* avcodec/libzvbi-teletextdec: allow -1 subtitle duration and make it the defaultMarton Balint2018-05-06
| | | | | | | Most decoders (pgssubdec, ccaption_dec) are using -1 or UINT32_MAX for a subtitle event which should be cleared at the next event. Signed-off-by: Marton Balint <cus@passwd.hu>

* avcodec/jpeg2000dec: Reduce the number of tile parts allocatedMichael Niedermayer2018-05-06
| | | | | | | | | | | | | | This is large enough for all jpeg2000 files i tested. If some need more then this should be changed to dynamic allocation. Dynamic allocation would need to be done carefully as these are many relatively small arrays so repeatly reallocating them would not be good. The decrease is a clean and simple solution assuming it works for all files.

* avcodec/mediacodecdec: add workaround for buggy amlogic mpeg2 decoderAman Gupta2018-05-04
| | | | | | | | | | | | | | | | | | I tested the previous mediacodec changes on seven different Android TV devices, with both mpeg2 and h264 content. All except one worked as expected. The exception was the MiBox3 running Android 6.0.1, where playback would freeze on a frame every few seconds. I tested two other AMLogic devices with newer Android versions that did not show the same problem. H264 decoding on the MiBox3 was also not affected, so this workaround applies only to OMX.amlogic.mpeg2.decoder.awesome on Android API22. There is a rumor that Xiaomi is planning to release Android Oreo for the MiBox3, so I will revisit in a few months to confirm whether this is specific to os/driver version or the chipset used in that device.

* avcodec/mediacodecdec: wait on first frame after input buffers are fullAman Gupta2018-05-04
| | | | | | | | | | | The output_buffer_count==0 special case is no longer required, and can cause spurious EAGAIN to surface to the user when input buffers are filled up. Since the caller now knows if the decoder is accepting new input (via current_input_buffer>=0), let the wait parameter control whether we block or not.

* avcodec/mediacodecdec: restructure mediacodec_receive_frameAman Gupta2018-05-04
| | | | | | | | | | | | | The new logic follows a recommendation by @rcombs to use dequeueInputBuffer with a timeout of 0 as a way to detect whether the codec wants more data. The dequeued buffer index is kept in MediaCodecDecContext until it can be used next. A similar technique is also used by the Google's official media player Exoplayer: see MediaCodecRenderer.feedInputBuffer().
