unfortunately the release I’ve done only four days ago contains a nasty bug in the HEVC/H.265 code, and people are hitting it in droves. Therefore I’m releasing a fix for that today
You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.
Here are the NEWS since the previous release:
New features and enhancements
- mkvmerge: AAC: added support for LOAS/LATM files with channel configuration indexes 9–21 (e.g. channel count 22.2 for index 13) according to Rec. ITU-R BS.1196-7 & ISO/IEC 23008-3:2019. Fixes #3081.
- mkvmerge: HEVC/H.265 parser: fixed invalid memory access that could happen when reading certain types of HEVC data (e.g. with changing parameter sets mid-stream) from certain containers (e.g. Matroska). This bug was introduced in release 56.0.0. Fixes #3083.
- mkvextract: AAC: mkvextract will now abort with an useful error message when the user tries to extract a track whose ‘audio-specific config’ element in
CodecPrivatesignals a number of channels of 7 or greater than 8 as that isn’t supported by the ADTS format.
Build system changes
- configure: the
--enable-ubsanoption hasn’t actually enabled anything since release 39.0.0.
Have fun 😎
