Struct devices::virtio::video::ffmpeg::MemoryMappingAvBufferSource

pub struct MemoryMappingAvBufferSource(MemoryMappingArena);

A simple wrapper that turns a MemoryMappingArena into an AvBufferSource.

Note: Only use this if you can reasonably assume the mapped memory won’t be written to from another thread or the VM! The reason AvBufferSource is not directly implemented on MemoryMappingArena is exactly due to this unsafety: If the guest or someone else writes to the buffer FFmpeg is currently reading from or writing to, undefined behavior might occur. This struct acts as an opt-in mechanism for this potential unsafety.
