## Video codecs
Every iOS build includes VideoToolbox, OpenH264, dav1d, and SVT-AV1. H.264 uses
VideoToolbox by default; choose software processing under **设置 → 视频编解码 →
处理方式** (Settings → Video codec → Processing mode) to use OpenH264 for H.264.
The change takes effect on the next connection. AV1 encoding uses SVT-AV1 and AV1 decoding
uses dav1d; VideoToolbox AV1 hardware decoding is currently unsupported.
Every iOS build includes VideoToolbox, dav1d, and SVT-AV1. H.264 uses
VideoToolbox exclusively; OpenH264 is excluded from the iOS dependencies and
native archive. The hardware/software processing setting has been removed,
and preferences saved by older versions are no longer read. H.264 codec
initialization failure is reported without a software fallback.
AV1 encoding uses SVT-AV1 and AV1 decoding uses dav1d; VideoToolbox AV1 hardware
decoding is currently unsupported. Desktop builds retain OpenH264.
The native build script checks the merged archive for OpenH264 entry points
and rejects a build if they are present, including in cached archives.
The unused libaom backends are excluded by default. To include them for development,
set the `MINIRTC_ENABLE_AOM` environment variable (or Xcode user-defined build setting)
