* avcodec/encoders: Remove redundant setting of AV_PKT_FLAG_KEYAndreas Rheinhardt2021-09-28
| | | | | | | It is now set generically for all those encoders whose corresponding AVCodecDescriptor has the AV_CODEC_PROP_INTRA_ONLY. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/encode: Set AV_PKT_FLAG_KEY based upon AV_CODEC_PROP_INTRA_ONLYAndreas Rheinhardt2021-09-28
| | | | | | | | | | | Currently, the AV_PKT_FLAG_KEY is automatically set for audio encoders; yet this is wrong, as both MLP and TrueHD have non-keyframes. So set it based upon AV_CODEC_PROP_INTRA_ONLY (from the corresponding AVCodecDescriptor) instead. This also sets it for some video codecs, which is intended.

* avcodec/mlpenc: Set AV_PKT_FLAG_KEY manuallyAndreas Rheinhardt2021-09-28
| | | | | | | | | | TrueHD/MLP is one of the audio formats with keyframes. Currently, the generic encoding code just sets the keyframe flag for all returned packets, yet this is wrong for these encoders and will be changed in a future commit. So set the flag here for those packets that ought to have it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/videotoolboxenc: Fixes non-B-Frame encodingNoHalfBits2021-09-27
| | | | | | | | | | | | Sets vtctx->has_b_frames to 0 if the VideoToolbox compression session will not emit B-frames (and, in consequence, no valid DTSs). Required for the handling of invalid DTSs in 'vtenc_cm_to_avpacket' (line 2018ff) to work correctly and not abort encoding with "DTS is invalid." when no B-frames are generated.

* avformat/movenc: Limit ism_lookahead to a sane valueAndreas Rheinhardt2021-09-27
| | | | | | | | There can only be a maximum of 255 entries in a tfrf tag, so using more makes no sense; moreover, several size computations can overflow in this case. Fix this by limiting it to 255. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/cafenc: Don't segfault upon allocation errorAndreas Rheinhardt2021-09-27
| | | | | | | | | | | | | | | | | | | If an array for the packet sizes could not be successfully reallocated when writing a packet, the CAF muxer frees said array, but does not reset the number of valid bytes. As a result, when the trailer is written later, avio_write tries to read that many bytes from NULL, which segfaults. Fix this by not freeing the array in case of error; also, postpone writing the packet data after having successfully (re)allocated the array, so that even on allocation error the file can be correctly finalized. Also remove an unnecessary resetting of the number of size entries used at the end. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/cafenc: Fix potential integer overflowAndreas Rheinhardt2021-09-27
