zlibcompress

Compress data using the zlib algorithm (includes checksum).

The srcpad caps will be application/x-zlib-compressed with an original-caps field carrying the sinkpad caps.

Unless the compressed stream will be multiplexed into a container, using the GStreamer Data Protocol (GDP) is recommended so that caps are preserved in-band and zlibdecompress can restore them without out-of-band signalling.

Examples

Using GDP (caps preserved in-band)

... ! zlibcompress ! gdppay ! filesink location=/path/to/file

Without GDP

... ! zlibcompress ! filesink location=/path/to/file

SECTION:element-deflatecompress

Compress data using the deflate algorithm (no checksum).

The srcpad caps will be application/x-deflate-compressed with an original-caps field carrying the sinkpad caps.

Unless the compressed stream will be multiplexed into a container, using the GStreamer Data Protocol (GDP) is recommended so that caps are preserved in-band and deflatedecompress can restore them without out-of-band signalling.

Examples

Using GDP (caps preserved in-band)

... ! deflatecompress ! gdppay ! filesink location=/path/to/file

Without GDP

... ! deflatecompress ! filesink location=/path/to/file
