This commit actually enables subtitle filtering in ffmpeg by
sending and receiving subtitle frames to and from a filtergraph.
The heartbeat functionality from the previous sub2video implementation
is retained and applied to all subtitle frames (bitmap, text, ..).

The check for m->size >= 0xF000 is intended to avoid skipping too much
garbage data between JPEG frames in test_roman (thus missing next SOI),
but it erroneously also skips valid markers between SOI and SOS. Instead
of this, we should simply skip parsing markers other than SOI after EOI.
That way,

Due to reasons, mpv doesn't pass filename when probing. mpv also sets
default probescore threshold to 26. Since the current jpeg_probe
implementation returns 25 until EOI, it means that the whole image needs
to be probed to succeed. Worse, the whole image is not passed at once;

Roughly doubles webp performance for common applications (ffmpeg,
ffprobe, mpv) due to speeding up avformat_find_stream_info.
Lossy needs no patches since vp8.c already implements skip_frame.
Lossless needs hook to understand skip_frame. Also the "image data not
found" message is fixed, which was

This way we can pass explicit modifiers in. Sometimes the
modifier matters for the number of memory planes that
libva accepts, in particular when dealing with
driver-compressed textures. Furthermore the driver might
not actually be able to determine the implicit modifier

Vulkan will map nv12 to R8 and GR88, so add this map to vaapi to support

The vaapi can import external frame, but the planes of the external
frames should be in the same drm object. A new option "contiguous_planes"
is added to device. This flag tells device to allocate places in one
memory. When device is derived from vaapi this flag will be enabled.
