  • avformat/mov : add option max_stts_delta

    avformat/mov : add option max_stts_delta

    Very high stts sample deltas may occasionally be intended but usually
    
they are written in error or used to store a negative value for dts correction
    
when treated as signed 32-bit integers.
    

    This option lets the user set an upper limit, beyond which the delta is clamped to 1.
    
Values greater than the limit if negative when cast to int32 are used to adjust onward dts.
    

    Unit is the track time scale. Default is UINT_MAX - 48000*10 which
    
allows upto a 10 second dts correction for 48 kHz audio streams while
    
accommodating 99.9% of uint32 range.

    libavutil/hwcontext_qsv : fix a bug for mapping vaapi frame to qsv

    The data stored in data[3] in VAAPI AVFrame is VASurfaceID while
    
the data stored in pair->first is the pointer of VASurfaceID, so
    
we need to do cast to make following commandline works :
    

    ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \

    - hwaccel_output_format vaapi -i input.264 \

    - vf "hwmap=derive_device=qsv,format=qsv" -c:v h264_qsv output.264

  • Revert "Disable warnings for casting pointers to integers, there is nothing wrong...

    20 novembre 2021, par Andreas Rheinhardt
    Revert "Disable warnings for casting pointers to integers, there is nothing wrong with that."

    This reverts commit 5258f64a14713499cf84840b3ab3a1ee7cdcaeb8.
    
The premise of said commit (that conversions from pointer to int
    
are ok) is wrong : C99/C11 6.3.2.3 5 : "Any pointer type may be converted
    
to an integer type. [...] If the result cannot be represented in the
    
integer type, the behavior is undefined." (C90 6.3.4 contains a similar
    
restriction.) So don't disable -Wpointer-to-int-cast.
