From e4b5793633964c1508d0e84ae79314b331ef1a0c Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 6 Apr 2022 09:53:53 +0100 Subject: [PATCH] media: coda: jpeg: start streaming without valid header Stop bailing out on JPEG header parsing errors during streamon. This allows userspace to provide valid output buffers later and fixes a v4l2-compliance streaming test failure: fail: v4l2-test-buffers.cpp(1429): node->streamon(q.g_type()) test MMAP (no poll): FAIL Signed-off-by: Philipp Zabel Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/chips-media/coda-common.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/media/platform/chips-media/coda-common.c b/drivers/media/platform/chips-media/coda-common.c index 3eaf0e7e6b20..7b4942bb6c2c 100644 --- a/drivers/media/platform/chips-media/coda-common.c +++ b/drivers/media/platform/chips-media/coda-common.c @@ -1999,9 +1999,13 @@ static int coda_start_streaming(struct vb2_queue *q, unsigned int count) */ if (q_data_src->fourcc == V4L2_PIX_FMT_JPEG) { buf = v4l2_m2m_next_src_buf(ctx->fh.m2m_ctx); - ret = coda_jpeg_decode_header(ctx, &buf->vb2_buf); - if (ret < 0) - goto err; + coda_jpeg_decode_header(ctx, &buf->vb2_buf); + /* + * We have to start streaming even if the first buffer + * does not contain a valid JPEG image.
