My compile of mplayer did not have mpg123 codec. So it uses ffmp2float decoder for mp3.
In 486 PC i downloaded mpg123-1.22.4.tar.bz2
Replaced write_alsa function in alsa.c with this one:
static int write_alsa(audio_output_t *ao, unsigned char *buf, int bytes)This is present in mpg123-1.14.4 and changed in later versions. If above change is not made then it will not play mp3 files and cpu usage is 100%.
{
snd_pcm_t *pcm=(snd_pcm_t*)ao->userptr;
snd_pcm_uframes_t frames;
snd_pcm_sframes_t written;
frames = snd_pcm_bytes_to_frames(pcm, bytes);
written = snd_pcm_writei(pcm, buf, frames);
if (written == -EINTR) /* interrupted system call */
written = 0;
else if (written == -EPIPE) { /* underrun */
if (snd_pcm_prepare(pcm) >= 0)
written = snd_pcm_writei(pcm, buf, frames);
}
if (written >= 0)
return snd_pcm_frames_to_bytes(pcm, written);
else
{
if(snd_pcm_state(pcm) == SND_PCM_STATE_SUSPENDED)
{
/* Iamnothappyabouthisnothappyreallynot. */
snd_pcm_resume(pcm);
if(snd_pcm_state(pcm) == SND_PCM_STATE_SUSPENDED)
{
error("device still suspended after resume hackery... giving up");
return -1;
}
}
return 0;
}
}
Patch file for download.
Then created package.
Configuration line was:
./configure --prefix=/usr i486-kola-linux --enable-int-quality=yes --enable-buffer=yes --enable-modules=no --with-optimization=3Installed it on 486 and also on my virtual box so i can compile mplayer 1.1.1
After transferring new mplayer binary to 486 made test. Player command line options: -lavdopts lowres=0:skiploopfilter=all:skipidct=bidir -framedrop -af channels 1
