* avcodec/bytestream: fix warnings with signed/unsigned compare in bytestream.hDevin Heitmueller2023-04-021-5/+5
| | | | | | | | | | | | When including the header in decklink_enc.cpp it would be fed through the C++ compiler rather than the C compiler, which has more strict warnings when comparing signed/unsigned values. Make the local variables unsigned to match the arguments they are being passed for those functions.

* bytestream: Make get_bytes_left compatible with overreadAndreas Rheinhardt2020-03-061-2/+2
| | | | | | | | | | | | | bytestream2_get_bytes_left returns an unsigned int; as a result, it returns big positive numbers if an overread already happened, making it unsuitable for scenarios where one wants to allow this in a controlled way (because the buffer is actually padded so that no segfaults can happen). So change it to return an ordinary int. Also, bytestream2_get_bytes_left_p has been modified in the same way.

* avcodec/bytestream: check for AV_HAVE_BIGENDIAN instead of HAVE_BIGENDIANJames Almer2017-03-231-1/+1
| | | | | No need to include config.h for HAVE_BIGENDIAN when libavutil/avconfig.h is already included.

| * bytestream2: set the reader to the end when reading more than availableAnton Khirnov2015-07-121-1/+3
| | | | | | | | | | | | | | | | This prevents possible infinite loops with the calling code along the lines of while (bytestream2_get_bytes_left()) { ... }, where the reader does not advance. CC: libav-stable@libav.org
