Currently only flv and asf decoders attempt to use pb->read_seek,
by calling avio_read_seek() expliclity.
This change allows avformat users to specify a custom AVIOContext
with a read_seek callback, and have it be used with any format
whenever av_seek_frame() is invo
From: Aman Gupta
Previously, the initial seek position was recorded into
old_offset at the beginning of avformat_find_stream_info(),
and passed into estimate_timings(). In the case of mpegts
with a known filesize, it was further passed into
estimate_timings_from_pts() which called avio_seek

Previously the code assumed that stream_identifier was unique per stream
in the PMT, as suggested by the spec. However, I found some samples from
Finland MTV3 where this is not the case.

When using `ffprobe -show_format -show_streams -show_packets`,
it makes more sense to omit static data about the file format
and streams before the long list of packets instead of at the
end.

Integer overflow in the Q16 framerate calculation was sending
invalid values to the OMX encoder.
On the RPI4, this manifested as bitrate controls being ignored
on video streams with 6/1001 framerates. Video streams with
3/1001 framerates were not affected.

This allows the cli to create a dummy drm hwcontext
that can be shared between the v4l2 decoder/scaler/encoder.
This is especially useful on older RPI3 where /dev/dri devices
are not available in the default configuration.

This patchset enables a zero-copy hardware accelerated
decode+scale+encode pipeline on the RPI4 via V4L2. It also
includes various patches submitted to ffmpeg-devel in the
past and from LibreELEC's ffmpeg fork.
The V4L2 decoders can either output software pixel formats,

On the RPI, three different /dev/video devices exist (decoder, scaler, encoder).
When probing the devices in order, the originally requested pix fmt
would be mutated causing the wrong one to be chosen when a matching
device was finally found.

Without this ffmpeg will attempt to copy the dts from the
most recently enqueued packet into the most recently dequeued
frame, which does not account for the buffering inside v4l2

In rare circumstances, if the codec is not configured with the
proper parameters the input buffers can be allocated with a size
that's too small to hold an individual packet. Since MediaCodec

valid to split dat
