Andreas Rheinhardt	354ba64f40	avcodec/mpc7: Reduce size of tables used to initialize VLCs By switching to ff_init_vlc_from_lengths() one can replace tables of codes of type uint16_t with tables of symbols of type uint8_t, saving space. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	16bb8247b4	avcodec/mpegaudiodsp: Make initializing synth windows thread-safe These arrays are used by the Musepack decoders, the MPEG audio decoders as well as qdm2 and up until now, these arrays might be initialized more than once, leading to potential data races as well as unnecessary initializations. Therefore this commit ensures that each array will only be initialized once. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	158f7df5e6	avcodec/mpc7, mpc7data: Avoid gaps in array The Musepack decoder uses static VLC tables to parse the bitstream. There are 14 different quant tables VLCs and each of them has a varying number of codes. The maximum number is 63, the average number is 25.3. Up until now, the array containing the raw data was of type uint16_t [7][2][64 * 2] (the 14 tables come in pairs of two, hence [7][2] instead of [14]) and from this it follows that there were large gaps in said array. This commit changes this by making it a continuous array instead. Doing so saves about 2KB.

Andreas Rheinhardt	bec4e15859	avcodec/mpc7, mpc7data: Make overlong arrays smaller For the VLC table arrays in mpc7_decode_init() this fixes a regression introduced in `1e40dc920a`. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
Andreas Rheinhardt	1e40dc920a	avcodec/mpc7: Don't pretend initializing static VLC tables can fail It can't if one hasn't made a mistake at calculating the sizes; and this is checked by asserts/aborts.

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
