* avcodec/asvenc: Avoid reversing output data twiceAndreas Rheinhardt2020-10-18
| | | | | | | | | | | | | | | | The ASUS V2 format is designed for a little-endian bitstream reader, yet our encoder used an ordinary big-endian bitstream writer to write it; the bits of every byte were swapped at the end and some data (namely the numbers not in static tables) had to be bitreversed before writing it at all, so that it would be reversed twice. This commit stops doing so; instead, a little-endian bitstream writer is used. This also necessitated to switch certain static tables, which required trivial modifications to the decoder (that uses the same tables).

* avcodec/asvdec: Avoid reversing input data twiceAndreas Rheinhardt2020-10-18
| | | | | | | | | | Up until now the ASV2 decoder used an ordinary big-endian bitreader to read data actually destined for a little-endian bitreader; this is done by reversing the whole input packet bitwise, using the big-endian bigreader and reversing (and shifting) the result again. This commit stops this and instead uses a little-endian bitreader directly. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/movtextenc: fix writing to bytestream on BE archesAndriy Gelman2020-10-15
| | | | | | | | | | | | | | | | | | Fixes fate-binsub-movtextenc on PPC64 Currently tags are written in reverse order on BE arches. This is fixed by using MKBETAG() and AV_RB32() to be arch agnostics. Also s->font_count is of type int. On BE arches with 32bit int, count = AV_RB16(&s->font_count) will read two most significant bytes instead of the least significant bytes. This is fixed by assigning s->font_count to count first. The final change is modifying the type of len. On BE arches the most significant byte of the int was written instead of the least significant byte.

* avcodec/webp: Use LE VLC table for LE bitstream readerAndreas Rheinhardt2020-10-12
| | | | | | | | | | | | | | | | The WebP format uses Huffman tables and the decoder therefore uses VLC tables. Given that WebP is a LE format, a LE bitreader is used; yet the VLC table is not created for a LE reader (the process used to create the tables puts the last bit to be read in the lowest bit) and therefore custom code for reading the VLCs that reverses the bits read is used instead of get_vlc2(). This commit changes this to use a table designed for LE bitreader which allows to use get_vlc2() directly. The necessary reversing of the codes is delegated to ff_init_vlc_sparse() (and is therefore only done during init and not when actually reading the VLCs).

| | | | | | | | | This is easily possible because ff_init_vlc_sparse() already transforms both LE as well as BE codes to a normal form internally before processing them further.

* avcodec/indeo2: Remove #ifdef BITSTREAM_READER_LE cruftAndreas Rheinhardt2020-10-12
| | | | | | | | | | | | | | | | Before the LE bitstream reader was used in the Indeo 2 decoder, a standard BE bitstream reader with swapped bits was used; when the LE bitstream reader was added, the old code was only #ifdef'ed away and not removed. Said code has several problems: It modifies the input packet without ensuring that the packet is indeed writable; and it doesn't work since 09c4e5c5988c0037d108c5fc2a137d9ad488f7f4 because said commit removed the BE table used to initialize the VLC table. So just remove this cruft from the actual decoder, too. Also use INIT_LE_VLC_STATIC while at it.

| | | | | | | | | | It currently uses 9 bits per table, but there are no codes with nine bits at all, while there are codes with eight, ten and eleven bits.
