Original commit message from CVS: * gst-libs/gst/riff/riff-media.c: (gst_riff_create_video_caps_with_data), (gst_riff_create_audio_caps), (gst_riff_create_audio_template_caps): * gst-libs/gst/riff/riff-read.c: (gst_riff_peek_head): Fix for unaligned RIFF files (i.e. where all the chunks together in a LIST chunk are not of the same size as the size given in the LIST chunk header). Fixes several odd WAVE files. Also fix ADPCM (block_align property) in audio, so that wavparse based on this works now as it used to stand-alone. --- gst-libs/gst/riff/riff-media.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'gst-libs/gst/riff/riff-media.c') diff --git a/gst-libs/gst/riff/riff-media.c b/gst-libs/gst/riff/riff-media.c index 2a7529a9..c4636834 100644 --- a/gst-libs/gst/riff/riff-media.c +++ b/gst-libs/gst/riff/riff-media.c @@ -323,6 +323,7 @@ GstCaps * gst_riff_create_audio_caps (guint16 codec_id, gst_riff_strh * strh, gst_riff_strf_auds * strf, char **codec_name) { + gboolean block_align = FALSE; GstCaps *caps = NULL; switch (codec_id) { @@ -365,6 +366,15 @@ gst_riff_create_audio_caps (guint16 codec_id, "layout", G_TYPE_STRING, "microsoft", NULL); if (codec_name) *codec_name = g_strdup ("ADPCM audio"); + block_align = TRUE; + break; + + case GST_RIFF_WAVE_FORMAT_DVI_ADPCM: + caps = gst_caps_new_simple ("audio/x-adpcm", + "layout", G_TYPE_STRING, "dvi", NULL); + if (codec_name) + *codec_name = g_strdup ("DVI ADPCM audio"); + block_align = TRUE; break; case GST_RIFF_WAVE_FORMAT_MULAW: @@ -413,10 +423,16 @@ gst_riff_create_audio_caps (guint16 codec_id, gst_caps_set_simple (caps, "rate", G_TYPE_INT, strf->rate, "channels", G_TYPE_INT, strf->channels, NULL); + if (block_align) + gst_caps_set_simple (caps, + "block_align", G_TYPE_INT, strf->blockalign, NULL); } else { gst_caps_set_simple (caps, "rate", GST_TYPE_INT_RANGE, 8000, 96000, "channels", GST_TYPE_INT_RANGE, 1, 2, NULL); + if (block_align) + gst_caps_set_simple (caps, + "block_align", GST_TYPE_INT_RANGE, 1, 8192, NULL); } return caps; @@ -501,6 +517,7 @@ gst_riff_create_audio_template_caps (void) GST_RIFF_WAVE_FORMAT_ALAW, GST_RIFF_WAVE_FORMAT_MULAW, GST_RIFF_WAVE_FORMAT_ADPCM, + GST_RIFF_WAVE_FORMAT_DVI_ADPCM, /* FILL ME */ 0 }; -- cgit v1.2.1
