Hi,

I try to convert serveral videos using multiple ffmpeg intances
concurrently, but it failed, only get 44 bytes result
file. Is it possible to run multiple ffmpeg intances concurrently? or,
there are some things wrong in my command as below?

<code>
ffmpeg -y -i /home/mdx/pipetest/t1.mkv \
-vcodec h263 -b 200k -r 15 -s 176x144 -aspect 11:9 \
-acodec libopencore_amrnb \
-ac 1 -ar 8000 -ab 10.2k -f 3gp 1.3gp & \
ffmpeg -y -i /home/mdx/pipetest/t2.mkv \
-vcodec h263 -b 200k -r 15 -s 176x144 -aspect 11:9 \
-acodec libopencore_amrnb \
-ac 1 -ar 8000 -ab 10.2k -f 3gp 2.3gp & \
ffmpeg -y -i /home/mdx/pipetest/t3.mkv \
-vcodec h263 -b 200k -r 15 -s 176x144 -aspect 11:9 \
-acodec libopencore_amrnb \
-ac 1 -ar 8000 -ab 10.2k -f 3gp 3.3gp &
</code>
