brotlidecompress

Decompress data compressed by brotlicompress using the Brotli algorithm.

The decompressor uses GstAdapter to reassemble complete Brotli streams from arbitrary-sized input chunks (e.g. from filesrc). Brotli streams are self-delimiting, so no method property is required.

When the compressed stream carries original-caps (written by brotlicompress with GDP), the srcpad caps are restored automatically. When absent, caps must be provided downstream via a GDP depayloader or an explicit caps filter.

Examples

Direct pipeline (caps restored from original-caps):

... ! brotlicompress ! brotlidecompress ! ...

From file (no embedded caps; provide them downstream):

filesrc location=file.br ! brotlidecompress ! rawvideoparse ...

Note Corruption handling

Brotli has no end-to-end checksum (unlike zlib), so the outcome of data corruption depends on where in the stream the corrupted bytes land:

• Structural corruption: detected as a hard failure (ResultFailure), surfaced as a GStreamer flow error. The pipeline reports an error and no output is produced.

• Payload corruption that breaks stream framing: treated as an incomplete stream (NeedsMoreInput). The decompressor waits for more data that never arrives, no output is produced and no error is signalled.

• Payload corruption that still forms a valid stream: decoded silently with garbage output (ResultSuccess with wrong data). No error is signalled.

For integrity guarantees, wrap the stream with GDP or use an external checksum.
