Shouldn't the result of xmlEncodeEntitiesReentrant(NULL, root_url) be freed
with av_free or xmlFree?
xmlChar *tmp_str = NULL;
tmp_str = xmlEncodeEntitiesReentrant(NULL, root_url);
xmlNodeSetContent(node, tmp_str);
xmlFree(tmp_str);

When allocating the VAAPIEncodePicture, pic->input_surface can be
initialized right in the place. This movement simplifies the send_frame
logic and is the preparation for moving vaapi_encode_send_frame to the base
layer.

VAAPI and D3D12VA can share rate control configuration codes. Hence, it
can be moved to base layer for simplification.

I have no relation and none of the above.

This issue happens in the following case:
- unaligned PES and NAL encoding
- the first NAL of the access unit begins at the very end of a ts packet,
sometimes only the 0x00 of the trailing byte
(unfortunately, this is still conformant to the standards!)
- the video frame is so small (ex: typically
When PES are not aligned and a tiny nal-encoded frame is contained in a single
TS packet,
the first NAL startcode may be split by the PES boundary, making the packet
unworkable.
This patch shift the PES boundaries to avoid this.

Before this patch, the FFmpeg MXF parser correctly detects content with
2 fields in 1 AVPacket as e.g. interlaced 720x486 but the FFmpeg JPEG
2000 decoder reads the JPEG 2000 SIZ header without understanding that
the indicated height is the height of 1 field only so overwrites the
frame size in
The number of extra retries to get more than a single duration is
currently limited to 1 (see commit 77a0df4b5).
This patch raises this number of retries to 3 (amongst the overall 6 max
retries).
Exemple: this sample requires 3 retries to get all durations:

The `entries` value is read directly from the stream and used to
allocate memory. This change clamps `entries` to however many are
possible in the remaining atom or file size (whichever is smallest).

This adds support for cLLi and mDVc chunks in the PNG specification[1].

These chunks contain the Content Light Level Information and the
Mastering Display Color Volume information that FFmpeg already supports
as AVFrameSideData. This patch adds support for the png decoder to read
these chunks if present and attach the corresponding side data to the
decoded frame.
