Diego Biurrun abe655a472 Drop unnecessary prefix from *sink* variable and struct names. 2012-01-25 12:28:36 +01:00
Martin Storsjö 33ec9ef96d Add a tool for creating smooth streaming manifests 
It can also optionally split the file into individual fragments,
which allows it to be served from any web server without any
server side support.

Martin Storsjö 3b5d4428ac movenc: Write the sample rate instead of time scale in the stsd atom 
For ismv/isma, the time scale might not be the same as the sample
rate.

Martin Storsjö 6ca3856894 movenc: Add a separate start_pts 
This fixes calculation of trackDuration if the MOVIentry array
is cleared. This is required by the fragmentation support in the
next patch.

Ronald S. Bultje c3af52fa8b dsputil: use vertical component for drawing bottom edge. 
Current code only writes 8 pixels of vertical edge for YUV422, which
causes MC artifacts when subsequent frames use data from that edge.

Alex Converse efe68076da aacenc: Fix identification padding when the bitstream is already aligned. 2012-01-24 12:55:21 -08:00
Michael Niedermayer cdfe94c5ab aacenc: Write correct length for long identification strings. 
When the length is the escape value (15), the new length is calculated by
15 + get_bits(8) - 1.

Justin Ruggles b8dd555c63 aud: remove unneeded field, audio_stream_index from context 
There is only one stream, so it will always be index 0.
This also allows for removal of the private context.

Justin Ruggles be14a37066 aud: fix time stamp calculation for ADPCM IMA WS

Justin Ruggles 0e6a8b5cf7 aud: set pts_wrap_bits to 64. 
Time stamps are not read from the bitstream, so no wrapping is needed.

Justin Ruggles d481227c54 aud: support Westwood SND1 audio in AUD files. 
Fixes decoding of the handful of "death scream" samples from
"Command and Conquer" that use SND1. e.g.
http://samples.libav.org/game-formats/westwood-aud/nuyell1.aud

Justin Ruggles 02e7dbf5ad adpcm_ima_ws: fix stereo decoding 
Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for
VQA version 2.
 2012-01-24 14:13:46 -05:00
Justin Ruggles 220506d23f avcodec: add a new codec_id for CRYO APC IMA ADPCM. 
The stereo layout and extradata is significantly different from that in
Westwood IMA ADPCM, so a separate codec_id is warranted.

Fix setting of bit_rate and bits_per_coded_sample.

Justin Ruggles 5b4c562897 vqa: set time base to frame rate as coded in the header. 
According to Multimedia Wiki documentation, the frame rate is not always 15,
and the actual value can be found in the header.

Justin Ruggles 9ae846971f vqa: set packet duration. 
Also remove unused context field, audio_frame_counter.

Justin Ruggles e1ac69fa27 vqa: set stream start_time to 0. 
The format has no coded timestamps and must use packet durations to generate
them.

Anton Khirnov 1381e9bc92 lavc: postpone the removal of AVCodecContext.request_channels. 
Although it has been deprecated for a long time, its intended
replacement (request_channel_layout) is not actually used anywhere, so
request_channels is currently the only way to access that functionality.
