* | | 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>

| * | rv40dsp x86: use only one register, for both increment and loop counterChristophe GISQUET2012-04-101-23/+20

| * | rv40dsp: implement prescaled versions for biweight.Christophe GISQUET2012-04-107-79/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quite often, the original weights are multiple of 512. By prescaling them by 1/512 when they are computed (once per frame), no intermediate shifting is needed, and no prescaling on each call either. The x86 code already used that trick.

| * | avconv: use default channel layouts when they are unknownJustin Ruggles2012-04-106-5/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | If either input or output layout is known and the channel counts match, use the known layout for both. Otherwise choose the default layout based on av_get_default_channel_layout(). Changed some FATE references due to some WAVE files now having a non-zero channel mask.
| * | avconv: parse channel layout stringJustin Ruggles2012-04-101-0/+36
| | | | | | | | | | | | | | | This allows the user to use channel layout names instead of having to use the channel mask values.

| * | mem: Consistently return NULL for av_malloc(0)Martin Storsjö2012-04-101-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Plain POSIX malloc(0) is allowed to return either NULL or a non-NULL pointer. The calling code should be ready to handle a NULL return as a correct return (instead of a failure) if the size to allocate was 0 - this makes sure the condition is handled in a consistent way across platforms. This also avoids calling posix_memalign(&ptr, 32, 0) on OS X, which returns an invalid pointer (a non-NULL pointer that causes crashes when passed to av_free). Abort in debug mode, to help track down issues related to incorrect handling of this case. Signed-off-by: Martin Storsjö <martin@martin.st>
| * | vf_overlay: implement poll_frame()Anton Khirnov2012-04-091-1/+14
| | | | | | | | | | | | | | | | | | Signal that it can output a frame when there are frames on the main input and EOF on the overlay input, but a frame is buffered -- e.g. single picture overlay.

| * | lavc doxy: replace \ with /Anton Khirnov2012-04-091-1/+1
| | | | | | | | | | | | | | | It's the more proper symbol to use and it prevents doxygen from thinking it's a command.

| * | avconv: allow '-async -1' to disable timestamp sync for audio encodingJustin Ruggles2012-04-091-2/+2
| | | | | | | | | | | | | | | | | | This will allow a workaround for cases where input timestamps are invalid or when decoder delay of 1 packet or more confuses avconv into using the wrong timestamps as a sync reference.
