Also simplify it, move it to avio.c and make it always log the error.
This fixes for example the image2 muxer when used with an URL which also
contains the protocol:

A demuxer might have allocated memory while reading the header. If
reading the header was successfull and an error happens before returning
(e.g. when queueing the attached pictures), the read_close function
would have never been called, so that all those allocations would leak.

The Dash muxer uses submuxers and when one such submuxer has been allocated,
it is initially only stored in a temporary variable. Therefore it leaks

This commit improves returned error codes by forwarding error codes. In
some instances, the hardcoded returned error codes made no sense at all:
The normal error code for failure of av_new_packet() is AVERROR(ENOMEM),
yet there were instances where AVERROR(EIO) was returned.

Hi,
This filter allows editing hevc headers and change metadata. Most
modifications doesn't make sense for all multiple PS streams (even if they
are decodable): same crop for different resolutions, the same tick_rate for
different FR. Changing the PS id allows a wide range of stream compositions
Thanks, I will fix that. What's the formatter parameters for that? (AStyle
or other)

Hi,
This patch has the implementation for supporting frame duplication (doubling/
tripling) by FFmpeg's HEVC decoder based on the picture_structre SEI value
present in the encoded video.
picture_structure value of 7 implies doubling and 8 implies tripling. The value
of picture_structure is set
