From c70a3671b059e27d75d44a76d918375ae8fde0c0 Mon Sep 17 00:00:00 2001 From: Anish Date: Sat, 4 May 2019 00:34:58 +0530 Subject: [PATCH] Fixes VideostreamGDNative crash on audio_channel=0. Added an if case to check if the mix_callback exists before running any of the audio code. Fixes: #28644 (cherry picked from commit f0757f31a44144b1d8c8a527d63f67645a4141fb) --- .../videodecoder/video_stream_gdnative.cpp | 34 ++++++++++--------- 1 file changed, 18 insertions(+), 16 deletions(-) diff --git a/modules/gdnative/videodecoder/video_stream_gdnative.cpp b/modules/gdnative/videodecoder/video_stream_gdnative.cpp index 9bb11862699..be131c54021 100644 --- a/modules/gdnative/videodecoder/video_stream_gdnative.cpp +++ b/modules/gdnative/videodecoder/video_stream_gdnative.cpp @@ -146,23 +146,25 @@ void VideoStreamPlaybackGDNative::update(float p_delta) { ERR_FAIL_COND(interface == NULL); interface->update(data_struct, p_delta); - if (pcm_write_idx >= 0) { - // Previous remains - int mixed = mix_callback(mix_udata, pcm, samples_decoded); - if (mixed == samples_decoded) { - pcm_write_idx = -1; - } else { - samples_decoded -= mixed; - pcm_write_idx += mixed; + if (mix_callback) { + if (pcm_write_idx >= 0) { + // Previous remains + int mixed = mix_callback(mix_udata, pcm, samples_decoded); + if (mixed == samples_decoded) { + pcm_write_idx = -1; + } else { + samples_decoded -= mixed; + pcm_write_idx += mixed; + } } - } - if (pcm_write_idx < 0) { - samples_decoded = interface->get_audioframe(data_struct, pcm, AUX_BUFFER_SIZE); - pcm_write_idx = mix_callback(mix_udata, pcm, samples_decoded); - if (pcm_write_idx == samples_decoded) { - pcm_write_idx = -1; - } else { - samples_decoded -= pcm_write_idx; + if (pcm_write_idx < 0) { + samples_decoded = interface->get_audioframe(data_struct, pcm, AUX_BUFFER_SIZE); + pcm_write_idx = mix_callback(mix_udata, pcm, samples_decoded); + if (pcm_write_idx == samples_decoded) { + pcm_write_idx = -1; + } else { + samples_decoded -= pcm_write_idx; + } } }
