Andreas Rheinhardt acbd950ed2 avformat/wtvdec: Forward errors when reading packet wtvfile_read_packet did not abide by the requirements of an AVIOContext's read_packet-function: If it did not read anything, it returned zero, which currently leads to a warning in read_packet_wrapper in aviobuf.c. Said warning will be an av_assert2 as soon as FF_API_OLD_AVIO_EOF_0 is zero (probably the next major version bump). So instead forward the error code from the underlying protocol. This error/assert is triggered in the wtv-demux FATE test.
