This will allow writing the tag in several steps, needed for writing
attached pictures.

It has no need of full AVFormatContext.

Rename ff_id3v2_read_all to ff_id3v2_read().

it will be useful for attached pictures in ID3v2

It is not supposed to be set outside of lavc.

Fixes a divide by zero when the stored framerate is 0.

ProRes codes chroma blocks in 444 mode in different order than luma blocks,
so make both decoder and encoder read/write chroma blocks in right order.

Deprecate corresponding AVCodecContext field.

It's unused.

It's currently only used as temporary storage by the mov demuxer. Make
it use a local variable instead.

Deprecate corresponding AVCodecContext fields.

Deprecate CODEC_FLAG_CBP_RD.

Deprecate CODEC_FLAG_QP_RD.

Deprecate CODEC_FLAG2_STRICT_GOP.

Deprecate CODEC_FLAG2_SKIP_RD in favor of the corresponding mpv_flags
flag.

aacdec: Reshuffle functions so get_che() can call set_default_channel_config() and output_configure().

Seeking back on EOF will reset the EOF flag, causing us to re-enter
the loop to find the next marker in the ASF file, thus potentially
causing an infinite loop.

Splits at borders of cells are invalid, since it leaves one of the
cells with a width/height of zero. Also, propagate errors on buffer
allocation failures, so we don't continue decoding (which crashes).

Provide a way to wrap around the segment index so pseudostreaming
live through a web server and html5 browser is simpler.

Also ensure that 0 (disable) is a valid value across the options
providing wrap around.

WavPack has a comprehensive test suite, and a bunch

The index validation identifies these indexes as broken.
Signed-off-by: Martin Storsjö <martin@martin.st>

By validating the index entries while reading, we don't need to
seek at startup to validate the entries. If the error in the
index entries is not pointing to (our definition of) the start
of packets, and there is an index entry pointing at some of the
first packets after the metadata, the invalid index can be discarded
almost immediately.

This returns 200 OK for OPTIONS requests and 501 Not Implemented
for all other requests.

Even though this doesn't do much actual handling of the requests,
it makes the code properly identify server requests as such, instead
of interpreting it as a reply to the client's request as it did
before.

For encoding, AVCodecContext.frame_size is the number of input samples to
send to the encoder and does not necessarily correspond directly to the
timestamps of the output packets.
