What's new in 8.1.7

• Critical fix — audio pipeline: av_opt_set_int(abuffersink, "all_channel_counts", 1) called a removed FFmpeg 8.x option, aborting every audio filter graph with Conversion failed!. Upgrade strongly recommended.
• JNI memory leak in registerNewNativeFFmpegPipe fixed
• getVersion() now returns "8.1-lts" correctly

---

Known limitations

• arm64-v8a only — other ABIs require compiling from source via android.sh
• -ac N flag removed — use -af "aformat=channel_layouts=mono" instead (FFmpeg 8.x broke runtime -ac)
• pkt_pos / pkt_size in ffprobe always return N/A (removed from AVFrame in FFmpeg 8.x)
