wm4	8b6136d3d1	vaapi: switch ff_vaapi_get_surface_id from Picture to AVFrame Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
wm4	1b1094a19d	vdpau: switch ff_vdpau_get_surface_id from Picture to AVFrame This gets rid of aliasing completely unrelated structs to Picture. Fixes the remaining compilation warnings in the vdpau code. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
wm4	7948a51b5c	vdpau: don't assume Picture and H264Picture are the same The code passed H264Picture* and Picture*, and assumed the hwaccel_picture_private field was in the same place in both structs. Somehow this happened to work in Libav, but broke in FFmpeg (and probably subtly breaks in Libav too). Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Michael Niedermayer	8ab8070784	avcodec/utils: fix sizeof(AVFrame) dependence in avcodec_encode_audio2() This is a bit tricky, we allocate a correctly sized AVFrame but then only copy the compile time AVFrame size, this is to ensure that user applications which do not use the correct av frame API dont end with out of array reads. Note, applications using the correct API have set extended_data and the changed code will never be executed for them. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
