The recent commits change the value slightly. Even though it's within the threshold it's better to risk as little as possible especially when different systems, processors, FPUs and compilers are involved. Signed-off-by:

Since TNS was fixed with the recent commits retweak the values so it's more frequently used. Still not enabled by default yet, though it's possible that it will be made enabled by default in the near future. Signed-off-by:

This commit was made possible with the earlier commits since the new quantization method basically means we're working always with unsigned values. The specifications mention to use compression when the first 2 bits are identical but they didn't mention if this should happen before or after the conversion to signed values. Actually they said nothing about conversion to signed values. With this commit, coefficient compression usually always happens which saves a lot of space, especially at extremely low bitrates and doesn't change the quality at all. Signed-off-by:

This finally (and again) gets rid of basically everything the specifications say about how TNS should be done. The main problem used to be that a single filter was used for all coefficients which despite being explicitly recommended by the specifications usually sounds wrong, therefore it's a corner case in the current TNS implementation. This commit also changes the coefficient bit size, as apparently it's better to use lower precision in case the windows are eight short. This is apparently what fdk_aac uses, looking at the bit stream and makes sense. Also the order when 8 SHORT windows happen is important as 7 was too much and according to PSNR was worse while 5 is just about correct. Signed-off-by:

This also drops setting the frame->pts field. This is usually not set by decoders, so this would be an inconsistency that's at worst a danger to the API user. It appears the buffer->dts field is normally not set by the MMAL decoder, so don't use it. If it's ever going to be set by MMAL, we don't know whether the value will be what we want. Signed-off-by:

The generic code in utils.c sets the AVFrame.pkt_dts field from the packet it was supposedly decoded. This does not have to be true for a fully asynchronous decoder like mmaldec. It could be overwritten with an incorrect value. Even if the decoder doesn't determine the DTS (but sets it to AV_NOPTS_VALUE), it's impossible to determine a correct value in utils.c. Decoders can now be marked with FF_CODEC_CAP_SETS_PKT_DTS, in which case utils.c won't overwrite the field. The decoders are expected to set this field (even if they only set it to AV_NOPTS_VALUE).

This MMAL feature fills in missing timestamps from the framerate set on the input port. This is generally unwanted, since libavcodec decoders merely pass through timestamps without ever "fixing" them. The framerate is also unknown, and even the timebase doesn't have to be set. Signed-off-by:

Don't try to do a blocking wait for MMAL output if we haven't even sent a single real packet, but only flush packets. Obviously we can't expect to get anything back. Additionally, don't send a flush packet to MMAL in the same case. It appears the MMAL decoder will sometimes hang in mmal_vc_port_disable() (called from ffmmal_close_decoder()), waiting for a reply from the GPU which never arrives. Either MMAL disallows sending flush packets without preceding real data, or it's a MMAL bug. Signed-off-by:

I can't come up with a nice way to handle this. It's hard to keep the lock-stepped input/output in this case. You can't predict whether the MMAL decoder will output a picture (because it's asynchronous), so you have to assume in general that any packet could produce 0 or 1 frames. You can't continue to write input packets to the decoder, because then you might get too many output frames, which you can't get rid of because the lavc decoding API does not allow the decoder to return an output frame without consuming an input frame (except when flushing). The ideal fix is a M:N decoding API (preferably asynchronous), which would make this code potentially much cleaner. For now, this hack will do. Signed-off-by:
