Hence when\nDebayer::process(); runs it must run in the same thread as\nDebayer::configure() or the hidden Gegl context handles will not point\nto the same place.\n\nMove start thread into configure() as a first step towards this.\n\nCo-developed-by: Robert Mader <robert.mader@collabora.com>\nSigned-off-by: Robert Mader <robert.mader@collabora.com>\nSigned-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org>\n---\n src/libcamera/software_isp/software_isp.cpp | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)", "diff": "diff --git a/src/libcamera/software_isp/software_isp.cpp b/src/libcamera/software_isp/software_isp.cpp\nindex 928a2520c..afa4eb7a8 100644\n--- a/src/libcamera/software_isp/software_isp.cpp\n+++ b/src/libcamera/software_isp/software_isp.cpp\n@@ -265,6 +265,8 @@ int SoftwareIsp::configure(const StreamConfiguration &inputCfg,\n \tif (ret < 0)\n \t\treturn ret;\n \n+\tispWorkerThread_.start();\n+\n \treturn debayer_->configure(inputCfg, outputCfgs, ccmEnabled_);\n }\n \n@@ -346,7 +348,6 @@ int SoftwareIsp::start()\n \tif (ret)\n \t\treturn ret;\n \n-\tispWorkerThread_.start();\n \treturn 0;\n }\n \n", "prefixes": [ "v2", "15/22" ] }
