| | | | | | | | | | | | | | No speex samples with non default frame sizes are known (to me) the official speexenc seems to only generate the 3 default ones. Thus it may be that the fuzzer samples where the first non default values encountered by the decoder.

* avformat/mov: add option max_stts_deltaGyan Doshi2021-12-31
| | | | | | | | | | | | | | | | Very high stts sample deltas may occasionally be intended but usually they are written in error or used to store a negative value for dts correction when treated as signed 32-bit integers. This option lets the user set an upper limit, beyond which the delta is clamped to 1. Values greater than the limit if negative when cast to int32 are used to adjust onward dts. Unit is the track time scale. Default is UINT_MAX - 48000*10 which allows upto a 10 second dts correction for 48 kHz audio streams while accommodating 99.9% of uint32 range.

* avdevice/dshow: select format with extended color infoDiederick Niehorster2021-12-24
| | | | | | | | | | | | | | | | | | | | | | Some DirectShow devices (Logitech C920 webcam) expose each DirectShow format they support twice, once without and once with extended color information. During format selection, both match, this patch ensures that the format with extended color information is selected if it is available, else it falls back to a matching format without such information. This also necessitated a new code path taken for default formats of a device (when user didn't request any specific video size, etc), because the default format may be one without extended color information when a twin with extended color information is also available. Getting the extended color information when available is important as it allows setting the color space, range, primaries, transfer characteristics and chroma location of the stream provided by dshow, enabling users to get more correct color automatically out of their device.

| | | | | | | | | | | | | | | | avdevice/dshow is a realtime device and as such does not support seeking. Therefore, its demuxer format should define the AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH and AVFMT_NO_BYTE_SEEK flags. With these flags set, attempting to seek (with, e.g., avformat_seek_file()) correctly yields -1 (operation not permitted) instead of -22 (invalid argument). This actually seems to apply to many other devices, at least the gdigrab, v4l2, vfwcap, x11grab, fbdev, kmsgrab and android_camera devices, from reading the source.
