[FFmpeg-devel] [PATCH] hwcontext_vdpau: implement av_hwdevice_get_hwframe_constraints()

In addition, this does not allow creating frames contexts with sw_format for which no known transfer formats exist. In theory, we should check whether the chroma format (i.e. the sw_format) is supported at all by the vdpau driver, but checking for transfer formats has the same effect. Note that

Hi! Seeing 6e80079a it appears that the unstable period is not over yet. Vittorio posted a patch that introduces a temporary type to avoid breaking API, but that may not be relevant if the api currently unstable. Attached patch (inspired by Vittorio's RFC) passes fate with --disable-asm and does

Hysterically dcaenc uses own implementation of time->frequency transformation used by psychoacoustic. But actually function named fft in original dcaenc code is not fft. Power spectrum looks similar to mdct, and Alexander E. Patrakov told me it is MDCT. But for me it is still a bit strange,
