From e54e30c88940fc090409cc60df4e452af6ef178d Mon Sep 17 00:00:00 2001 From: Nicolas George Date: Tue, 14 Aug 2012 18:35:50 +0200 Subject: lavfi: grant all permissions on mallocated audio buffers. The permissions not requested by the filter that created the buffer may be useful for a later filter and avoid a copy. --- libavfilter/audio.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'libavfilter/audio.c') diff --git a/libavfilter/audio.c b/libavfilter/audio.c index aa87488f5f..525b471065 100644 --- a/libavfilter/audio.c +++ b/libavfilter/audio.c @@ -42,6 +42,10 @@ AVFilterBufferRef *ff_default_get_audio_buffer(AVFilterLink *link, int perms, int nb_channels = av_get_channel_layout_nb_channels(link->channel_layout); int planes = planar ? nb_channels : 1; int linesize; + int full_perms = AV_PERM_READ | AV_PERM_WRITE | AV_PERM_PRESERVE | + AV_PERM_REUSE | AV_PERM_REUSE2 | AV_PERM_ALIGN; + + av_assert1(!(perms & ~(full_perms | AV_PERM_NEG_LINESIZES))); if (!(data = av_mallocz(sizeof(*data) * planes))) goto fail; @@ -49,7 +53,7 @@ AVFilterBufferRef *ff_default_get_audio_buffer(AVFilterLink *link, int perms, if (av_samples_alloc(data, &linesize, nb_channels, nb_samples, link->format, 0) < 0) goto fail; - samplesref = avfilter_get_audio_buffer_ref_from_arrays(data, linesize, perms, + samplesref = avfilter_get_audio_buffer_ref_from_arrays(data, linesize, full_perms, nb_samples, link->format, link->channel_layout); if (!samplesref) -- cgit v1.2.3
