ffmpeg error while segmenting
- by Tommy Ng
I'm using ffmpeg and segmenter on Ubuntu 10.04 to create the transport stream from flv/h264 video files and then segment the ts segments for ipad streaming.
Some ts files show an error with segmenter -
Output #0, mpegts, to '29':
Stream #0.0: Video: 0x0000, yuv420p, 480x360, q=2-31, 90k tbn, 25
tbc
Stream #0.1: Audio: 0x0000, 0 channels, s16
[mpegts @ 0x11f4ac0]sample rate not set
Could not write mpegts header to first
output file
my ffmpeg command for creating the ts file -
ffmpeg -i 1.flv -f mpegts -acodec
libfaac -ar 48000 -ab 64k -s 480x360
