From 95b8ca0cda7e34b9e9c1f033f176ab24f4d5ba34 Mon Sep 17 00:00:00 2001 From: Sreerenj Balachandran Date: Fri, 7 Aug 2015 08:43:44 +0300 Subject: [PATCH] decoder: hevc: Workaround to recognize wrongly encoded main profile streams HACK: This is a work-around to identify some main profile streams having wrong profile_idc. There are some wrongly encoded main profile streams(eg: ENTP_C_LG_3.bin) which doesn't have any of the profile_idc values mentioned in Annex-A, instead general_profile_idc has been set as zero and having general_profile_compatibility_flag[general_profile_idc] is TRUE. Assuming them as MAIN profile for now. https://bugzilla.gnome.org/show_bug.cgi?id=753226 Signed-off-by: Sreerenj Balachandran --- gst-libs/gst/vaapi/gstvaapidecoder_h265.c | 20 +++++++++++++++++--- 1 file changed, 17 insertions(+), 3 deletions(-) diff --git a/gst-libs/gst/vaapi/gstvaapidecoder_h265.c b/gst-libs/gst/vaapi/gstvaapidecoder_h265.c index 50a0125..3ab7445 100644 --- a/gst-libs/gst/vaapi/gstvaapidecoder_h265.c +++ b/gst-libs/gst/vaapi/gstvaapidecoder_h265.c @@ -608,7 +608,8 @@ get_max_dec_frame_buffering (GstH265SPS * sps) /* Fixme: Add limit check based on Annex A */ /* Assuming HighestTid as sps_max_sub_layers_minus1 */ - return MAX (1, (sps->max_dec_pic_buffering_minus1[sps->max_sub_layers_minus1] + 1)); + return MAX (1, + (sps->max_dec_pic_buffering_minus1[sps->max_sub_layers_minus1] + 1)); } static void @@ -1022,8 +1023,21 @@ get_profile (GstVaapiDecoderH265 * decoder, GstH265SPS * sps, guint dpb_size) profile = gst_vaapi_utils_h265_get_profile (sps->profile_tier_level.profile_idc); - if (!profile) - return GST_VAAPI_PROFILE_UNKNOWN; + if (!profile) { + /* HACK: This is a work-around to identify some main profile streams having wrong profile_idc. + * There are some wrongly encoded main profile streams(eg: ENTP_C_LG_3.bin) which doesn't + * have any of the profile_idc values mentioned in Annex-A, instead general_profile_idc + * has been set as zero and having general_profile_compatibility_flag[general_profile_idc] + * is TRUE.
