Tom Butterworth	bd6fa80d56	avcodec/hap: add "compressor" option to Hap encoder to disable secondary compression The secondary compression in Hap is optional, this change exposes that option to the user as some use-cases favour higher bitrate files to reduce workload decoding. Adds "none" or "snappy" as options for "compressor". Selecting "none" disregards "chunks" option: chunking is only of benefit decompressing Snappy.

Tom Butterworth	ae5a8dca67	hap: Fix slice size computation A bug was introduced in `977105407c` whereby when frame height wasn't divisible by the number of threads, pixels would be omitted from the bottom rows during decode. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
