These are just for prefixes and may be hardcoded easily; see lavu/eval for this approach. Reviewed-by:

This commit for qtpalette.c and qtpalette.h adds 1-bit video to the "palettized video" category, since if the video sample description contains a palette, the two colors in the palette can be any color, not necessarily black & white. Unfortunately, I've noticed that the qtrle (QuickTime Animation) decoder blindly assumes that 1-bit video is black & white. I don't have enough knowledge about the decoder to fix this, though. Below is a link to a sample 1-bit QuickTime Animation clip of a rotating earth that uses blueish colors, and they will be correctly rendered in QuickTime, but not in FFmpeg (which will use black & white). https://drive.google.com/open?id=0B3_pEBoLs0faUlItWm9KaGJSTEESigned-off-by:

get_ue_golomb() cannot decode values larger than 8190 (the maximum value that can be golomb encoded in 25 bits) and produces the error "Invalid UE golomb code" if a larger value is encountered. Use get_ue_golomb_long() instead (which supports 63 bits, up to 4294967294) when valid h264/hevc values can exceed 8190. This updates decoding of the following values: (maximum) first_mb_in_slice 36863* for level 5.2 abs_diff_pic_num_minus1 131071 difference_of_pic_nums_minus1 131071 idr_pic_id 65535 recovery_frame_cnt 65535 frame_packing_arrangement_id 4294967294 frame_packing_arrangement_repetition_period 16384 display_orientation_repetition_period 16384 An alternative would be to modify get_ue_golomb() to handle encoded values of up to 49 bits as was done for get_se_golomb() in a92816c4. In that case get_ue_golomb() could continue to be used for all of these except frame_packing_arrangement_id. Signed-off-by:

Replaces by real arithmetic. Tested the validity of these transformations separately. Numerical differences are ~1e-15, and should not matter: it is not even clear which is more precise mathematically. Reviewed-by:

Previosly output was almost useless because background noise, due to windowing function picked and which is not actually present in audio, had too much brightness. Now output of sine wave matches more with SoX. Signed-off-by:

This solves the problem discussed in https://ffmpeg.org/pipermail/ffmpeg-devel/2015-September/179238.html by allowing AVCodec::write_header to be delayed until after packets have been run through required bitstream filters in order to generate global extradata. It also provides a mechanism by which a muxer can add a bitstream filter to a stream automatically, rather than prompting the user to do so.

Palettized QuickTime video in Matroska has hitherto not been recognized whatsoever, and the "palette" used has been completely random. The patch for matroskadec.c fixes this issue by adding a palette side data packet in matroska_deliver_packet(), much in the same way as it's done in mov.c. Video samples for testing are available at https://drive.google.com/open?id=0B3_pEBoLs0faWElmM2FnLTZYNlk. Signed-off-by:

This consists mainly of moving the palette handling from the mov_parse_stsd_video() function to a new ff_get_qtpalette() function in the new file qtpalette.c, which will be shared by both matroskadec.c and mov.c. Signed-off-by:
