H264 decode problem

When i am transcoding from mpeg2 to h264 everything is working fine, but when I am transcoding from H264 to H264 then I am getting some strange scenario.

Some constant frame keeps showing all the time between some other frames. I can't finalize what happens please help :)

Hi,

Are you seeing any issue using sample_multi_transcode example application?

If issue is only with your application, you can use the "mediasdk_tracer"  tool to capture a log that may help us understand what you are asking the Media SDK API to do.

Thanks

Hi Tony

 

thank you for reply.

I have build my program using libdispatcher-trace.a, but when I am xecuting it I get only

INFO:    MFXInit (impl=MFX_IMPL_HARDWARE, pVer=0.0 session=0x0x7fffe1a8f540
INFO:    invoking LoadLibrary(INFO:    MFXInit(MFX_IMPL_HARDWARE,ver=1.8,session=0x0x708020)


this two line of log. Can you tell me what is necessary to add?

Here is attached my video file. it is in mkv file I just renamed to mp4 because the upload restriction. and there is one image file which is that wrong frame showing all the time in this sample video.

So when I start transcoding transcoder will catch some frame at the beginning and in transcode process that frame is showing continuously.

Hi,

I have not seen that behavior before.

I'm just guessing, but could be issue with decode, or with frame rate conversion, or with general buffer usage.

Is the output video's framerate the same as the input?

Can you capture the *.Init parameters of Decode, VPP, and Encode ?

Thanks

The frame rate is same. It's 25. Tomorrow I will copy allvmy init commands with parameterset. Thank you.

Hi Tony,

I have resolved the problem,

I have removed MFX_BITSTREAM_COMPLETE_FRAME flag from decoder bitsream and the sequence of frames are ok.

Hi Zurab, Tony,

In relation with your issue, Recently i had also faced an issue where my output decoded frames from h264 decoder were getting corrupted. Then just by doing hit n trial mechanism i removed this flag  and issue got solved. Then i tried to back track and understand the concept of this flag. As name suggest, i think when this  flag is set, decoder expect a complete frame to be inputted for decoding. But i could not get clarity of how to identify a complete frame or that logical unit of frame which should be provided as input to decoder, specially in case of SPS and PPS. Whether it should be provided to decoder along with a complete frame, or it should be provided separately.

I have two different h264 streams and output behavior is different of both in above two cases and when this flag is set or not set.

So any input from your side??
