Comment(by mythdev at telfort.nl):

 I added some debug code around the error:

 {{{
     if (!render || render->xvmc_id != AV_XVMC_ID ||
         !render->data_blocks || !render->mv_blocks ||
         (unsigned int)render->allocated_mv_blocks   > INT_MAX/(64*6) ||
         (unsigned int)render->allocated_data_blocks > INT_MAX/64     ||
         !render->p_surface) {
         av_log(avctx, AV_LOG_ERROR,
                "Render token doesn't look as expected.\n");
         av_log(avctx, AV_LOG_ERROR, "Render: %i\n", render);
         av_log(avctx, AV_LOG_ERROR, "XVMC_ID: %i == %i ??\n",
 render->xvmc_id, AV_XVMC_ID);
         av_log(avctx, AV_LOG_ERROR, "data_blocks: %i\n",
 render->data_blocks);
         av_log(avctx, AV_LOG_ERROR, "mv_blocks: %i\n", render->mv_blocks);
         av_log(avctx, AV_LOG_ERROR, "allocated_mv_blocks: %i == %i ??\n",
 render->allocated_mv_blocks, (INT_MAX/(64*6)));
         av_log(avctx, AV_LOG_ERROR, "allocated_data_blocks: %i == %i
 ??\n", render->allocated_data_blocks, (INT_MAX/64));
         av_log(avctx, AV_LOG_ERROR, "surface: %i\n", render->p_surface);
         return -1; // make sure that this is a render packet
     }
 }}}

 Resulting in the following log info (-v playback,libav)

 {{{

 }}}

 The problem seems to be that the render->data_blocks and the
 render->mv_blocks are zero.

 Does this help somehow?

 Regards.
