[Libav-user] Does ffmpeg supports multiple output files?

[mahesh p]

Hi,

     encoder itself produces different video output files.
for ex: bitstream_1.out, bitstream_2.out, bitstream_3.out


ffmpeg -i input -filter_complex \
"[0:v]split=2[s0][s1]; \
 [s0]scale=1280:-2[v0]; \
 [s1]scale=640:-2[v1]" \
-map "[v0]" -map "[v1]" -map 0:a -c:v libx264 -c:a aac -f tee \
"[select=\'v:0,a\']local0.mkv| \
 [select=\'v:0,a\':f=flv]rtmp://server0/app/instance/playpath| \
 [select=\'v:1,a\']local1.mkv| \
 [select=\'v:1,a\':f=flv]rtmp://server1/app/instance/playpath"


but In above ffmpeg example two x264 encoder instances will run in parallel
right? If one libx264 encoder produces different video output files how
ffmpeg will handle?
