DecodeFrame2 returned dsNoParamSets but null about openh264

[huili2]

I cannot quite follow what you mean by "returned normally, the value is null". Could u please give more information about it?

[Icemic]

I mean, i use
pDecoder->DecodeFrame2(pBuf, nBufferSize, pData, &sDstBufInfo);

it returns dsNoParamSets, but pdata[0],pdata[1],pdata[2] is NULL
the value of each member in sDstBufInfo is 0

I dont know what happened

[huili2]

"returns dsNoParamSets" indicates no SPS or PPS is available. This surely make the decoder unable to decode the input bitstream and get what you want.
I suggest you give the SPS&PPS to decoder at the very first before any VCL packet.

Is there any problems yet? If not, I'll close it one day later.

In fact, it hasn't been solved.
I have nothing to do with the problem, but to know it cannot decode frames encoded with x264 correctly.

I cannot download your file, so unable to look into it. But from the information, it may be caused by error status of the decoder. Do you initialize the decoder with correct information, pass in all required sps/pps data? with this, I think for Baseline profile, the decoder should decode it.

[Icemic]

the file before can be downloaded at http://icemaple.info/h264/tmp.264
and the enc and dec source code is http://icemaple.info/h264/BKUCI.zip

I cannot find what is wrong

[huili2]

I checked the data, and found that the bitstream is of high profile from its SPS information. However, this open source supports only constrained baseline profile.

Thx for your help!

And, do you have plan to support high profile in future?

[huili2]

Welcome. For other profiles, till now, it is not in the short-term plan.
