Actually, I'm seeing weirdness in output now after using this flag.
Here's the full command....am I doing this right? I want to generate a poster
every 60 seconds in addition to copy a stream.
ffmpeg \
-y \
-threads 8 \
-analyzeduration 10 \
-probesize 10000000 \
-user-agent "${agent}" \
-headers "User-Agent: ${agent}" \
-headers "Connection: keep-alive" \
-cookies "${cookie} path=/; domain=${cookie_host};\n${cookie2} path=/;
domain=${cookie_host};\n" \
-i "${input}" \
-copytb 1 \
-vf fps=1/60 -update 1 "${path}/poster.png" \
-hls_time 10 -hls_list_size 10 -hls_wrap 10 \
-hls_flags delete_segments \
-hls_segment_filename "${path}/video%03d.ts" \
-c:v copy -c:a copy \
"${out_m3u8}"

well, that was missing in your initial post
http://www.catb.org/esr/faqs/smart-questions.html#beprecise helps a lot
because it saves answers "try this and that" when you already tried
"this and that"
