I have tried to debug this issue to isolate the root cause but the test case is not printing any thing on the terminal and running like forever loop. test executed with strace. please find attached strace and provide your analysis.
this strace log collected for 5 mins and interrupted by CTRL+C.

this command is not responding from here.
I have pressed q did not work
I have pressed ? did not work
I have pressed CTRL+C did not work
again CRTL+C did not work.
again CRTL+C worked this time and program returned from execution.

[Naresh Kamboju (naresh-kamboju)]

same test case command works in host machine with latest ffmpeg version 1.0.1
so bug is around ffmpeg+android.

ffmpeg 1.0.1 is not functioning as expected on android and hence marking it as invalid wrt switcher project.

[Naresh Kamboju (naresh-kamboju)]

same issue has been reported again with build https://snapshots.linaro.org/android/~linaro-android-restricted/vexpress-tc2-isw-jb-gcc47-armlt-stable-open/72/

[Dave Martin (dave-martin-arm)]

Out of interest, what happens if you redirect stdin from /dev/null?

ffmpeg -i big_buck_bunny_VORBIS_2Channel_48k_128K_short.OGG -map 0 file.wav </dev/null

Dunno whether this will help, but I seem to remember having to do this in the past for some reason.
