From 2ed3dadd6287859551fcbeaf85e09b0b3f1e8ff5 Mon Sep 17 00:00:00 2001 From: Carl Hetherington Date: Sun, 24 Sep 2023 00:34:15 +0200 Subject: Rearrange encoder threading. Soon we'll add a new encoder type, and the existing structure was already creaking a bit at the seams while handling local and remote encodes. Here we split out an encoder thread and introduce the concept of a "sync" thread (which blocks while the encoding is happening). Later we'll have another type which submits the encode request to a GPU and receives the reply back later. --- src/lib/cpu_j2k_encoder_thread.cc | 42 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 src/lib/cpu_j2k_encoder_thread.cc (limited to 'src/lib/cpu_j2k_encoder_thread.cc') diff --git a/src/lib/cpu_j2k_encoder_thread.cc b/src/lib/cpu_j2k_encoder_thread.cc new file mode 100644 index 000000000..70afac236 --- /dev/null +++ b/src/lib/cpu_j2k_encoder_thread.cc @@ -0,0 +1,42 @@ +#include "cpu_j2k_encoder_thread.h" +#include "cross.h" +#include "dcpomatic_log.h" +#include "dcp_video.h" +#include "j2k_encoder.h" +#include "scope_guard.h" +#include "util.h" + +#include "i18n.h" + + +using std::make_shared; +using std::shared_ptr; + + +CPUJ2KEncoderThread::CPUJ2KEncoderThread(J2KEncoder& encoder) + : J2KSyncEncoderThread(encoder) +{ + +} + + +void +CPUJ2KEncoderThread::log_thread_start() const +{ + start_of_thread("CPUJ2KEncoder"); + LOG_TIMING("start-encoder-thread thread=%1 server=localhost", thread_id()); +} + + +shared_ptr +CPUJ2KEncoderThread::encode(DCPVideo const& frame) +{ + try { + return make_shared(frame.encode_locally()); + } catch (std::exception& e) { + LOG_ERROR(N_("Local encode failed (%1)"), e.what()); + } + + return {}; +} + -- cgit v1.2.3
