HandBrake has released version 1.9.1, marking the first maintenance update in the HandBrake 1.9 series, which was launched nearly two and a half months earlier. This update enhances AV1 video decoding capabilities by integrating support for the libdav1d 1.5.1 library, as well as improving support for SRT files containing overlapping subtitles. Additionally, it addresses improvements in AC3 and EAC3 extradata for MKV files.
The release fixes various bugs, including an issue with the FFV1 pixel format selection when using hardware decoders, problems caused by non-UTF-8 chapter titles, and compilation failures on AArch64 (ARM64) with GCC 14. Furthermore, there are updates for subtitle support via HarfBuzz version 10.2.0 and a revision in the libjpeg-turbo library to version 3.1.0 for better compression of preview images.
Windows users will benefit from fixes regarding the autoname function and improvements in how title progress displays during multi-instance encodes. Other rectifications target automatic naming options, crashes from chapter imports, and audio encoder visibility issues.
HandBrake 1.9 series originally rolled out on December 1, 2024, featuring significant updates such as an Intel QSV VVC hardware decoder, lossless VP9 encoding support, an ALAC audio encoder, Vorbis pass-through support, and a new option for enabling AV1 screen content coding (SCC) on Intel’s Lunar Lake QSV AV1 encoder.
