This commit fixes two issues: 1. ATSC CC data in private MPEG-2 streams (stream type 0x06) was not being processed. The code returned CCX_PRIVATE_MPEG2_CC buffer type which was never properly implemented - it just dumped debug output and returned placeholder bytes. Fix: Treat ATSC CC in private MPEG-2 streams the same as in user-private streams (0x80-0x8F) by returning CCX_PES buffer type. Both contain the same CC data format and should use the same processing path. 2. Several dump() calls were using CCX_DMT_GENERIC_NOTICES which is enabled by default, causing binary output to flood the terminal when processing certain files. Fix: Changed to appropriate debug-only masks (CCX_DMT_VERBOSE, CCX_DMT_PARSE) so binary dumps only appear when debug mode is explicitly enabled. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Summary
Changes
1. ATSC CC in private MPEG-2 streams now works
Previously,
CCX_PRIVATE_MPEG2_CCbuffer type was created but never properly implemented. It would dump raw data and return placeholder bytes instead of actually processing the captions.Fix: Both private MPEG-2 streams (0x06) and user-private streams (0x80-0x8F) with ATSC CC codec now return
CCX_PESbuffer type and use the same processing path.2. Debug output no longer floods terminal
Several
dump()calls were usingCCX_DMT_GENERIC_NOTICESwhich is enabled by default, causing binary hex dumps to appear during normal operation.Fix: Changed to appropriate debug-only masks:
avc_functions.c: SEI error dumps →CCX_DMT_VERBOSEgeneral_loop.c: Unrecognized header dumps →CCX_DMT_PARSETest plan
