Separate the code that searches for the option to use and the code that actually writes it. The writing code will be reused by the new options parser.

Fixes CVE-2012-2782.

Since we can't know which stride a custom get_buffer() implementation is going to use we have to allocate this scratch buffers after the linesize is known. It was pretty safe for 8 bit per pixel pixel formats since we always allocated memory for up to 16 bits per pixel. It broke hoever with cmdutis.c's alloc_buffer() and high pixel bit depth since it allocated larger edges than mpegvideo expected. Fixes fuzzed sample nasa-8s2.ts_s244342.

It is not posible to call get_buffer during frame-mt codec initialization. Libavformat might pass huge amounts of data as extradata after parsing broken files. The 'extradata' for the fuzzed sample sample_varPAR_s5374_r001-02.avi is 2.8M large and contains multiple slices.

It adds unnecessary complication for insignificant usability improvement. The user really should know if they'll need resampling compensation before opening the context. Note that only the documentation has changed. The current functionality will still work until the next major bump.

This makes it easier for receivers to decide what to do if data is lost. Refactor calculating the max payload size, to avoid hardcoding the header size in too many places, reducing the number of lines that have to be touched if the header is adjusted further. Signed-off-by:

Since a NAL_DPA can start a new frame it has to be handled before ff_thread_finish_setup is called.

This requires to move the avcodec_default_free_buffers() call to ff_MPV_common_end() since otherwise delayed pictures would get freed during a size change.

Direct rendering capable decoders call get_buffer() which will set the frame parameters. Prevents frames with wrong parameters when a decoder outputs delayed frames after a resolution or pixel format change.

The max_comp option is supposed to limit maximum compensation, but currently the clipped value is not actually used.
