    Dmitry,

    Can you share the stream that you have generated using the TI encoder? It could happen that the VLC does not support some feature that is being used by the TI encoder.Have you tried playing the encoded stream using a H264 Stream analyzer?

    Regards,

    Dmitry,

    These streams definitely have some problems. I think that the encoder is not being passed the correct parameters. Can you share the Create time parameters and dynamic params that you are using to set up the encoder?

    Regards,
