Andreas Rheinhardt	d2308b9237	avcodec/bink: Only keep what is used from HpelDSPContext Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	ceeba2ac2b	avcodec/bink: Combine allocations of arrays into one Saves allocations, checks for the allocations as well as frees. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	4f67288948	avcodec/bink: Fix memleak upon init failure The init function first allocates an AVFrame and then some buffers; if one of the buffers couldn't be allocated, the AVFrame leaks. Solve this by setting the FF_CODEC_CAP_INIT_CLEANUP flag. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
James Almer	9ea6d2149e	avcodec/decode: add a flags parameter to ff_reget_buffer() Some decoders may not need a writable buffer in some specific cases, but only a reference to the existing buffer with updated frame properties instead, for the purpose of returning duplicate frames. For this, the FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential allocations and buffer copies when they are not needed.
