* avcodec/utils: Only call codec->close if init has been calledAndreas Rheinhardt2020-09-29
| | | | | | | | | | | | | | | | | | | | avcodec_open2() also called the AVCodec's close function if an error happened before init had ever been called if the AVCodec has the FF_CODEC_CAP_INIT_CLEANUP flag set. This is against the documentation of said flag: "The codec allows calling the close function for deallocation even if the init function returned a failure." E.g. the SVQ3 decoder is not ready to be closed if init has never been called.

* Revert "avfilter/setparams: add FF_FILTER_FLAG_HWFRAME_AWARE"Mark Thompson2020-09-29
| | | | | | | This reverts commit 5bbf58ab876279ca1a5a2f30563f271c99b93e62. The setparams filters are not hwframe aware, so the default context passthrough behaviour is needed to allow using them with hardware frames.

| | | | | | | | | | | | | | | | certain circumstances It seems that in files where the BASF block isn't first, v1.1 ASF streams are allowed to be non-22050. Either this format is really inconsistent, or FX Fighter and Croc just ignored the sample rate field, requiring the v1.1 restriction in the first place. This bumps the version to 1.2 in these streams so they're not "corrected".

* avcodec/fraps: Use cached bitstream readerAndreas Rheinhardt2020-09-26
| | | | | | | | | | | | | | | This proved beneficial for performance: For the sample [1] the number of decicycles in one decode call decreased from 155851561 to 108158037 for Clang 10 and from 168270467 to 128847479 for GCC 9.3. For x86-32 compiled with GCC 9.3 and run on an x64 Haswell the number increased from 158405517 to 202215769, so that the cached bitstream reader is only enabled if HAVE_FAST_64BIT is set. These values are the average of 10 runs each looping five times over the input.

* avcodec/fraps: Use unchecked bitstream readerAndreas Rheinhardt2020-09-26
| | | | | | | | | | | | | | | | | The fraps decoder already checked for overreads manually (and errored out in this scenario), yet it still enabled implicit checks, leading to worse performance and more code size. This commit disables the implicit bitstream reader checks. For the sample [1] this improves performance from 195105896 to 155851561 decicycles for Clang 10 and from 222801887 to 168270467 decicycles when compiled with GCC 9.3.

* avcodec/utvideodec: Avoid qsort when creating Huffman tablesAndreas Rheinhardt2020-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ut video format uses Huffman trees which are only implicitly coded in the bitstream: Only the lengths of the codes are coded, the rest has to be inferred by the decoder according to the rule that the longer codes are to the left of shorter codes in the tree and on each level the symbols are descending from left to right. Because longer codes are to the left of shorter codes, one needs to know how many non-leaf nodes there are on each level in order to know the code of the next left-most leaf (which belongs to the highest symbol on that level). The current code does this by sorting the entries to be ascending according to length and (for entries with the same length) ascending according to their symbols. This array is then traversed in reverse order, so that the lowest level is dealt with first, so that the number of non-leaf nodes of the next higher level is known when processing said level. But this can also be calculated without sorting: Simply count how many leaf nodes there are on each level. Then one can calculate the number of non-leaf nodes on each level iteratively from the lowest level upwards: It is just half the number of nodes of the level below. This improves performance: For the sample from ticket #4044 the amount of decicycles for one call to build_huff() decreased from 1055489 to 446310 for Clang 10 and from 1080306 to 535155 for GCC 9.
