Carl Eugen Hoyos	9c069bf71a	lavc/hapdec: Use correct no-transparency colour space. Reviewed-by: Tom Butterworth	9 years ago
Michael Niedermayer	205c31b301	avcodec/hapdec: Check section_size for non negativity in parse_section_header() Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Tom Butterworth	3ee217853a	Support the Hap chunked frame format Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Tom Butterworth	43dd004747	hap: Move some per-stream setup into decoder init rather than per-frame This change will reject frames with a texture type which does not match the stream description. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Michael Niedermayer	5da90d7ec3	avcodec/hapdec: Check that there is sufficient input data Fixes Ticket4729 Found-by: ami_stuff Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Tom Butterworth	083cbc930d	snappy: Refactor so ff_snappy_uncompress() uses an existing buffer Some uses of Snappy require uncompressing to positions within an existing buffer. Also adds a function to get the uncompressed length of Snappy data.	10 years ago
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
Tom Butterworth	c7e6443441	Support the Hap chunked frame format Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Tom Butterworth	5d0616ce0e	avcodec/hapdec: log reason for failure when texture type doesn't match stream Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Luca Barbato	977105407c	hap: Decode using optimal slices sizes Enjoy some cache locality and use less threads. About 5x speedup (from 60ms to 12ms to decode a 4k frame). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Tom Butterworth	6b96c70f2d	avcodec/hapdec: don't log texture format every frame, do it once per decode session Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
