames on which it may depend must be decoded. So the P frame (access unit), as the next frame in the file/bitstream, is passed to the Decoder. Of course the library indicates that it does not have a picture ready, since frame 2 has not yet been received. Several more frames are passed to the decoder, without a picture being returned, as expected. After a few frames, say once the P and B frames have been passed, and the next b frame is passed, the library indicates that a picture is ready, and we can now write the 2nd frame. Each frame after that returns a picture, as enough is buffered internally (perhaps my understanding of how this works is completely wrong...). So everything is great, the first 26 or so frames in the decoded yuv match the reference yuv from the encoder perfectly. But then we reach the end of the file/bitstream. There are still 6 or so frames at the end of the reference .yuv file. But there are no more frames left in the .264 to pass to the library. It seems that the internal buffering for dependant pictures leaves the last few frames internally buffered with no way to get them out. It seems that the return of the library is a list of .yuv pictures, however, the size of that list is always 1. It would make sense if that list were bigger, returning all the buffered frames at the end of the video. However, the only way to tell the library that it is the end seems to be to call SVCDEcoder_close, but that doesn't produce the last frames. Even if my GOP structure is IPPPP.... it seems to produce the same results, which is strange since I would expect the library to be able to return a picture for every frame in that case. Is there a way to use the library to produce every last frame from the .264 file, and I am just using it wrong? Or are a few frames always lost to internal buffering? I don't see what I am doing differently than MPlayer, but there is probably something I am doing wrong. It is quite important to me that I be able to decode every frame, so any help with this last detail would be greatly appreciated. Thank you, Brett Slote |

hi, I tried to install open svc decoder using Mplayer. However, I would like to achieve streaming (so tried to configure the Mplayer with live). Currently, I am using ubuntu 10.10 version. I have downloaded live555 and extracted in /usr/lib. Then used genmakefile <OS> to generate make file and could successfully install live555. Then, I tried to generate make file for Mplayer using configure command ./configure --enable-svc --enable-gui --enable-live I have encountered the following error, libmpdemux/demux_rtp_internal.h:33: fatal error: liveMedia.hh: No such file or directory compilation terminated. make: *** [libmpdemux/demux_rtp.o] Error 1 can any one help me in this issue?

Dear Chenghsin,
Sorry to answer you so late.
DisplayOrderSVC() is in charged to select the next frame to display.
It searchs from buffured pictures the best one of the right layer.
nb_img_display is the number of frames to bufferize into to be sure to
display all frames in the right order.
It's computed according to encoding parameters (level, dpb size ...).
The if case, you were talking about is used t know if enough frames have
bufferized. It could be simplified by Mmo -> num_free_poc_address == 0.
Regards,
Médéric

Greetings,
I like to thank all the developers for their contributions toward this
wonderful software.
I'm reading some of the opensvc code, in particular, I like to
understand how does DisplayOrderSVC() work. I'm not following the
if-clause quoted below. Why do we want to check if nb_img_display -
num_free_poc_address >= nb_img_display?
//Detect if we have waited enough decoded frame except for the
first frame.
if (Nal -> DqIdMax == Nal -> DqId && ((Mmo -> nb_img_display -
Mmo -> num_free_poc_address >= Mmo -> nb_img_display)
|| (!Mmo -> LayerMMO [0] . num_decoded_frame))){
SearchFrameToDisplay(Nal, Mmo, x_size, y_size, Crop,
ImgToDisplay, address_pic);
}else{
.......
}
Also, I'm guessing nb_img_display is the number of frames in the
current GoP. Am I right?
Any hints are highly appreciated.
Best regards,
Chenghsin

To get cgs only you need to put the same resolution in both layers (with different bitrates). The command to change from one layer to another layer is the same as below.

Hi everyone!
Probably this is not the best place to post a question again about cfg used
to enconde a video. However I guess someone of you could know the answer.
In the JSVM manual I saw this video that after been analyzed with
BitStreamExtractorStatic we can see this:
> BitStreamExtractorStatic input.svc
Layer Resolution Framerate Bitrate DTQ
0 176x144 3.7500 106.00 (0,0,0)
1 176x144 3.7500 206.00 (0,0,1)
2 176x144 3.7500 341.00 (0,0,2)
3 176x144 7.5000 430.00 (0,1,0)
4 176x144 7.5000 454.00 (0,1,1)
5 176x144 7.5000 508.00 (0,1,2)
6 176x144 15.0000 594.00 (0,2,0)
7 176x144 15.0000 631.00 (0,2,1)
8 176x144 15.0000 721.00 (0,2,2)
9 352x288 3.7500 666.00 (1,0,0)
10 352x288 3.7500 1010.00 (1,0,1)
11 352x288 7.5000 1364.00 (1,1,0)
12 352x288 7.5000 1454.00 (1,1,1)
13 352x288 15.0000 1838.00 (1,2,0)
14 352x288 15.0000 1963.00 (1,2,1)
15 352x288 30.0000 2192.00 (1,3,0)
16 352x288 30.0000 2358.00 (1,3,1)
As we can see the quality_level has different values but I could never
enconde a video that has those level modified. Could anyone please tell em
which parameters should be changed and modified to have layers with
different quality_levels, or has anyone a sample with cgs? Thanks for you
all.
And please the last question to displaya higher or lower resolution must
be user "l" and "b" and to display the layer we are watching with a lower
or higher temporal level we use "." and ";". What about quality levels? How
to switch between quality levels?
Thank you so much for your time!
Eder.

Hi, I try to use multi-thread increasing decoding performance. Also, I think if I create some threads to pick up inter frame macro blocks decoding, it will have no dependence on decoding sequence in the same frame. So I do this on BL macroblock. I modify file "Slice_data_B_svc.c" and assign function "Decode_B_BL()" to some threads. Then make sure all threads finishing their tasks before exit its' frame. But the result shows it refer wrong frames during decoding. Do I make any mistake on this or you have any suggestion? Thanks much! |

Could you point which sequence support SVC to AVC rewriting? I am far to be sure that the decoder supports it. I suppose we are able to decode an SVC layer supporting it however the decoder should not rewrite this stream compliant with AVC. I suppose this is the work of your transcoder.

Hi! First thanks for OpenSVCdec, it really helps when trying to work with H.264 SVC I was trying to take the cfgs used to encode video_5.mp4 that can be downloaded from the website. Could anyone share the the config files (main and cfg) used to encode it please? Thanks to everyone |

Hi there,
Is it possible to change spatial during decoding without sending the full
video sequence?
I have a svc video. It has a IDR frame every 32 frames.
The following is the video information.
Layer Resolution Framerate Bitrate MinBitrate DTQ
0 320x180 7.5000 72.50 72.50 (0,0,0)
1 320x180 15.0000 94.90 94.90 (0,1,0)
2 320x180 30.0000 121.10 121.10 (0,2,0)
3 640x360 7.5000 239.40 239.40 (1,0,0)
4 640x360 15.0000 312.60 312.60 (1,1,0)
5 640x360 30.0000 391.70 391.70 (1,2,0)
6 1024x576 7.5000 812.30 812.30 (2,0,0)
7 1024x576 15.0000 952.10 952.10 (2,1,0)
8 1024x576 30.0000 1118.70 1118.70 (2,2,0)
I am wondering that during decoding, if I send different video layers (by *
extractor*) to decoder, is the decoder able to handle the different spatial
automatically.
For example: initially I send the video (layer 0 to layer 8) to decoder, so
it decodes 1024X576; after 300 frames, I send the video of (layer 0 to
layer 5) to decoder, is the decoder able to decode the video in 640X360
resolution.
I have checked the Mplayer with OpenSVC library. How it changes the video
layer is that it use the interface of *void UpdateLayer(int *DqIdTable, int
*CurrDqId, int *TemporalCom, int *TemporalId, int MaxDqId, int Command) *to
change the CurrDqId. Then set the layer by SetCommandLayer*(Layer, h ->
MaxDqId, h -> CurrDqId, &h -> TemporalCom, h -> TemporalId); *But no matter
how the layer is changed, the full video sequence (NAL sequence) is sending
to decoder
*
*
The difference in my case is I am sending only the corresponding NAL
sequence to the decoder whilst changing the layer. E.g. layer 0 to layer
2 if I only want 320X180, layer 0 to layer 5 if I only want 640X360. etc.
The current solution I am doing for my case is:
Whenever meeting a IDR Access Unit, I will get the DqIdMax by GetDqIdMax(buf,
buf_size, h -> nal_length_size*, h -> DqIdTable, h -> is_avc). *Then use
this DqIdMax as the CurrDqId to decode.
For every IDR sequence, I check its DqIdMax in case the layer is changed.
So that the decoding process can be changed at least in a new IDR sequence.
I have tried my solution. It is just partly working. The case is:
- Initially I play/decode the video in layer 5 (layer 0 to layer 5), The
decoded picture is 640X360 resolution. Later I only send layer 0 to layer 2
to decoder with the new DqIdMax, the decoded picture is changed to 360X180.
[*SUCCEED*]
- Initially I decode the video in layer 8 (layer 0 to layer 5). The
decoded picture is 1024X576. Later if I only send layer 5 (layer 0 to layer
5) to decoder with the new DqIdMax, the decoded picture was not changed [
*FAILED*]. Later if I continue sending less layer (layer 0 to layer 2)
to decoder with the new DqIdMax, the decoded picture was changed to
360X180. [*Partly Succeed*]
Here is my question:
1. Is my solution right or partly right?
2. Do you guys have other solution for my case?
If there is anything in my explanation unclear, please let me know.
thank you in advance.
Jason

Fyi, the yuv reconstructed picture is of size x + 32, y +32 (with edges all around the image for motion compensation). A YUV 4:2:0 is 4 times the size less on U and V than for Y.
I will look deeper into this other bug.

Hello,
We are trying to learn how to interpret the picture that is returned by
decodeNAL(..). We have the simple code below to try to print the picture to
a .yuv file. I realize that I may need to add 32 to the width (though I'm
not sure why, the dimensions are coming as 352x288 as expected...), and I
realize that the /2 may be wrong for U and V if our assumption about format
is wrong...
But what is puzzling us is that it crashes on the loop writing the Y
component when j==1389. If we comment out the Y loop, the U loop crashes at
1388.
If anyone could give us a little insight into how to interpret the return
from decodeNAL, it would really help us.. I know I should be able to see it
from MPlayer... but the memory just gets set and passed around so much I'm
not seeing how it gets used in the end... Thank you.
