| * png_parser: Fix parsing on big endianMartin Storsjö2013-12-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Since pc.state is populated by shifting in from the end of the 32 bit word, the content within pc.state is already in native endian and should not be read with the AV_R{L,B} functions. This was already done correctly for state64 above. This fixes the fate-corepng test on big endian. Signed-off-by: Martin Storsjö <martin@martin.st>

* | avcodec/aacdec: default to non-wide 7.1 in non-strict modeAnssi Hannula2013-12-181-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AAC specification has 7.1(wide) as a default layout for 8-channel streams (channel config 7). However, at least Nero AAC encoder encodes non-wide 7.1 streams using the default channel config 7, mapping the side channels of the original audio stream to the second AAC_CHANNEL_FRONT pair in the AAC stream. Similarly, e.g. FAAD decodes the second AAC_CHANNEL_FRONT pair as side channels, therefore decoding the incorrect streams as if they were correct (and as the encoder intended). FFmpeg currently decodes such files by-the-spec, i.e. after decoding the original front pair will be in AV_CH_FRONT_x_OF_CENTER and the original side pair will be in AV_CH_FRONT_x. As actual intended 7.1(wide) streams are very rare while misencoded 7.1 files actually exist in the wild, default to assuming a 7.1 layout was intended unless in strict mode. Fixes playback of e.g. 8_Channel_ID.m4a in samples. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | | | | | | | Its possible to implement this with a few lines less code but it then would flip the order of the list and require registration of external codecs to be done first, also it could break user applications due to this.
