| * 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.

| * lavc doxy: add AVPacket-related stuff to a separate doxy group.Anton Khirnov2012-04-091-33/+49
| | | | | | | | | | Also move AV_PKT_DATA_PARAM_CHANGE/AV_PKT_DATA_H263_MB_INFO to the proper place.

| * 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.

| | | | | | | | | | It's only used inside transcode_video() and there's no point in preserving it between subsequent calls. So use a local variable instead.

* | vf_scale: ensure the palette is set for output.Reimar Döffinger2012-04-097-8/+11
| | | | | | | | | | | | | | | | Since those are pseudo-palette formats, swscale does not write into data[1], swscale must initialize the palette properly itself. This lead to frames that actually decoded as all-gray before. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* | Mark GRAY8 format as pseudo-paletted.Reimar Döffinger2012-04-093-2/+3
| | | | | | | | | | | | | | | | | | | | | | This fixes that the GIF encoder crashes with it because it has no palette. And the arguments for the pseudopalette apply to gray8 as much as to RGB8 etc. In addition the changes required in lavfi should be needed anyway when adding support for RGB8 etc. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* | scale: fix slice rendering with conversion between pal/non-pal.Reimar Döffinger2012-04-091-2/+5
| | | | | | | | | | | | | | We can't use whether the input format is paletted to decide that the output format has a palette in data[1], too, that makes no sense. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* | RV20: try keeping aspect during resolution changes.Reimar Döffinger2012-04-091-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolution changes are usually only used to scale with network bandwidth, the (full) resolution specified in the RM header really is authoritative. While I am not sure this is the best solution, it is a conservative approach that still should fix the most common cases. In particular, it fixes aspect with the sample from trac issue #785 (in MPlayer, ffplay seems to just ignore sample aspect changes in mid-playback).

| | | | | | | | | | | | | | | | | | When decoding LATM, this function will not process extradata but a different buffer. It seems this was forgotten to update when LATM support was added. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
