If the output format cannot be written, `cam' reports an\nerror and doesn't write anything.\n\nThis is all right with a single stream input but impractical with\nmultiple streams of different output formats (e.g. a processed stream +\na raw stream) where some of them can be written in the supported format\nwhile the other not. In such a case, it's better to write the supported\nformats as PPM files and the unsupported formats as raw files, with the\ncorresponding warning on stderr. `.raw' extension is added to the file\nname in such a case to make clear it's not a PPM file.\n\nThis is a sort of hack but serves the purpose for the moment.\n\nSigned-off-by: Milan Zamazal <mzamazal@redhat.com>\n---\n src/apps/cam/file_sink.cpp | 16 +++++++++++-----\n 1 file changed, 11 insertions(+), 5 deletions(-)", "diff": "diff --git a/src/apps/cam/file_sink.cpp b/src/apps/cam/file_sink.cpp\nindex 76e21db9..1a866137 100644\n--- a/src/apps/cam/file_sink.cpp\n+++ b/src/apps/cam/file_sink.cpp\n@@ -7,6 +7,7 @@\n \n #include <array>\n #include <assert.h>\n+#include <errno.h>\n #include <fcntl.h>\n #include <iomanip>\n #include <iostream>\n@@ -133,11 +134,16 @@ void FileSink::writeBuffer(const Stream *stream, FrameBuffer *buffer,\n \tif (fileType_ == FileType::Ppm) {\n \t\tret = PPMWriter::write(filename.c_str(), stream->configuration(),\n \t\t\t\t image->data(0));\n-\t\tif (ret < 0)\n-\t\t\tstd::cerr << \"failed to write PPM file `\" << filename\n-\t\t\t\t << \"'\" << std::endl;\n-\n-\t\treturn;\n+\t\tif (ret == -EINVAL) {\n+\t\t\tfilename += \".raw\";\n+\t\t\tstd::cerr << \"cannot write file in PPM format, writing `\"\n+\t\t\t\t << filename << \"' instead\" << std::endl;\n+\t\t} else {\n+\t\t\tif (ret < 0)\n+\t\t\t\tstd::cerr << \"failed to write PPM file `\" << filename\n+\t\t\t\t\t << \"'\" << std::endl;\n+\t\t\treturn;\n+\t\t}\n \t}\n \n \tfd = open(filename.c_str(), O_CREAT | O_WRONLY |\n", "prefixes": [ "RFC", "v2", "13/13" ] }
