Rafaël Carré	91d4cfb812	apedec: do not buffer decoded samples over AVPackets Only consume an AVPacket when all the samples have been read. When the rate of samples output is limited (by the default value of max_samples), consuming the first packet immediately will cause timing problems: - The first packet with PTS 0 will output 4608 samples and be consumed entirely - The second packet with PTS 64 will output the remaining samples (typically, a lot, that's why max_samples exist) until the decoded samples of the first packet have been exhausted, at which point the samples of the second packet will be decoded and output when av_decode_frame is called with the next packet). That means there's a PTS jump since the first packet is 'decoded' immediately, which can be seen with avplay or mplayer: the timing jumps immediately to 6.2s (which is the size of a packet).

Kostya Shishkov	9652d4fcfc	ape: provide two additional bytes in buffer for old MAC versions Range coder in 3.90-3.95 overread two bytes in the final normalize.	12 years ago
Kostya Shishkov	b164d66e35	ape: make version-dependent decoding functions called via pointers This will help in supporting old versions, e.g. version 3.93 uses the same range coder but different predictor and version 3.82 uses different range coder and predictor. Also this should not make decoding newer versions slower by introducing additional checks on versions.	12 years ago

Justin Ruggles	37390d5cca	apedec: allow the user to set the maximum number of output samples per call It makes sense in some cases to split up the output packet to save on memory usage (ape frames can be very large), but the current/default size is arbitrary. Allowing the user to configure this gives more flexibility and requires minimal additional code.	13 years ago

Justin Ruggles	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.

Justin Ruggles	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.	13 years ago
