1db6437f6c wmapro: fix strict-aliasing violations by using av_alias32 
Also fix some undefined unsigned/signed conversions.

5b8009f4c8 apedec: do not keep incrementing the input data pointer past the end of the 
buffer during entropy decoding.

The pointer address could overflow, which would likely segfault. Instead set
the context error flag to indicate that the decoder tried to read past the
end of the packet data.

fd244ae3a0 apedec: use unsigned int for offset 
avoids implementation-defined unsigned-to-signed conversion and simplifies
the bounds checking.

The variable is not used anymore at that point.

2cab578489 apedec: use unsigned int for 'nblocks' and make sure that it's within int range 2011-10-28 11:47:27 -04:00

b7e5145759 apedec: do not set s->samples until after validation. 
This prevents errors and/or invalid writes in the next decode call due to
s->samples still being negative.

a2faa95151 lavf: make some seeking functions private 
Specifically av_update_cur_dts(), av_seek_frame_binary() and
av_gen_search().

They are not supposed to be called outside lavf.

512557b291 avcodec: remove avcodec_parse_frame and deprecate associated elements. 
The documentation for CODEC_CAP_PARSE_ONLY and AVCodecContext.parse_only
indicates that they are utilized through avcodec_parse_frame(), which was
never actually implemented.

c17e534f2e mpegaudiodec: remove frame_count field from MPADecodeContext. 
Its functionality was removed several years ago, so it doesn't do anything.
AVCodecContext.frame_number could serve the same purpose if someone
wants to debug the frame count.

4be1e1dfa7 mpegaudiodec: Skip only bad frames instead of the whole packet. 
On frame decoding failure, return an error if the frame is the same size as
the whole packet, otherwise just log an error message and return the number
of bytes consumed.

345d15d2f9 libopencore-amr: remove unneeded buf_size==0 check. 
avcodec_decode_audio3() already checks it before sending the packet to the
decoder.

blocks.

0093f96d34 pcmdec: return buf_size instead of src-buf. 
The values will always be the same, so this change eliminates an unneeded
variable. It also gets rid of the need to reset src when memcpy() is used.

85579b6381 avcodec: remove the Zork PCM encoder. 
The Zork PCM decoder does not decode the 1 sample we have correctly, therefore
the encoder based on the decoder is also incorrect. There is no good reason to
keep the encoder.
