v1.5.1

Encoder

• Fixed a rare race condition #580

Plugins

• Plugin is now compatible with ffmpeg 4.4 #591

v1.5.0

Encoder

• Refactored resource allocation and deallocation. With this change, all memory leaks are fixed, ffmpeg can run multi-instance encoding in parallel, total pick committed size drops. #467
• Optimized MaxNumReorderPics in vps/sps which removed unnecessary latency while decoding. #480
• Fixed corner case of sad64x64 comparison which crashed SlideShow test sequence. #500
• Fixed the encoding random hang issue with few threads. #475
• Unpack2D function multi-threading. Improved performance for non-compressed 10 bits, >= 4k input with high encMode. #460
• Fixed an encoding crash due when width < height. #462
• Output bitstream allocation at run time. Fixed output buffer too small issue. #457 #494 #523
• Fixed an encoding run to run issue when using "-lad 0" option. #455
• Refined the DEADLOCK_DEBUG output. #492
• Fixed compile warning, valgrind warning and minor errors in user guide.

Plugins

• FFmpeg: Exposed tile related parameters. #522
• GStreamer: Plugin is merged in gstreamer upstream. https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/731. GStreamer plugin in this repo will be removed once its dependencies migrate to the new GStreamer upstream release.

v1.4.3

Add this tag mainly to revert #436 which introduces regression #441 and #443 on v1.4.2.
