Todo List

Global av_samples_alloc (uint8_t **audio_data, int *linesize, int nb_channels, int nb_samples, enum AVSampleFormat sample_fmt, int align)

return the size of the allocated buffer in case of success at the next bump

Global av_samples_fill_arrays (uint8_t **audio_data, int *linesize, const uint8_t *buf, int nb_channels, int nb_samples, enum AVSampleFormat sample_fmt, int align)

return minimum size in bytes required for the buffer in case of success at the next bump

Global avcodec_fill_audio_frame (AVFrame *frame, int nb_channels, enum AVSampleFormat sample_fmt, const uint8_t *buf, int buf_size, int align)

return the size in bytes required to store the samples in case of success, at the next libavutil bump

Global avformat_find_stream_info (AVFormatContext *ic, AVDictionary **options)

Let the user decide somehow what information is needed so that we do not waste time getting stuff the user does not need.

Global AVOption::help

What about other languages?

Global bitplane_decoding (uint8_t *data, int *raw_flag, VC1Context *v)

FIXME: Optimize

Global decode_colskip (uint8_t *plane, int width, int height, int stride, GetBitContext *gb)

FIXME: Optimize

Global eval_lpc_spectrum (const float *lsp, float cos_val, int order)

reuse code from Vorbis decoder: vorbis_floor0_decode

File f_ebur128.c

implement start/stop/reset through filter command injection

support other frequencies to avoid resampling

Global ff_rv34_get_start_offset (GetBitContext *gb, int blocks)

Maybe replace with ff_h263_decode_mba() ?

Global ff_rv34_get_start_offset (GetBitContext *gb, int blocks)

Maybe replace with ff_h263_decode_mba() ?

File jacosubdec.c

Support P[ALETTE] directive.

File libmodplug.c

better probing than extensions matching

Class OWDenoiseContext

try to change to int

try lifting based implementation

optimize optimize optimize

hard thresholding

use QP to decide filter strength

wavelet normalization / least squares optimal signal vs. noise thresholds

Global parse_presentation_segment (AVCodecContext *avctx, const uint8_t *buf, int buf_size, int64_t pts)

TODO: Implement cropping

Class RTSPState

Use AVIOContext instead of URLContext

Global rv34_dquant_tab [2][32]

Use with ff_modified_quant_tab from h263data.h.

Global rv34_mb_bits_sizes [6]

This is the same as ff_mba_length, maybe use it instead.

Global rv34_mb_max_sizes [6]

This is the same as ff_mba_max, maybe use it instead.

File src_movie.c

use direct rendering (no allocation of a new frame)

support a PTS correction mechanism

Group VC-1 VLC tables and defines

TODO move this into the context

Group VC-1 VLC tables and defines

TODO move this into the context

Global vc1_decode_frame (AVCodecContext *avctx, void *data, int *got_frame, AVPacket *avpkt)

TODO: Handle VC-1 IDUs (Transport level?)

Global vc1_decode_init (AVCodecContext *avctx)

TODO: Handle VC-1 IDUs (Transport level?)

TODO: Decypher remaining bits in extra_data

Class VC1Context

Change size wherever another size is more efficient Many members are only used for Advanced Profile

File webvttdec.c

need to support extended markups and cue settings

Global wma_lsp_to_curve (WMACodecContext *s, float *out, float *val_max_ptr, int n, float *lsp)

optimize it further with SSE/3Dnow
