After 1 or 2 hours of encoding, FFMPEG stops suddenly. The error is occuring even if I write to a file. I tried with fifo_size and buffer_size options. But, no change in the error. Below is the FFMPEG command I am using: ffmpeg -y -i udp://@224.2.4.5:9900 -acodec libfaac -ac 2 -ab 64k -vcodec libx264 -f mpegts -threads 0 -async 2 -b:v 1200k udp://224.2.9.4:9900 2> logout.txt Below is the truncated console output. Please find the attached log to see the complete console output. {{{ ffmpeg version git-2012-05-12-70e9308 Copyright (c) 2000-2012 the FFmpeg developers built on May 12 2012 17:58:29 with gcc 4.6.1 configuration: --enable-gpl --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-nonfree --enable-version3 --enable-x11grab libavutil 51. 50.100 / 51. 50.100 libavcodec 54. 21.101 / 54. 21.101 libavformat 54. 4.100 / 54. 4.100 libavdevice 53. 4.100 / 53. 4.100 libavfilter 2. 72.105 / 2. 72.105 libswscale 2. 1.100 / 2. 1.100 libswresample 0. 11.100 / 0. 11.100 libpostproc 52. 0.100 / 52. 0.100 [mpegts @ 0x15a6120] Unable to seek back to the start [mp3 @ 0x15d6d60] Header missing [h264 @ 0x15d09e0] non-existing SPS 0 referenced in buffering period Last message repeated 1 times [h264 @ 0x15d09e0] non-existing PPS referenced [h264 @ 0x15d09e0] non-existing SPS 0 referenced in buffering period [h264 @ 0x15d09e0] non-existing PPS 0 referenced [h264 @ 0x15d09e0] decode_slice_header error [h264 @ 0x15d09e0] no frame!
