[Libav-user] Memory Leaks?

[Harald Schlangmann]

I’m unreferencing it when a frame has been completely read:

>>                int     frameFinished;
>> 
>>                ret = avcodec_decode_video2 (videoSource->pVideoCodecCtx, videoSource->pVideoFrameRaw, &frameFinished, &packet);
>> 
>>                if (ret>=0)
>>                {
>>                    if (frameFinished)
>>                    {
>> 			…
>> 
>>                        av_frame_unref (videoSource->pVideoFrameRaw); 

Unreferencing it before the avcodec_decode_video2 is most probably wrong (at least in the theoretical case the frame comes in more than 1 package)?

Greetings Harald
