* avplay: Add an option for not limiting the input buffer sizeMartin Storsjö2012-07-04
| | | | | | | | | | | | | | | | | | | | | | For reading from normal files on disk, the queue limits for demuxed data work fine, but for reading data from realtime streams, they mean we're not reading from the input stream at all once the queue limit has been reached. For TCP streams, this means that writing to the socket from the peer side blocks (potentially leading to the peer dropping data), and for UDP streams it means that our kernel might drop data. For some protocols/servers, the server initially sends a large burst with data to fill client side buffers, but once filled, we should keep reading to avoid dropping data. For all realtime streams, it IMO makes sense to just buffer as much as we get (rather in buffers in avplay.c than in OS level buffers). With this option set, the input thread should always be blocking waiting for more input data, never sleeping waiting for the decoder to consume data. Signed-off-by: Martin Storsjö <martin@martin.st>

* flacdec: allocate sample buffers with av_mallocMans Rullgard2012-07-04
| | | | | | | | | The buffers are only allocated once, although it can happen from any of a few different places, so there is no need to use realloc. Using av_malloc() ensures they are aligned suitably for SIMD optimisations. Signed-off-by: Mans Rullgard <mans@mansr.com>

* ismindex: Verify that all bitrate variants matchMartin Storsjö2012-07-03
| | | | | | | | | | In Smooth Streaming, the fragments are addressed by time, and the manifest only stores one list of time offests for all streams, so all streams need to have identical fragment offsets. Warn if this isn't the case, so that the user can fix the files instead of getting failures at runtime when the fragments can't be found. Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: do not disable av_always_inline with --enable-smallMans Rullgard2012-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, --enable-small turns av_always_inline into plain inline, which is more or less ignored by the compiler. While the intent of this is probably to reduce code size by avoiding some inlining, it has more far-reaching effects. We use av_always_inline in two situations: 1. The body of a function is smaller than the call overhead. Instances of these are abundant in libavutil, the bswap.h functions being good examples. 2. The function is a template relying on constant propagation through inlined calls for sane code generation. These are often found in motion compensation code. Both of these types of functions should be inlined even if targeting small code size. Although GCC has heuristics for detecting the first of these types, it is not always reliable, especially when the function uses inline assembler, which is often the reason for having those functions in the first place, so making it explicit is generally a good idea. The size increase from inlining template-type functions is usually much smaller than it seems due to different branches being mutually exclusive between the different invocations. The dead branches can, however, only be removed after inlining and constant propagation have been performed, which means the initial cost estimate for inlining these is much higher than is actually the case, resulting in GCC often making bad choices if left to its own devices. Furthermore, the GCC inliner limits how much it allows a function to grow due to automatic inlining of calls, and this appears to not take call overhead into account. When nested inlining is used, the limit may be hit before the innermost level is reached. In some cases, this has prevented inlining of type 1 functions as defined above, resulting in significant performance loss. Signed-off-by: Mans Rullgard <mans@mansr.com>
