* rtmp: Support AMF_DATA_TYPE_MIXEDARRAYLuca Barbato2013-09-22
| | | | | | | | | And fix the AMF_DATA_TYPE_ARRAY parsing while at it. A MIXEDARRAY type, as the ARRAY, store the number of elements in an uint32 before the list. The ARRAY is strict and does not have an OBJECT terminator, MIXEDARRAY behaves like an OBJECT type and a different than stated number of element can be present.
* rtmp: Support reading interleaved chunks.Josh Allmann2013-09-17
| | | | | | | | | | | | | | | A given packet won't always come in contiguously; sometimes they may be broken up on chunk boundaries by packets of another channel. This support primarily involves tracking information about the data that's been read, so the reader can pick up where it left off for a given channel. As a side effect, we no longer over-report the bytes read if (toread = MIN(size, chunk_size)) == size Signed-off-by: Martin Storsjö <martin@martin.st>

* rtmp: fix buffer overflows in ff_amf_tag_contents()Xi Wang2013-01-23
| | | | | | | | | | | | | | A negative `size' will bypass FFMIN(). In the subsequent memcpy() call, `size' will be considered as a large positive value, leading to a buffer overflow. Change the type of `size' to unsigned int to avoid buffer overflow, and simplify overflow checks accordingly. Also change a literal buffer size to use sizeof, and limit the amount of data copied in another memcpy call as well.

* rtmp: fix multiple broken overflow checksXi Wang2013-01-23
| | | | | | | | | | | | Sanity checks like `data + size >= data_end || data + size < data' are broken, because `data + size < data' assumes pointer overflow, which is undefined behavior in C. Many compilers such as gcc/clang optimize such checks away. Use `size < 0 || size >= data_end - data' instead.

* rtmp: Read and handle incoming packets while writing dataSamuel Pitoiset2012-06-14
| | | | | | | | | | | This makes sure all incoming packets are read and handled (and reacted to) while sending an FLV stream over RTMP to a server. If there were enough incoming data to fill the TCP buffers, this could potentially make things block at unexpected places. For the upcoming RTMPT support, we need to consume all incoming data before we can send the next request. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavu: replace int/float punning functionsMans Rullgard2011-12-11
| | | | | | | | | | | | | | | | | | The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>

* rtmp: Don't try to do av_malloc(0)Martin Storsjö2011-05-25
| | | | | | | | | Some received packets can have size 0. The return value from av_malloc(0) may be NULL, which is ok if the size was 0. On OS X, however, the returned pointer is non-null but leads to crashes when trying to free it. Signed-off-by: Martin Storsjö <martin@martin.st>
