| * x86: clean up ff_dsputil_init_mmx()Mans Rullgard2012-03-051-417/+475
| | | | | | | | | | | | | | | | This splits ff_dsputil_init_mmx() into multiple functions, one for each MMX/SSE level, somewhat simplifying the nested conditions. Signed-off-by: Mans Rullgard <[email protected]> Signed-off-by: Diego Biurrun <[email protected]>

* | Revert "wmaenc: check final frame size against output packet size"Michael Niedermayer2012-03-051-6/+4
| | | | | | | | | | | | | | | | This condition cannot happen, if it can it is a bug that MUST be fixed. And i very happily volunteer to fix it if someone reports a case to me that fails. This reverts commit 5d652e063bd3a180f9de8915e5137aa4f938846d.

| * lavc: deprecate AVCodecContext.sub_id.Anton Khirnov2012-03-049-32/+32
| | | | | | | | | | | | | | In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.
| * proresenc: give user a possibility to alter some encoding parametersKostya Shishkov2012-03-041-56/+122
| | | | | | | | | | This allows user to select quantisation matrix from different profile, stamp frames with custom vendor string and change target bitrate.

| * wmaenc: fix m/s stereo encoding for the first frameJustin Ruggles2012-03-031-1/+3
| | | | | | | | | | | | | | | | We need to set ms_stereo in encode_init() in order to avoid incorrectly encoding the first frame as non-m/s while flagging it as m/s. Fixes an uncomfortable pop in the left channel at the start of playback. CC:[email protected]
| * wmaenc: return s->block_align instead of recalculating itJustin Ruggles2012-03-031-1/+1
| |
| * wmaenc: check final frame size against output packet sizeJustin Ruggles2012-03-031-4/+6
| | | | | | | | | | | | | | Currently we have an assert() that prevents the frame from being too large, but it is more user-friendly to give an error message instead of aborting on assert(). This condition is quite unlikely due to the minimum bit rate check in encode_init(), but it is still worth having.
| * wmaenc: require a large enough output buffer to prevent overwritesJustin Ruggles2012-03-031-0/+5
| | | | | | | | | | | | | | | | The maximum theoretical frame size is around 17000 bytes. Although in practice it will generally be much smaller, we require a larger buffer just to be safe. CC: [email protected]
| * wmaenc: limit allowed sample rate to 48kHzJustin Ruggles2012-03-031-0/+6
| | | | | | | | | | | | | | | | | | ff_wma_init() allows up to 50kHz, but this generates an exponent band size table that requires 65 bands. The code assumes 25 bands in many places, and using sample rates higher than 48kHz will lead to buffer overwrites. CC:[email protected]
| * wmaenc: limit block_align to MAX_CODED_SUPERFRAME_SIZEJustin Ruggles2012-03-031-2/+6
| | | | | | | | | | | | | | | | | | | | This is near the theoretical limit for wma frame size and is the most that our decoder can handle. Allowing higher bit rates will just end up padding each frame with empty bytes. Fixes invalid writes for avconv when using very high bit rates. CC:[email protected]
