This header is unconditionally installed, even though the utility
functions defined by it may be missing from the built library.
A precedent set by e.g. libavcodec/qsv.h (and others) is to always
provide these functions by compiling stub functions in the absence of
CONFIG_*. Ma
I'm not sure we're on the same page, so let me try and clarify.

tracks. I'm using the command line option -map 0:m:handler_name:"" to
identify the tracks to copy. Given a single file this works as expected,

This is a per-file input option that adjusts an input's timestamps
with reference to another input, so that emitted packet timestamps
account for the difference between the start times of the two inputs.
Typical use case is to sync two or more live inputs such as from capture
devices. Both the tar
Same issues apply to it as to -shortest.

streams. The last output stream is limited to 8 frames. The current
code results in the first two output stre

Adds FEC/PLC support to libopus. The lost packets are detected as a
discontinuity in the audio stream. When a discontinuity is used, this
patch tries to decode the FEC data. If FEC data is present in the
packet, it is decoded, otherwise audio is re-created through PLC.
This patch is based on Stein
An estimation of packet loss is required by libopus to compute its FEC
data. Currently, this estimation is constant, and can not be changed
after configuration. This means an application using libopus through
ffmpeg can not adapt the packet loss estimation when the network
quality degrades.

Please find attached a new version of the patchset, with the required

The documentation specifies that it is set by the user
for encoders. Given that ff_dvvideo_init() is so extremely simple,
the fix consists of inlining the function into its two callers,
with setting chroma_sample_location omitted in dvenc.c.
This unfortunately leads to the color siting element wri

This is a per-file input option
When two formats lists cannot be merged, a scale filter is
auto-inserted. However, when it comes to hardware map, we have to
manually add a hwmap filter to do the conversion. This patch introduces
an auto hwmap filter to do the hwmap conversion automatically.

easier to add more auto filters. And it adds a loop to automatically insert
