* 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.

* 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>

* lavu: Remove bit packing from AVComponentDescriptorVittorio Giovara2015-09-07
| | | | | | | | | There is no practical benefit in having this structure elements bit packed given the size of the structure and its usage. Change types from uint16_t (packed) to plain int in order to simplify modifying the structure and accessing its fields. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* mov: Allow more than one keyframe per trunMartin Storsjö2015-09-06
| | | | | | | | | | | | | | | | | The previous restriction was partially designed to fix certain (broken) samples from bug 215. There should be no restriction on the number of keyframes per fragment or trun. The spec suggests that all frames lacking MOV_FRAG_SAMPLE_FLAG_IS_NON_SYNC are key frames, but we require the flag MOV_FRAG_SAMPLE_FLAG_DEPENDS_YES to be unset as well. This works for (possibly broken) media that never sets the NON_SYNC flag and should also be correct for any spec-compliant file. For files that never set either of the flags, all samples are marked as keyframes. Signed-off-by: Martin Storsjö <martin@martin.st>
