mpegtsenc: make PMT PID really start on pmt_start_pid

79ee8977 04/26/2011 09:19 PM Justin Ruggles

ac3enc: correct the flipped sign in the ac3_fixed encoder

fd0c3403 04/17/2011 08:46 PM Diego Biurrun

Update regtest checksums after revision 6001dad.

The string "FFmpeg" was replaced by "Libav" in metadata that
got encoded in file headers.

96573c0d 04/12/2011 11:06 PM Vitor Sessak

lavf/utils.c: Order packets with identical PTS by stream index.

This allows for more reproducible results when using multi-threading.

Signed-off-by: Ronald S. Bultje <>

e05a3ac7 04/04/2011 12:59 AM Justin Ruggles

ac3enc: select bandwidth based on bit rate, sample rate, and number of
full-bandwidth channels.

This reduces high-frequency artifacts and improves the quality of the lower
frequency audio at low bit rates.

ac3enc: use generic fixed-point mdct

This makes the AC3 encoder use the shared fixed-point MDCT rather
than its own implementation. The checksum changes are due to
different rounding in the MDCT.

e6e98234 03/23/2011 01:08 AM Justin Ruggles

Add apply_window_int16() to DSPContext with x86-optimized versions and use it
in the ac3_fixed encoder.

323e6fea 03/14/2011 12:45 PM Justin

ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage.

This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done...

ac3enc: change default floor code to 7.

This is to match the value in every (E-)AC-3 file from commercial sources.
It has a negligible effect on audio quality.

c3beafa0 02/02/2011 08:00 PM Justin Ruggles

ac3enc: Change EXP_DIFF_THRESHOLD to 500.

This patch changes the exponent difference threshold in the exponent
strategy decision function of the AC-3 encoder. I tested lowering in
increments of 100. From 1000 down to 500 generally increased in quality
with each step, but 400 was generally much worse....
