What for a strange code below? How it is possible to compare the (pkt->dts) to the (avist->)packet_count? {{{ avi_write_packet() while(enc->block_align==0 && \ pkt->dts != AV_NOPTS_VALUE && \ pkt->dts > avist->packet_count && \ enc->codec_id != AV_CODEC_ID_XSUB){ AVPacket empty_packet; if( pkt->dts - avist->packet_count > 60000){ }}} How to reproduce: Apply avienc_show_emtied.diff patch (see attachment). {{{ % ./ffmpeg
