* alsdec: limit avctx->bits_per_raw_sample to 32Andreas Cadhalpun2015-05-05
| | | | | | | | | avctx->bits_per_raw_sample is used in get_sbits_long, which only supports up to 32 bits. CC: libav-stable@libav.org Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* ffv1enc: Add const attribute to input frameVittorio Giovara2015-05-01
| | | | | | warning: assigning to 'AVFrame *' (aka 'struct AVFrame *') from 'const AVFrame *' (aka 'const struct AVFrame *') discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
* rawenc: properly allocate coded_frameAnton Khirnov2015-04-29

* h264: use properly allocated AVFramesAnton Khirnov2015-04-29
|
* h264: embed the DPB in the contextAnton Khirnov2015-04-29
| | | | | It now has a fixed size and is initialized only once, so there is no point in allocating it separately.
* h264: merge the init and reinit paths in update_thread_context()Anton Khirnov2015-04-29
| | | | | There is no real need to handle the init case specially, everything necessary is initialized in the reinit code as well.
* h264: drop the reinit parameter from init_slice_header()Anton Khirnov2015-04-29
| | | | | It is only used to decide whether to call free_tables(), but that function is safe to call on an uninitialized context as well.
* h264: update the current bit depth/chroma type in init_slice_header()Anton Khirnov2015-04-29
| | | | | With frame threading, it is currently only updated in the context where the change occurs, but not in any other contexts.
* h264: copy nal_length_size in update_thread_contextAnton Khirnov2015-04-29
| | | | | | It does not make sense to copy is_avc without copying this as well. This patch should not change anything for now, but will have an effect in later commits.
* h264: drop a comment that carries no useful informationAnton Khirnov2015-04-29
|
* h264: move freeing the escaped RBSP buffer to free_context()Anton Khirnov2015-04-29
| | | | | It does not logically belong in free_tables(), since it's not allocated in alloc_tables() and its size has nothing to do with the frame size.
* h264: eliminate ff_h264_set_parameter_from_sps()Anton Khirnov2015-04-29
| | | | | | | | | | | | | | That function currently does two things -- reinitializing the DSP contexts and setting low_delay based on the SPS values. The former more appropriately belongs in h264_slice_header_init(), while the latter only really makes sense in decode_slice_header(). The third call to ff_h264_set_parameter_from_sps(), done immediately after parsing a new SPS, appears to serve no useful purpose, so it is just dropped. Also, drop now unneeded H264Context.cur_chroma_format_idc.
* h264: move context reinit lower down in update_thread_context()Anton Khirnov2015-04-29
| | | | | It uses some fields from the SPS, which is not yet set where the reinit is called currently.
* h264: move the DPB init/uninit to init_context()/free_context()Anton Khirnov2015-04-29
| | | | | | | | | | Currently, the DPB is initialized in alloc_tables() and uninitialized in free_tables(), but those functions manage frame size-dependent variables, so DPB management does not logically belong in there. Since we want the init/uninit to happen exactly once per the context lifetime, init_context()/free_context() are the proper place for this code.
* h264: drop H264Context.ouputed_pocAnton Khirnov2015-04-29
| | | | It is only set, but never used for anything.
* h264: drop needs_reallocAnton Khirnov2015-04-29
| | | | It is not needed anymore since switching to refcounted frames.

* jpeglsenc: Mark codec as init-thread-safe and init-cleanupVittorio Giovara2015-04-28
| | | | Fixes a memory leak on init failure.
* jpeglsenc: Check memory allocationsVittorio Giovara2015-04-28
| | | | | Convert exisiting free functions to av_freep() to avoid accidental double frees, and always intialize all buffers to NULL.
* flacenc: Move a scratch buffer to struct used by the functionVittorio Giovara2015-04-28
| | | | | This avoids allocating/freeing memory at every function call, checking its return value, and carrying the error around.
