* swr: set AV_OPT_FLAG_AUDIO_PARAM for the AVOptionsMichael Niedermayer2012-04-261-23/+25
| | | | Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* fix swr_convert buffering of packed audioAndrew Wason2012-04-211-3/+5
| | | | | | | | | | | | swr_convert is not properly buffering packed input audio when the output is not large enough, and when resampling is not actually needed (same samplerate and no SWR_FLAG_RESAMPLE). buf_set() is only handling the first channel and leaving the others as-is. Sample program to reproduce the problem is here https://gist.github.com/2431768 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* swr: add a swr_flags AVOptionMichael Niedermayer2012-04-111-0/+1
| | | | | | | Using swr_flags instead of plain flags will avoid conflicts that arise with plain flags and multiple libs (which all have AVOption flags) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* swr: fix invalid sample format message.Clément Bœsch2011-11-241-2/+2
| | | | | If the sample format is invalid, av_get_sample_fmt_name() will always return NULL.
* swr: use native planar sample formats.Clément Bœsch2011-11-241-4/+4
|
* swr: fix test program.Clément Bœsch2011-11-241-0/+1
| | | | | | | The number of used channels need to be reset to zero when swr_alloc_set_opts() is called successive times. This is a regression introduced in c8136ebd.
* swr: change minimum I/O channel count to zero.Clément Bœsch2011-11-201-2/+2
| | | | | This will silence the warning of av_set_opt_int() in swr for input/output channels when the layout is not yet defined (or supported).
* swr: move code to avoid resample forward declaration.Clément Bœsch2011-11-171-93/+91

* swr: introduce a public function to customize the channel mapping.Clément Bœsch2011-11-171-3/+8

|
* swr: make audio convert code explicitely private.Clément Bœsch2011-11-171-15/+15
| | | | Only what's declared in libswresample/swresample.h is public.

* swr: replace deprecated av_opt_set_defaults2() with av_opt_set_defaults().Clément Bœsch2011-11-161-1/+1

* swr: replace deprecated av_get_bits_per_sample_fmt() with ↵Clément Bœsch2011-11-161-3/+3
| | | | av_get_bytes_per_sample().
* swr: use designated initializers for the class.Clément Bœsch2011-11-161-1/+8
|
* swr: set the default used_ch_count value to zero.Clément Bœsch2011-11-141-2/+1
| | | | | | | This allows an appropriate behaviour when it is not specified (fallback to the number of input channels). Fixes Ticket523
* ffmpeg: add -map_channel option.Clément Bœsch2011-11-041-9/+23
