MediaSDK sample transcode app input file for running 5 parallel MPEG2->AVC
transcoding streams
After removing the above test-case from regular testing, there's another one
that hangs, a bit simpler one. As the earlier test-case can trigger deadlock
alone, I'm assuming this one can also.
1. Build media-driver & MediaSDK:

2. Run 5 instances of following multi-stream process in parallel in a same
process group, with the attached parameter file & suitably sized MPEG2 input
file:
sample_multi_transcode -par parameters.txt
3. Kill the process group before above command finishes
4. Repeat from 2)</pre>
