I play video(mpg) no sound with mplayer?

I use this command :mplayer -ao v4l2 005.mpg

Hi Evan,

Are you able to play any audio file on your board (aplay command) ?

Dear Titus,

     I can aplay audio with wav format(such as aplay test.wav), and I can play audio with mpg123, but mplayer have no sound.

Thanks.

Hi Evan,

Have you tried to play audio file with mplayer ?

mplayer test.wav

mplayer 005.mpg

Please attach the both o/p logs generated from mplayer.

mplayer test.wav logs as below:

[  161.703802] write 3 = 1932 ..............

such as this information is printf information in kernel, you can ignore.

MPlayer interrupted by signal 11 in module: check_framedrop
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.

Hi Titus,

    Are you on line?

Hi Evan,

I'm able to play test.wav ,mp3 and video files with out any kernel panics on my armv7 platform (keystone)

Could you please give your email ID, I will mail the mplayer binary to you.

I think the issue is due to toolchain (bug)

Which toolchain are your using ?

from TI SDK or open source ?

Hi Titus,

   I use toolchain from TI SDK(ti-sdk-am335x-evm-06.00.00.00-Linux-x86-Install).

   My email ID is : lanniao22@126.com  , you can send binary to the email.

Thanks.

Hi Titus,

     Please give me play command with mplayer on the same time(such as mplayer 005.mpg).

Thanks.
