From 89ed1748ae84742ccf37118b080f440988318af2 Mon Sep 17 00:00:00 2001 From: joyping Date: Tue, 20 Aug 2002 14:15:25 +0000 Subject: changed spdif default from "hw:0,2" to general alias "iec958" based on a patch by Benedikt Hunz corrected typo in ugly spdif-warning message added 32/20bit modes for 'high-end'-soundcards disabled hw-mixer-access for big-endian machines (mplayer seems to screw up hw-mixer on LinuxPPC running ALSA needs more testing, but its safer to disable it for now.) git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@7051 b3059339-0415-0410-9bf9-f77b7e298cf2 --- libao2/ao_alsa1x.c | 111 ++++++++++++++++++++++++++++++----------------------- 1 file changed, 63 insertions(+), 48 deletions(-) (limited to 'libao2/ao_alsa1x.c') diff --git a/libao2/ao_alsa1x.c b/libao2/ao_alsa1x.c index 6260827554..e121514aea 100644 --- a/libao2/ao_alsa1x.c +++ b/libao2/ao_alsa1x.c @@ -140,17 +140,9 @@ snd_pcm_t *spdif_init(char *pcm_name) } if ((err = snd_ctl_elem_write(ctl_handler, ctl)) < 0) { //fprintf(stderr, "Unable to update the IEC958 control: %s\n", snd_strerror(err)); - printf("alsa-spdif-init: cant set spdif-trough automatically\n"); + printf("alsa-spdif-init: cant set spdif-through automatically\n"); goto __diga_end; } - //test area - /* elem_device = snd_ctl_elem_id_get_device(elem_id); */ - /* elem_name = snd_ctl_elem_value_get_name(ctl); */ - /* snd_ctl_elem_value_get_iec958(ctl, &spdif); */ - /* printf("spdif = %i, device = %i\n", &spdif, elem_device); */ - /* printf("name = %s\n", elem_name); */ - //end test area - snd_ctl_close(ctl_handler); __diga_end: @@ -211,6 +203,8 @@ static int control(int cmd, int arg) return CONTROL_TRUE; case AOCONTROL_GET_VOLUME: case AOCONTROL_SET_VOLUME: +#ifndef WORDS_BIGENDIAN +{ //seems to be a problem on macs? { ao_control_vol_t *vol = (ao_control_vol_t *)arg; @@ -303,7 +297,17 @@ static int control(int cmd, int arg) snd_mixer_close(handle); return CONTROL_OK; } +}// end big-endian +#endif +#ifdef WORDS_BIGENDIAN +{ + { + return (CONTROL_UNKNOWN); } +} +#endif + + } //end witch return(CONTROL_UNKNOWN); } @@ -344,49 +348,60 @@ static int init(int rate_hz, int channels, int format, int flags) //ao_data.buffersize = MAX_OUTBURST; // was 16384 switch (format) - { - case AFMT_S8: - alsa_format = SND_PCM_FORMAT_S8; - break; - case AFMT_U8: - alsa_format = SND_PCM_FORMAT_U8; - break; - case AFMT_U16_LE: - alsa_format = SND_PCM_FORMAT_U16_LE; - break; - case AFMT_U16_BE: - alsa_format = SND_PCM_FORMAT_U16_BE; - break; + { + case AFMT_S8: + alsa_format = SND_PCM_FORMAT_S8; + break; + case AFMT_U8: + alsa_format = SND_PCM_FORMAT_U8; + break; + case AFMT_U16_LE: + alsa_format = SND_PCM_FORMAT_U16_LE; + break; + case AFMT_U16_BE: + alsa_format = SND_PCM_FORMAT_U16_BE; + break; #ifndef WORDS_BIGENDIAN - case AFMT_AC3: + case AFMT_AC3: #endif - case AFMT_S16_LE: - alsa_format = SND_PCM_FORMAT_S16_LE; - break; + case AFMT_S16_LE: + alsa_format = SND_PCM_FORMAT_S16_LE; + break; #ifdef WORDS_BIGENDIAN - case AFMT_AC3: + case AFMT_AC3: #endif - case AFMT_S16_BE: - alsa_format = SND_PCM_FORMAT_S16_BE; - break; - default: - alsa_format = SND_PCM_FORMAT_MPEG; - break; - } + case AFMT_S16_BE: + alsa_format = SND_PCM_FORMAT_S16_BE; + break; + case AFMT_S32_LE: + alsa_format = SND_PCM_FORMAT_S32_LE; + break; + case AFMT_S32_BE: + alsa_format = SND_PCM_FORMAT_S32_BE; + break; + + default: + alsa_format = SND_PCM_FORMAT_MPEG; + break; + } switch(alsa_format) - { - case SND_PCM_FORMAT_S16_LE: - case SND_PCM_FORMAT_U16_LE: - ao_data.bps *= 2; - break; - case -1: - printf("alsa-init: invalid format (%s) requested - output disabled\n", - audio_out_format_name(format)); - return(0); - default: - break; - } + { + case SND_PCM_FORMAT_S16_LE: + case SND_PCM_FORMAT_U16_LE: + ao_data.bps *= 2; + break; + case SND_PCM_FORMAT_S32_LE: + case SND_PCM_FORMAT_S32_BE: + ao_data.bps *= 4; + break; + case -1: + printf("alsa-init: invalid format (%s) requested - output disabled\n", + audio_out_format_name(format)); + return(0); + default: + break; + } if (ao_subdevice) { //start parsing ao_subdevice, ugly and not thread safe! @@ -498,7 +513,7 @@ static int init(int rate_hz, int channels, int format, int flags) if (device_set) alsa_handler = spdif_init(alsa_device); else - alsa_handler = spdif_init("hw:0,2"); + alsa_handler = spdif_init("iec958"); } //setting modes for block or nonblock-mode @@ -512,7 +527,7 @@ static int init(int rate_hz, int channels, int format, int flags) set_block_mode = 0; str_block_mode = "block-mode"; } - //cvs cosmetics fix + //sets buff/chunksize if its set manually if (ao_data.buffersize) { switch (ao_data.buffersize) -- cgit v1.2.3
