This is suitably fast and satisfies the lossless +goal, while still having some compression. These can be transcoded to +FFV1 with no quality loss offline. +--- + src/pipewirerecord.cpp | 12 ++++++++---- + 1 file changed, 8 insertions(+), 4 deletions(-) + +diff --git a/src/pipewirerecord.cpp b/src/pipewirerecord.cpp +index ac8132e..232bbd6 100644 +--- a/src/pipewirerecord.cpp ++++ b/src/pipewirerecord.cpp +@@ -301,10 +301,14 @@ void PipeWireRecordProduce::setupStream() + m_avCodecContext->height = size.height(); + m_avCodecContext->max_b_frames = 1; + m_avCodecContext->gop_size = 100; +- if (m_codec->pix_fmts && m_codec->pix_fmts[0] > 0) { +- m_avCodecContext->pix_fmt = m_codec->pix_fmts[0]; ++ if (QStringLiteral("magicyuv") == QString::fromUtf8(m_encoder)) { ++ m_avCodecContext->pix_fmt = AV_PIX_FMT_YUV444P; + } else { +- m_avCodecContext->pix_fmt = AV_PIX_FMT_YUV420P; ++ if (m_codec->pix_fmts && m_codec->pix_fmts[0] > 0) { ++ m_avCodecContext->pix_fmt = m_codec->pix_fmts[0]; ++ } else { ++ m_avCodecContext->pix_fmt = AV_PIX_FMT_YUV420P; ++ } + } + m_avCodecContext->time_base = AVRational{1, 1000}; + +@@ -462,7 +466,7 @@ QByteArray PipeWireRecord::encoder() const + + QList<QByteArray> PipeWireRecord::suggestedEncoders() const + { +- QList<QByteArray> ret = {"libvpx", "libx264"}; ++ QList<QByteArray> ret = {"libvpx", "libx264", "magicyuv"}; + std::remove_if(ret.begin(), ret.end(), [](const QByteArray &encoder) { + return !avcodec_find_encoder_by_name(encoder.constData()); + }); +-- +2.43.2 + |
