Problems with the H.264-encoder

[mathiasjohanson]

Hi,

I am currently trying to get the H.264-encoder to work. The compilation went fine but the problem occurs with the encoded movie. I use an yuv-file which has successfully been used with the MPEG2-encoder where I have tried to match the .par file for the H.264-encoder. Below is the .par-file used for the MPEG2-encoder and then the .par-file I have used for the H.264-encoder. I have no idea what is going wrong, can someone please help me.

Thanks in advance

Hi,

it is a bit unclear what the problem you have.I have to say that there is some assimetry between our H.264 encoder and H.264 decoder samples. Our H.264 encoder do support JM7.3 while our H.264 decoder supports only JM6.1. Sorry for that inconvenience. You should contact with technical support, probably they can provide you update for this sample.

Regards,

Vladimir

We make some updated on H.264 coding samples, please try download video samples again to get the updated samples for H.264.
