* lavc: Keep idct integer optionVittorio Giovara2015-09-13
| | | | | | "int" is useful in testing because provides accurate results across different plaftforms, so remove it from the scheduled FF_API_UNUSED_MEMBERS deprecation.

| | | | | | | | | Deprecate the now unused option, but temporarily retain the capability to disable the now default behaviour. Mention this change in the AVPacket documentation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* mmaldec: fix pkt_dts determinationwm42015-09-12
| | | | | | | | | | | | 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.

* lavc: allow asynchronous decoders to return correct pkt_dts valueswm42015-09-12
| | | | | | | | | | | | | | | 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).

* mmaldec: disable timestamp interpolationwm42015-09-12
| | | | | | | | | 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: Luca Barbato <lu_zero@gentoo.org>
* mmaldec: fix problems with flush logicwm42015-09-12
| | | | | | | | | | | | | | 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: Luca Barbato <lu_zero@gentoo.org>
* mmaldec: hack against buffering problems on broken inputwm42015-09-12
| | | | | | | | | | | | | | | | | | 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: Luca Barbato <lu_zero@gentoo.org>
