Place some START_TIMER invocations in separate blocks.
...
This fixes compilation failures related to START_TIMER/STOP_TIMER macros and
-Werror=declaration-after-statement. START_TIMER declares variables and thus
may not be placed after statements outside of a new block.

Drop ALT_ prefix from BITSTREAM_READER_LE name.

The prefix is a historic remnant that probably meant "alternative".

lavc: set defaults in internal codec frames
...
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.
