For the ImgU output buffers this is not\nrequired, as failed buffes should be anyhow delivered to applications in\norder to report their failure.\n\nSigned-off-by: Jacopo Mondi <jacopo@jmondi.org>\n---\n src/libcamera/pipeline/ipu3/ipu3.cpp | 6 ++++++\n 1 file changed, 6 insertions(+)", "diff": "diff --git a/src/libcamera/pipeline/ipu3/ipu3.cpp b/src/libcamera/pipeline/ipu3/ipu3.cpp\nindex 5204487684c2..11bf3af66ae6 100644\n--- a/src/libcamera/pipeline/ipu3/ipu3.cpp\n+++ b/src/libcamera/pipeline/ipu3/ipu3.cpp\n@@ -916,6 +916,9 @@ int PipelineHandlerIPU3::registerCameras()\n */\n void IPU3CameraData::imguInputBufferReady(Buffer *buffer)\n {\n+\tif (buffer->status() != Buffer::BufferSuccess)\n+\t\treturn;\n+\n \tcio2_.output_->queueBuffer(buffer);\n }\n \n@@ -946,6 +949,9 @@ void IPU3CameraData::imguOutputBufferReady(Buffer *buffer)\n */\n void IPU3CameraData::cio2BufferReady(Buffer *buffer)\n {\n+\tif (buffer->status() != Buffer::BufferSuccess)\n+\t\treturn;\n+\n \timgu_->input_->queueBuffer(buffer);\n }\n \n", "prefixes": [ "libcamera-devel", "2/3" ] }
