Anton Khirnov	8733799392	h263dec: sanitize a condition. Call ff_mpeg4_decode_picture_header() only when the decoder has the MPEG4 codec id, not based on a vaguely related value of h263_pred.	11 years ago

Martin Storsjö	8812a8057f	h263dec: Remove a hack that can cause infinite loops The actual usefulness of the hack is not known, and it does cause infinite loops with some broken input files. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	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.

Reimar Döffinger	c10d498bfd	Add thread-safe wrapper for get_format(). Just like get_buffer, get_format should not be called from a different thread if thread_safe_callbacks is not set. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Janne Grunau	05fa79b844	hwaccel: fix use with frame based multithreading Allows use of AVHWAccel based decoders with frame based multithreading. The decoders will be forced into an non-concurrent mode by delaying ff_thread_finish_setup() calls after decoding of the current frame is finished. This wastes memory by unnecessarily using multiple threads and thus copies of the decoder context but allows seamless switching between hardware accelerated and frame threaded software decoding when the hardware decoder does not support the stream.	12 years ago

Ronald S. Bultje	8d061989dd	lavc: Split out ff_hwaccel_pixfmt_list_420[] over individual codecs Not all hwaccels implement all codecs, so using one single list for multiple such codecs means some codecs will be represented in the list, even though they don't actually handle that codec.
