Reimar Döffinger	3b55429d56	Add and use av_fast_padded_malloc. The same as av_fast_malloc but uses av_mallocz and keeps extra always-0 padding. This does not mean the memory will be 0-initialized after each call, but actually only after each growth of the buffer. However this makes sure that a) all data anywhere in the buffer is always initialized b) the padding is always 0 c) the user does not have to bother with adding the padding themselves Fixes another valgrind warning about use of uninitialized data, this time with fate-vsynth1-jpegls.

Alex Converse	4bf3c8f226	mov: Don't stick the QuickTime field ordering atom in extradata. The 'fiel' atoms can be found in H.264 tracks clobbering the extradata. MJPEG supports non field based extradata, and this data should be preserved when copying.	13 years ago

Reimar Döffinger	55a1fe7a80	Reset cur_scan at more appropriate places. Reset it when we actually process an EOI, not when we actually decide to ignore it for bug-workarounds, and reset it on SOF to make it more reliable in case of missing EOI.
