wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago

Reimar Döffinger	2aa8e33d7d	Fix nonsense MPEG-4 hwaccel code. Issues with the code: 1) The skip_bits_long breaks packed B-frames since we skip of the packed frame, even for VDPAU. 2) Calling ff_h263_find_resync_marker_reverse is nonsense for MPEG-4, and for H.263 the only code using this (vaapi_mpeg4) explicitly reverts this change! 3) mb_x/mb_y are always 0 when vaapi_mpeg4_decode_slice, so doing computations with them is just obfuscation 4) due to not updating mb_y the code would always go into the error resilience case, causing nonsense error messages and maybe further issues. While tested to fix the data provided to the decoder in case of VDPAU so it is the same as for the non-hwaccel code, the VA-API code was not tested to still work, and adding regression testing even as a quick hack is much more complicated for it.

Reimar Döffinger	f76b633a94	mpeg4dec: Ensure data is not clobbered too early. Avoid overwriting the bitstream buffer data before we have ended processing the frame. This is necessary to fix hwaccels which might try to use the buffer during the end_frame call. I am not sure but it is possible this could even trigger a use-after-free if the av_fast_malloc allocated a new buffer. This would require that decode_slice did not wind the bitstream forward all the way to the end, which does not currently happen in normal streams.

Reimar Döffinger	a39cd8766f	Fix multithreaded MPEG-4 decoding. Regression since `c10d498bfd`. Unfortunately ff_thread_get_format can only be called from a separate decode thread, running it during init will fail. Fixes for that are welcome, for now just revert back to calling avctx->get_format directly, which is correct but having to decide on a case-by-case basis which approach to use is a bit messy.
