How to do Apple HLS using Avconv
mkdir /var/www/hls
ln -s /run/shm /var/www/hls
RUN This command
avconv -re -i 'rtmp://RED_5_IP/live/stream_name' -bsf h264_mp4toannexb -vcodec libx264 -acodec libfaac -b:v 448k -b:a 40k -ar 22050 -s 640x360 -hls_time 10 -hls_list_size 4 /var/www/hls/output_a_.m3u8
but when i ran last part, my streaming didn't start and I've get this error:
avconv: relocation error: /usr/local/lib/libavfilter.so.3: symbol sws_isSupportedEndiannessConversion, version LIBSWSCALE_2 not defined in file libswscale.so.2 with link time reference
what i should to do?
Thanks.

Answer 1

The problem is that avconv is unable to load the correct libav libraries. Probably the issue is that /usr/local/lib is not in your linker path. You can add it to the /etc/ld.so.conf file and then run ldconfig.
Another solution is to compile libav statically.
That can be done by changing this
./configure --disable-debug --enable-librtmp --enable-libmp3lame
--enable-libfaac --enable-nonfree --enable-libx264 --enable-gpl --enable-version3 --enable-shared
to this
./configure --disable-debug --enable-librtmp --enable-libmp3lame
--enable-libfaac --enable-nonfree --enable-libx264 --enable-gpl --enable-version3 --enable-static
