[FFmpeg-devel] [PATCH] avcodec/mpeg12dec: Limit maximum A53 CC size

2020-09-22 Thread Michael Niedermayer
This is more than 10 times the size of the largest i found. And also alot more than our encoder could handle (our encoder is limited to max 31) Without any limit megabyte+ sized blocks can be reallocated millions of times. Sadly the SCTE-20 spec does not seem to contain any hard limit directly, so
