Answering to myself, in my previous attempt, the second hls output expects
a separate set of transcode process, hence the unable to map stream error.
The better solution would be to use tee to send to multiple outputs,
however the latest git seems to be suffering from this
Slight different command line, i'm trying to produce 2 separate abr streams
with different stream map structures, as well as doing transcoding but that
should not be of any circumstance:
./ffmpeg -ignore_unknown -async 1 -probesize 1M -analyzeduration 100 \
-i

i tried for live, it took *only the first* var_stream_map...
ffmpeg -v verbose -y -vstats_file stats.txt -re -i 'http://URL.m3u8'
-map 0:v:1 -c:v copy -copyts -start_at_zero -metadata:s:0 language=eng
-map 0:v:2 -c:v copy -copyts -start_at_zero -metadata:s:0 language=eng
-map 0:v:3 -c:v copy
Hi to everybody,
Is it possible to have multiple HLS outputs specified with
different var_stream_map structures ?
Thanks,
Viorel

Using eq() on floating points is indeed a bad idea because of floating

In the code of the select filter I've found:
#define TS2D(ts) ((ts) == AV_NOPTS_VALUE ? NAN : (double)(ts))
select->var_values[VAR_T ] = TS2D(frame->pts) *

The expression parser is very limited and hard to extend. Furthermore,
its API is very inconvenient. If somebody were to rewrite it from
scratch, it would be a great progress. (But do not

If you want support on this mailing list, do not use -v warning
and post the command line together with the complete, uncut
