Ffvcl - Delphi Ffmpeg Vcl Components 5.0.1 [new] -

Based on the naming conventions and typical capabilities of the FFVCL (Delphi FFmpeg VCL Components) library, here are the core features you would expect from version 5.0.1:

Then came FFVCL.

: Features for joining multiple files, applying video filters (flip, negate, scale), and overlaying text or images on input frames. Data Handling : Direct support for PCM wave data FFVCL - Delphi FFmpeg VCL Components 5.0.1

And it still works on Windows 11. And Windows 7. And probably Windows 12, too. Based on the naming conventions and typical capabilities

Internal Behavior

Open input with avformat_open_input (fast flags: AVFMT_FLAG_IGNIDX optional).
Call avformat_find_stream_info with limited probe size derived from TimeoutMs and ProbeOnly.
For each stream, gather codec parameters (codec_id, profile, level, pix_fmt, sample_fmt, channels, sample_rate, extradata).
Verify decoder availability via avcodec_find_decoder and check hardware-accelerated decoder mapping.
If HWAccel requested, attempt to initialize hwdevice_ctx for requested backend; fall back to software if unavailable and record warning.
Determine whether pixel/sample format matches component rendering/processing capabilities; set RequiresSoftwareConversion accordingly and propose RecommendedPixelFormat.
If ProbeOnly = False, allocate minimal required buffers (small frame/audio pool), reserve internal decoder contexts but do not start decoding.
Validate container-level issues (encryption, corrupt headers) and return clear ErrorMessage/ErrorCode mapping.
Timeouts and cancellation support for long probes; background thread cooperates with main thread for event callbacks.
