| * avio: Add const qualifiers to ffio_read_indirectBen Avison2013-08-08
| | | | | | | | | | | | | | This provides at least some protection against potential accidental corruption of AVIO buffer workspace. Signed-off-by: Martin Storsjö <martin@martin.st>

| * avio: Add an internal function for reading without copyingBen Avison2013-08-05

* | avformat: Append data in fill_buffer() when possibleMichael Niedermayer2013-07-04
| | | | | | | | | | | | | | | | | | Data is appended in fill_buffer() when there is sufficient space left and the data pointer only reset when needed. Previously the data pointer was more often reset, loosing more seekback space than otherwise needed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| * aviobuf: Partial support for reading in read/write contextsMartin Storsjö2013-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, aviocontexts are used either in pure-read or pure-write mode - full read/write mode doesn't work well (and implementing it is a much larger, not totally trivial change). This patch allows using avio_read and ffio_read_partial on read/write aviocontexts, where the read operations are passed through directly unbuffered, while writes are buffered as usual. This is enough to support the operations needed by packet based data transfer like in udp/rtp, where aviocontext is the only public API for hooking up custom IO.

| | | | | | | | | | | | | | Fixes an invalid free() with ass in avi. The sample in bug 98 passes parts of AVPacket.data as buffer for the AVIOContext. Since the packet is quite large fill_buffer tries to reallocate the buffer before doing nothing. Fixes bug 98.
