I am dealing with a ts file, following is ffprobe output: ffprobe version N-45589-gb6a0b8b- http://johnvansickle.com/ffmpeg/ Copyright (c) 2007-2014 the FFmpeg developers built on Aug 28 2014 02:30:32 with gcc 4.8 (Debian 4.8.3-9) configuration: --enable-gpl --enable-version3 --disable-shared --disable-debug --enable-runtime-cpudetect --enable-libmp3lame --enable-libx264 --enable-libx265 --enable-libwebp --enable-libspeex --enable-libvorbis --enable-libvpx --enable-libfreetype --enable-fontconfig --enable-libxvid --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-gray --enable-libopenjpeg --enable-libopus --disable-ffserver --enable-libass --enable-gnutls --cc=gcc-4.8 libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 0.101 / 56. 0.101 libavformat 56. 3.100 / 56. 3.100 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 0.103 / 5. 0.103 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 [hevc @ 0x298b4a0] No start code is found.

The problem I'm having is that seeking on this file is extremely slow, it took more than 1 minute to complete seek operation. This ts file is 500MB in size, has 2,793,052 ts packets, 2750469 video packets, 137 video packets with random_acces_indicator. What's the possible reason for the slow seek? Why is ffmpeg reporting these errors? What do I need to do for the analysis? _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
