James Almer	a0739e8a16	avcodec/nuv: prevent frame copying when outputting duplicate frames Signed-off-by: James Almer <jamrial@gmail.com>	5 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.

Janne Grunau	859a579e9b	nuv: check RTjpeg header for validity CC: libav-stable@libav.org	12 years ago
Janne Grunau	110d015ad4	Revert "nuv: check per-frame header for validity." The check is bogus since the nuv frameheader is already skipped and the (decompressed) RTjpeg header is checked. This reverts commit `f6afacdb3b`. CC: libav-stable@libav.org	12 years ago

Reimar Döffinger	95e1dfee76	nuv: Fix combination of size changes and LZO compression. There were multiple issues, for example might we have to re-run the decompression when the size of the buffer increased, we should always use a decompression buffer large enough for the header (so we do not get stuck when the size is too small).
