v6.7.7.1.1

What's Changed

Only one very small change, but it's an important change to modular builds: all failed loads now correctly propagate exceptions or promise rejections. Previously, some cases were silently dropped.

Full Changelog: v6.6.7.1.1...v6.7.7.1.1

6.6.7.1.1

What's Changed

• Support for recent emsdks (≥4, ≥4.0.7)
• Support for modular builds, which exclude extraneous libraries and provide exactly enough to demux or decode one codec
• Fix adts fragment incorrect file name, and also support emsdk 4.0.7 by @Jamie0 in #81

New Contributors

• @Jamie0 made their first contribution in #81

Full Changelog: v6.5.7.1...v6.6.7.1.1

6.5.7.1

Changes

• Added avcodec_flush_buffers
• Added accessors to unify the various ways of encoding channels and channel layouts.
• Created a types-only package, @libav.js/types, which should be much smaller than the full variants and will cut down on multi-variant madness.
• Corrected timebase calculation in ff_filter_multi.
• Corrected several typos that broke or diminished features in unusual loading modes.

6.4.7.1

What's Changed

• Fixed bugs in seeking test
• expose av_seek_frame by @stepancar in #68
• Made mkreaderdev create a fresh buffer, so that any previous EOF doesn't persist.
• Fixes around TypeScript + ES6 + default export nonsense that should make libav.js import better in Node.
• Added duration and start_time to AVFormatContext exports.
• Change BigInteger to BigInt by @longnguyen2004 in #69

New Contributors

• @stepancar made their first contribution in #68

Full Changelog: v6.3.7.1...v6.4.7.1

6.3.7.1

What's Changed

• Fixed files in the CLI in the threaded version. Files never worked from a thread, but the CLI used to do the actual file access in the main thread. Now it does again (by just not using threads, even in the threaded version; the threads will come from the codecs and filters, not the frontend).
• Fixed some similar threading issues that were breaking certain tests in the threaded build.
• Can now build with emsdk ≥ 3.1.65. Previously versions after 3.1.50 were blocked due to a bug that caused libvpx to generate incorrect code. emsdk has evidently fixed that.
• Throw exceptions on OOM writes. libav's code is not very resilient against running out of memory while writing to a file, and if that happens, it has strange effects. Rather than trying to make the existing code more resilient, I just used JavaScript-level exceptions to break out in that case.
• A few header changes, mainly exposing the emsdk version (now that it's unfixed).
• Fix broken type exports by @longnguyen2004 in #65

New Contributors

• @longnguyen2004 made their first contribution in #65

Full Changelog: v6.2.7.1...v6.3.7.1

6.2.7.1

Note: The flurry of releases recently (after 6.0.7.0.1, which was pretty major) are all just fixing bugs in a feature which I believe to be rarely used, the non-copyout copyout functions (copying out as pointers), and more specifically its interaction with timebases. I'm working on a separate tool that uses this feature and finding that I never got its interaction with timebases right, so I'm fixing it now.

Changes:

• When writing to a muxer using packets copied out as pointers, timebases are preserved correctly.
• When reading from a filter using packets copied out as pointers, timebases are preserved correctly.

Full Changelog: v6.1.7.1...v6.2.7.1

6.1.7.1

Changes:

• Finally added onread, so that streaming reader devices can use largely the same API as block reader devices. This replaces and deprecates ff_reader_dev_waiting.
• Added float32 to wav builds. It's particularly useful on the web, where all web audio interfaces use floats, and costs nothing.
• Bumped FFmpeg version to 7.1.
• Work on making time bases more consistent, particularly when using non-copying "ptr" modes. This should make it easier to keep times consistent through chains of steps.
• Added the time_base option to ff_init_decoder
• Fixed some TypeScript issues.

Full Changelog: v6.0.7.0.2...v6.1.7.1

6.0.7.0.2

What's Changed

• Updated to FFmpeg 7.
• Reimplemented the CLI support (ffmpeg() and ffprobe() functions) to use the modern (threaded) version, even on non-threaded platforms, by implementing pseudo-threads with emfiberthreads.
• Added support for writing to FileSystemFileHandles.
• fixes for threaded libav.js when building with newer emsdk by @dumbmoron in #60
• Add missing type for unlinkreadaheadfile() function by @wukko in #61
• explictly define type for each export by @aidenlx in #64
• Compatibility fixes with newer and older emsdk versions.
• Added a JavaScript CodecParameters type, for copying codecpars at the JS level.
• Updated/corrected some dependency licensing information.
• Switched minifier to terser.
